sensor
In menu "System / Deactivate fault monitoring of pressure sensor", the fault
monitoring for the external nominal pressure sensor can be deactivated.
When delivered, the fault monitoring of the external nominal pressure sensor is
deactivated on the CAN router/repeater. The fault monitoring is activated when the
sensor is connected for the first time.
If it is connected again after replacing the sensor, the monitoring is activated again
automatically. In this case, the fault monitoring must be deactivated again.

As of version 1.5 of the Trailer EBS E (production date from CW 49/2009), in the
diagnostic software "Trailer EBS E" with connected external pressure sensor on
the CAN router/-repeater, select setting: "Nominal pressure sensor on R/R" to
improve the communication between the devices.
