ENGLISH
Lifting station does not work and alarm is
triggered
• The thermostat in the motor windings has switched off the
system because the pump is obstructed. In this case, close
the inlet sluice valve, drain the tank, unplug the mains power
supply cable or switch off at the main switch, remove the
pump module, and clear the blockage
Decreased pumping performance
• Check that the sluice valve in the pressure pipe is fully open.
• If the pressure pipe is obstructed, flush water through the
pressure pipe to clear it.
• If the swing-type check valve is obstructed, close the sluice
valve and clean the swing-type check valve.
• If the ventilation system is blocked, clean the ventilation
hose between the pump and the tank and check the drilled
holes.
"Drehfeld falsch"
(Wrong rotating field) indicator
is lit
• Mains phase sequence is wrong or phase is absent - thus
lower or absent pump delivery. The mains connection must
be corrected by a qualified electrician only.
"P2, P3 Pump failure" indicator is lit.
• The pump is protected by an integrated overload safety
switch which turns the pump off if it overloads or if there
is an electrical motor fault. After this has been triggered,
it must be reset by hand in order to use the pump again.
The control unit must be opened by a qualified electrician in
order to press the safety switch reset button.
"P5 High water" indicator is lit
• Water level in the tank too high because of low pump flow
rate or excessive inflow. Remove any obstructions in the
pump or pressure pipe and/or eliminate the excessive in-
flow.
LED P1 on the analogue evaluator is
continuously lit
• There is a fault in the level detection. Call our Customer ser-
vice.
• There is no residual water in the tank. Fill the tank with a
small amount of water.
• Note: If the LED lights up after the pumping operation, this
is not a sign of a malfunction. The LED goes off once the
tank is filled again with a small amount of wastewater.
Pump "snores" and does not switch itself off
• The switch-off point of the lifting station is too low.
Unscrew the three fastening screws of the level detection at
the front of the collecting tank. By carefully rotating it in an
anti-clockwise direction the switch-off point can be set to a
higher level. Retighten the screws. When the switch-off level
is reached during pumping, this is shown by the middle LED P2
on the analogue evaluator going off (on the right-hand side of
the control unit).
NOTICE! It may also be necessary to re-adjust the switch-on
level (please refer to the section “Redefining the switch-on
level”).
