Electronic timersCT-D rangeFunction diagrams

A ON-delay (Delay on make) CT-ERD, CT-MFD

Timing begins when supply voltage is applied to A1-A2. The green LED fl ashes during timing. When the selected time delay is complete, the output relay energizes and the fl ashing green LED turns steady.

If supply voltage is interrupted, the output relay de-energizes and the time delay is reset.

Interrupting supply voltage before the time delay is complete, resets the time delay. The output relay does not energize.

B OFF-delay with auxiliary voltage (Delay on break) CT-AHD, CT-MFD

This function requires continuous supply voltage at terminals A1-A2 for timing.

Timing is controlled by a control contact, connected to terminals A1-Y1. If the control contact is closed, the output relay energizes. If control contact A1-Y1 is opened, the selected time delay starts. The green LED fl ashes during timing. When the time delay is complete, the output relay de-energizes and the fl ashing green LED turns stea-dy.

If control contact A1-Y1 closes before the time delay is complete, the time delay is reset. Timing starts again when the control contact re-opens.

D Impulse-ON (Interval) CT-VWD, CT-MFD

The output relay energizes immediately when supply voltage is ap-plied to terminals A1-A2 and de-energizes after the selected time de-lay is complete. The green LED fl ashes during timing. When the time delay is complete, the fl ashing green LED turns steady.

If supply voltage is interrupted before the time delay is complete, the output relay de-energizes and the time delay is reset.

t = adjusted delay time t = adjusted delay time

t = adjusted pulse time

E Impulse-OFF with auxiliary voltage (Trailing edge interval) CT-MFD

This function requires continuous supply voltage at terminals A1-A2. Opening control contact A1-Y1, energizes the output relay immedi-ately and timing begins. The green LED fl ashes during timing. When the selected time delay is complete, the fl ashing green LED turns steady and the output relay de-energizes.

Interrupting supply voltage or closing control contact A1-Y1, before the time delay is complete, de-energizes the output relay and resets the time delay.

F Flasher starting with ON (Recycling equal times, ON fi rst) CT-EBD, CT-MFD

Applying supply voltage to terminals A1-A2, starts timing with sym-metrical ON & OFF times. The cycle starts with an ON time fi rst. The ON & OFF times are displayed by the fl ashing green LED, which fl as-hes twice as fast during the OFF cycle.


H Pulse generator starting with ON or OFF (Recycling unequal times) CT-TGD

Applying supply voltage to terminals A1-A2, starts timing. Timing starts with the OFF time fi rst. If a jumper wire is connected to input X2-Z2 (see below), the timer starts with the ON time fi rst. The ON & OFF times are displayed by the fl ashing green LED.


G Flasher starting with OFF (Recycling equal times, OFF fi rst) CT-MFD

Applying supply voltage to terminals A1-A2, starts timing with sym-metrical ON & OFF times. The cycle starts with an OFF time fi rst. The ON & OFF times are displayed by the fl ashing green LED, which fl as-hes twice as fast during the OFF cycle.


t = adjusted fl ashing time t = adjusted pulse time

tp = OFF-timeti = pulse timeA1-Y1 B (closed) = starting with OFFA1-Y1 K (open) = starting with ON

L Pulse former (Single shot) CT-MFD

Closing the control contact connected to terminals A1-Y1, with sup-ply voltage applied, energizes the output relay for the selected ON time. When the ON time is complete, the output relay de-energizes. Operating the control contact switch A1-Y1 during the time delay has no effect. The green LED fl ashes during timing. When the selected pulse time is complete, the fl ashing green LED turns steady and the output relay de-energizes.

After the time delay is complete, it can be restarted by closing control contact A1-Y1.

If supply voltage is interrupted during timing, the output relay de-en-ergizes and the ON time is reset.

Electronic timersCT-E range with relay outputFunction diagrams

A ON-delay (Delay on make) CT-ERE, CT-MFE

Timing begins when supply voltage is applied to A1-A2/B1. When the selected time delay is complete, the output relay energizes.


Interrupting supply voltage before the time delay is complete, resets the time delay. The output relay does not energize.

B OFF-delay, with auxiliary voltage (Delay on break) CT-AHE, CT-MFE

This function requires continuous supply voltage at terminals A1-A2 for timing.

