Abbreviations
The following abbreviations are used in test voltage tables:
Pumps Hoist Motors Travel Motors
0 to 25.4 Volts (at Node) 3.8 to 14 Volts (at Node)
0 or 28 Volts (at Node)
2
0 to 2.0 Volts (at Pump) 3.8 to 14 Volts (at Motor)
0 or 28 Volts (at 2-Speed Solenoid)

1 to 100 mA

180 mA to 600 mA

Resistance increases as the temperature rises on the pump or motor control coil resulting in decreased current values
when measured with a meter. The listing in the table is the current range for a 21°C coil.
2
Travel motor control is two-speed. When the travel motor control solenoid is energized, the motor is locked in max
displacement. When the motor control solenoid is de-energized, the pressure compensator will shift the motor to min
displacement. The Master Node will only de-energize the coil if the 2-Speed Travel Switch is in the high speed position
and the engine RPM is above 1500. The pressure compensator override will begin to shift motor back to max
displacement, low speed as the closed loop pressure reaches or exceeds 3915 to 4200 PSI (270 to 290 BAR) in order
to stabilize and hold the pressure constant protecting the motor from over heating and catastrophic failure.
3
The Master Node regulates displacement of the hoist motors by the EDC control on the motor. 180 mA the coil is at rest
and the motor is in max displacement. 750 mA the coil is fully energized and the motor is in min displacement.
