Installing and connecting the device
3.3 Connecting the device
Perform self-test
As soon as power is connected with the connecting cable, the HMI device runs a self-test
program once and automatically. All LEDs on the HMI device are switched on briefly during
program execution. This allows the user to check whether the LEDs are functioning correctly.
At the end of the self-test, the LEDs indicate the operating state of the device.
If the self-test reports an error, the "SF" LED lights up in red.
1. Repeat the switch-on operation.
2. If the LED does not go out, check the voltage in the power supply line to the
connection box.
3. If the LED still does not go out, send the device for repair.
Remove connector
You can remove the connecting cable at the connection box and/or at the device:
1. Lift up the connecting cable locking clip at the device.
2. To disconnect the connecting cable from the device, pull firmly on the connecting
cable connector.
3. Lift up the connecting cable locking clip at the connection box.
4. To remove the connecting cable from the connection box, pull hard on the connecting
cable connector.
If you do not intend to use the device with another connection box, place the device securely
in its wall-mounting bracket.
