Setup
Warning!
Ì Pay attention to the notes on commissioning and on the teach-in process in
the operating instructions for the safety switch used.
Ì In case of devices with teach-in input, ensure the circuit is correct.
Proceed as follows:
1. Ensure nobody can be placed in danger during setup.
2. Prior to setup, check whether all connections are correct (jumpers connected,
external circuit correct) and the AR switch chain is fitted with a bridging plug.
3. Close all safety guards and make sure that the feedback loop on the evaluation
unit is closed.
4. Switch on the power supply.
¨ The switches in the chain are initialized on starting. Unicode switches that have
not yet taught-in an actuator on starting, automatically teach-in the actuator.
This process can take up to one minute.
¨ If the AR evaluation unit is set up for automatic start, the OUT LED flashes and
signals that the self-test is being performed. After the self-test, the OUT and
STATE LEDs are continuously lit.
or
¨ If you start the AR evaluation unit manually, the STATE LED flashes and signals
that the self-test is being carried out. After the self-test, the STATE LED illumi-
nates continuously. The OUT LED flashes, since no start command has been
issued yet.
5. Press the start button (only necessary for manual start).
6. Then press the RST button on the AR evaluation unit for approx. 3 s to re-start
the device.
7. Check the correct function of the safety circuits connected. In case of problems,
see section Troubleshooting.
Important!
Use the status table in the section Troubleshooting to check the overall function.
In addition, the status LEDs on the respective safety switches provide information
about the status of the respective switch.
