    In the case of any mains supply disproportion it will send a remote start command to the gen-set and make change over for both generator and mains contactors. The gen-set requires a remote start type control unit (e.g. the ComAp InteliLite MRS 10 controller), at least a key-start box with an external input for the start/stop signal.
