The GM156 DIN RAIL REPEAT START TIMER is a low cost printed circuit board (PCB) assembly designed for panel mounting in ‘prime mover’ applications. On application of a supply voltage, an internal relay energizes for a preset cranking time. Should the engine fail to start, the timer pauses for an equal period then provides a further cranking signal. If after three attempts at starting. The engine still fails to come up to speed, a failed to start relay is energized, and no further cranking can be made until the unit is reset by breaking the supply voltage. The unit must be re-energized when the engine comes up to speed.
NOTE: The GM156 is one of a range of low cost PCB assemblies designed for OEMs to assemble their own control cubicles for use with automatic standby diesel generator sets and fire pumps etc.
