Wiring Diagram

A diagram shows the internal connections of the time switch. Key components labeled include: TIME POINTER, TIME DIAL, OFF TRIPPER, MANUAL LEVER, ON/CUTOUT TRIPPER, DAY ARROW, SKIPPER WHEEL, SKIPPING SCREW, CLOCK MOTOR. The wiring diagram illustrates connections for SUPPLY, GROUND SCREW, and TO LOADS, with terminals labeled A, B, and (4PST).

Wiring Instructions

Remove 1/2 inch of insulation from wire ends. Tighten terminal screws firmly (2-18 in-lbs). Use solid or stranded COPPER conductors only. May use two wires of the same size and type.

Programming Instructions

1. To Set "ON" and "OFF" Times: Hold trippers against the edge of the CLOCK-DIAL, pointing to the time (AM or PM) when ON and OFF operations are desired. Tighten tripper screws firmly. See caution below. For additional tripper pairs on CLOCK-DIAL, order 156T1948A.
2. To Set Time-of-Day: Pull CLOCK-DIAL outward. Turn in either direction and align the exact time-of-day on the CLOCK-DIAL (the time now, when switch is being put into operation) TO TIME POINTER. DO NOT MOVE THE POINTER.
3. To Skip Operation(s) on Selected Day(s): Insert SKIPPING SCREW(S) in SKIPPER WHEEL for the day(s) automatic operation(s) is/are NOT required. Tighten screws firmly. Move MANUAL LEVER to "OFF" and rotate SKIPPER WHEEL to locate the correct day-of-week opposite DAY ARROW -- "YESTERDAY" if ON/CUTOUT TRIPPER has not yet advanced wheel "TODAY" if it has.

Operating Instructions

• To Operate Switch Manually: Move MANUAL LEVER below CLOCK-DIAL left or right as indicated by arrows. This will not affect the next operation.
• Caution: TO AVOID SLOW TRIPPER ACTION FAILURE, DO NOT OPERATE SWITCH MANUALLY NOR PLACE A TRIPPER 4 HOURS PRIOR TO ON/OFF CUTOUT TRIPPER SWITCHING.

Power Failure Reset

In case of power failure, reset CLOCK-DIAL to proper time-of-day. See programming instructions.
