1. On-delay PO 2. Flicker (Repeat cycle) FL
T urn 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.
T urn 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.

T urn the mode selector until OS is displayed.
When power is ON, applying the start signal instantly turns the NO
timed contact ON and tur ns it OFF after the set time has elapsed.
Removing power while the timer is in operation or applying a reset
signal resets the timer.
T urn the mode selector until SF is displayed.
When power is ON, applying the star t signal instantly tur ns the NO
timed contact ON. Removing the star t signal tur ns 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.

Notes: A In modes 2 and 3, after the time is up and the output turns off, a reset signal is not required before another start signal is
given. The start signal itself will also effect a reset first.
Notes: B 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.
Notes: T = Set time, T-a=Time period within the set time.
Applying a gate signal pauses the operation, (timing does not continue during a gate signal). 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.
