Application

The CT-S range timers are designed for use in industrial applications. They operate over a universal range of supply voltages and a large time delay range, within compact dimensions. The easy-to-set front-face potentiometers, with direct reading scales, provide accurate time delay adjustment.

Multifunction timers are ideally suited for service and maintenance applications, because one device can replace a number of time relays with different functions, voltage and time ranges. This reduces inventory and saves money.

Operating mode

The CT-MFS with 2 c/o contacts provides 8 timing functions. The function is rotary witch selectable on the front of the unit. Each function is indicated by an international function symbol. One of 10 time delay ranges, from 0.05 s to 300 h, can be selected with another rotary switch. The fine adjustment of the time delay is made via an internal potentiometer, with a direct reading scale, on the front of the unit. When an external potentiometer is connected to terminals Z1- Z2, the internal adjust-ment is disabled and external adjustment is enabled. Timing is displayed by a flashing green LED labelled U/T.

Function diagrams

A ON-delay (delay on make)

If control contact Y1-Z2 is open, timing begins when supply voltage is applied to A1-A2. Or, if supply voltage is already applied, opening control contact Y1-Z2 also starts timing. The green LED flashes during timing. When the selected time delay is complete, the output relays energi-ze and the flashing green LED turns steady. If supply voltage is interrupted, the output relays de-energize and the time delay is reset. If control contact Y1-Z2 closes before the time delay is complete, the time delay is reset and the output relays remain de-energized. Timing can be paused by closing control contact X1-Z2. The elapsed time is stored and continues from this time value when X1-Z2 is re-pened. This can be repeated as often as required. When an external potentiometer is connected to terminals Z1-Z2, the internal, front-face potentiometer is disabled and the time adjustment is made via the external potentiometer. If the front-face sliding switch is set to the “Inst.” position, the 2nd c/o contact energizes immediately upon application of the supply voltage.

BOFF-delay (Delay on break)

This function requires continuous supply voltage at terminals A1-A2 for timing. Timing is controlled by a volt-free control contact, connected to terminals Y1-Z2. If the control contact is closed, the output relays energize. If the control contact is opened, the selected time delay starts (minimum control pulse length is 20 ms). The green LED flashes during timing. When the time delay is complete, the output relays de-energize and the flashing green LED turns steady. If control contact Y1-Z2 closes before the time delay is complete, the time delay is reset and the output relays remain energized. Timing can be paused by closing control contact X1-Z2. The elapsed time is stored and continues from this time value when X1-Z2 is re-opened. This can be repeated as often as required. When an external potentiometer is connected to terminals Z1-Z2, the internal, front-face potentiometer is disabled and the time adjustment is made via the external potentiometer. If the front-face sliding switch is set to the “Inst.” position, the 2nd c/o contact energizes immediately upon application of the supply voltage.

D Impulse-ON (Interval)

The output relays energize immediately when the supply voltage is applied to terminals A1-A2 and de-energize after the set pulse time is complete. The green LED flashes during timing. When the selected pulse time is complete, the flashing green LED turns steady. Timing can be started by opening control contact Y1-Z2, with supply voltage applied. Closing control contact Y1-Z2, before the time delay is complete, de-energizes the output relays and the time delay is reset. Timing can be paused by closing control contact X1-Z2. The elapsed time is stored and continues from this time value when X1-Z2 is re-opened. This can be repeated as often as required. When an external potentiometer is connected to terminals Z1-Z2, the internal, front-face potentiometer is disabled and the time adjustment is made via the external potentiometer. If the front-face sliding switch is set to the “Inst.” position, the 2nd c/o contact energizes immediately upon application of the supply voltage.

E Impulse-OFF (Trailing edge interval)

This function requires continuous supply voltage at terminals A1-A2. Opening control contact Y1-Z2, energizes the output relays immediately and timing begins. The green LED flashes during timing. When the selected pulse time is complete, the flashing green LED turns steady and the output relays de-ener-gize. Closing control contact Y1-Z2, before the time delay is complete, de-energizes the output relays and the time delay is reset. Timing can be paused by closing control contact X1-Z2.

F Flasher with symmetrical ON & OFF times, starting with the ON time (Recycling equal times, ON first)

Applying supply voltage to terminals A1-A2, starts timing with symmetrical ON & OFF times. The cycle starts with an ON time first. The ON & OFF times are displayed by the flashing green LED, which flashes twice as fast during the OFF time. Closing control contact Y1-Z2, with supply voltage applied, de-energizes the output relays. Opening control contact Y1-Z2, starts the timer pulsing again with the set cycle. When an external potentiometer is connected to terminals Z1-Z2, the internal, front-face potentiometer is disabled and the time adjustment is made via the external potentiometer. If the front-face sliding switch is set to the “Inst.” position, the 2nd c/o contact energizes immediately upon application of the supply voltage.

I Star-delta change-over, twice ON-delayed (Star-delta starting, delay on make / delay on make)

Applying supply voltage to terminals A1-A2, energizes the star contactor connected to terminals 15-16 and begins the set starting time. The green LED flashes during timing. When the starting time is complete, the first c/o contact de-energizes the star contactor. Now, the fix transition time of 50 ms starts. When the transition time is complete, the second output relay energizes the delta contactor connected to terminals 25-28. The delta contactor remains energized as long as the supply voltage is applied to the unit. The “Inst” sliding switch (to set the 2nd c/o contact as an instantaneous contact) is disabled when this function is selected.
