The application and functionality of the WAL R1 module is the same for each KEBA product. It is used for wireless operation area monitoring. The manual is geared towards those who are using or intend to deploy an KEBA product with the work area limitation WAL module. Only electrical technicians who are qualified to the VDE 1000-10 standard are permitted to install and maintain it. This means personnel who:
can evaluate the work to be carried out and recognise the possible hazards based on their technical training, knowledge and experience plus their expertise in the applicable standards. have a level of knowledge equivalent to that obtained through professional training as a result of several years experience working in a similar field. 1.3 Intended use The intended use of the WAL module includes deployment in KEBA products. The WAL module (Work Area Limitation) is used to limit the area in which a wireless handheld terminal can be used. Therefore it has to be used in conjunction with a base station (e.g. CB4xx) which includes the counterpart WAL module. The WAL module may not be used to fulfil protection requirements in the area of personal safety to prevent a malfunction compromising personal safety.

!!! WAL - Work Area Limitation Module Product overview 3 Product overview 3.1 Summary The functionality of the WAL R1 module is described by using the imple-
mentation in the KeTop Safe Wireless System (KeTop T15x WL + CB4xx) as an example. Both components contain the same WAL module and show how it can be utilized:
To ensure that no dangerous actions of the machine or of machine parts can be triggered outside of the visible area of the hazardous area, there is an option for restricting the effective range when using a WAL R1 module. The effective range restriction also offers the advantage of reducing the probability of connection interruptions. Various tactile and optical measures (e.g. vibration in the handheld device, pulsation of the illuminated emergency stop) let the user know when the limit of the effective range has been reached. Depending on the direction, the frequency of these measures increases or slows down. If the user exits the effective range, the frequency increases. If the user moves into the ef-
fective range, the frequency is reduced. The maximum permissible effective range is 20 m and can be configured on the base station (CB4xx containing WAL R1 module) using DIP switch-
es. Zones of effective range restriction 1 ... Effective range of action 3 ... Area of infringement 2 ... Tolerance range Product overview The solid green line represents the working area that is configured as the effective range. The furthermost point in the working range defines the ef-
fective range of action (comparable to the cable length for corded devices). The yellow line represents the tolerance range. The radius is 5 m by default and cannot be configured. Even in the tolerance range, it must be possible to see into the hazard areas. 3.1.1 Effective range of action In the effective range, the full range of functions is ensured when there is a connection. For the handheld device (KeTop T15x WL) this means that the emergency stop is illuminated and functional and the enabling switch is al-
so functional. 3.1.2 Tolerance range When someone enters the tolerance range, this is indicated by vibrations in the handheld device and optical signals. The emergency stop is no longer continuously illuminated, but rather the light pulsates. The emergency stop is still functional, however. When the enabling switch is pressed, the output is deactivated after ap-
prox. 10 sec. The effective range is the only area where enabling can be ensured by releasing the enabling switch and pressing it again. An enable button that has not been actuated cannot be activated. 3.1.3 Area of infringement When someone enters the infringement area (i.e. exits the tolerance range), this is indicated right away by strong vibrations and optical signals of the handheld device (KeTop T15x WL). The emergency stop function is triggered after 1 sec and the illumination of the emergency stop is deac-
tivated on the handheld device. The machine enters a safe state. If the enabling switch is pressed, this is deactivated immediately when someone enters the infringement area. An enabling switch that has no been actuated can no longer be activated.

Suitable precautions must be taken to prevent any cables located behind the antenna from causing antenna detuning, e.g. providing a cover. 4.1 MIC requirements (Japan) In order to comply with MIC RF Exposure requirements, this device must be installed to provide at least 5 mm separation from the human body at all times.

Safety extra-low voltage The module is powered by safety extra-low voltage. Radiated power The EIRP value of the WAL R1 module is -1.21 dBm at maximum and therefore far below the applicable limit. The immunity of an electrical system depends essentially on wiring and shielding that is designed to overcome any EMC problems. Servicing experience has shown that inadequate wiring and shielding is a common cause of system interference and failure. Electromagnetic interference is far more troublesome than "conventional"
faults:
It is not normally recognised as such from the symptoms displayed and can often be mistaken for a fault in an assembly, which is basically sound. They mainly occur sporadically and are difficult to duplicate. As a consequence fault-finding is time-consuming and expensive. Therefore ensure from the start that the wiring and shielding conforms to the guidelines documented below. 5.1.3 Which EMC measures must be taken?
The EMC measures for the WAL module concentrate on shielding the connecting cable of the module. 5.2 Power supply The power to the WAL R1 module is supplied via the connectors for communication (3.3V or 5V). The high-frequency area (U2, U10: AT86RF215) generates the voltages it uses by itself. Connections and wiring 5.3 Module interfaces 5.3.1 Assembly Side A:

This 5-pin connector can be populated for USB communication and debug purposed. It is possible to use 5V from the USB cable as power supply. WAL R1 does currently not use this possibility. The necessary components are not populated on WAL R1. 5.3.4 Connector Debug 5.3.5 microSD Slot 5.3.6 Antenna connections These connectors are just used for debug purposed and serve no purpose in normal operation. The microSD slot is just used for debug purposes and serves no purpose in normal operation. Using these coaxial connectors the external dipol antennas can be con-
nected. Two connectors each build a pair for one antenna to connect:
S5+S6 and S7+S8. It is not allowed to mix these connections for one an-
tenna. Only the usage of an antenna mentioned in chapter 8 (Accessories and spares) is allowed and certified. 5.3.7 Status LEDs The functionality of the three status LEDs is explained in chapter 6 (Status LEDs) Connections and wiring 5.4 Cables 5.4.1 Connector cable for serial communication (Connector A, S1) The connection cable for the WAL R1 module to a baseboard for serial communication must be no longer than 10 cm. It does not have to be shielded. 5.4.2 Connector cable to the antennas (S5 S8) Only the connection cable included with the antenna listed in chapter 8
(Accessories and spares) is allowed and certified. Modifications of this 20 cm long cable are not permitted. One antenna is connected to S5 and S6 and the second antenna to S7 and S8. Intermixing of these connections between the antennas is not allowed.

Only KEBA technicians may repair faulty devices, otherwise the warranty becomes void. 7.2.1 Packaging and shipping The module is placed in protective packing for shipping. Please return the packaging since KEBA tries to reuse it to minimise the environmental impact. This protective packaging is not transport packaging and as such it is unsuitable for transport by carrier or air. Suitable, extra transport packaging must be used for this purpose. 7.3 Waste disposal Comply with your national regulations for the disposal of electronic components!
