Description:
1. The signal triggers the relay to pick up. When the time is up, the relay is disconnected. During the delay period
a: re-trigger invalid B: re-trigger re-timing C: re-trigger relay reset termination timing
2. Signal trigger start timing time T1, time to relay pick-up time T2 disconnect (reset) the time of T1 and T2 is adjustable
3. Cyclic use: connect T1, disconnect T2, infinite cycle. The time of T1 and T2 is adjustable
4. If there is a signal, the relay will pick up and keep picking up. The signal will disappear and start timing. When the time is up, the relay will be disconnected. During the delay period, the signal will be sent again. The delay will be canceled and the signal will disappear, re-clocking.
relay snap-in, often start to connect with the public end, often close to disconnect with the public end; selection of working mode: after the power is turned on, press K1 for 2 seconds to enter the selection function mode.
P1-1~P1-4 can be selected, P1-1 working mode: signal trigger relay pick-up, time is up, relay is disconnected. The user can set the pick-up time T of the relay, press K2 100-digit digital tube to start flashing, then press K3 to change the 100-digit digital tube; Press K2 10-digit digital tube to start flashing, then press K3, ten digit change; Press K2 digit digital tube to start flashing, then press K3 to change digit number; Press K2 again; The digital tube will not flicker, then press K3, XIAOSHUDIAN shift, XIAOSHUDIAN indicates 0 to 999 minutes in individual bits and 0 to 99.9 seconds in ten bits. No XIAOSHUDIAN indicates 0 to 999 seconds. After you select it, the time is set. Press K1 briefly to enter the fine adjustment settings of the function. By default, the trigger during the delay period is invalid. Press K1, and the trigger during the delay period is valid (re-timed). Press K1, reset during delay (timing off, relay reset), press again to repeat the default setting for the first time.
P1-2 working mode: signal trigger start timing X time to relay snap Y disconnect. Users can set the pick-up time of the relay X,Y; The time setting class is similar to the P1-1 difference is that the blue light on indicates the pick-up time of the relay, and the blue light off indicates the turn-off time of the relay. Press K1 to enter the minor adjustment settings of the function. By default, the trigger during the delay period is invalid. Press K1, and the trigger during the delay period is valid (re-timed). Press again to repeat the default first setting.
P1-3 operation mode: turn on X seconds, turn off Y seconds, infinite cycle. The user can set the pick-up time of relay X,Y; The time setting class is like P1-2. Press K1 briefly to enter the fine adjustment settings of the function. Turn on X first, turn off Y seconds, press K1 once, turn off X First, turn on Y seconds,, click again to repeat the default first setting.
P1-4 working mode: the signal triggers the relay to pick up but does not start timing, the trigger signal disappears and starts timing T, when the time is up, the relay is disconnected; During the delay period, the signal is given again, and the delay is canceled, keep the snap, the signal disappears, and the timing starts again; (it is equivalent to releasing the button to start timing, which is often used for power failure delay). The user can set the pick-up time T of the relay; The time setting class is like P1-1.
