Errors and troubleshooting
Errors and troubleshooting
Error Cause(n) Remedy
No flow The pump is conveying in
the wrong direction
Check the rotational
direction of the motor
and, if necessary,
reverse the phases.
Shut-off device outside of
the CSM in the suction or
pressure line is closed.
Open all the locking
features in the suction
and pressure lines.
Suction strainer of the gear
pump is clogged.
Clean the suction
strainer. See page 42.
Only CSM-E 1xxx-1 / -2:
The coupling between the
motor and the pump is
loose or faulty.
Contact HYDAC.
Only CSM-E 1xxx-4:
The magnetic coupling is
disengaged and is slipping.
Loud noise emissions.
Switch the pump off.
Allow the unit to cool
down. Switch the unit on
again.
Contact HYDAC.
With highly viscous oil and
extremely high amounts of
air, an air bubble can get
stuck directly behind the
pump so that it does not
rise and flow out through
the conduit. The pump is
unable to pump against this
pressurized air.
Fully open the
downstream valve so
that this pressure can
drop and the pump can
transfer again.
No function Not connected to power
supply
Check the electrical
connection: plug, cable
and socket
If there are error messages from the sensors, please consult the
corresponding chapters in the operation and maintenance instructions of the
corresponding sensors.
Taking the unit out of operation
Drain the unit completely, including all of its components, before
decommissioning. Disconnect all electrical and hydraulic connections.
