Output contacts transfer after preset time has elapsed. Reset occurs when power is removed. T 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. t<T (SW) Symmetrical recycling: ON start. Apply power to timer. Output contacts transfer immediately and cycle between ON and OFF for as long as power is applied. The ratio is 1:1 (time on = time off). (BE) Signal OFF delay. Power is permenently applied to the timer. The output contacts transfer immediately on closure of the Signal Switch (S). Opening the Signal Switch initiates the preset delay, after which time the output contacts reset. (CE) Signal ON and OFF delay. Power is permenently 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) Signal ON pulse. Power is permenently 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. 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. 3 88 Series - Plug-in timers 5 - 8 A Functions Wiring diagram Type 88.12 without signal START 2 7 4 (Al a) ON Delay (2 timed contacts). Apply power to timer.
