The Faults and Their Causes

Drive motor defective
If the motor does not run when the driving switch or machine
contact is switched on or if the feed line to the motor is dama-
ged, the signal lamp flashes after 2 seconds as follows:
A
Malfunctions
such as
- blocked lubrication point (s)
- blocked metering devices (s)
- interruption in the main line leading to the metering device
equipped with a piston detector
- air in system
- reservoir empty (only if the pump is not equipped with a low-
level control)
are indicated as described under B, C or D.
The above mentioned faults cause the piston in the monitored
metering device to stop. The signal lamp indicates the respective
fault signals with the following flashing frequencies:
Lubrication circuit 1 malfunctioning
B
1053b95
Lubrication circuit 2 malfunctioning
C
Lubrication circuits 1 and 2 malfunctioning
D
Low-level control (option)
The signal lamp is flashing with the following frequency:
Reservoir empty
E
Note: The low-level signal is converted into a flashing signal of
the signal lamp only after 6 motor revolutions.
• In the case of a malfunction the piston detector (initiator) can
no longer record the piston movements and it cannot switch
off the pump.
• Due to the monitoring time which runs in parallel to the opera-
ting time, the printed circuit board switches off the pump at the
end of the monitoring time.
• A fault signal occurs.
• The signal lamp is flashing.
• The pump no longer starts automatically. See "To remedy to
a fault"
