4310A-8-B-2 - 

Model 4310 can perform as an interval timer or as a single-shot timer. The difference between interval and single-shot operation is the operation of the initiate switch. If the load is to operate from a continuous closure from the initiate switch, wire the timer with no jumper between terminals 6 and 7. In this mode, the Model 4310 will function as an interval timer. If the load circuit is to operate for the entire timing period even if the initiate switch is closed for a short duration, connect terminals 6 and 7 and operate as a single-shot timer. In single-shot operation the power switched to the load cannot be removed with the initiate switch once the cycle has been initiated. 10 A zero voltage switching. Other voltages and times available from factory.
