Each system consists of a portable control SECTION 1 GENERAL INFORMATION 1.1 SCOPE This manual contains information necessary to install, operate and maintain Crane Boss Radio Remote Control Systems. The information is generally applicable to all Crane Boss systems manufactured by Robinson Engineering Company. Data which are unique to the particular system for which this manual is furnished are given in Section 4. 1.2 SYSTEM DESCRIPTION controls and accessories required for reliable electrical operation of a crane or other machinery from a portable wireless control transmitter. Control functions are provided to meet the particular requirements of each application. Characteristic features are:
transmitter which operates in conjunction with receiving equipment installed on the crane structure and electrically connected to the crane magnetic controllers. 2. "Fail-safe" circuits are used throughout the system. 3. The command link is capable of handling all motions simultaneously. 4. The system uses digital pulse code frequency modulation. It was developed specifically for industrial control. 1-1 5. The system utilizes fully solid state electronic circuits, with heavy duty relay contact output circuits. 6. Maintenance requirements are greatly reduced by modular design and use of digital switching circuits. The entire system includes only one field adjustable control, receiver sensitivity, which is non-critical. No special test equipment is required. 7. Radio control of several cranes in the same plant without interference is entirely practical. Each transmitter transmits a unique address code, which prevents response by other than the intended unit. In addition, the operating frequencies of different units are staggered within the frequency band to prevent interference. Proper selection of address codes and operating frequencies with respect to physical separation provides control of multiple installations with no practical limitation on the number at one location. 1-2 1.2.2 Transmitter - The transmitter is a portable unit which is carried by the operator. A shoulder harness and belt clips are provided to enable the operator to conveniently carry the unit while leaving hands free to operate controls. Switches on the transmitter control all functions as labelled. The portable transmitter weight is approximately 5.2 pounds. The transmitter includes integral antenna and battery pack. Battery is charged from standard a.c. wall outlet by means of a battery charger. Battery will provide 30 hours of continuous operation between charges. Full charging requires 10 to 12 hours. A transmitter with one battery pack can be operated continuously 16 hours per day and recharged in 6 hours. Continuous "around the clock"
operation can be accomplished by use of a spare battery pack, with one pack in use while the other is charging. 1.2.3 Receiving Equipment - The receiving equipment cabinet is mounted on the machinery and contains the radio receiving unit, decoding equipment and relays to convert the radio signal from the transmitter to signals suitable for operation of (magnetic) controls' contractors. 1-3 1.3 GUARANTEE Manufacturer warrants the delivered remote control system to be free of defective material and workmanship and agrees to remedy any such defect within two years of first party purchase at no charge to the purchaser upon return of defective parts to factory. Defects cause by improper installation, maintenance, misuse, tampering, neglect, accident, or use in violation of manufacturer's written instructions shall not be covered by this warranty. Manufacturer guarantees that remote control system will perform as outlined in this manual. Transferring of this warranty is acceptable and recommended. Please notify this factory of any and all transfers. 1-4 FCC Statement 1.4 FCC ID: NQHCBNT900TRX This equipment complies with Part 15 of the FCC rules, any changes or modifications not expressly approved by the manufacturer could void the users authority to operate the equipment. This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
* Reorient or relocate the receiving antenna.
* Increase the separation between the equipment and receiver.
* Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
* Consult the dealer or an experienced radio/TV technician for help. In order to maintain compliance with FCC regulations, shielded cables must be used with this equipment. Operation with non-approved equipment or unshielded cables is likely to result in interference to radio and TV reception. The user is cautioned that changes and modifications made to the equipment without the approval of manufacturer could void the user's authority to operate this equipment. 1.5 IC Statement IC: 4527A-CBNT900TRX This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions:
(1)this device may not cause interference, and (2)this device must accept any interference, including interference that may cause undesired operation of the device. 1-5 SECTION 2 OPERATION 2.1 RECEIVING EQUIPMENT Normal operating procedure is to leave receiving equipment energized at all times. (Power switch "On", neon indicator lighted). The unit can then be readily placed in operation by means of the portable control transmitter. 2.2 TRANSMITTER The transmitter should be stored in an assigned location when not being used to operate the crane. During idle periods, the "ON-OFF" switch should be in the "OFF" position and the battery charging cord connected. The battery cannot be damaged by prolonged charging; maintaining full charge will result in longer battery life. Battery capacity will allow 30 hours of continuous operation without recharging. Full recharge can be accomplished in 10 to 12 hours. 2.3 OPERATING PROCEDURE To place the unit in operation, proceed as follows:
1. Disconnect battery charging cord. Main switch
"OFF". 3. Operator should position himself so as to have a clear view of the motions and actions. 4. If multi-crane unit is being used, make certain proper selection is made. 5. With all operating controls in neutral position, turn Master Switch and Key Switch "ON". 2-1 6. Wait at least three seconds, then depress "Enable"
or "Reset" bar. Master Relay and Mainline Contactor on Crane are energized. Master indicating light on crane, if provided, will light. 7. Crane can now be moved by operating desired control levers. The direction and speed of motion will be determined by direction and distance control levers are deflected. All motion controls are spring loaded to neutral so that "hands off"
