Cause
Block switch A or B did not change
state at least once (either from
opened to closed or vice-versa)
during a number of pump cycles
in succession, making it uncertain
whether grease still reached this
distribution block, possibly caused
by:
1: Grease leakage in the primary
line
2: Pump does not deliver grease
3: Defective divider block switch
Control unit detected a too high
current draw to pump motor and
aborted the attempted cycle,
caused by:
Drive shaft blocked
Control unit detected a short circuit
and aborted the attempted pump
cycle,possibly caused by:
1: Short circuit in the wiring pump
motor
2: Short circuit in pump motor
3: Short circuit in control unit
Control unit detect a unusual re-
sistance in the pump motor circuit.
1: interrupted wiring
2: Defective motor
3: Corroded contact
4: Defective control unit
Control unit encounterd corrupted
parameters during power up and
restored to default settings.
normal:
1: Grease temperature is very low
and the pump has difficulty greas-
ing;
2: A piston is mounted wrong in
one of the pump outlets and is
blocking the motor.
before the end of the current pump
cycle, causing the pump to be
continuously pumping
Solution
1: Check for leakage
2: Check pump output
3: Check switch
Check pump or pistons for dam-
age or blockage and repair or
renew pump section.
1: Check wiring harness between
pump and circuit board.
2: Check the resistance of the
motor
3: Replace control unit
1: Check wiring harness
2: Check the resistance of the
motor.
3: Check wiring harness
4: Replace control unit
Replace the control unit
1: No action needed.
2: Check pump outlet for internal
damage and reinstall correctly
Check the parameter interval time
and pump revolutions.
