8. TROUBLESHOOTING
The following diagnostic table indicates the main anomalies which may be encountered, the probable causes
and possible solutions.
If you cannot solve the problem, do not attempt to disassemble the unit, but
contact the Engineering Department of DROPSA S.p.A.
8.1 PUMP DIAGNOSTICS (MANUAL AND AUTOMATIC
SMART2
)
ANOMALY
PROBABLE CAUSE
SOLUTION
Pump does not deliver
lubricant.
Pump does not deliver the
fixed amount of lubricant
•
Pump draws off air
because the reservoir
is empty.
→
Refill the reservoir and vent air
from the system.
•
Loosened inner
fittings.
→
Retighten all the fittings.
Be sure there are no
Leakages.
•
Wear of the pump.
→
Replace the pump.
Pump delivers oil at an
improper pressure
•
Wrong calibration of
the by-pass valve.
→
Install a manometer to adjust
by-pass at the proper
pressure.
The system stays in
pressure at the end of the
lube cycle
•
Vent valve damaged
or dirty.
→
Inspect and clean the valve.
Replace it, if necessary.
