ual. You should read it before you start installing the system, so you don't have to rush to finish the work. Keep all the components of the WG20 system handy so that you can read, check and verify all the information contained in this manual. How-

ever, do not carry out the adjustment and memorization stages other-

wise, during the actual installation of the products, you will have to deal with settings that differ from the original factory ones. When reading this manual, pay special attention to the sections marked by the following symbol:

these sections are particularly important for safety. Store this manual safely for future use. This manual, as well as the design and manufacture of the devices that make up WG20, comply fully with the standards and regulations in force. Considering the hazards that may exist during the installation and operation of WG20, it is necessary that also the installation be carried out in strict compliance with current legislation, standards and regulations, particularly:

This manual contains important information regarding personal safety; before you start installing the components, it is important that you read and understand all the information contained here-

in. Do not proceed with the installation if you have doubts of any sort; if necessary, refer to the MHOUSE customer service depart-

ment for clarifications. Before you start with the installation, make sure that each sin-

gle WG20 device is suitable for the intended automation purpos-

es; pay special attention to the data provided in chapter 6 "Tech-

nical Characteristics". If even a single device is not suitable for the intended application, do not proceed with the installation. The WG20 automation system cannot be considered as a suit-

able intrusion protection system. If you require efficient protec-

tion you need to integrate WG20 with other devices. The packing materials for WG20 must be disposed of in com-

pliance with local regulations. Do not make modifications to any components unless provided for in this manual. This type of operations will only cause mal-

functions. MHOUSE disclaims any liability for damage resulting from modified products. Do not immerse the automation parts in water or any other liq-

uid. During installation, ensure that water does not leak into the control unit or other open devices. In the event that liquid substances have penetrated inside the automation devices, immediately disconnect the power supply and contact the MHOUSE customer service department. The use of WG20 in these conditions can be dangerous. Keep all components of WG20 away from heat sources and open flames; these could damage the components and cause malfunctions, fire or dangerous situations. During long periods of inactivity, the optional battery (PR1) should be removed and stored in a dry location to prevent leak-

age of noxious substances. Connect the control unit only to a power supply line equipped with safety grounding system. All operations requiring the opening of the protection shell of any WG20 device must be performed with the control unit dis-

connected from the power supply (and from the PR1 buffer bat-

tery, if featured); if the disconnection device is not identifiable, post the following sign on it: "WARNING: MAINTENANCE WORK IN PROGRESS". In the event that any automatic switches or fuses are tripped, you must identify the failure and eliminate it before you reset them. Before you start with the installation, check whether additional devices or materials are needed to complete the automation with WG20 based on the specific application requirements. If a failure occurs that cannot be solved using the information provided in this manual, refer to the MHOUSE customer service department. The WG20 automation system must not be used until the automation has been commissioned as described in paragraph 3.7.2 "Commissioning". WG20 Instructions 3 2 Product description 2.1 Applications WG20 is a set of components designed for the automation of single-leaf or double-leaf gates in residential applications. Any applications other than those described above or under dif-

ferent conditions from those specified in this manual are forbid-

den. 2.2 Description of the automation WG20 operates with electric power. In the event of a power failure, the gearmotor can be released using suitable keys in order to move the gate manually. Alternatively, the PR1 buffer battery (optional accessory) can be used. The following example of a typical WG20 application will serve to clarify a few terms and aspects of a gate automation system:

(*) the screws needed to secure the front and rear brackets are not supplied because their type depends on the material and thickness of the gate. 2.3.1 WG10 Electromechanical Gearmotors WG10 is an electromechanical gearmotor consisting of a worm screw reduction gear and a 24Vdirect current motor. It features a key-operated mechanical release mechanism that allows you to move the gate manu-

ally in the event of a power failure. The gearmotor is fitted with four mounting brackets (two at the front and two at the rear) and an adjustable stop (small plates that can be loos-

ened and adjusted on the teeth to limit the opening stroke) that offers trouble-free installation in all conditions.

(optional), which is necessary for operation in case of power failure. The CL20 control unit can actuate the gearmotors with two speeds:

"slow" and "fast". The three P1, P2 and P3 buttons [C] and the corresponding LED's are used to program the control unit. To facilitate the electrical connections there are separate terminals for each device [A], which are removable and colour-coded based on the function performed. Next to each input terminal there is a LED that sig-

nals its status. The connection to the power supply is very easy: just insert the plug in a power outlet.

It cannot solve defects resulting from incorrect installation or poor maintenance of the gate. Using the leaf opening angle as a guideline, check that the values in Table 6 can be met. Before proceeding with the installation you must:

Make sure that the weight and dimensions of the gate fall within the specified operating limits. If they do not, WG20 cannot be used. Make sure that the structure of the gate is suitable for automation and in compliance with regulations in force. Make sure that there are no points of greater friction in the opening or closing travel of the gate leaves. Make sure that the gate is well balanced: it must not move by itself when it is placed in any position. Table 6 Make sure that the mounting positions of the various devices are protected from impacts and that the surfaces are sufficiently sturdy. Make sure that the mounting surfaces of the photocells are flat and that they enable the proper alignment between TX and RX. Check the size limits referring to Figure 10. Figure 10 Make sure there is enough space even when the gate is open.

t h g e w i f a e l m u m x a M i Figure 12 Maximum leaf length (m)

"C" depends on how the rear bracket is mounted (see Figure 17) and may vary from 53 mm to 176 mm. It is normally about 150mm.

"D" is easy to measure on the gate.

