CLAMP AS-TURBINE 9N2038 - Caterpillar

The generator output voltage level can be controlled from a remote location. The generator output voltage can be controlled with the use of a remotely mounted voltage adjust potentiometer. In order to control the voltage from a remote location, perform the following steps:
Remove the jumper between terminals 4 and 7.

The Cat VR6 presents an electrical shock/electrocution hazard. This hazard will cause serious injury or death.Service by trained personnel only.The terminals and heat sinks are live at hazardous voltages when power is applied and for up to 8 minutes after power is removed.
Connect a 10 K Ohm, 2 Watt potentiometer between terminals 6A and 7 on the voltage regulator.For an acceptable voltage control, the remote mounted potentiometer must be 10 K Ohm +5% with three turns or more and a dielectric strength of 1000 VAC minimum. The terminals of the remote mounted potentiometer are fragile. The wiring that is connected to a remote mounted potentiometer, should not have a diameter larger than 18 gauge. A wire with a larger diameter is not recommended. The wire should be 600 Volt class with 90 °C (194.0 °F) insulation.When the remote potentiometer is mounted a long distance (up to 15.24 m (50 ft)) from the generator set, a shielded cable may be necessary in order to isolate the signal from noise.
