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. 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, 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 green LED t t t = adjusted starting time t = transition time (0 ms) CDC 00 F00
