Operation introduction:

1. In the non-setting state, short press the SET button, and the cycle display: working mode -> lower limit voltage -> upper limit voltage.

2. In the non-setting state, press the Changan SET key for 2 seconds to enter the parameter setting state; the display shows F01, press the +- key to select the parameter to be set, F01 (upper limit voltage), F02 (lower limit voltage), F03 working mode, F04 voltage calibration value.

3. After selecting the parameters to be set, short press the SET button to enter the parameter setting state, press the +- button to adjust, when the lower limit voltage is greater than or equal to the upper limit voltage, the display will display Err for 1 second to prompt the user. When the lower limit voltage is equal to the upper limit voltage, the relay output function is turned off.

4. After setting the parameter value, short press the SET key to return to the parameter list.

5. After setting the parameters, press and hold SET for 2 seconds to exit and save the parameters.

6. In the non-setting state, press and hold the SET and + keys for 2 seconds at the same time to restore the factory settings.

7 Long press - turn off or turn on the digital tube display energy saving mode

Detailed settings:

F03 working mode non-setting state

Long press SET to select F03 working mode selection, + and - to select the desired function, then long press SET to save and exit

Please note that before setting this parameter, please set the upper limit voltage and lower limit voltage as required

H-1, Charging monitoring When the monitoring voltage is lower than the lower limit voltage, the relay pulls in, and when it is higher than the upper limit voltage, it disconnects.

H-2, Discharge monitoring When the monitoring voltage is higher than the upper limit voltage, the relay pulls in, and when it is lower than the lower limit voltage, it disconnects.

H-3 Pull-in outside the interval When the monitoring voltage is between the upper limit voltage and the lower limit voltage, the relay is disconnected, and the relay is closed in other states

H-4 Pick-up in the interval When the monitoring voltage is between the upper limit voltage and the lower limit voltage, the relay picks up, and the other state relays are disconnected

H-5 Fixed-point monitoring When the monitoring voltage is higher than the lower limit voltage, the relay is closed, and the relay is disconnected when it is lower than the lower limit voltage

H-6 Fixed-point self-locking monitoring When the monitoring voltage is higher than the lower limit voltage, the relay will pick up and keep picking up until manual intervention or power failure

H-7 Fixed-point pulse monitoring When monitoring each time is equal to the lower limit voltage (±0.1V), the relay outputs a jog signal

F04 Calibration mode Long press the SET key to enter in the non-setting state, +- to select

The default is 0 error, if you need to set the adjustment on demand,

For example, the actual input voltage is 12.5v, and the module displays 12.4V. At this time, you can correct and set the error to 0.1V, that is, 12.4+0.1=12.5

For example, the actual input voltage is 12.5v, and the module displays 12.6V. At this time, you can correct and set the error to -0.1V, that is, 12.6-0.1=12.5

Note:

1. Due to the light and screen difference, the item's color may be slightly different from the pictures.

2. Please allow 1-3cm differences due to manual measurement.