Timing is controlled by a voltage-related (wet/non-fl oating) control contact, connected to terminals A1-Y1. If the control contact is closed, the output relay energizes. If control contact A1-Y1 is ope-ned, the selected time delay starts. When the time delay is complete, the output relay de-energizes.

If control contact A1-Y1 closes before the time delay is complete, the time delay is reset. Timing starts again when the control contact re-opens.

D Impulse-ON (Interval) CT-VWE, CT-MFE

The output relay energizes immediately when supply voltage is ap-plied to terminals A1-A2/B1 and de-energizes after the selected time delay time is complete.

If supply voltage is interrupted before the time delay is complete, the output relay de-energizes and the time delay is reset.

B OFF-delay, without auxiliary voltage (true delay on break) CT-ARE

The OFF-delay function without auxiliary voltage does not require supply voltage at terminals A1-A2/B1 for timing.

Applying supply voltage to terminals A1-A2/B1, energizes the output relay. If supply voltage is interrupted, the OFF-delay starts. When ti-ming is complete, the output relay de-energizes.

If supply voltage is re-applied to A1-A2/B1, before the time delay is complete, the time delay is reset and the output relay remains ener-gized.

Supply voltage must be applied for the minimum energizing time (200 ms), for proper operation.

E Impulse-OFF, with auxiliary voltage (Trailing edge interval) CT-AWE

This function requires continuous supply voltage at terminals A1-A2. Opening control contact A1-Y1, energizes the output relay immedia-tely and timing begins. When the selected time delay is complete, the output relay de-energizes.

Interrupting supply voltage or closing control contact A1-Y1, before the time delay is complete, de-energizes the output relay and resets the time delay.

E Impulse-OFF, without auxiliary voltage (True trailing edge interval) CT-AWE

The Impulse-OFF function without auxiliary voltage does not require supply voltage at terminals A1-A2 for timing.

If supply voltage is interrupted, the output relay energizes and the OFF time starts. When timing is complete, the output relay de-ener-gizes.

If supply voltage is re-applied to A1-A2, before the time delay is complete, the time delay is reset and the output relay de-energizes. Supply voltage must be applied for the minimum energizing time (200 ms), for proper operation.

F Flasher starting with ON (Recycling equal times, ON fi rst) CT-MFE

Applying supply voltage to terminals A1-A2, starts timing with sym-metrical ON & OFF times. The cycle starts with an ON time fi rst.

K Switching relay CT-IRE

The switching relay may be used to increase the number of available contacts or to reinforce contacts, or as a coupling/decoupling inter-face.

Applying supply voltage to terminals A1-A2, energizes the output re-lay. The output relay de-energizes if supply voltage is interrupted.

L Pulse former (Single shot) CT-MFE

Closing the control contact connected to terminals A1-Y1, with sup-ply voltage applied, energizes the output relay for the selected ON time. When the ON time is complete, the output relay de-energizes. Operating the control contact switch A1-Y1 during the time delay has no effect.

After the time delay is complete, it can be restarted by closing control contact A1-Y1.

If supply voltage is interrupted during timing, the output relay de-en-ergizes and the ON time is reset.

Electronic timersCT-E range with solid-state outputFunction diagrams

t = adjusted delay time




A ON-delay (Delay on make) CT-EKE

Timing begins when supply voltage is applied to terminal A1 and the load connected in series with AL. When the selected time delay is complete, the load energizes. The green LED glows as long as the load is energized.

If supply voltage is interrupted, the load de-energizes and the time delay is reset.

Interrupting supply voltage before the time delay is complete, resets the time delay. The load does not energize.


B OFF-delay, with auxiliary voltage (Delay on break) CT-AKE

The OFF-delay function with auxiliary voltage requires continuous supply voltage at terminal A1 and the load connected in series with AL, for timing.

Timing is controlled by a voltage-related (wet/non-fl oating) control contact, connected to terminals Y2-A2. When the control contact closes, the load energizes. If the control contact opens, the selected time delay starts (minimum control pulse length is 20 ms). The green LED glows as long as the load is energized.

When the selected time delay is complete, the load de-energizes.

If control contact Y2-A2 closes before the time delay is complete, the time delay is reset and the load remains energized. Timing starts again when the control contact re-opens.

Interrupting supply voltage resets the time delay and de-energizes the load.


