The REST cycle is a pause in the cranking sequence and only applies if Dip Switch 4 on the module is in the
Off position. In this mode Fuel is still applied to the engine but the Starter Relay signal is turned off. The cycle
continues for the duration of the Cycle time Adjustment Setting. The Low Oil Pressure fault signal input is
ignored. To set Cycle Time and Crank Attempts see adjustments page .

If the internal speed switch detects a speed equal or above the Crank Disconnect Adjustment Setting the
starter relay signal
turns off, the Low Oil Pressure delay timer is initiated and the appropriate signals indicate as
shown. The LED versions indicate via an LED also. This is a latched condition and must be reset by placing the
Engine Control
Switch in the Off position. The internal speed switch uses the Magnetic Pickup for speed
detection.
