Mode functions

On application of supply voltage the time period starts to run. On completion of time the relay energises. Power

off reset.

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 ).

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
