Festo P.BE-CPX-AX-EN en 1107f
Wire break (Open Loop) and short-circuit monitoring can be
activated by means of appropriate parameterisation
(see Tab. 5/10).
With the channel-specific parameters "Definition limit value"
(parameters 15 ... 22) you can define a limit value for each
channel. With the parameter "Limit value monitoring" (para-
meter 8) you can define whether a diagnostic message is to
be displayed when the limit value is exceeded or not reached.
Note
If you are using a different temperature sensor from the
Pt 100: Set the sensor used with the parameterisation.
Monitoring of the sensor temperature range functions
correctly as follows:
2)
Set limit value
is not reached
No message
Diagnostic message
error no. 9
No message
2)
Set limit value
is exceeded
No message
No message
Diagnostic message
error no. 10
Sensor
temperature range
No message
Diagnostic message
If limit value is not
reached 9
If limit value is
exceeded 10
