(H) Flasher (repeat cycle starting with pulse or pause)

The repeat cycle timer permits different settings for on and off times.

The following operating modes are possible:

–Oscillating mode; repeat cycle starts with voltage applied at A1 and B1, and continues to repeat until voltage is off.

–One cycle mode; started by energizing B1 with voltage on A1 and A2.

–Output starts with pulse or pause (switch ⊗ Up or Down).

Motor 1M will start. A signal from the

“Reset” Pressure Switch turns the Motor
