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) Turn the mode selector until PO is displayed. When power is ON, applying the start signal turns the NO (normally open) timed contact ON after the set time has elapsed. For power-on-delay operation, the start signal terminals (2 and 6) must be connected in advance. The timer is reset by the removal of power or by applying a reset signal. 3. One-shot momentary actuation * * * OS Turn the mode selector until OS is displayed. When power is ON, applying the start signal instantly turns the NO timed contact ON and turns it OFF after the set time has elapsed. Removing power while the timer is in operation or applying a reset signal resets the timer. Dimensions (mm) * * * Turn the mode selector until FL is displayed. When power is ON, applying the start signal turns the timed contact ON and OFF repeatedly at the set time intervals. The timer is reset by the removal of power or by applying a reset signal. 4. Signal off-delay * * * FL SF Turn the mode selector until SF is displayed. When power is ON, applying the start signal instantly turns the NO timed contact ON. Removing the start signal turns the contact OFF after the set time has elapsed. Removing power while the timer is in operation or applying a reset signal resets the timer.

The start signal itself will also effect a reset first. In mode 2, if another start signal is applied before timing is up, the elapsed time resets and starts again, without the output turning off. Further, repeated start signals within the elapsed time can prevent the output turning off indefinitely. Therefore, the TDMS can be used in conjunction with IMO sensors to detect that machine shafts have stopped rotating before maintenance is carried out. Contact IMO for details. Timer TA11-A 1.

Timing will resume at the point where it left, as soon as the gate signal is removed. * Each signal can be input by short circuiting the relevant terminals. * Power LED lights up when power is ON, but flickers during timing.
