Functions Operating controls Rotary switch for the preselection of the time range Fine adjustment of the time delay CDC 00 V00 Indication of operational states U/T: green LED control supply voltage / timing R: yellow LED - status of output relay R: yellow LED - status of output relay Marker label 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 to 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 FC Star delta change over with impulse 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 7-8 7-8 green LED t t t = adjusted starting time t = transition time (0 ms) CDC 00 F00 Electrical connection 7 7 8 st n/o contact 7 8 nd n/o contact 7 A Rated control supply voltage U S 80-0 V AC A 8 8 8 8 A CDC 0 F0b0 Connection diagram - Electronic timer CT-SDS.
