DC+: Input DC power supply positive pole 2. DC-: Input DC power supply negative pole 3. IN+: Signal input positive pole 4. IN-: Signal input negative pole 5. NO: Relay normally open interface, the relay is suspended before the suction, and is short connected with COM after the suction 6. COM: Relay common interface 7. NC: The relay normally closed interface, and the relay is short connected with COM before the suction, suspended after the suction Button Trigger: Positive Trigger: DC- and in- short circuit, DC+ and IN+ connected to the button Or Negative Trigger: DC+ and in+ short circuit, DC- and IN- connected to the button Function list: P-11: Inching (give the signal relay suction, the signal disappears and the relay stops) P-12: Self-locking (give a signal and the relay pull in, then give a signal and the relay stop) P-13: Give the signal, the relay will stop automatically after A seconds suction; the trigger will be invalid during the delay. P-14: Give the signal, the relay will stop automatically after A seconds suction; trigger the retime during the delay. P-15: Give the signal, the relay will stop automatically after A seconds suction; trigger the superimposed timing during the delay. P-16: Give signal, the relay will stop automatically after A seconds suction; trigger reset during delay P-17: Give the signal, relay suction, the input signal is disconnected, the power is turned off after A seconds time counting, and the signal is kept output again during the delay. P-18: After power-on, the relay will immediately pull in, after a delay of A seconds, the power will be turned off until next time power on. P-21: Give the signal, after a delay of A seconds, the relay pulls in P-22: Give signal, after more than A seconds, the relay pulls in, the signal disappears, the relay stops. P-23: After the signal disappears for more than A seconds, the relay pulls in, there is a signal, and the relay stops. P-24: There is a signal. After more than A seconds, the relay pulls in. After the signal disappears for more than A seconds, the relay stops. P-25: There is a signal. After more than A seconds, the relay pulls in, and after having a signal again for A seconds, the relay stops. P-26: There is a signal. The relay stops after A seconds of suction. The signal disappears and the relay will pull in again for A seconds, then stop. P-27: The pulse signal is detected, the relay stops; if there is no pulse signal, the relay delays for A seconds before suction; (continuous signal or signal disappearance is regarded as no pulse signal) P-28: After power-on, after a delay of A seconds, the relay pulls in until the power is turned off. P-31: After power-on, the relay pulls in for A seconds, disconnected for B seconds, infinite loop and it won't stop until power off; P-32: There is a signal, start P-31 infinite loop; when signal disappears, terminate loop P-33: Give a signal, start P-31 infinite loop; give another signal to terminate the loop P-34: After power-on, after a delay of A seconds, the relay pulls in, after B seconds of suction, the relay stops. P-35: There is a signal. After a delay of A seconds, the relay pulls in, after B seconds of suction, the relay stops.. P-36: There is a signal. After more than A seconds, the relay pulls in, stops after B seconds of suction, the signal disappears, and the timing is cleared. P-37: There is a signal, the relay will stop automatically after A seconds of suction, timed for B seconds after stopping. The signal trigger is invalid during A+B time. P-38: There is a signal, the relay will stop automatically after A seconds of suction, timed for B seconds after stoping, and then automatically stops after A seconds of suction . P-41: No action when there is a signal, triggers signal disappears; the relay works after A time delay and then disconnected. P-42: The signal disappears, after a delay of A time, the relay works; it ends at working B time P-43: The signal disappears. After A time, the relay works; it ends at working B time P-44: After power-on, the relay works for A time and stops B time; it automatically stops after C times cycle. P-45: No action when the power is on and after the signal is given; the relay works for A time, stops for B time; it
