The Crank Cycle timer (DE008) is a small unit intended for use as a starter motor cranking timer in auto start standby alternators.
It is housed in an impact resistant polystyrene case with connections brought out as an eleven pin base to plug into a conventional relay socket.
On application of a 24V DC signal, an internal relay will function for a preset time then release. Up to four cycles may be programmed. A “failed to start” signal will be activated if the input voltage is not removed before the last crank cycle.
The unit must be de-energised externally when the engine comes up to speed.
