5. Operating Instructions

Once installed and wired correctly, the EPC20 controller will manage the generator set's operations. Specific operational procedures will depend on the overall generator system it is integrated into.

5.1 Initial Power-Up

After verifying all connections, apply power to the generator set and the EPC20 controller.
Observe any indicator lights on the controller or associated panels for normal operation status.

5.2 Automatic Throttle Function

The controller automatically adjusts the engine throttle based on load demands and pre-set parameters to maintain stable engine speed and output.

5.3 Protection Functions

The four protection modules continuously monitor critical generator parameters. In case of an anomaly (e.g., over-speed, low oil pressure, high temperature), the controller will initiate a protective shutdown or alarm to prevent damage to the generator set.