"A" is the sum of "C" and "D". The value of "B" can be calculated from the value of "A" and the opening angle of the leaves. For example: if "A" is 150mm and the opening angle of the leaves is 100, the value of "B" is about 150mm. Make sure that "B" is equal or similar to "A". This ensures the leaf moves smoothly, thereby reducing the strain on the gearmotor. WG20 Instructions 7 Figure 11 3.1.1 Operating Limits Chapter 6 "Technical Characteristics" provides the fundamental data needed to determine whether all the WG20 components are suitable for the intended application. In general, WG20 is suitable for the automation of gates featuring leaves up to 4,5m wide, weighing up to 400 kg, with opening angle of up to 130 for residential applications. 3.1.2 Tools and Materials Make sure you have all the tools and materials needed to install the system; make sure that they are in good condition and serviceable according to current safety standards. See examples in Figure 13. The shape of the gate and the climatic conditions (e.g. presence of strong wind) may reduce these maximum limits. In this case it is necessary to measure the torque needed to move the leaves under the worst conditions, and to compare it to the data provided in the technical characteristics chart for the WG20 gearmotor. 3.1.3 List of Cables Figure 13 The cables required for the installation of WG20 may vary depending on the type and quantity of devices to be installed; figure 14 shows the cables needed for a typical installation; no cable is supplied with WG20.

Note 1 A power supply cable longer than 30 m may be used provided it has a larger gauge, e.g. 3x2.5mm2, and that a safety grounding system is provided near the automation unit. Note 2 For the ESCbus, STOP and OPEN cables, there are no special contraindications to the use of a single cable that groups together multiple connections; for example, the STOP and OPEN inputs can be connected to the KS1 selector switch using a single 4x0,5mm2 cable. 8 WG20 Instructions 3.2 Preparing the Electrical System With the exception of the power line that supplies the control unit, the rest of the system uses extra-low voltage (approx. 24V); the wiring can therefore be done by personnel that is not properly qualified, provided that all the instructions in this manual are carefully observed. After selecting the position of the various devices (refer to figure 1) you 3.2.1 Connection to the Electrical Mains Although the connection of WG20 to the electrical mains is beyond the scope of this manual, we wish to remind you that:

The power supply line must be laid and connected by a qualified professional electrician. Alternatively, have a suitably protected 16A "shuko" outlet installed, where you can plug in WG20. 3.3 Installation of the Various Devices 3.3.1 WG10 gearmotor mounting 1 Choose the mounting position in accordance with the specifications in paragraph 3.1 "Preliminary Checks". 2 Check that the mounting surface is perfectly smooth, vertical and sufficiently compact. WG10 does not come with a mounting system, consequently one will have to be chosen according to the surface material. 3 Lay the conduit for the power cable. can start preparing the conduits for the electrical cables connecting the devices to the control unit. The conduits are designed to protect the electrical cables and prevent accidental breakage, which may be caused by the passage of vehicles, for instance. The electric line must be grounded and protected against short circuits; a bipolar disconnection device must also be present with contact separation of at least 3 mm, which allows the power sup-

ply to be disconnected during the installation and maintenance of the WG20. 6 To obtain the front support, assemble two brackets and the front plate as shown in Figure 18. Figure 18 7 Remove the back cover of the gearmotors by sliding it in the direction of the arrows. 8 Move the leaves to the "gate closed" position. Figure 15 4 To obtain the rear supports, assemble two brackets and the rear plate as shown in Figure 16. 5 To obtain different "C" values (see Figure 12) assemble the brackets and plate as shown in Figure 17. Figure 16 Figure 19 9 Referring to the "B" distance calculated from Table 6, place the rear support in the correct position on the mounting surface, Check that there is a suitable surface at the values in Figure 22, i.e. where the front support is mounted. 10 Mark the drill points for the rear support using the support itself as a reference point. Drill holes in the mounting surface for 4 anchors [A] with a diameter of at least 8 mm (not included in supply). Fix the plate with suitable screws [C] and washers [B]. Figure 17 A B C Figure 20 WG20 Instructions 9 11 Check that the plate is perfectly level, the slots on the bracket allow small differences in alignment to be corrected. 17 Fix the gearmotor to the front support and anchor it with the screw [I]

and washer [H]. Fully tighten the screw. Figure 21 12 Referring to Figure 22, place the front support at a distance of 820 mm from the rear support and 38 mm lower. H I Figure 25 18 Release the gearmotors using the appropriate release keys (see the

"Gearmotor Release" paragraph on page 34). 19 Test the mechanism by moving the gate by hand. Check that the fork slides perfectly on the worm screw of the gear motor and that there remains a margin of at least 5 mm from the opening and closing stops, making sure, however, that not too much of the worm screw remains unused. 20 If necessary, test the other assembly positions allowed by the front and rear plates. See Figure 17. 21 If necessary, adjust the stops by loosening them with Allen keys [N]

and moving them to the required position. The opening stop [L] is used if there are no opening stops on the ground. Normally, the leaves stop against the closing stop during the closing manoeuvre. After adjusting the stops, fully tighten the screws. Figure 22 13 Temporarily fix the front support to the leaf with a clamp. L N Figure 26 22 Secure the front support permanently using screws suited to the material of which the gate is constructed. Figure 23 23 Fix the gearmotor once more using the appropriate release keys (see the "Gearmotor release" paragraph on page 34). 14 Lift up the gearmotor and fit the fork into the hole in the front support. 15 Keep the gearmotor lifted and pull it to open the gate until the hole in the plate matches the hole in the gearmotor. Fix the gearmotor to the rear support [E] with the screw [D], nut [G] and washer [F]. 24 Thread the electrical cable through the conduit and bring it to the control unit. N.B.: the cable leaving the gear motor must be curved so that it can follow the gearmotor when it rotates to open and close the leaf. D E F G Figure 24 16 Firmly tighten the nut and then loosen it by about half a turn in order to allow the gearmotor to rotate on the support. Figure 27 10 WG20 Instructions 25 Loosen the cable gland under the gearmotor, push the power cable through and then firmly close the cable gland. 27 Close the back cover of the gearmotors by inserting it in the direction of the arrows. 26 Make electrical connections as follows. brown yellow-green blue Figure 28 3.3.2 Photocells 1 Select the position of the two elements that make up the photocell (TX and RX) observing the following directions:

