7. Pressure sensor module CPX-4AE-P
7.5.1 Error messages of the pressure sensor module CPX-4AE-P
Error Description
number
9 Limit value underrun
10 Limit value overrun
27 Incorrect device type fitted
29 Parameterisation error
An error has occurred in the setting of a
parameter (monitored parameters:
see Tab. 7/3).
51 Sensor limit diagnostics
Physical limit value of a sensor has been
exceeded
– Process value invalid (see error
number 55) The output measured value
no longer corresponds to the physical
pressure present
– Hardware damage is possible
55 Invalid process value
Creation of the process value is not valid:
e.g. during the differential pressure
calculation (see Tab. 7/5), if the sensor
limit diagnostics are signaled for one of
the pressure sensors.
1)
The module will register the appropriate error depending on the parameterisation.
However, the input signals will be processed further.
2)
The (faulty) parameters entered will be ignored; the module operates with the last valid
parameters.

7-24
The pressure sensor module CPX-4AE-P can notify the
following errors:
1)
2)
Error handling
•
Check compressed air supply
•
Check the parameterisation
(see Tab. 7/9 and Tab. 7/10)
•
Undertake planned remedy
•
Servicing required
•
Check the parameterisation made and if
necessary make the parameterisation
again with the correct parameters
(valid parameters see Tab. 7/2)
•
Ensure that the maximum permitted
pressure is not exceeded
•
Check module for damage; replace if
necessary
•