condition will stop the crane. 8. In the event of an emergency situation, immediately place master switch in "OFF" position. This will de-energize crane main contactor. 9. Upon completion of lift, restore crane to proper parking position and turn Master switch and Key switch "OFF". Remove key from switch. Replace transmitter in designated storage location, connect battery charging cord and check that both lights on charger are on. 10. The "POWER" indicator on the charging unit indicates that power is being supplied to the charger. The "CHARGE" light indicates flow of charging current to the battery. (Trickle-charge of a "full" battery means the light will be on as long as a battery is connected.) 11. The rechargeable battery pack is removable from the transmitter, and may be charged while either installed on the transmitter or removed from the transmitter. For applications which require continuous "around the clock" operation, one battery pack can be in use while a second is on charge, and the two battery packs interchanged daily. 2-2 2.4 MISCELLANEOUS OPERATING INFORMATION Abnormal electrical conditions during operation will de-energize control circuits, stopping motion. This can be caused by any one of a number of abnormal conditions. Among these are:
1. Weak or improper radio signal. 2. Interruption of power to receiving equipment. 3. Radio interference. 4. Malfunction of radio equipment. 5. Malfunction of crane electrical equipment. If the abnormal condition is temporary, control can be resumed by repeating steps 1. through 6. of paragraph 2.3. The exact sequence of operation must be followed to accomplish operation of safety circuits in the receiving equipment. 2-3 SECTION 3 PRINCIPLE OF OPERATION 3.1 TRANSMITTER The Transmitter is a battery operated frequency modulation radio transmitter. Incorporated with the transmitter is an antenna and rechargeable battery pack. Transmitter carrier frequency is crystal controlled. When the various switches are actuated, coded control signals are sent to the receiving equipment via the antenna. A block diagram of the transmitter is shown by Fig. 3-1. The radio frequency signal radiated by the antenna is generated by the RF Assembly, and is frequency modulated by a pulse code modulation signal. This modulation signal is generated by the Coder Assembly and consists of a series of synchronizing pulses determined by the position of the various function controls, which are actuated by the operator. Coder Assemblies used in all transmitters are identical in function and are interchangeable. Variation in code format between systems is accomplished by means of factory connections on the Junction Board, by the Address Plug, and by wiring to the various control devices. All RF Boards for the same frequency band are identical and interchangeable except for the frequency. In multiple system installations where control functions of the various cranes are similar, a given transmitter may be converted from control of one crane to another by changing the Crane Address Plug installed in the transmitter. The Receivers used in multiple crane installations are normally supplied with capability of receiving all transmitting frequencies used at that installation. 3-1 Figure 3-1: Block Diagram, Transmitter 3-2 3.2 RECEIVING EQUIPMENT A block diagram is shown by Figure 3-2. The radio signal from the transmitter is received by the antenna, which is connected to the Receiver by coaxial cable. Receiver data output is fed to the Decoder, where it is decoded and signals suitable for operation of the output relays are generated. The output relays provide heavy duty control circuits to the basic machine electrical controllers. 3.2.1 Antenna - The Antenna is pre-tuned for the frequency band used. 3.2.2 Receiver - The Receiver amplifies and detects the frequency modulated pulse code signal and includes filtering and shaping circuits to process the signal. Data output consists of rectangular pulses of 12 volts amplitude which are a replica of the transmitter coder output. The Receiver is a synthesized frequency controlled scanning type receiver which continuously scans all selected channels until a signal is received which contains the proper address code. When proper address code is received, scanning stops and, the receiver remains "locked-on" that channel for as long as the code remains. Channels can be turned Off or locked-out when unused or turned On when other equipment is added. A VOLUME control is provided to permit audio monitoring, via internal loudspeaker, of the received signal for test and maintenance purposes. This control has no effect on the control function of the system and should be left in the full (CCW) off position during normal operation. 3-3 3.2.3 Decoder - The receiver data output is connected to the Decoder through the Controller, where it is processed into form suitable for operation of the Relays. The Decoder also performs certain synchronization, safety interlock, digital filtering and noise rejection functions. All DC voltages originate in the Decoder. 3.2.4 Address Code - The address is a two digit hexadecimal number that is set at the factory. The number for each system is shown in the "Code" number block in the lower right corner of the Controller. 3.2.5 Output Relays - Relay contact logic circuits provide additional safety sequencing and interlocking functions. Output circuits are connected to terminal blocks for connection to magnetic controllers. Output relay circuits are rated for operation of up to NEMA size 4 contactors at a maximum coil voltage of 125 volts a.c. 3.2.6 Transfer Switch - Wiring as shown on the Interconnection Diagram allows only a mutually exclusive transfer between modes of operation. (If a back-up mode exists.) 3-4 3-5 3.3 DIGITAL CODE FORMAT The digital control code, which is transmitted by frequency modulation of the transmitter, consists of a series of pulses which is repeated at a rate of 25 per second (40 milliseconds period). Each series consists of a synchronizing pulse of 4 milliseconds duration, followed by 90 spaces of 400 microseconds duration each. Each of these 90 spaces may or may not be occupied by a control pulse, depending on the control signal. Control pulses are 200 microseconds between adjacent control pulses. For the purpose of defining the code signal, the 90 spaces are divided into nine blocks of ten spaces each. These nine blocks are identified as Block 0 through Block 8. The ten pulse spaces of each block are identified by the numerals 0 through 9. In general, one ten bit block is assigned for a particular function such as Address, Bridge, Trolley, Hoist, etc. 3.3.1 Pulse space assignments within a block for the major motions, Bridge, Trolley(s), Hoist(s), are standardized. For each function, pulses occupy the space listed.