Position them at a height of 40-60 cm from the ground, on both sides of the area to be protected, on the street side of the installation and as close as possible to the edge of the gate, no farther than 15 cm. Point transmitter TX towards receiver RX, with a maximum tolerance of 5. In the selected locations there must be a conduit for threading the cables. 2 Remove the front glass [A] by prising it out with a slotted tip screwdriver applied to the bottom. Figure 29 7 Secure the bottom with the screws [C]. B C D C A Figure 32 8 Connect the electric cable to the appropriate TX and RX terminals.

terminals as shown in figure 43. You do not need to observe any polarity on the FLASH terminal; however, for the connection of the shielded cable to the aerial, connect the braid as shown in figure 44. The terminals can be removed in order to facilitate the operations; make the connections and then reinsert them. Figure 43 Figure 44 3.3.5 CL20 Control Unit 1 Select the installation position in a location protected from possible impacts and near the gate so that the length of the cables can be reduced. 2 Remove the cover by prising it open with a screwdriver applied to the bottom opening, slide it out a few centimetres and then lift it from the bottom . Figure 45 Figure 46 3 Arrange the conduit for the electric cables so that they can be let in through the bottom of the control unit as shown in figure 47. 4 Drill a hole through the bottom of the control unit and use suitable unions to fasten the conduits for the electric cables. 5 Breach the two bottom holes using a screwdriver, then mark the drilling points using the bottom as reference. Figure 47 6 Drill the holes in the wall using a hammer drill with a 6 mm bit and insert the 6 mm screw anchors 7 Secure the bottom with the appropriate screws [A]. A Figure 48 WG20 Instructions 13 8 Refer to figure 49 for the electrical extra low voltage connection of the various devices to the CL20 control unit terminals. The terminals have the same colour coding as the corresponding devices; for example, the grey terminal (OPEN) of the KS1 selector switch must be connected to the grey terminal (OPEN) of the control unit. For most connections you do not need to observe any polarity; only for the shielded cable of the aerial it is necessary to connect the central core and the shield as shown in detail [B]. The cable for the motors must be connected as shown in detail [A]. Keep in mind that, to prevent the jamming of the two leaves, the control unit commands the M2 motor to open first, followed by M1 (vice-

versa for the closing manoeuvre). Therefore make sure that the motor that drives the leaf that strikes the mechanical stop is connected to terminal M1 (outer one), while the motor that drives the other leaf must be connected to terminal M2. If only one motor is used (single-leaf gate) it must be connected to terminal M2 while terminal M1 remains free. FL1 PH1 PH1 KS1 B WG10 M2 WG10 M1 brown yellow/green blue A brown yellow/green blue To facilitate the installation operations, the terminals [B] can be removed as shown in figure 49; make the connections and then re-insert them. When you have completed the connections, use clamps to secure the cables to the appropriate fasteners [C]. 9 To close the control unit you need to rest the cover on the bottom approximately 3 cm above the final position, then press it down until it snaps into place. Figure 49 C B Figure 50 14 WG20 Instructions Figure 51 3.4 Power Supply Connection The connection of the CL20 control unit to the mains must be made by a qualified electrician. To carry out tests, insert the plug for CL20 in a power outlet; if neces-

sary, use an extension cord. The CL20 control unit must be permanently connected to the mains power supply for the testing and commissioning operations. This operation must be performed as follows by a qualified electrician:

1 Make sure that the plug of the CL20 control unit is not plugged into the power socket 2 Disconnect the power cable from the CL20 control unit power supply terminal 3 Slacken the collar close to the terminal and remove the cable 4 Insert the final power supply cable of the control unit through the collar 5 Connect the cable to the terminal of the control unit 6 Tighten the collar 3.5 Initial checks Figure 52 As soon as the CL20 control unit is energized, you should check the following:

3 Make sure that the night light [C] on the KS1 key-operated selector switch is on. 1 Make sure that the "ECSBus" LED [A] flashes regularly, with about one flash per second. A C Figure 53 2 Make sure that the SAFE LED [B] on the photocells flashes (both on TX and RX); the type of flashing is not important as it depends on other factors;

what is important is that the LED should not be steadily on or steadily off. B Figure 54 3.5.1 Recognition of Connected Devices When you have completed the initial checks, the control unit must recognize the devices connected to it on the "ECSBus" and "STOP"

terminals. 1 On the control unit, press the P2 button [C] and hold it down for at least three seconds, then release the button. 2 Wait a few seconds for the control unit to finish recognizing the devices. 3 When the learning procedure is completed, the STOP LED [A] must remain on, while the P2 LED [B] must go off. If the P2 LED flashes it means that an error has occurred: see paragraph 5.5 "Troubleshooting". The connected devices recognition stage can be repeated again at any time, even after the installation (for example, if an additional photocell is installed); just repeat the procedure starting from step 1. Figure 55 4 If the above conditions are not satisfied, you should immediately switch off the power supply to the CL20 control unit and check the cable connections more carefully. For more useful information see also chapters 5.5 "Troubleshooting" and 5.6 "Diagnostics and Signals". A B C Figure 56 WG20 Instructions 15 3.5.2 Recognition of Gate Leaves' Opening and Closing Angles After recognizing the devices, the control unit must learn to recognize the leaves' opening and closing angles . During this stage, the leaves' opening angle is measured from the closing mechanical stop to the opening mechanical stop. Fixed and sufficiently sturdy mechanical stops are required. If any device is triggered during the recognition stage (photocells, key-

