Abstract:
1. An apparatus for connecting two generators to an electrical load through conductive paths running in parallel, comprising: a single remote controller provided independently and separately from the apparatus, the remote controller including a start switch and a stop switch that are manipulated by an operator; a first group of terminals that is connected to the remote controller; a second group of terminals that is connected to each remote control terminal of the generators; an electronic control unit that is connected to the first and second group of terminals and starts/stops each of the generators by outputting signals to each of the generators through the second group of terminals in accordance with a start instruction signal and a stop instruction signal produced in response to the operator's manipulation of the start switch and stop switch and inputted through the first group of terminals; and a relay driver which drives a switching circuit that connects the first generator and the second generator to a load; wherein the electronic control unit further comprises: the first generator has a first generator controller and the second generator has a second generator controller; the first instruction section instructs the relay driver to drive the switching circuit in response to the operator's manipulation of the remote controller; the second instruction section instructs the first generator controller to start the first generator and conducts the photocoupler to electrically connect the second and third instruction sections when a first instruction signal produced in response to the operator's manipulation of the start switch is sent from the remote controller through the first instruction section; and the third instruction section instructs the second generator controller to start the second generator when a second start instruction signal produced in response to a next operator's manipulation of the start switch is sent from the remote controller through the first instruction section and the conducted photocoupler.
