  • Page 3: Overview

    1. OVERVIEW HGM1770 is a genset automatic start module with 3 working modes that can be selected from the front panel. It can be started and stopped manually or via a remote start/stop signals. In case of faults (such as low oil pressure, high water/cylinder temperature, emergency stop alarm, over speed), HGM1770 can automatically disconnect fuel relay and close ETS electromagnet to stop the generator.

    5. PROTECTION 1) Low Oil Pressure: detection begins after safety delay; if low oil pressure lasts for 2s, shutdown is initiated. 2) High Temperature: detection begins after safety delay; if high temperature lasts for 3s, shutdown is initiated. 3) Low Fuel Level: if fuel level stays below the pre-set level for 10 seconds, low fuel level warning signal is sent.
