7 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 can also be started by opening of a external contact (models with remote control).Off-Delay TimerSupply Voltage Output ContactSPDT (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.

8 If the energization time or closing time of the control contact is less than the minimum time specified, the timing period does not and Off-Delay TimerSupply Voltage Output ContactSPDT (C/O)This function is a combination of the On and Off delay functions. The timing cycle must be controlled by an external On and Off delays are On and Off delays are adjusted by 2 different Timer (Pulse On Energization)Supply VoltageOutput ContactSPDT (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 with Pulse On De-Energization or On Opening of a External Control ContactSupply VoltageOutput ContactsSPDT (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 star contactor returns to its initial position and the delta contactor closes, after a breaking time sufficient for the of Steven Engineering , Ryan Way, South San Francisco, CA 94080-6370-Main Office: (650) 588-9200-Outside Local Area: (800) Timers - RE7 Additional Functions506/2004 1993-2004 schneider Electric All Rights Reserved Please consult your Regional Sales Office.

10 1C/O = SPDT = 2 C/O = DPDT = Additional FunctionsExternal Control of Starting: Opening of an external contact connected to the timer starts the timing period. Closing of this contact resets the External Control of Timing: Closing of an external contact connected to the timer allows the timing period to be interrupted. The time elapsed is memorized. Timing restarts as soon as the contact opens. This type of control enables the totalizing function to be Adjustment of the Time Delay: One or more external potentiometers can be used for remote adjustment of the timing period or periods.
