Troubleshooting FAQ
The display does not turn on.
Check the protection fuse on the circuit board.
Check that power supply voltage is present at
terminals 1 and 2 and has the correct value.
The outputs do not activate.
No output voltage.
Solenoid valve wiring cut-off.
Check the output voltage at terminals 27-29.
Check that the solenoid valves have been
mounted correctly (IN-OUT).
Check that the wiring between the control unit
and the solenoid valves, and between the
same, is not cut-off or damaged.
Differential pressure metering
is not correct.
Clogged air connections.
Damaged tubes.
Check that differential pressure is 0.00 kPa
when the tubes are disconnected. In this case,
check that the connection pipes between the
equipment and the filter are not obstructed or
damaged.
The cleaning cycle is not
performed.
The Start cycle threshold is set too high in
automatic mode.
The Remote input contact is open.
Check the Start cycle threshold.
Check the status of the Remote input contact.
Anomalies present of alarm thresholds set
have been exceeded.
Check the connection of the control unit with
the valve actuators chain.
Check the type of alarm with the indications
on page 19 and with the programming carried
out.
The alarms do not activate the
signalling devices.
Errors in the wiring.
No alarm devices power supply.
The alarm devices must be powered by
external voltage.
At rest, the alarm relays have closed contact,
which opens in the case of an event.
The post-cleaning starts
during a conventional cleaning
cycle.
Fan Threshold set too high.
The fan input contact has been opened
during the cycle.
Check the Fan OFF threshold for post-
cleaning.
Check the status of the fan input contact.
Post-cleaning does not start
when the normal cleaning
cycle ends.
Fan Threshold set too low.
No post-cleaning cycles have been
programmed.
The fan input contact is closed.
Check that with the fan off, the pressure
measured is lower than the Fan threshold for
post-cleaning.
Check that the number of post-cleaning cycles
is different to zero.
Check the status of the fan input contact, if in
Manual modes.
The economiser occasionally
resets or controls the solenoid
valves casually.
Check that there is no electro-magnetic
interference on the power supply line,
coming from motors, punching machines,
welders, plasma cutters, etc.
Install a suppressor filter on the control unit
power supply input.
Power the control unit with a separate line,
not deriving from that of the power line that
powers the machines.
With the fan off, the display
does not show 0.0 kPa.
Incorrect Zero dP calibration.
Calibrate the Zero dP appropriately or run the
self-calibration function, explained ion page
13.