Multifunction timer CT-MKE

Functions and time ranges are programmed by simply plugging in external wire jumpers.

Notice:

CT-...KE are solid-state timers with thyristor output for 2-wire applications. They are connected directly in series with the control coil of con-tactors or relays. Voltage should not be applied without a load connected, because there is no current limiting in the unit.

A ON-delay (Delay on Make)Without external connection. Timing begins when supply voltage is applied to terminal A1 and the load connected in series A2. When the selected time delay is complete, the load connected to A1-A2 energizes. If supply voltage is inter-rupted, the load de-energizes and the time delay is reset. Interrupting supply voltage before the time delay is complete, resets the time delay. The load does not energize.

D Impulse-ON (Interval)External connection X1-X4 required. The load energizes and timing starts when supply voltage is applied to terminal A1 and the load connected in series with A2. When the selected time delay is complete, the load de-energizes. Interrup-ting supply voltage before the time delay is complete, de-energizes the load and resets the time delay.

F Flasher, starting with ONExternal connection X1-X4 and X2-X4 required. When supply voltage is applied to terminal A1 and the load connected in series with A2, the load energizes and de-energizes with the selected ON & OFF times. The ON & OFF times are equal. The cycle starts with an ON time fi rst (load energized). If supply voltage is inter-rupted, the load de-energizes and the time delay is reset.

G Flasher, starting with OFFExternal connection X2-X4 required. When supply voltage is applied to terminal A1 and the load connected in series with A2, the load energizes and de-ener-gizes with the selected ON & OFF times. The ON & OFF times are equal. The cycle starts with an OFF time fi rst (load de-energized). If supply voltage is inter-rupted, the load de-energizes and the time delay is reset.

Electronic timersCT-S rangeFunction diagrams

A ON-delay (delay on make) CT-ERS, CT-MBS, CT-MFS, CT-MVSIf control contact Y1-Z2 is open, the timer is started as soon as the supply voltage is applied. The green LED fl ashes while timing. After the adjusted delay time has elapsed, the output relay is energized and the fl ashing LED turns stea-dy. If the supply voltage is interrupted, the output relay resets and the elapsed time is reset. Timing can also be started by opening control contact Y1-Z2 with the supply voltage applied.If control contact Y1-Z2 closes after the supply voltage has been applied, all the internal functions are reset. By closing control contact X1-Z2 the timer can be stopped. The elapsed time is stored. Timing continues if the contact is ope-ned again. This can be repeated as often as required.By setting the sliding switch to position Inst., the 2nd c/o contact operates im-mediately when the supply voltage is applied and the timer starts. If the supply voltage is disconnected, both c/o contacts reset.By connecting a remote potentiometer to the terminals Z1-Z2 the time can be adjusted externally. The internal potentiometer is automatically switched off, if an external potentiometer is connected.

B OFF-delay (delay on break) - volt-free (dry) control input CT-AHS, CT-MBS, CT-MFSThis function requires continuous supply voltage at the terminals A1/ B1/ B2-A2 for timing.Timing is controlled by a volt-free (dry) contact at the terminals Y1-Z2. If the contact is closed, the output relay is energized. If the contact is opened, the adjusted time starts to elapse (minimum control pulse length: 20 ms). The green LED fl ashes while timing. The LED turns steady and the output relay is de-energized if the timer has elapsed.The timer can be stopped by closing control contact X1-Z2 . The elapsed time is stored. Timing continues if the contact is opened again. This can be repeated as often as required.By setting the sliding switch to position Inst., the 2nd c/o contact operates immediately when the supply voltage is applied and the timer starts. If the supply voltage is disconnected, both c/o contacts reset.By connecting a remote potentiometer to the terminals Z1-Z2 the time can be adjusted externally. The internal potentiometer is automatically switched off, if an external potentiometer is connected.

B OFF-delay (delay on break) - voltage-related control input CT-APS, CT-MVSThe OFF-delay time relay CT-APS and CT-MVS require continuous supply voltage at the terminals A1/A3/A4/B1/B2-A2 respectively.Timing is controlled by a voltage-related (e.g. A1) contact at terminal Y1. If the control contact is closed the output relay is energized. If the control contact is opened, the adjusted time starts to elapse (minimum control pulse length 20 ms). The green LED fl ashes while timing. The LED turns steady and the output relay is de-energized if the timer has elapsed.By setting the sliding switch to position Inst., the 2nd c/o contact operates im-mediately when the supply voltage is applied and the timer starts. If the supply voltage is disconnected, both c/o contacts reset .

