9.6.4 Troubleshooting
When you leave the commissioning menu, the universal controller checks whether
a sensor is connected to the LIM input.
Limit sensor
connected?
• If, at that time, a sensor is connected, but is missing later, a sensor error
message is delivered and presented on the display:
– "Xx ---" => sensor missing
– "Xx ooo" => short-circuit
• If, at that time, no sensor is connected, limitation will be deactivated
