Time Delay Relays Dedicated - Recycle KSD3 SERIES Recycling Flasher Description The KSD3 Series Digi-Timer is a cost effective approach for ON/OFF recycling applications. The on time is equal to the off time. An adjustment of the R will change the time delays T of both on and off times. This series is designed for general purpose commercial and industrial applications where a small, cost effective, reliable, solid-state timer is required. The factory calibration for fixed time delays is within 5% of the target time delay. The repeat accuracy, under stable conditions, is 0.5% of the selected time delay. This series is designed for popular AC and DC voltages. Time delays of 0.1 seconds to 1000 minutes are available in 6 ranges. The output is rated 1A steady and 10A inrush. The modules are totally solid state and encapsulated to protect the electronic circuitry. Operation (Recycling Flasher - ON Time First) Upon application of input voltage, the output energizes and the T1, ON time begins. At the end of the ON time, the output de-energizes and the T2 OFF time begins. At the end of the OFF time, the output energizes and the cycle repeats as long as input voltage is applied. Wiring Diagram Reset: Removing input voltage resets the output and time delays, and returns the sequence to the ON time. Operation (Recycling Flasher - OFF Time First) L1 N/L2 Upon application of input voltage, the T2 OFF time begins. At the end of the OFF time, the T1 ON time begins and the load energizes. At the end of the ON time the load de-energizes, and the cycle repeats until input voltage is removed. V = Voltage Reset: Removing input voltage resets the output and time L = Load delays and the sequence to the OFF time. R is used when T external adjustment is ordered.

Function Diagrams The time delay is adjustable over the time delay range selected by varying the resistance across the R terminals as the resistance increases the tie T delay increases. FLASHER (ON FIRST) When selecting an external R , add the tolerances of the timer and the R T T for the full time range adjustment. Examples: 1 to 50 S adjustable time delay, select time delay range 1 and a 50 K ohn R . For 1 to 100 S use a 100 K ohm R .
