4.11.8 Channel Diagnosis
Alarm type
Cause / solution
Invalid
Check the module configuration and parameterization
No_Output
Operating voltage too low ->
check the power
Over_Range
Sensor shows a higher value than the rated range
> check the output process
value
Under_Range
Sensor shows a lower value than the rated range
> check the output process
value
Short_Loop
The connection between the sensor and module shows a value that indicates a
short-circuit > check the sensor and cable connection between the sensor
and module
Open_Loop
The connection between the sensor and module shows a value that indicates an
interruption (open loop) > check the sensor and cable connection between
the module and field device
Unreliable
The operating voltage ACDC 24 V is below a specific value (AC or DC) > check the
operating voltage value (power supply)
Current output
(4 mA...20 mA)
