2 Application The CT S range timers are designed for use in industrial applications. They operate over an 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. Operating mode The CT SDS. has n/o contacts and includes separated timing circuits: an adjustable motor starting delay, the time the star contactor is energized, and an 0 ms fixed open transition delay before the delta contactor is energized. A rotary switch, on the front of the unit, allows selection of one of 7 time ranges from 0.0 s 0 min. The fine adjustment of the time delay is made via an internal potentiometer, with a direct reading scale, on the front of the unit. Timing is displayed by a flashing green LED labelled U/T. Function diagram Remarks Legend: G Control supply voltage not applied / Output contact open B Control supply voltage applied / Output contact closed Terminal designations on the device and in the diagrams: The st n/o contact is designated 7 8. The nd n/o contact is designated 7 8. Control supply voltage is applied to terminals A A. Function of the yellow LEDs: The two yellow LEDs are designated R and R. LED R shows the status of the st n/o contact (7 8) and LED R shows the status of the nd n/o contact (7 8). LED R or R glows as soon as the corresponding output relay energizes and turns off when the corresponding output relay de energizes. F Star delta change over This function requires continuous control supply voltage for timing. Applying control supply voltage to terminals A A, energizes the star contactor connected to terminals 7 8 and begins the set starting time t. The green LED flashes during timing. When the starting time is complete, the first output contact de energizes the star contactor. Now, the fixed transition time t of 0 ms starts. When the transition time is complete, the second output contact energizes the delta contactor connected to terminals 7 8. The delta contactor remains energized as long as control supply voltage is applied to the unit. A-A green LED t t t = adjusted starting time t = transition time (0 ms) CDC 00 F00
