9.7.3 Troubleshooting
When you leave the commissioning menu, the universal controller checks whether
a sensor is connected.
Sensor connected?
• If, at that time, the sensor is connected, but is missing later, or if there is a short-
circuit in the cable, a sensor error message is delivered and presented on the
display:
– "Xx ---" => sensor missing
– "Xx ooo" => short-circuit
• If, at that time, the sensor is not connected, limitation will be deactivated
