WAL - Work Area Limitation Module Introduction 1 Introduction 1.1 Purpose of the document This manual describes the WAL module, which is already permanently installed in different KEBA products like the handheld terminal KeTop T15x Wireless and the corresponding CB4xx. The application and functionality of the WAL R1 module is the same for each KEBA product. It is used for wireless operation area monitoring. 1.

WAL - Work Area Limitation Module Introduction 1.4 Documentation for further reading The following is a listing of manuals for components, which are equipped with a WAL module: Doc. No.: Planning manual Description 2904965003 KeTop Safe Wireless System (T15xWL / CB4xx) – English Describes the installation, assembly, connection and operation of the safe wireless system.
Safety notes 2 Safety notes 2.1 Representation At various points in this manual you will see notes and precautionary warnings regarding possible hazards. The symbols used have the following meaning: ! DANGER! ! WARNING! ! CAUTION! • indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. • indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
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 implementation in the KeTop Safe Wireless System (KeTop T15x WL + CB4xx) as an example.
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 effective 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.

Assembly and installation notes 4 Assembly and installation notes To guarantee the specified antenna range the minimum clearance between antenna and base material (e.g. aluminium) must be respected. Suitable precautions must be taken to prevent any cables located behind the antenna from causing antenna detuning, e.g. providing a cover. 4.
WAL - Work Area Limitation Module Connections and wiring 5 Connections and wiring 5.1 EMC and wiring guidelines 5.1.1 Personal safety and exposure 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. 5.1.2 Why EMC-aware wiring? The immunity of an electrical system depends essentially on wiring and shielding that is designed to overcome any EMC problems.
Connections and wiring 5.3 Module interfaces 5.3.1 Assembly Side A: Side B: Connector B Connector A Connector Debug Connector Debug Status LEDs microSD slot Antenna connections Component No.
WAL - Work Area Limitation Module Connections and wiring 5.3.2 Connector A This 7-pin connector is used for serial communication (UART) and the 3.3V power supply. 5.3.3 Connector B 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.
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.
WAL - Work Area Limitation Module Status LEDs 6 Status LEDs 6.1 WAL R1 status LEDs The module contains three status LEDs (red, yellow and green) directly on the PCB located on side A between U1 and S3.
Maintenance and repair notes 7 Maintenance and repair notes 7.1 Maintenance This device does not require regular maintenance. 7.2 Repair 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.
