**(AI) On-delay.** Apply power to timer. Output contacts transfer after preset time has elapsed. Reset occurs when power is removed. **(DI) Interval.** Apply power to timer. Output contacts transfer immediately. After the preset time has elapsed, contacts reset. **(GI) Pulse delayed.** Apply power to timer. Output contacts transfer after preset time has elapsed. Reset occurs after a fixed time of 0.5 s. 

**==> picture [273 x 72] intentionally omitted <==**

with control signal 

**==> picture [155 x 45] intentionally omitted <==**

**(SP) Symmetrical flasher (starting pulse off).** Apply power to timer. First transfer of contact occurs after preset time has elapsed. The timer now cycles between OFF and ON as long as power is applied. The ratio is 1:1 (time on = time off). **(BE) Off-delay with control signal.** Power is permanently applied to the timer. The output contacts transfer immediately on closure of the Signal **H** Switch (S). Opening the Signal Switch initiates the preset delay, after which time the output contacts reset. **(CEa) On- and off-delay with control signal.** Power is permanently applied to the timer. Closing the Signal Switch (S) initiates the preset delay, after which time the output contacts transfer. Opening the Signal switch initiates the same preset delay, after which time the output contacts reset. 

**(DE) Interval with control signal on.** Power is permanently applied to the timer. On momentary or maintained closure of Signal Switch (S), the output contacts transfer, and remain so for the duration of the preset delay, after which they reset. 

## **RESET (R)** 

A momentary closure of the reset switch (2-7) will reset the timer. Longer term closure of the reset switch will hold the timer in the reset state. This is applicable for all functions. 

## **PAUSE (P)** 

Closure of the pause switch (2-5) will immediately halt the timing process, but the elapsed time will be retained, and the current state of the output contacts will be maintained. 

On opening of the pause switch, timing resumes from the retained value. This is applicable for all functions.
