Drive motor defective
If the motor does not run when the driving switch is
switched on or if the feed line to the motor is damaged, the signal
lamp flashes after 2 seconds as follows:
A
1 second -
”ON”
- 1 second -
”OFF”
Malfunctions
such as
- blocked lubrication point (s)
- blocked metering devices (s)
- interruption in the main line leading to the metering device
equipped with a proximity switch
- air in system
- reservoir empty
are indicated as described under B.
The above mentioned faults cause the pistons in the
monitored metering device to stop. The signal lamp
indicates the respective fault signal with the following flashing
frequencies:
Lubrication circuit 1 malfunctioning
B
0.5 second -
”ON”
- 1 second -
”OFF”
Low-level control
The signal lamp is flashing with the following
frequency:
Reservoir empty
E
0.5 second -
”ON”
- 0.5 second -
”OFF”
Fault Indication
Fig. 15 - Flashing frequencies in the case of malfunctions
A - Drive motor defective
B - Lubrication circuit 1 malfunctioning
E - In the case of low-level control: reservoir empty
F - Fault acknowledged (maintained lightening)
Note: The low-level signal is converted into a flashing
signal with the a.m. frequency only after 6 motor
revolutions.
• In the case of a malfunction the proximity switch (initiator) can
no longer record the piston movements and
therefore, 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”
