Error Possible cause Solution
• Problem with (PS) cable
• DIR_time settings If the unit does not go into Idling mode and filter clean-
ing does not take place after 10 seconds, break the PS
cable manually by opening fuse holder F4. Wait at least
10 seconds. If switching to Idling mode occurs this time,
troubleshoot the PS cable. If switching does not occur,
check the time set on the display (DIR_time function).
The compressed air pressure or
flow is too low.
• Adjust the pressure.
• Check the hose dimension
The solenoid valve is not connec-
ted properly.
Check the valve and air pressure.
The air lines, valve and/or cylinder
are blocked.
• Clean or replace the air lines, valve and/or cylinder.
• Filter incoming compressed air.
The cylinder and/or valve does
not work.
Replace the cylinder and/or valve.
Dust is hard to clean, normal
cleaning does not work.
Contact your nearest authorized distributor or Nederman
for technical advice.
Filter cleaning does
not work.
The cleaning interval is too short. Extend the cleaning interval.
Compressed air, (Pr/t)
is <1 bar.
See Section 3.3 Technical data . Too low compressed air
pressure can result in premature filter clogging. If the pres-
sure is lacking or too low, the piston cannot open the FCV
and lid properly. This results in insufficient cleaning and
premature filter clogging.
The CAS is connected to terminals X1:15 and X1:16. If no
CAS is installed, a jumper is linking the terminals to ensure
that the CAS message is not displayed in PLC Logo!.
Filter cleaning does not work. See Chapter 6 Maintenance . No dust is collected in
the collector bin.
Insignificant flow to the unit. See ‘Low vacuum or air flow’.
