ENGINE STARTER RELAY DESCRIPTION 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 2 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. Micro-controller based design Pre-glow heater control Low oil pressure failure detection High engine temperature failure detection Auxiliary input protection Charge alternator failure warning Fuel / Start solenoid output relay control Alarm Output contact Excitation Current feed for charge alternator unit Small Dimensions (72mmx72mm) Easy connection via screw terminal sockets High reliability concept design (MTBF > 50.000 hours) Front panel LED indicators for alarm status level Front panel 2 digit 7-segment LED display for frequency IP52 front panel protection class CE compliant 9-36Vdc supply voltage range PROTECTION FUNCTIONS • • • • • Low oil pressure protection High engine temperature protection Auxiliary input protection Charge alternator failure protection High-speed / Low speed protection Other features include monitoring of oil pressure, engine temperature, auxiliary fail input and charge alternator failure.