operated selector switch, pressure on P3, etc.), the recognition stage will immediately be interrupted. It will therefore be necessary to start again from the beginning. 3 If at the conclusion of the search the P3 LED [A] flashes, it means that an error has occurred; see paragraph 5.5 "Troubleshooting". 1 Release the motors using the appropriate keys (see the "Gearmotor Release" paragraph on page 34) and move the leaves to mid travel so that they are free to move in both opening and closing directions; then lock the motors. 2 On the control unit press the P3 button [B] and hold it down for at least three seconds, then release the button. Wait for the control unit to complete the recognition stage: closing of the M1 motor to the mechanical stop, closing of the M2 motor to the mechanical stop, opening of the M2 and M1 motors to the opening mechanical stop; complete closing of M1 and M2. If the first manoeuvre of one or both leaves is not to close, press P3 to interrupt the recognition stage, then switch the polarity of the motor/s that opened by exchanging the two brown and blue wires on the terminal. If the first motor to move in the closing direction is not M1, press P3 to interrupt the recognition stage, then switch the motor connections on the terminals. 3.5.3 Checking the Radio Transmitters To check the transmitters just press one of the four buttons, make sure that the red LED flashes and that the automation executes the command. The command associated to each button depends on how they have been memorized (see paragraph 5.4 "Memorization of Radio Transmitters"). The transmitters supplied have already been memorized and when you press the buttons the following commands are transmitted:

Button T1 Button T2 Button T3 Button T4

"OPEN" command

"Open pedestrian gate" command

"Open only" command

"Close only" command 3.6 Regulations 3.6.1 Selecting the Speed of the Leaf The leaves can be opened and closed at two speeds: "slow" or "fast". To switch from one speed to the other press the P2 button [B]

momentarily; the corresponding P2 LED [A] will light up or go off; if the LED is off the speed is "slow", if the LED is on the speed is "fast". 16 WG20 Instructions A B Figure 57 The opening angles recognition stage can be repeated again at any time, even after the installation (for example, if one of the opening stops is moved); just repeat the procedure starting from step 1. T1 T2 T3 T4 Figure 58 A B Figure 59 3.6.2 Selecting the Type of Operating Cycle The opening and closing of the gate can take place according to different operating cycles:

Single cycle (semiautomatic): the gate opens with a command and stays open until the next command is given, causing it to close. Complete cycle (automatic closing): the gate opens with a command and then closes automatically after a short time (for the time, see paragraph 5.1.1 "Adjusting the Parameters with the Radio Transmitter"). To switch from one operating cycle to the other, press the P3 button [B]

momentarily; the corresponding LED [A] will light up or go off; if the LED is off the cycle is "single", if the LED is on the cycle is "complete". 3.7 Testing and commissioning These are the most important operations, designed to guarantee the maximum safety and reliability of the automation system. The testing procedure can also be used as a periodic check of the devices that make up the automation. 3.7.1 Testing 1 Make sure that the provisions contained in chapter 1

"WARNINGS" have been carefully observed. 2 Using the selector switch or the radio transmitter, test the opening and closing of the gate and make sure that the leaves move in the intended direction. The test should be carried out a number of times to make sure that the gate moves smoothly, that there are no points of excessive friction and that there are no defects in the assembly or adjustments. 3 Check the proper operation of all the safety devices, one by one

(photocells, sensitive edges, etc.). In particular, each time a device is activated the "ECSBus" LED on the control unit flashes for a longer time, confirming that the control unit recognizes the event. 4 To check the photocells and make sure that there is no interference with other devices, pass a 5 cm diameter, 30 cm long cylinder on the optical axis, first near TX, then near RX and finally at the mid-point between them and make sure that in all these cases the device is triggered, switching from the active to the alarm status and vice-versa;

finally, that it causes the intended action in the control unit, for example that it causes the reversal of the movement during the closing manoeuvre. 3.7.2 Commissioning The commissioning operations can be performed only after all the tests have been successfully carried out. Partial commissioning or implementation of "temporary" conditions are not permitted. 1 Prepare the technical documentation for the automation, which must include at least: assembly drawing (e.g. figure 1), wiring diagram (e.g. figure 14), analysis of hazards and solutions adopted, manufacturer's declaration of conformity of all the devices installed. For WG20 use Annexe 1 "EC Declaration of Conformity of the WG20 components". 2 Post a label on the gate providing at least the following data: type of automation, name and address of manufacturer (person responsible for the "commissioning"), serial number, year of manufacture and "CE"

marking. A B Figure 60 The testing and commissioning operations must be performed by qualified and experienced personnel who must establish what tests should be conducted based on the risks involved, and verify the compliance of the system with applicable regulations, legislation and standards, in particular with all the provisions of EN 12445 standard which establishes the test methods for gate automation systems. Figure 61 5 Measure the impact force according to EN 12445 standard. If "motor force" control is used to assist the system for the reduction of the impact force, try to find the adjustment that gives the best results. 3 Fill out the declaration of conformity and deliver it to the owner of the automation system; for this purpose you can use Annexe 2 "EC Declaration of Conformity". 4 Prepare the operating guide and deliver it to the owner of the automation system; Annexe 3 "OPERATING GUIDE" can be used as an example. 5 Prepare the maintenance schedule and deliver it to the owner of the automation system;

the maintenance of all the automation devices. it must provide directions regarding 6 Before commissioning the automation system inform the owner regarding dangers and hazards that are still existing. Istructions WG20 17 4 Maintenance The maintenance operations must be performed in strict compliance with the safety directions provided in this manual and according to the applicable legislation and standards. The devices used for the WG20 automation system do not require any special maintenance. However, periodically make sure (at least once every six months) that all the devices are perfectly efficient. To this end, carry out all the tests and checks described in paragraph 3.7.1 "Testing"