B OFF-delay (true delay on break) - without auxiliary voltage CT-ARSCT-ARS is an OFF-delay timer which does not require supply voltageat the terminals A1-A2 while timing.After a storage time of several months, a charging time of about 5 minutes is necessary. For this, voltage must be applied to the unit. After applying voltage, the output relay is energized and after disconnecting the supply voltage, the preset time starts to elapse.By connecting a remote potentiometer to the terminals Z1-Z2, the time can be set externally. When connecting a remote potentiometer, the factory-mounted jumper on the terminals Z1-Z2 has to be removed and the internal potentiometer has to be set to the lowest possible value.For correct function of the unit, it is necessary to observe the minimum energizing time. As soon as the timer starts to elapse, both LEDs will turn off.

C Symmetrical ON- and OFF-delay CT-EASThe time relay requires continuous supply voltage at the terminals A1/B1/B2- A2 respectively.The ON- and OFF-delay times of CT-EAS are symmetrical. The ON-delay function starts when control contact Y1-Z2 closes. The OFF-delay is started after the timer has elapsed and after control contact Y1-Z2 is opened.The green LED fl ashes during timing of both functions.If the sliding switch is set to the "Inst." position, the 2nd c/o contact is energi-zed immediately and the 1st change-over contact is energized after the delay time has elapsed.Both c/o contacts reset if the supply voltage is disconnected.

H Single pulse generator (Delay on make interval) CT-PGSWhen applying the supply voltage to A1/B1/B2-A2, the output relay is energized after the preset delay on operate time and de-energized after the delay on release time has elapsed. Timing can be stopped by closing control contact X1-Z2. When opening the contact again, the timer will continue at the stored time value.If the supply voltage is applied, timing can also be started by opening the control contact Y1-Z2. If control contact Y1-Z2 is closed after the supply voltage is applied, the internal function is reset.With the CT-PGS, a single pulse can be processed with delay.

H Pulse generator (Recycling unequal times) CT-TGSON and OFF times ranging from 50 ms to 300 h can be set independently of each other. Time ranges are set using two rotary switches. The desired time values are adjusted using built-in potentiometers with direct reading scales. Remote adjustment can be performed via two remote potentiometers.The internal potentiometers are switched off automatically when remote po-tentiometers are connected. The function can be changed from "OFF" starting cycle to "ON" starting cycle by means of an external connection between the terminals X2-Z2. The assignment of the internal and external potentiometers remains unchanged.By closing control contact X1-Z2, the timer for the ON/OFF cycle can be stopped. The elapsed time value is stored. By opening the contact again, the timer continues timing from this point. This function can be repeated as often as required. After applying the supply voltage to A1/B1/B2-A2, the CT-TGS starts to work with an "ON" cycle or an "OFF" cycle, as selected. The "ON"/ "OFF" cycles are displayed by the fl ashing green LED.

n = 1, 2 or 3

K Switching relay CT-IRS

The switching relay may be used to increase the number of available contacts or to reinforce contacts, or as a coupling/decoupling inter-face.If the supply voltage is applied to the terminals A1-A2, the output relay is energized after approx. 10 ms.If the supply voltage is interrupted, the output relay is de-energized.

J Star-delta change-over with impulse CT-YDEW, CT-MFS, CT-MBS, CT-MVS

The CT-YDEW and the function J of the multifunction timer CT-MFS, CT-MBS, CT-MVS respectively, is designed especially for star-delta starting of squirrel cage motors. It uses two separate timing circuits: a variable timing circuit for the starting time in star-mode, and a fi xed timing circuit with 50 ms for the transition from the star to the delta contactor. The fi rst output relay is energized after the supply voltage is applied to the terminals A1/A3/A4/B1/B2-A2. After the star time has elapsed, the fi rst output is de-energized and the second timer with 50 ms starts. After this timer has elapsed, the second output relay is energized and stays energized until the supply is disconnected. Timing is displayed by the fl ashing green LED.

t1 = adjustable starting timet2 = transition time (approx. 50 ms)
