At the end of the first time period (T1), the relay operates. When the second time peri- od (T2) has expired, the relay releases. This sequence continues until power supply is interrupted for at least 200 ms. Connection between Y1-Y3 ON-time period first The relay operates and the time period begins when power supply is applied. At the end of the first time period (T1), the relay releases. When the second time peri od (T2) has expired, the relay op- erates. This sequence continues until power supply is interrupted for at least 200 ms. Connection between Y2-Y3 One shot time function The time period begins when power supply is applied. At the end of the first time period (T1), the relay operates. When the second time period (T2) has expired, the relay re- leases. The relay will stay OFF until power supply is interrupted for at least 200 ms, and the sequence will be repeated.
