zelio-time tm timers - re7 timing functions ? 1993-2004 schneider electric all rights reserved 4 06/2004 timing functions operating diagram operating principle on-delay timer supply voltage output contact spdt (c/o) timing starts when the timer is energized. when the set time delay (ta) has elapsed, the output contact closes. when the timer is de-energized, the output contact returns to its initial position. the output contact does not close if the duration of the control instruction is less than the set time delay. timing can also be started by opening of a external contact (models with remote control). off-delay timer supply voltage output contact spdt (c/o) energization of the timer or closing of the control contact (models with external control) causes the output contact to close instantaneously. timing starts when the timer is de-energized or when the control contact opens. when the set time delay (tr) has elapsed, the output contact returns to its initial position. if the energization time or closing time of the control contact is less than the minimum time specified, the timing period does not start. on and off-delay timer supply voltage output contact spdt (c/o) this function is a combination of the on and off delay functions. the timing cycle must be controlled by an external contact. symmetrical the on and off delays are equal. asymmetrical the on and off delays are adjusted by 2 different potentiometers. interval timer (pulse on energization) supply voltage output contact spdt (c/o) energization of the timer causes the output contact to close instantaneously and start the timing period. the output contact returns to its initial position when the set time delay (t) has elapsed or if the supply is cut off before the end of the timing period. timer with pulse on de-energization or on opening of a external control contact supply voltage output contacts spdt (c/o) de-energization of the timer or opening of the external control contact (depending on model) causes the output contact to close instantaneously and start the timing period. when the set time delay (t) has elapsed, the contact returns to its initial position. repeat cycle timer (flashing timer) supply voltage output contact spdt (c/o) energization of the timer starts the flashing period and causes the output timer to start the flashing cycle. when the timer is de-energized, the contact returns to its initial position. symmetrical flashing timer the timer flashes with a symmetrical on/off pattern. asymmetrical flashing timer the on and off flashing timers are adjusted by 2 different potentiometers. timers for star-delta starters supply voltage output contacts energization of the timer causes the star contactor to close instantaneously and starts the timing period. when the set time delay (t) has elapsed, the star contactor returns to its initial position and the delta contactor closes, after a breaking time sufficient for the changeover. ta tr ta tr t t t t t t3
