After the pull-in time T2 is reached, the relay is off, and then the above state is repeated. The X interface is high at any time. Pulse signal, this function resets and restarts operation;
Function 6: Infinite loop mode 2: When the power is turned on, the relay immediately pulls in. After the pickup time T1 arrives, the relay turns off. After the off time T2 arrives, the relay pulls in and then repeats the above state. Any time, the X interface is high. Flat pulse signal, this function resets and restarts operation;
Function 7: Limited Cycle Mode 1: When the power is turned on, the relay opens. After the off time T1 arrives, the relay pulls in. After the pull-in time T2 arrives, the relay turns off, and then repeats the action more than NX times. The cycle number NX is in the range of 1 - 9999. Adjustable between times, any time to a high level pulse signal to the X interface, this function reset and restart the operation;
Function 8: Limited Cycle Mode 2: When the power is on, the relay pulls in and the relay turns off after the pull-in time T1 arrives; the relay pulls up after the turn-off time T2 arrives, and then repeats the action more than NX times. The cycle number NX is in the range of 1-9999. Adjustable between times, any time to a high level pulse signal to the X interface, this function reset and restart the operation;
Function 9: Self-locking relay mode: A high-level pulse signal is sent to the relay X interface, the relay pulls in, and then a high-level pulse signal relay is turned off.
Function 10: Level-triggered relay mode (including delay disconnection function): When the power is turned on, the relay is disconnected, and a high-level signal is sent to the X interface, and the relay immediately pulls in. After the X port signal disappears, the relay still pulls in. After the pull-in time T1 is reached, the relay opens. Note: In this function, if T1 is set to 0 seconds, it will become: X port has high level signal relay to pull in, and if there is no signal, it will be disconnected immediately.
