6-3 Ten Year Inspection/Maintenance
It is recommended that the following, more extensive, maintenance is performed at ten (10) year intervals
to ensure the proper, long term, working condition of the Hawk actuator:
Quarterly visual inspection
Install soft goods repair kit (includes cylinder, manifold, and HPS soft goods)
Install accumulator/reservoir soft goods repair kit, if applicable
Replace HPS solenoids
Replace servo motor(s)
Replace pump
Purge and replace hydraulic fluid
7. TROUBLESHOOTING
Drive Diagnostic is displaying
F8022 error code
Interference between motor and
encoder
A F8022 error typically indicates
interference between the motor
power and motor encoder wiring. This may be caused by
unshielded motor power and encoder wires being in close proximity
to each other, exposed shielding making contact with the metal
Control Enclosure housing, or improperly wired motor and encoder
wiring.
In some instances, F8022 errors may also be caused by improper
motor encoder wiring (similar to C0285 errors) or power supply
wiring (similar to E8260 errors). In these cases review the C0285 and
E8260 troubleshooting entries for possible remedies.
Drive Diagnostic is displaying
C0285 error code
Motor encoder wiring is incorrect
A C0285 error indicates improper motor encoder wiring. This could
be due to improperly landed field wiring or physical damage to
wiring. After wiring errors are corrected, power to the actuator must
be cut and then restored to reset and remove the error.
Drive Diagnostic is displaying
E8260 error code
Power supply wiring is incorrect
A E8260 error indicates the phases of the power supply wiring are
incorrect. Be sure to depower the actuator before making any
changes to power wiring.
Actuator movement is "jerky" or
rough
Excessive air is in the hydraulic
fluid system and must be purged
Follow the Hydraulic Power Source (HPS) & Actuator Fluid Fill
Procedure to properly purge the hydraulic fluid system of air.
Actuator movement is delayed
after command signal is
changed
Excessive air is in the hydraulic
fluid system and must be purged
Follow the Hydraulic Power Source (HPS) & Actuator Fluid Fill
Procedure to properly purge the hydraulic fluid system of air.
Actuator cycles or is unable to
hold a position
There is internal leak-by
somewhere in the hydraulic fluid
system
Leak-by in the hydraulic fluid system will cause the actuator to
constantly cycle as it drifts and then repositions itself back to the
correct position. Leak-by may occur in the solenoid seals or in the
