Instruction Manual
The multifunctional relay control module (FRM02), uses an internal microcontroller as the main control unit and includes 18 preset types of functions.
These modes can be customized based on user requirements. The two relays can be programmed separately and independently.

II. Setting the operation modes

The user can set the operation mode by using the keys and the display. All parameters are automatically saved after setting.

Keys: there are 4 keys, namely: [SET] [SM1], [NUM +] and [NUM-],
The keys recognize short and long press.

Short press means you press the key for less than 1 second.
Long press means you press the key for more than 1 second.

Operating mode: there are 3 types, namely: [Operating mode], [Parameter view
mode] and [Parameterization mode].

[Digital displays]: There are 4 digital displays which are used to set or view user timing

[LED]: 4 blue parameter indicators, 1 red operation indicator on the power connector.

[User Parameters]:
There are 4 types of parameters that can be set (4 blue LED lights).

[MD]: MD, display shows the current program mode. There are 18 modes in total to choose from (01-18).

[T1]: T1 LED, display shows time T1, can be 0-9999 seconds.

[T2]: T2 LED, display shows time T2, can be 0-9999 seconds.

[NX]: NX-LED, display shows the different meanings depending on the function.

1. NX meaning

In functions 1-6 and 11-16, NX-LED in display shows the time base.
Time base means that the numerical values entered in T1 and T2 are multiplied by the values in the NX indication.

For example: NX displays "01 01".
This means that the timing time unit is 1 second.

For example: NX displays "10 02".
This means that the timing time unit of T1 is 10 seconds, T2 is 2 seconds.
The value 10 is then multiplied by the value of T1 to calculate the timer T1.
The value 2 is then multiplied by the value of T2 to calculate the timer T2.

The maximum time can be set by this multiplication as 9999 (T1) x 99 (NX) seconds, which is approximately 270 hours.

2. NX Meaning
In functions 7, 8, 17, and 18, the NX value on the display indicates how many cycles to run in that mode.

In these modes, the times for T1 and T2 cannot be multiplied by the "NX" value.

Operating mode

1. When the module is switched on, a short countdown starts. After that, the current function number is displayed.

Example: (1 - 0 1 ) means "relay no.1 with function01.

Example: (2 - 0 1 ) means "Relay No.2 with function01.

2. Press [SET] briefly to enter the power saving mode, the display will go out, but the program will continue to work normally. Press [SET] again to restore the display.

3. Long press [SET] to enter the parameter setting mode.

4. Long press [SWI] to enter the parameter view mode.

5. Long press [NUM+] to enter the automatic power saving mode of 10 seconds.
The display will blink twice, which means that the setting was successful. After entering the power saving mode, if no key is pressed within 10 seconds, the display will turn off, but the program will continue to run.
You can also long press [NUM+] again to exit the automatic mode.

6. Long press [NUM-] to reset the timing and stop. Press [NUM-] again briefly to restore the timing. After resetting, the LED lights will stop flashing.

Parameter view mode

Long press [SWI] to enter the parameter view mode. This mode, can display the parameters of the current function
Short press [SET] key to switch parameters.
Long press [SM1] key to enter [Operation Mode];

Parameter setting mode
Long press [SET] to enter parameter setting mode. In this mode, you can set various parameters, for example, you can set mode 1 to 18 and times T1 and T2 and NX.

1. Press [SET] button briefly to switch parameters, you can select one from [MD] (mode 1-18). [T1], [T2] or [NX], the LED indicator of the selected parameter will show on the display the set parameters.

2. Briefly press the [SWI] button to go to the setting of time T1, the blue LED with the inscription T1 will now light up as a check.
Set the desired time here using the SM1, NUM+ and NUM- buttons.

3. Briefly press the [SWI] key to go to the setting of time T2, the blue LED with the inscription T2 now lights up as a check.
Set the desired time here using the SM1, NUM+ and NUM- keys.

4. Briefly press the [SWI] key to go to the setting of the time NX, the blue LED with the inscription NX will now light up as a check.
Set the desired numbers here using the SM1, NUM+ and NUM- keys.

5. Long press the [SET] key, save the parameters and enter the operating mode.

Example1
Control a lamp to be automatically on for one hour via relay no.1 and then turn it off.

This application can use mode2 or mode12:

MOD="1 - 12"
T1=3600
T1="xxxx" (not needed)
NX="0 1 x x "(x can be any value, no need)

Procedure:
1. Long press [SET] to enter parameter setting mode;
2. MOD LED is on, press [NUM+] or [NUM-] and set the following on the display "1 - 12". (This corresponds to mode 12)
3. Briefly press "SET", T1 LED lights up. Now set by display = "3 6 0 0". T2 is not required.
4. Short press "SET" and set at NX="0 1 0 1"
5. Long press [SET], save the settings and exit the parameter setting mode. The function starts immediately.

Example2
When the machine is switched on, it runs for one hour via relay2, then stops for 10 minutes and repeats this for 5 cycles. The machine then switches off.

This application can be implemented with mode8.

Parameter:
MOD="2 - 0 8"
T1="3 6 0 0"
T2="0 6 0 0"
NX="0 0 5"

III. Wiring
Recommendation:
1. Separate wiring for power supply of the timing relay module and the voltage to be switched.
2. Select a generously dimensioned voltage source with regard to the current strength in order to reduce current fluctuations.
3. Capacitor: If the above two measures do not achieve the desired effect, you can connect an electrolytic capacitor with a capacitance of 470 uf/35 V or more between DC- and DC +.
