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:

Long press: keep pressing the button for more than 3second.

•  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.

UART communication and parameter settings:

The system supports UART data upload and parameter setting functions (TTL level);

UART: 9600, 8, 1

NO.	Command	Function
1	Read	Read the parameter setting
2	OP:XXXX	Set the minimum delay time for turn ON : 1s
3	OP:XXX.X	Set the minimum delay time for turn ON : 0.1s
4	OP:XX.XX	Set the minimum delay time for turn ON : 0.01s
5	OP:X.X.X.X	Set the minimum delay time for turn ON : 1min
6	CL:XXXX	Set the minimum delay time for turn OFF : 1s
7	CL:XXX.X	Set the minimum delay time for turn OFF : 0.1s
8	CL:XX.XX	Set the minimum delay time for turn OFF : 0.01s
9	CL:X.X.X.X	Set the minimum delay time for turn OFF : 1min
10	LP:XXXX	Number of cycles:1-9999
11	ON	Relays Enable

Additional Features:

1. Auto sleep function: Long press button ‘STOP’ in the normal running interface to turn on or off auto sleep function. L-P: ON, Turn ON auto sleep function. L-P: OFF, Turn OFF auto sleep function. 2. Relay function selection: Short press button ‘STOP’ in the normal running interface to turn on or off relay delay function. ‘ON’:Relay is normally turned on when the conduction condition is met. ‘OFF’:Relay is normally turned off even though the conduction condition is met. LCD will flash ‘OUT’ at the status of OFF. 3. View parameters: In the running interface, short press the SET button to display the current parameter settings of the system, which does not affect the normal operation of the system. 4. Switch the display content: It will switch the display content by short pressing the button ‘DOWN’ in the P5 or P6 model
