The thermal sensors are mounted on the motor brush holders and connected to the main wire harness with
connectors 1X7, 1X8 and 2X7. Depending on the temperature, the resistance of the thermal sensors changes
according to the following characteristic line:
Resistance
Temperature
Test:
- Jack up the truck and support it safely.
- Actuate the emergency stop switch.
- Disconnect the connector to the motor in question.
- Measure the resistance between connector 1X7 or 1X8 at terminals :3 and :4. When the motor is cold (25
°C), the resistance should be approx. 500 Ohm.
- Drive the truck until the motor reaches operating temperature.
- Measure the resistance again. When the motor is warm (80 °C), the resistance should be approx. 800
Ohm.

SPEED REDUCTION
To limit the speed of the electric fork trucks it is necessary to separate the bridge between 1X13:27 and
1X13:38 and to solder fixed resistor 1R1. This fixed resistor is switched via an auxiliary 24 V relay 1K7. As
soon as regenerative braking is activated, the speed reduction is cut out by the regenerative current contactor
with microswitch 1S10.
NOTE:
Only the travel speed of the truck will be reduced. The maximum climbing ability of the truck
does not change. The resistance of 1R1 can be determined according to the following table.
Replacement parts for the speed reduction are available as custom equipment (UPA).