4.1 Dismantling and Disposal WG20 is constructed of various types of materials, some of which can be recycled (aluminium, plastic, electric cables), while others must be disposed of (electronic boards). WARNING: some electronic components may contain polluting substances; do not pollute the environment. Enquire about the recycling or disposal systems available for WG20 in compliance with regulations locally in force. 1 Contact a qualified electrician regarding the disconnection of the automation system from the electric mains. and the operations described in paragraph 7.3.3 "Maintenance Operations to Be Performed by the User". If other devices are present, follow the directions provided in the corresponding maintenance schedule. 2 Disassemble all the devices and accessories, following in reverse order the procedures described in chapter 3 "Installation". 3 Remove the batteries from the radio transmitters. 4 Remove the electronic boards. 5 Sort the various electrical and recyclable materials and consign them to licensed firms for recovery and disposal. 6 Consign the remaining materials to authorized scrap collection centres. 18 WG20 Instructions 5 Additional information The following chapters describe different ways of customizing WG20 to make it suitable for specific application requirements. 5.1 Advanced Adjustments 5.1.1 Adjusting the Parameters with the Radio Transmitter The radio transmitter can be used to adjust certain control unit operation parameters: there are four parameters and each of them can have four different values:

1) Pause time: time during which the leaves remain open (in the automatic closing mode). 2) Pedestrian gate: pedestrian gate opening mode. 3) Motor force: maximum force beyond which the control unit recognizes an obstacle and reverses the movement. 4) "OPEN" function: sequence of movements associated to each

"OPEN" command. Table 8 Parameter Pause time Pedestrian gate Motor force N 1st 2nd 3rd 4th 1st Setting 10s 20s (*) 40s 80s Open 1 leaf half way 2nd open 1 leaf all the way (*) 3rd 4th 1 2nd 3rd 4th 1st open 2 leaves 1/4 of the way open 2 leaves half way Low Medium-low (*) Medium-high High

(*) Original factory setting The parameter adjustment operation can be performed using any of the radio transmitters, provided they are memorized in mode 1 like the ones supplied (see paragraph 5.4.1 "Mode 1 memorization"). In the event that no transmitter memorized in Mode 1 is available, it is possible to memorize one just for this stage and delete it immediately afterwards (see paragraph 5.4.4 "Deleting a radio transmitter"). WARNING: when using the transmitter to make adjustments you need to give the control unit time to recognize the radio command; this means that the buttons must be pressed and released slowly, held down for at least one second, then released for one second and so on. 1 Press buttons T1 and T2 on the radio transmitter simultaneously for at least 5s. 2 Release the two buttons. Action: operation to be performed at point 3 in the adjustment phase Press button T1 once Press button T1 twice Press button T1 three times Press button T1 four times Press button T2 once Press button T2 twice Press button T2 three times Press button T2 four times Press button T3 once Press button T3 twice Press button T3 three times Press button T3 four times Press button T4 once Press button T4 twice Press button T4 three times Press button T4 four times 3 Within 3 seconds, perform the action described in Table 8 based on the parameter to be modified Example: to set the pause time at 40 s. 1st 2nd 3rd Press buttons T1 and T2 and hold them down for at least 5s Release T1 and T2 Press button T1 three times All the parameters can be adjusted as required without any contraindication; only the adjustment of the "motor force" requires special care:

Do not use high force values to compensate for points of abnormal friction on the gate. Excessive force can compromise the operation of the safety system or damage the leaf. If the "motor force" control is used to assist the impact force reduction system, measure the force again after each adjustment in compliance with EN 12445 standard. The weather conditions may affect the movement of the leaf, therefore periodic re-adjustments may be necessary. Figure 62 WG20 Instructions 19 5.1.2 Checking the Adjustments with the Radio Transmitter With a radio transmitter memorized in mode 1, the adjustment values for each parameter can be checked at any time using the following sequence:

Table 9 Parameter Action Pause time Press button T1 and hold it down Pedestrian gate Press button T2 and hold it down Motor force Press button T3 and hold it down

"OPEN" function Press button T4 and hold it down Example. If the flashing light flashes three times after you have pressed T1 and T2 for 5s and then button T1, the pause time is set at 40s. PT50: Pair of 500 mm posts with one photocell PT100: Pair of 1000 mm posts with two photocells For information on the new accessories, refer to the MHOUSE catalogue or visit the site www.mhouse.biz. The CL20 control unit recognizes to recognize all the connected devices individually through a suitable recognition process, and can detect all the possible abnormalities with absolute precision. For this reason, each time a device connected to ECSBus is added or removed the control unit must go through the recognition process; see paragraph 5.3.3

