ESR 3.1 engine starter relay offers excellent functions for manual control of diesel and gasoline engine powered generators.
The operator can start and stop the engine automatically from the front panel push buttons, the unit also provides remote starting of the generator via an external signal. ESR 3.1 is also provided with alternator phase voltage input terminals so that the unit can monitor and protect the generator against over/under speed and over/under voltage failures automatically.
All these readings can be rolled on the display via the push button on the front panel. The control unit contains a 5 digit 7-segment LED display. The operator can monitor the alternator frequency, engine RPM, working engine hours from the front panel, thus avoiding the use of analog type meters on the control cabin.
Other features include monitoring of oil pressure, engine temperature, auxiliary fail input and charge alternator failure.
