Troubleshooting
Mode of failure
Solution
Pump motor does not run. No green right corner segment lit on
display (
† Fig.
,
page
).
Check power supply and fuses.
Pump does not deliver lubricant but runs if manual lube switch (
)
(
† Fig.
,
page
) is pushed. No green left corner segment lit
on display (
† Fig.
,
page
).
Check count switch for V
pulse.
LL
display is flashing. Reservoir is almost empty.
Refill reservoir and push switch (
) (
† Fig.
,
page
)
to initiate manual lube cycle.
E
display is flashing. Pump failed to develop internal pressure
in minutes.
Push switch (
) (
† Fig.
,
page
) to acknowledge fault.
Initiate manual lube cycle. Investigate and correct possible causes –
air pockets, broken line, connections leakage, worn pumping element,
failed internal pressure switch or pressure transducer. Initiate
manual lube cycle.
E
display is flashing. Pump failed to develop pressure at
end of line (pump with external pressure switch or
pressure transducer).
Push switch (
) (
† Fig.
,
page
) to acknowledge fault.
Initiate manual lube cycle. Investigate and correct possible causes –
air pockets in lubrication line, connections leakage, grease consistency
changed with low temperatures, failed end of line pressure switch
or pressure transducer.
E
display is flashing. Pump failed to vent at pump.
Push switch (
) (
† Fig.
,
page
) to acknowledge fault.
Initiate manual lube cycle. Investigate and correct possible causes –
pump eccentric did not stop in proper position, vent valve failed.
E
display is flashing. Pump failed to vent at end of the line
(pump with external pressure switch or pressure transducer).
Push switch (
) (
† Fig.
,
page
) to acknowledge fault.
Initiate manual lube cycle. Investigate and correct possible causes –
restriction in lubrication line, grease consistency changed with low
temperature, failed end of line pressure transducer or pressure switch.
Grease is coming out of pressure relief valve (
) (
† Fig.
,
page
).
Check and adjust setting of pressure transducer or failed
pressure switch.