"Recognition of Other Devices". Note 2. Any number of NO devices can be connected to each other in parallel. Note 3. Any number of NC devices can be connected to each other in series. Note 4. Only two devices with 8.2K constant resistance output can be connected in parallel; if needed, multiple devices must be connected "in cascade" with a single 8.2K termination resistance. Warning: if the STOP input is used to connect devices with safety functions, only the devices with 8.2K constant resistance output guarantee the fail-safe category 3. During the recognition stage the control unit, like ECSBus, recognizes the type of device connected to the STOP input; subsequently it commands a STOP whenever a change occurs in the learned status. 1 Press buttons T1 and T2 on the radio transmitter simultaneously for at least 5s. 2 Release the two buttons. 3 Within 3 seconds, perform the action described in Table 9 based on the parameter to be checked. 4 Release the button when the flashing light starts flashing. 5 Count the flashes and, based on their number, check the corresponding value in Table 8. 5.2 Optional Accessories In addition to the devices featured in WG20, other ones are available as optional accessories designed to enhance the automation system. PR1: 24V buffer battery for supply in the event of power failure. It guar-

antees at last 5 complete cycles. When the system is powered by the battery, the manoeuvre takes place only in "slow" speed mode. 5.3 Adding or Removing Devices Devices can be added to or removed from the WG20 automation sys-

tem at any time. Do not add any devices until you have made sure that they are perfectly compatible with WG20; for further information contact MHOUSE Customer Service. 5.3.1 ECSBus ECSBus is a system that allows you to connect the ECSBus devices using only two wires which carry both the power supply and the com-

munication signals. All the devices are connected in parallel on the 2 wires of the ECSBus itself; each device is individually recognized because a univocal address is assigned to it during the installation. The photocells, as well as other devices that adopt this system, can be connected to ECSBus, such as safety devices, control buttons, sig-

nalling lights etc. For information on the ECSBus devices, refer to the MHOUSE catalogue or visit the site www.mhouse.biz. 5.3.2 STOP Input STOP is the input that causes the immediate interruption of the manoeuvre (with a short reverse run). Devices with output featuring normally open "NO" contacts (like the KS1 selector switch) and devices with normally closed "NC" contacts, as well as devices with 8.2K constant resistance output, like sensitive edges, can be connected to this input. Multiple devices, even of different type, can be connected to the STOP input if suitable arrangements are made. To do this, proceed as described in the following table:

Table 10 NO In parallel

(note 2) e NO p y t e c v e d i NC

(note 1) d n 2 8,2k In parallel 1st device type:

NC

(note 1) In series

(note 3) In series 8,2k In parallel In series in parallel

(note 4) Note 1. The NO and NC combination can be obtained by placing the two contacts in parallel, and placing in series to the NC contact an 8.2K resistance (therefore, the combination of 3 devices is also possible: NO, NC and 8.2K). 20 WG20 Instructions 5.3.3 Recognition of Other Devices Normally the recognition of the devices connected to the ECSBus and the STOP input takes place during the installation stage. However, if new devices are added or old ones removed, the learning process can be gone through again by proceeding as follows:

1 On the control unit, press the P2 [B] button and hold it down for at least three seconds, then release it. 2 Wait a few seconds for the control unit to finish recognizing the devices. 3 When the recognition stage is completed the P2 LED [A] should go off. If the P2 LED flashes it means that something is wrong; see paragraph 5.5 "Troubleshooting". 5.3.4 Addition of Optional Photocells Additional photocells can be installed at any time on top of those supplied with WG20. In an automation system for 2-leaf gates these can be arranged as shown in Figure 64. 4 After you have added or removed any devices, the automation system must be tested again according to the directions contained in paragraph 3.7.1 "Testing". A B Figure 63 Table 11 Photocell Jumpers Photocell Jumpers Figure 64 A B C Photocell h=50cm;

activated when gate closes D Photocell h=100cm; activated when gate opens or closes Photocell h=100cm;

activated when gate closes E Photocell to the right activated when gate opens Photocell h=50cm;

activated when gate opens or closes F Photocell to the left activated when gate opens To ensure the correct recognition of the photocells by the control unit, the former must be assigned addresses by means of jumpers. The address allocation procedure must be performed on TX as well as RX (arranging the jumpers in the same manner), but you must make sure that there are no other pairs of photocells having the same address. The photocells need to be assigned addresses to make sure that they are correctly recognized among the other ECSBus devices, and in order to assign the performed function. 1 Open the shell of the photocell. 2 Identify the position where they are installed based on figure 64 and connect with jumper according to Table 11. The unused jumpers must be stored in their proper compartment for future use (Figure 65). 3 Perform the recognition stage as explained in paragraph 5.3.3

"Recognition of other devices". Figure 65 WG20 Instructions 21 5.4 Memorization of Radio Transmitters The CL20 control unit contains a radio receiver for TX4 transmitters;

those included in the package are pre-memorized and operative. If you wish to memorize a new radio transmitter you have two choices:

Mode 1: in this "mode" the radio transmitter is used to its fullest extent, i.e. all the buttons execute a pre-established command (the transmitters supplied with WG20 are memorized in Mode 1). It is obvious that in Mode 1 a radio transmitter can be used to command a single automation, i.e.:

T1 button T2 button T3 button T4 button

"OPEN" command

"Pedestrian gate" command

"Open only" command

"Close only" command Mode 2: one of the four commands available can be associated to each button. This mode, used properly, allows you to command 2 or more different automations; for example:

5.4.1 Memorization Mode 1 1 Press button P1 [B] for at least 3 s.. When the P1 LED [A] goes off, release the button. 2 Within 10s, press any button on the radio transmitter to be memorized and hold it down for at least 3s. If the memorization procedure is successful, the "P1" LED will flash 3 times. 3 If there are other transmitters to be memorized, repeat step 2 within the next 10s, otherwise the memorization stage will terminate automatically. 5.4.2 Memorization Mode 2 With the memorization in mode 2 of the radio transmitter, any one of the four commands ("OPEN", "Open partially", "Open only" and "Close only") can be associated to each button. In Mode 2 each button requires a separate memorization stage. 1 Delete the remote control system by following procedure "5.4.4 Deleting a radio transmitter."

