Z-40/23N, Z-40/23N RJ
Part No. 1268528
Drive Motor Thermal Sensor
The thermal sensor is monitored by the motor
controllers to maintain optimum performance and
as a thermal shutdown protection device.
Normal safe operating range is between -40°F /
-40°C and 131°F / 55°C at an 85% duty cycle.
Thermal faults will occur when the temperature
exceeds its threshold of 302°F / 150°C. Then drive
speeds will be reduced by 50%.
Thermal shut down occurs at 392°F / 200°C.
How to Test the Thermal Sensor
1 Disconnect the battery packs from the
machine.
Electrocution/burn hazard.
Contact with electrically charged
circuits could result in death or
serious injury. Remove all rings,
watches and other jewelry.
2 Remove the chassis cover fasteners from the
non-steer end of the chassis. Remove the
cover.
3 Remove the fasteners from the axle covers
from the non-steer axle. Remove the covers.
4 Tag and disconnect the six pin Deutsch
electrical connector for the speed and
temperature sensor at the drive motor.asure
the drive motor case temperature using a
thermometer.
5 Measure the drive motor case temperature
using a thermometer.
6 Measure the resistance between pins 5 and
6 on the Deutsch connector going into the
motor housing. Compare value to chart on
right.
