7. TROUBLESHOOTING
ALARM
Supply voltage alarm too high
Supply voltage alarm too low
Alarm P. INP CORTOC. 0V
Alarm P. OUT CORTOC. 0V
P. INP alarm DISCONNECTED
P. OUT alarm DISCONNECTED
PRESSURE OUT OF RANGE ALARM
POSSIBLE CAUSES
SOLUTION
Supply voltage higher 30 V
Increase to a sufficient voltage.
Supply voltage below 18 V
Supply solenoid valve has shortcircuited
Drain solenoid valve has shortcircuited
Switch the unit off and back on again. If the
Fill solenoid valve disconnected
alarm persists, contact the manufacturer.
Drain solenoid valve disconnected
Downstream pressure exceeds 10200 mbar
Check to see if the drain is blocked. The alarm resets
automatically when the pressure drops below the
threshold.
7.1 LIST OF ALLARMS
PROBLEM
The display does not come on
The unit does not respond or responds wrongly to the setpoint
The unit does not reach the desired pressure
The display shows an unreal value
The display is difficult to read
The unit adjusts continually
Other problems
POSSIBLE CAUSES
SOLUTION
No power supply IO-Link
Check the power supply, make sure it is
enough and check the wiring is in accordance
with the wiring diagram
Wrong input signal configuration
Configure the appropriate type of input from the menu
Check the signal wire is connected to the right
pin
Setpoint too low
Provide a suitable setpoint
The full-scale setting is at a lower pressure
Set the full scale correctly
than desired
The supply pressure is too low
Increase the supply pressure
Wrong unit of measurement
Check the unit of measurement
Poor contrast
Adjust the contrast
Air leak in the circuit after the unit
Eliminate the leak
Continuous variation in volume
Normal behaviour; the unit has to keep
adjusting the maintain the preset pressure
Deadband too small
Increase the deadband
Contact the manufacturer