2 Press button P1 (figure 66) on the control unit as many times as the number corresponding to the desired command, according to the following table: (e.g. 3 times for the "Open only" command). 1 time 2 times 3 times 4 times

"OPEN" command

"Pedestrian gate" command

"Open only" command

"Close only" command 5.4.3 "Remote" Memorization A new radio transmitter can be memorized in the control unit without directly operating the buttons on it. You need to have an "OLD" pre-

memorized operational radio transmitter. The "NEW" radio transmitter to be memorized will inherit the characteristics of the OLD one, i.e. if the OLD radio transmitter was memorized in Mode 1, the NEW one will also be memorized in Mode 1. In this case, during the memorization stage you can press any key on the two transmitters. If, on the other hand, the OLD transmitter was memorized in Mode 2 you must press the button on the OLD transmitter which corresponds to the desired command, and the button on the NEW transmitter to which you wish to associate that command. Holding the two transmitters, position yourself within the operating range of the automation and perform the following operations:

22 WG20 Instructions T1 button

"Open only" command Tasto T2 Tasto T3 Tasto T4

"Close only" command

"OPEN" command

"OPEN" command Each transmitter is, of course, a separate unit, and while some are memorized in mode 1 others can be memorized in mode 2 on the control unit. The overall memory capacity is 150 units; memorization in mode 1 takes up one unit for each transmitter while mode 2 takes up one unit for each button. Warning: since the memorization procedures are timed (10s), you must read the instructions in the following paragraph before you proceed with their execution. A B Figure 66 3 Make sure that the P1 LED makes as many quick flashes as the number corresponding to the selected command. 4 Within 10 s, press the desired button on the radio transmitter to be memorized, and hold it down for at least 2 s. If the memorization procedure is successful, the "P1" LED will flash 3 times slowly. 5 If there are other transmitters to be memorized for the same type of command, repeat step 3 within the next 10s, otherwise the memorization stage will terminate automatically. 1 Press the button on the NEW radio transmitter and hold it down for at least 5s, then release it. 2 Press the button on the OLD radio transmitter 3 times slowly. 3 Press the button on the NEW radio transmitter once slowly. At this point the NEW radio transmitter will be recognized by the control unit and will assume the characteristics of the OLD one. If there are other transmitters to be memorized, repeat all the steps above for each new transmitter. 5.4.4 Deleting a Radio Transmitter If a radio transmitter is available, this operation allows you to delete it. If the transmitter is memorized in Mode 1, a single deletion stage is sufficient: just press any button at point 3. If the transmitter is memorized in Mode 2, one deletion stage is needed for each memorized button. 1 Press and hold down button P1 [B] (Figure 67) on the control unit. 2 Wait until the P1 LED [A] lights up, then, within three seconds:

3 Press and hold down for at least three seconds the button of the radio transmitter to be deleted.If the radio transmitter has been deleted, the P1 LED will flash quickly five times. If the LED flashes slowly just once, it means that the deletion has not taken place because the transmitter is not memorized 4 If there are more transmitters to be deleted, repeat step 3 within ten seconds while pressing button P1, otherwise the deletion stage will terminate automatically. 5.4.5 Deleting all the Radio Transmitters With this operation all the memorized transmitters are deleted. 1 Press the P1 button [B] on the control unit and hold it down. 2 Wait until the P1 LED [A] lights up, then wait until it goes off, than wait until it has flashed 3 times. 3 Release the P1 button precisely upon the third flash. 4 Wait approximately 4s for the deletion process to be completed; during this time the LED will flash very quickly. If the procedure is successful, after a few moments the "P1" LED will flash slowly 5 times. 5.5 Troubleshooting A B Figure 67 The following table contains instructions to help you solve malfunctions or errors that may occur during the installation stage or in case of failure. Table 12 Symptoms The radio transmitter does not emit any signal (the LED [A] does not light up) The manoeuvre does not start and the

"ECSBbus" LED [B] does not flash The manoeuvre does not start and the flashing light is off The manoeuvre does not start and the flashing light flashes a few times Probable cause and possible solution Check to see if the batteries are exhausted, if necessary replace them (page 34) Make sure that the power cord is properly plugged into the mains outlet Check to see if the fuses [E] or [F] are blown; if necessary, identify the reason for the failure and then replace the fuses with others having the same current rating and characteristics.. Make sure that the command is actually received. If the command reaches the OPEN input, the corresponding "OPEN" LED [D] must light up; if you are using the radio transmitter, the "ECSBus" LED must make two long flashes. Make sure that the STOP input is active, i.e. that the "STOP" LED [C] comes on. If this does not happen, check the devices connected to the STOP input. The photocell test which is performed at the starting of each manoeuvre is not successful; check the photocells, also according to Table 13 on page 24. The manoeuvre starts but it is immediately followed by a reverse run The selected force is too low to move the leaves. Check to see whether there are any obstacles; if necessary increase the force as described on page 19. The manoeuvre is carried out but the flashing light does not work Make sure that there is voltage on the flashing light's FLASH terminal during the manoeuvre (being intermittent, the voltage value is not important: approximately 10-30Vac); if there is voltage, the problem is due to the lamp; in this case replace the lamp with one having the same characteristics. B C D A E F Figure 68 WG20 Instructions 23 5.6 Diagnostics and Signals A few devices issue special signals that allow you to recognize the operating status or possible malfunctions. 5.6.1 Photocells The photocells are equipped with a "SAFE" LED [A] that allows you to check the operating status at any time. Table 13

