Remedy:
* Remove main line towards the monitored divider valve.
* Unscrew and check piston detector by introducing a
iron
pin
into the borehole of the detector,
maintain it there for
more than 2 seconds and pull out again.
If then the
pump switches off, a blockage may exist; if the pump
does not switch off, check cable connections towards the
pump. If necessary, replace piston detector with connec-
ting plug.
* Check cable connections towards pump. If necessary,
replace piston detector with connecting plug.
* Exchange printed circuit board.
Troubleshooting
Pump 233
4209a99
The circulating segment in the display of the membrane
key pad indicates that the pump operates properly.
Fault: Pump motor does not run; stirring paddle does not turn
Cause:
Power supply interrupted. Segment display for On/h is
not lit.
*
Check the voltage supply to the pump/
fuses. If necessary, eliminate the fault or
replace the fuses.
*
Check the feed line from the fuses to the
plug of the pump and then to the printed
circuit board.
*
Trigger an additional lube cycle. Check
voltage supply from the p.c.b. to the motor, if
necessary replace motor.
* Replace p.c.b.
*

display is lit. Replace housing and
membrane key pad.
Remedy:
Power supply from printed circuit board to motor inter-
rupted. Electric motor defective.
Printed circuit board defective.
Key on membrane key pad defective.
Fault: Pump does not deliver lubricant
Cause:
Reservoir empty.
* LL *
display on the membrane key
pad is flashing.
Pump does not deliver lubricant and
*Er *
display on the
membrane key pad is flashing.
Air pockets in the lubricant.
Improper lubricant has been used.
Suction hole of pump element clogged.
Pump piston is worn.
Check valve in pump element defective or clogged.
Remedy:
* Fill up the reservoir with clean grease. Let the pump run
(trigger additional lube cycle) until the lubricant shows at
all lube points.
NOTE: Dependent on the ambient temperature and/ or type
of lubricant. the pump element needs a longer run time to
reach the full output capacity. Therefore, trigger several addi-
tional lube cycles.
*
Trigger several additional lube cycles. Lubricant must be
dispensed without air bubbles (towards the lube point).
*
Change lubricant. Consider table of lubricants.
*
Remove pump element. Check suction hole for foreign
particles. If there are any, remove them.
*
Replace pump element.
*
Replace pump element.
Cause:
Piston detector (initiator) defective.
Blockage in the system
Cable connections from the piston detector towards the
pump interrupted.
Printed circuit board defective.
Pump motor does not stop dispensing (30 minutes monitoring time)
