Operating the control contact switch A1-Y1/B1 duringthe time delay has no effect. The green LED flashes during timing. Whenthe selected ON time is complete, the output relay de-energizes and theflashing green LED turns steady. After the ON time is complete, it can berestarted by closing control input A1-Y1/B1. If control supply voltage isinterrupted, the output relay de-energizes and the time delay is reset.Pulse generator, starting with the ON or OFF time(Recycling unequal times, ON or OFF first)CT-TGDThis function requires continuous control supply voltage for timing.Applying control supply voltage, with open control input A1-Y1/B1,starts timing with an ON time first. Applying control supply voltage, withclosed control input A1-Y1/B1, starts timing with an OFF time first. TheON & OFF times are displayed by the flashing green LED, which flashestwice as fast during the OFF time. The ON & OFF times are independentlyadjustable. If control supply voltage is interrupted, the output relayde-energizes and the time delay is reset.A1-A2A1-Y1/B115-18, 25-2815-16, 25-26green LEDtt2CDC 252 110 F0206A1-A2A1-Y1/B115-18, 25-2815-16, 25-26green LEDt 1 t 2 t 2t 12CDC 252 111 F0206t = adjusted pulse timet 1 = adjusted OFF timet 2 = adjusted ON time6Star-delta change-over(Star-delta starting)CT-SDD, CT-SADThis function requires continuous control supply voltage for timing.Applying control supply voltage to terminals A1-A2, energizes the starcontactor connected to terminals 17-18 and begins the set startingtime t 1. The green LED flashes during timing. When the starting time iscomplete, the first output contact de-energizes the star contactor.Now, the transition time t 2starts. When the transition time is complete,the second output contact energizes the delta contactor connected toterminals 17-28. The delta contactor remains energized as long ascontrol supply voltage is applied to the unit.A1-A217-1817-28green LEDt 1 t 2t 1 = adjusted starting timet 2 = transition timeCT-SDD: t2 = 50 msCT-SAD: t 2 adjustable2CDC 252 112 F0206L1F3F2S10959621222CDC 252 128 F0b06L1 L2 L31 3 5-F12 4 62CDC 252 012 F0b07IS213K214K1T535417181728K21314K11314-K2123456-K3123456-K1123456K32221K12221-F213524697989596A1A1A1A1K1T K1 K3 K2A2A2A2A2NY NControl circuit diagramW1V1U1-M1M3 ~Power circuit diagramW2V2U26/48ABB
