True Off Delay
When supply voltage U is engaged the relay energises (contacts 15-18). When the supply voltage is removed
the set time t begins to run. On completion of time t the output falls back to the off position (contacts 15-16). If
the supply voltage U is re-engaged to “the unit before t has elapsed, the time already elapsed is cancelled” and
starts again next time the supply voltage is interrupted.
On Delay
On application of supply voltage the time period starts to run. On completion of time the relay energises. Power
off reset.
On delay with control contact
Supply to the unit must be continuous. On closure of (S) the time period starts to run. On completion of time
the relay energises and stays energised as long as (S) is closed. Opening the control contact before the time
out is complete will reset the time period.
Single shot leading edge
On application of supply voltage the time starts and (R) energises immediately. Following time out the relay will
de-energise. For a new start of function the supply voltage must be interrupted.
Star Delta
On application of supply voltage the contact 17 - 18 of the star relay is closed and the star time t1 begins to
run. On completion of the t1 the star relay de-energises and the dwell time t2 starts. On completion of t2 the
contact 17 - 28 of the delta relay is closed and remains in operation as long as the supply voltage is applied.
Off delay
Supply to the unit must be continuous. On closure of the control contact (S) the relay energises immediately.
On re-opening of S the time period starts to run and (R) de-energises If the control contact ( S ) is reclosed
before “the actual time period is completed, this period will be deleted” and a new one starts on re-opening of (
S ).
Single shot leading edge pulse started
Supply to the unit must be continuous. On closure of the control contact (S) the relay energises immediately
and the time starts to run. On completion of the time the relay will de-energise. Activation of (S) during the time
out period has no effect.
Single shot trailing edge
Supply to the unit must be continuous. The first closure of (S) has no effect. On opening of ( S ) the time
period starts to run and (R) energises immediately. On completion of time the relay de-energises. Activation of
the control contact (S) during the time out period has no effect.
Flasher pause first
On application of supply voltage the time period starts to “run. The relay switches on and off for the periods,
beginning” with a pause. The time period for pause and pulse is equal.
Pulse detection
On application of supply voltage the relay energises. The first pulse of (S) starts the time period. Receiving
pulses during the time period extends it and (R) stays energised. Receiving no pulses during the time period
completes it and (R) de-energises. (R) stays latched until supply voltage has been interrupted.
Cyclic timer pulse started
On application of supply voltage the time period starts to run. “The relay switches on and off for the periods,
beginning with a” pulse. The time period for t1 and t2 can be different. The function continues as long as
voltage is applied.
Cyclic timer pause started
On application of supply voltage the time period starts to run. “The relay switches on and off for the periods,
beginning with a” pause. The time period for t1 and t2 can be different. The function continues as long as
voltage is applied.
