Check circuit breaker CB1 and reset if necessary.
The contactor
K9 is not providing positive voltage to
the K11 and K12 contactor coils.
1. Check the K9 contactor coil resistance. If the coil
resistance is not 118 ohms ± 10%, replace the
contactor.
1. Check the continuity through contactor K9 with the
coil energized. If the contacts are open, replace
the contactor.

K11 and K12 are not providing
voltage to the Hydraulic Pump/Motor Assembly M10.
1. Check the coil resistance on the K11 and K12
contactor. If the coil resistance is not 117 ohms ±
10%, replace the contactor.
1. Check the continuity through contactors K11 and
K12 with the coil energized. If the contacts are
open, replace the contactor.
2. Check the J2-28 and J2-24 Outputs from A1 Main
Machine Controller.
Check the motor wiring and connections from
contactors
K11 and K12 to the hydraulic pump motor,
and the ground connections from the contactors to
