DESCRIPTION

This is  a compact micro-electronic device made up of latest c-mos electronic components and other components of the highest quality available. This device is used to automatically switch ON and OFF the priming pump of the diesel generators periodically, in case of non-use of the generator. When the operating supply is connected to the device it starts counting the time and after the set OFF-time its relay gets

energised for the set ON-time. This cycle of "OFF & ON TIME" continues till the operating supply is connected. Therefore to achieve the function of priming of generator, the operating supply of the device should be connected when the generator is OFF and the relay of the device should be used to put ON and OFF the priming pump.
