They operate over a 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 For the CT-BS version with a - AC supply voltage, the time delay is selected by connecting terminal to. When jumpered, the time delay is from to s. If terminals - are not jumpered, the time delay is from to ms. The exact time delays can be seen in the delay time diagrams. Function diagrams B OFF-delay without auxiliary voltage (True delay on break) The DC contactor connected to the output is energized when supply voltage is applied to terminals A- A. If supply voltage is disconnected, the DC contactor remains energized for a short time delay. This delay time depends on the coil drop out voltage and on the wattage of the contactor coil.