The Address Code and Enable codes for this unit are:
Address: 0, 2, 3, 4 (HEX 82) Enable: 0, 1, 2, 3, 4 4-2 SECTION 5 MAINTENANCE The system is of modular design, with plug-in type electronic sub-assemblies and readily replaceable electrical components. Trouble can be corrected by locating and replacing the defective part, using the substitution method. It is suggested that spare parts be obtained for replacement purposes. Field repair of electronic sub-assemblies is not recommended. Improper techniques can result in damage to components and voiding of warranty. The factory will provide prompt test and repair or replacement of returned defective or questionable parts, including the complete transmitter, at nominal cost; or at no cost under warranty. Federal Communications Commission Rules and Regulations require that tuning adjustments on the radio frequency (RF) portion of the transmitter be made only by a properly licensed person. 5.1 PREVENTIVE MAINTENANCE No preventive maintenance is required except for periodic inspection for security of hardware, harnessed internal wiring and to check for intrusion of dirt or foreign matter. Relay contacts may be checked for excessive arcing by cycling through all motions. Replace parts as necessary. 5.2 CORRECTIVE MAINTENANCE 5.2.1 General - In case of suspected Radio Remote Control System trouble, activate the back-up controls and check for normal machine operation. If back-up system operation is not normal, locate and correct trouble in basic equipment before proceeding to radio equipment. 5-1 5.2.2 Transmitter - (See Block Diagram, Transmitter, Fig. 3-1, and Transmitter Components, Fig.5-1). 5.2.2.1 Replaceable Batteries* - Battery voltage may be measured at the LH terminals of the top two cells (top cell + , next cell -). If the voltage is less than 4.5 volts with transmitter on (Key Switch on, "Start/Reset, ON, Off" Toggle Switch ON) batteries should be replaced. 5.2.2.2 Transmitter Test - A simple qualitative check of transmitter operation may be made by monitoring the receiver. A normal signal will exhibit a characteristic 25 Hertz "motorboat" sound in the Receiver speaker due to the 25 Hz. pulse modulation. Failure to quiet receiver noise indicates no transmitter output. Receiver quieting, but without presence of modulation, indicates RF output, but defective transmitter coder. CAUTION: When the Master Relay (and Main Contactor) is energized, any energized motion relay will cause crane motion. 5.2.2.3 Multiple System Applications - A transmitter may be converted from operation of one unit to another by changing the Address Plug installed in the transmitter. The unit to be controlled must have the proper receiver frequency channel activated. Each transmitter frequency is marked on the frequency control crystal. Access to the interior of the transmitter is made by removing the two Phillips head screws retaining the aluminum back plate and removing the back. Internal arrangement of parts is shown by Figure 5-1. Address Plugs may be accessed by removing two nylon thumb nuts and the plug retainer. The electronics assembly, consisting of the Junction Board, Coder Assembly and RF Assembly, can be removed by releasing the two card guide locks and carefully sliding the assembly from the guides. The Coder and RF Assemblies are connected to the Junction Board electrically and mechanically by two connectors oriented perpendicular to the boards. They are further retained by the long 4-40 machine screws.