"SAFE" LED Off Status The photocell is not powered or is faulty Action Make sure that there is voltage (approx. 8-12 Vdc) on the photocell's terminals; if the voltage is correct, the photocell is probably faulty. 3 quick second's pause flashes and a Device not recognized by the control unit Repeat the recognition procedure on the control unit. Make sure that all the photocell pairs on ECSBus have different addresses (see Table 11 on page 21) 1 very slow flash The RX receives a perfect signal Normal operation 1 slow flash The RX receives a fair signal Normal operation 1 quick flash The RX receives a poor signal Normal operation but you should check the TX-RX alignment and make sure the glasses are clean 1 very quick flash The RX receives a very poor signal It is at the limit of normal operation, you should check the TX-RX alignment and make sure the glasses are clean Always on The RX does not receive any signal Check to see if there is an obstacle between TX and RX. Make sure that the LED on TX flashes once slowly. Check the TX-RX alignment A 5.6.2 Flashing light Figure 69 During the manoeuvre the flashing light flashes once every second. When something is wrong the flashes are more frequent (half a second); the light flashes twice with a second's pause between flashes. Table 14 Quick flashes 1 flash 1 second's pause 1 flash 2 flash 1 second's pause 2 flashes 3 flash 1 second's pause 3 flashes 4 flash 1 second's pause 4 flashes 24 WG20 Instructions Status ECSBus error Triggering of a photocell Action At the staring of the manoeuvre, the devices present do not correspond to those recognized; check and if necessary try repeating the recognition process. (see 5.3.3 "Recognition of Other Devices"). One or more devices may be faulty; check and, if necessary, replace them. At the staring of the manoeuvre, one or more photocells do not enable it; check to see if there are any obstacles. If there is an obstacle impeding the movement no action is required. Cutting in of the "motor force" limiting device During the movement, the leaf experienced excessive friction;

Name Date Signature Location 7.3 Annexe 3: Operating Guide This guide should be stored in an accessible location and made available to all users of the automation. 7.3.1 Safety regulations Keep at a safe distance while the gate is moving; do not pass through until the gate has opened all the way and the leaves have stopped moving. Do not allow children to play near the gate or with its controls. Stop using the automation system immediately if you notice anything abnormal (strange noise or jerky movements); failure to observe this warning may result in serious danger and accidents. Do not touch any components while they are moving. Have periodic checks made according to the instructions provided in the maintenance schedule. Maintenance operations and repairs can only be performed by qualified technicians. 7.3.2 Gate Control With radio transmitter Control with safety devices out of order The radio transmitter is ready for use and the four buttons have the following functions:

If the safety devices are out of order or malfunctioning, it is still possible to control the gate. T1 T2 T3 T4 Figure 71 FUNCTION (*) T1 button T2 button T3 button T4 button

(*) This table must be prepared by the person who has programmed the system:

With selector switch The selector switch has two positions, with automatic return to the centre. ACTION Figure 72 FUNCTION Rotated to the right: "OPEN"

(*) Rotated to the left: "STOP"

It stops the movement of the gate

(*) This item must be drafted by the person who has programmed the system:. 1 Operate the gate control device (remote control or key-operated selector switch). If the safety devices enable the operation, the gate will open normally, otherwise:

2 The flashing light flashes a few times but the manoeuvre does not start

(the number of flashes depends on the reason why the manoeuvre is not enabled). 3 In this case, actuate the control again within 3 seconds and keep it actuated. 4 After approximately 2s the gate will start moving in the "man present"

mode, i.e. so long as the control is maintained the gate will keep moving;

as soon as the control is released the gate will stop. If the safety devices are out of order the automation must be repaired as soon as possible. WG20 Instructions 33 Gearmotor release 2 Insert the key in the pin. The gearmotor is equipped with a mechanical system which allows the gate to be opened and closed manually (i.e. as if WG20 were not present). The manual operation must be resorted to in case o power failures or system malfunctions. If a power failure occurs, the buffer battery can be used (PR1 optional accessory). If there is a malfunction of the gearmotor it is still possible to try and release the motor in order to check whether the problem is connected with the release mechanism. 1 Turn the release mechanism cover clockwise until the hole matches the release pin. 3 Turn the key anti-clockwise. Figure 74 Figure 73 4 At this point, the gate leaf can be moved manually. Figure 75 5 To restore the functionality of the automation system, rotate the lever clockwise while simultaneously moving the leaf until it is caught by the mechanism. 6 Remove the key and close the cover by turning it anti-clockwise. 7.3.3 Maintenance Operations to Be Performed by the User The only maintenance operations that the user can and must perform periodically concern the cleaning of the photocell glasses and the removal of leaves and debris that may impede the automation. Disconnect the power supply to the automation before you proceed to remove leaves and debris, to prevent anyone from activating the gate. Use a slightly damp cloth (not wet) to clean the surface of the devices. Do not use any substances containing alcohol, benzene, diluents or other flammable substances. The use of these substances could damage the devices, start fires or generate electric shocks. 7.3.4 Replacing the Remote Control Battery If the range of the remote control is significantly diminished and the light emitted by the LED is feeble, the remote control battery is probably exhausted. The remote control houses to CR2016 type lithium batteries. To replace them proceed as follows:

1 Open the bottom by pulling it. Figure 77 3 Insert the new battery, observing the polarity (the "+" symbol towards the bottom ). 4 Close the bottom until it clicks. The batteries contain polluting substances: do not dispose of them together with other waste but use the methods established by local regulations. Figure 76 2 Insert a small pointed tool in the slit and prise the batteries out. 34 WG20 Instructions Mhouse Via Pezza Alta, 13 - Z.I.
