Working Mode:

• P1:Relay will keep ON for time OP after getting the trigger signal and then relay OFF; The input signal is invalid if get trigger signal again during delay time OP.
• P2:Relay will keep ON for time OP after getting trigger signal and then relay OFF; Module will restart-delay if get trigger signal again during delay time OP.
• P3:Relay will keep ON for time OP after getting the trigger signal and then relay OFF; Module will reset and stop timing if get trigger signal again during delay time OP.
• P4:Relay will keep OFF for time CL after getting trigger signal and then relay keep ON for time OP and then the relay will OFF.
• P5:Relay will keep ON for time OP after getting the trigger signal and then relay keep OFF for time CL and then loops the above action. The module will reset and stop timing and relay OFF if get a trigger signal again during loops. The number of cycles (LOP) can be set.
• P6:Relay will keep ON for time OP after power on without getting trigger signal and then relay keep OFF for time CL and then loops the above action. The number of cycles (LOP) can be set.
• P7:Signal hold function. Reset delay time and relay keep ON if keep getting trigger signal. Relay OFF when the signal disappears. Reset delay time when getting trigger signal again during timing.

Timing Range:

• Continuously adjustable from 0.01 seconds to 9999 minutes.
• Enter the settings interface when short press button STOP in the OP / CL parameter modification interface(Flashing) to select timing range.
• Pay attention to the position where the decimal point moves when the button is pressed.
• Display XXXX.No decimal point, the timing range is 1 second ~ 9999 seconds.
• Display XXX.X.The decimal point is the penultimate, timing range is 0.1 second to 999.9 seconds.
• Display XX.XX.The decimal point is the third last, timing range is 0.01 second to 99.99 seconds.
• Display X.X.X.X.The decimal point is fully lit, timing range is 1 minute to 9999 minutes.
• For example, if you want to set the OP to 3.2 seconds, move the decimal point to the penultimate position, LCD will display 003.2.

Parameter Description:

• OP: Turn On-time;
• CL: Turn OFF time;
• LOP: Number of cycles.The range is 1-9999tims.- means unlimited loop.

Set Parameter:

• Enter set parameter menu by long press button SET.
• Work mode will flash at first set the working mode. Short press the UP/DOWN button to set the working mode.
• Short press the SET button to select the working mode and enter the system parameter settings.
• In the system parameter setting interface, short press the SET button to switch the system parameters to be modified, short/long-press the UP/DOWN button to modify value;
• Note: Short press SET is invalid at mode P1,P2,P3,P7.
• Enter setting interface when short press button STOP in the OP/CL parameter modification interface(Flashing) to select timing range (1s/0.1s/0.01s/1min).
• Save the parameter settings and exit the settings interface when long-press the SET button after all the parameters are set.