* Optional 5-2 5-3 CAUTION: In replacing the Electronics Assembly in the case, use care to lift the two antenna spring contacts over the case bottom on insertion to prevent damage to the contacts. 5.2.3 Receiving Equipment - The receiving equipment consists of a Receiver, a Controller, a Decoder and miscellaneous components (transformer, antenna, enclosure, etc.). 5.2.3.1 Receiver - The transmitter command signals transmitted to the Receiver are processed by the Receiver and are conducted to the Decoder via the Receiver Cable and the Controller board. The Decoder will return a command to the Receiver to lock onto a radio RF channel from which a valid address code has been received. This is squelch activated. 5.2.3.2 Decoder - The Decoder contains the DC power supplies and the logic processing circuits to convert the signals from the Receiver into output signals to drive the required relays. All of the relays on the Controller except the Master Relay are operated directly from the Controller. 5.2.3.3 Controller - The Controller contains the relays and terminal strips to provide isolation circuits to the Crane Controls. Each of the relays has an indicating light (LED and dropping resistor) parallel to its coil to provide an indication of the operation in progress. Side Board(s) - The Side Board contains the Relays and terminal strips to provide isolation circuits to the Hoist 2 and Trolley 2* Crane controls. Each of the relays has an indicating light (LED and dropping resistor) parallel to its coil to provide an indication of the operation in progress. WARNING: The set of DIP switches next to the Decoder connection are used to set the Receiving equipment Address at the factory. DO NOT attempt any alteration!
* Optional 5-4 The Controller board and Side Boards have printed traces of two widths - the wide traces are at crane control voltage (117 VAC) and most (but not all) are on the back of the board while the narrow traces (low voltage AC and DC) are on both sides of the boards. CAUTION: Keep fingers off of the back of the board!
CAUTION: Keep fingers off of the fuse!
CAUTION: Use extreme care when probing the board with voltmeter probes, etc.!
5-5 MAINTENANCE CHECKS CAUTION: MAKE CERTAIN THAT THE POWER SWITCH IS 'OFF' WHILE PLUGGING OR UNPLUGING, CONNECTING OR DISCONNECTING ANY COMPONENT. Non-observance may result in damage and void the warranty. CAUTION: When the Master Relay (and Main Contactor) is energized, any energized motion relay will cause crane motion. Refer to Block Diagram, Fig. 3-2 and Schematic, Controller, to assist in tracing trouble. 5.2.3.4 System Functional Test -

* Optional 5-6 If any relay and its LED indicator fails to operate, replace the Decoder. (See "CAUTION", top of Page 5-6). This test provides an opportunity to observe the relays operate mechanically and an opportunity to detect a defective relay. It may also be used as an aid in locating problems in the output circuits to the crane. NOTE: If step 1 does not provide any of the indications noted and all voltage checks of para. 5.2.3.5 are correct, replace the Address relay. (See "CAUTION", top of Page 5-6). 5-7 5-8 5.2.3.5 Voltage Checks:

(See "CAUTION", top of Page 5-6). 5-9 5.2.3.6 Receiver - use the Transmitter qualitative test, para. 5.2.2.2 to check the Receiver. If receiving range appears to be reduced, check antenna for defects and proper connections. Make certain that the "Squelch" is set at wide open, its max clockwise position, for maximum range. Note: The cable connecting the Receiver to the Controller should not be ignored. A continuity test may be appropriate.
(See "CAUTION", top of Page 5-6). 5.2.3.7 Decoder - The only check for a suspected defective Decoder is substitution of a spare module. 5-10 5.2.3.8 Controller - Refer to Schematic, Controller, for assistance in circuit tracing. CAUTION: When the Master (and Main Contactor) is energized, any energized motion relay will cause crane motion. With Transmitter "Off", all relays (and LEDs) should be de-energized. Main Circuit - This circuit is designed to operate in the following sequence:
1. Transmitter "Off", all relays de-energized. 2. Transmitter "On", Address relay energized. Enable Pushbutton depressed, Enable Relay energized. 3. Address and Enable relays energize Master Relay (M) if all Transmitter function controls are "Off". Address relay must be energized before any other function relay may be energized. 4. De-energizing the Address Relay by turning the Transmitter "Off" de-energizes the Main Contactor, Enable and Master relays. The Master Relay is controlled by relay contact circuits only. An examination of the Schematic will reveal a series of normally closed circuits. If any of these relays are energized, the circuit will open, not allowing the master relay to energize. This is also true of any of these relays are missing or have a defective contact. Also note, if the Address and Enable relays are not energized, the Master Relay cannot energize. Safety Circuit - This circuit is a comparison circuit between the Address relay and the Enable relay condition providing for a system shut down in the event of a mis-match of more than a fraction of a second duration. 5-11 Quantity Recommended System Spare Parts Spares 1 1 1 1 1 1 4-5 0-1 5.3 REPLACEABLE PARTS When purchasing parts from the factory, please provide the Serial Number of your equipment (See nameplate on Transmitter or Receiving Equipment).
