OPTION 1: SENSOR DETECTING TARGET ON PADDLE -

Under normal running conditions, the target bolt passes through the sensor's field and a pulse is sent to

the speed relay. If the chain becomes slack, the target bolt will drop below the field and the pulses will

stop, causing the relay contact to change state.

OPTION 2: SENSOR DETECTING STEEL FLIGHT -

Under normal running conditions, the steel flight passes through the sensor's field and a pulse is sent to

the speed relay. If the chain becomes slack, the steel flight will drop below the field and the pulses will

stop, causing the relay contact to change state.

OPTION 3: SENSOR WAITING TO DETECT STEEL FLIGHT -

Under normal running conditions, the steel flight is out of the sensor's field, so no pulses are sent to the

speed relay. If the chain becomes slack, the steel flight comes into the sensor's field and a pulse is sent

to the speed relay, causing it to change state.
