Data sheet Electronic timer CT-SDD. Star-delta change-over with n/o contacts The CT-SDD. is an electronic time relay with star-delta change-over. It is from the CT-D range. With their MDRC profile and a width of only 7. mm, the CT-D range timers are ideally suited for installation in distribution panels as well as for industrial applications where compact dimensions are required. CDC 099 F000 Characteristics Rated control supply voltage 8 V DC, 0 V AC Single function timer star delta change over time ranges (0.0 s 0 min) in one device Light grey enclosure in RAL 70 n/o contacts Width of only 7. mm (0.89 in) LEDs for the indication of operational states Approvals A UL 08, CAN/CSA C. No. R E Marks a EAC CCC CE b RCM Order data Type Rated control supply voltage Time range Output Order code CT-SDD. 8 V DC, 0 V AC 0.0 s 00 h n/o contacts SVR 00 R000
Functions Operating controls Rotary switch for the preselection of the time range Potentiometer with direct reading scale for the fine adjustment of the time delay Indication of operational states U: green LED V control supply voltage applied W timing R: yellow LED V output relay energized R: yellow LED V output relay energized Circuit diagram CDC 099 F000 Application With their structural form and their width of only 7. mm, the CT D range timers are ideally suited for installation in distribution panels. Operating mode The CT SDD. has n/o contacts and offers time ranges, from 0.0 s to 0 min, for the adjustment of the starting time. The time delay range is rotary switch selectable on the front of the unit. The fine adjustment of the time delay is made via an internal potentiometer, with a direct reading scale, on the front of the unit. - Electronic timer CT-SDD. Data sheet
Function descriptions / diagrams 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 transition time t 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 fix 0 ms CDC 0 F007 Examples of application Star delta change over L F L L L F S 0 9 9 -F I S K KT 7 8 7 8 K K -K -K -K K K -F 97 98 9 9 N KT A K K K A A A Y N CDC 8 F0b0 W V U -M M ~ W V U CDC 009 F00 Control circuit diagram Power circuit diagram Electrical connection A Rated control supply voltage U s 8 V DC or 0 V AC 7 7 8 st n/o contact 7 8 nd n/o contact 7 A 8 8 8 8 A CDC 0 F0b0 Connection diagram Data sheet Electronic timer CT-SDD. -
