Microcontroller based solution for simple and minimal applications
The control unit provides full protection of the engine parameters display the state of the system with front panel indicators and offer an efficient management of the engine.
ESR 1.1 engine starter relay offers a very efficient method of starting and stopping any diesel and gasoline engine while providing full protection for the engine.
The operator can start and stop the engine manually, via the ignition key-switch mounted on the front panel of the unit. ESR 1.1 is also provided with alternator phase voltage input terminals so that the unit can monitor and protect the generator against over/under speed failures.
The control unit contains a 3 digit 7-segment LED display in order to display the alternator frequency on the front panel, thus avoiding the use of analog type frequency meters on the control cabin.
Other features include monitoring of oil pressure, engine temperature, auxiliary fail input and charge alternator failure.
