HYDRAULIC SYSTEM
TROUBLESHOOTING:
SOLENOID VALVES FAILED TO OPERATE
1.
Voltage too low will not complete the stroke of alternating current (AC) and the solenoid
will burn out the coil.
2.
Signal to both solenoids of a double solenoid valve simultaneously. One or both of
the valves will be unable to complete their stroke and burn out. Make certain the
electrical signal is interlocked so that this condition cannot exist.
3.
Incorrect voltage or frequency will prevent operation or burn out coil.
4.
Foreign matter in valve.
5.
Oil too hot.
PUMP
1.
Excessive noise caused by vacuum leak in suction line.
2.
Misalignment of drive mechanism will cause high noise level in operation.
3.
Relief set too high.
4.
Return line above fluid level.
5.
Reversed rotation.
6.
Filter breather plugged.
7.
Viscosity of oil too high.
8.
Loose or worn pump parts.
9.
Air leak at pump shaft seal.
10. Oil too low, drawing in air.
