Technical Description
Note: The pump operation can be checked from the outside by
observing whether the stirring paddle is rotating (e.g. by trigge-
ring an additional lubrication), whether the LED on the printed
circuit board are lit or whether the external relay has picked up.
Cause:
Voltage supply interrupted
Voltage supply to the printed-circuit interrupted
Printed circuit board defective
Remedy:
Check the voltage supply to the pump. If necessary, correct
the cause of the fault.
Check the line leading from the pump plug to the printed cir-
cuit board.
If the voltage is applied, the left-hand LED is lit.
Replace the printed circuit board.
Fault: The pump motor does not run
Cause:
Piston detector (initiator) defective.
Cable connection of the piston detector to the pump interrup-
ted
Printed circuit board defective
Remedy:
Disconnect the main line leading to the monitored metering
device.
Unscrew the piston detector and check it. For this, insert a
metallic pin into the borehole of the detector. Let it there over
2 seconds and then remove it. If the pump is not switched off
afterwards, check the cable conections to the pump. If neces-
sary, replace the piston detector with the connector.
Check the cable connections to the pump. If necessary, repla-
ce the piston detector with the connector.
Replace the printed circuit board
Fault: The pump motor supplies permanently (5 minutes or 30 minutes )- Duration of the monitoring time
