UL File Number E158650

The ACI Twin Setting Repeat Cycle Timer features two timers in one case, acting as a continuously functioning repeat cycle timer. The twin setting repeat cycle timer allows independent setting of both "on" and "off" time. This provides the needed flexibility required for many timing applications.

When power is applied to the timer coil, the lead timer immediately begins its time delay. Once the lead timer's delay is reached, the relay contacts transfer and remain transferred until the lag timer's delay setting is reached. The relay contacts are released, both timers are reset and the timing cycle automatically begins. Both the lead and the lag timer can be set at any point from zero to full scale by adjusting the twin knobs. Any pattern of relay contacts "ON" and "OFF" can be achieved.

Note: Not for direct motor starting.
