CAUTION: Do not touch terminals 5, 6 and 7 while power is applied to the timer. Please see page 109 for timing diagrams 1. On-delay PO 2. Flicker (Repeat cycle) FL Turn the mode selector until PO is displayed. Turn the mode selector until FL is displayed. When power is ON, applying the start signal turns the NO (normally When power is ON, applying the start signal turns the timed contact open) timed contact ON after the set time has elapsed. ON and OFF repeatedly at the set time intervals. For power-on-delay operation, the start signal terminals (2 and 6) The timer is reset by the removal of power or by applying a reset must be connected in advance. signal. The timer is reset by the removal of power or by applying a reset signal. 4. Signal off-delay SF 3. One-shot momentary actuation OS Turn the mode selector until SF is displayed. Turn the mode selector until OS is displayed. When power is ON, applying the start signal instantly turns the NO When power is ON, applying the start signal instantly turns the NO timed contact ON. Removing the start signal turns the contact OFF timed contact ON and turns it OFF after the set time has elapsed. after the set time has elapsed. Removing power while the timer is in operation or applying a reset Removing power while the timer is in operation or applying a reset signal resets the timer. signal resets the timer.
