GSC300 12/24VDC SYSTEM OPERATION

The GSC300 controller is designed to operate in either 12 or 24 VDC system voltages.

When operating in 12VDC systems the fuel, crank and preheat/ets relays need to be the

proper 12VDC relay type. When operating in 24VDC systems these relays need to be the

proper 24VDC relay type. Contact the factory if relays are required.

Approved relays for 12 or 24VDC system operation are as follows:

•

AZETTLER – AZ973-1C-12DC for 12VDC operation

•

AZETTLER – AZ973-1C-24DC for 24VDC operation
