See 700FS Timing Charts (A) On-delay The output contact changes state after the time delay is completed.

(B) Off-delay Input power must be supplied to terminal (A1/A2) continuously. The output contact changes state when switch S is closed. When switch S is opened, the time delay begins. After the time delay is completed, the contact returns to shelf state. (C) On- and off-delay Input power must be supplied to terminal (A1/A2) continuously. The output contact changes state when switch S is closed and the time delay complete. When switch S is opened, the time delay begins again. After the time delay is completed, the contact returns to shelf state. (D) One shot The output contact changes state when the relay is energized. The output contact returns to shelf state when the time delay is completed. (E) Fleeting off-delay (Min. Pulse AC 50ms DC 30ms) Input power must be supplied to terminal (A1/A2) continuously. The output contact changes state after closing and opening switch S. After the time delay is completed, the contact returns to shelf state. (F) Flasher (Repeat Cycle Starting with Pulse) The output contact changes state when power is applied. At the end of the time delay, the output contact returns to shelf state. This cycle continues until the power is removed.

See 700FS Timing Charts (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). 700FSH3U provides (1) range setting for t1 and t2. 700FSH3V provides (2) range settings for t1 and t2. Supply voltage controlled, Oscillating Mode starting with pause Switch is Up Supply voltage controlled, Oscillating Mode starting with pulse Switch is Down Pulse controlled, output starts with pulse (Min.

OnDelay (Pulse Controlled) (J) Pulse Starts The OnDelay that Turns On a Motor

A1 and A2 must be energized continuously. A pulse or input from the ON Pressure Switch starts the OnDelay. After the delay is complete, the Motor 1M will start. A signal from the Reset Pressure Switch turns the Motor 1M off. The delay prevents short off times.

One Shot/Watch Dog (Pulse Controlled) (K) Conveyor Keeps Running Only As Long As a Package is Sensed Every Time Setting (5 Min)

A1 and A2 must be energized continuously. A pulse must be received every time setting (or sooner) to maintain the Motor 1M running. This could be an energy saver, because the Motor 1M will turn off if the Photo SW is open for a period of time.
