DC 12V Voltage Detection Battery Charging Discharge Monitor Relay Switch Module

product description:
 
1. In the non-setting state, short press the SET key to 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 parameter that needs to be set, short press the SET button to enter the parameter setting state, and press the +- button to adjust. When the lower limit voltage is greater than or equal to the upper limit voltage, the display shows 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, long press SET for 2 seconds to exit and save the parameters.
 
6. In the non-setting state, press and hold the SET and + keys at the same time for 2 seconds to restore the factory settings.
 
7 Long press-turn off or turn on the digital tube to display the energy-saving mode
 
Detailed setting:
 
F03 working mode not set state
Long press SET to select F03 work mode selection, + and-to select the required function, then long press SET to save and exit
Need to pay attention to before setting this parameter, please set the upper limit voltage and lower limit voltage according to your needs
 
H-1, charge monitoring. When the monitoring voltage is lower than the lower limit voltage, the relay is switched on, and the voltage higher than the upper limit is disconnected.
 
H-2, discharge monitoring. When the monitoring voltage is higher than the upper limit voltage, the relay is closed, and when the monitoring voltage is lower than the lower limit voltage, it is disconnected.
 
H-3 pull-in outside the interval. When the monitoring voltage is between the upper limit voltage and the lower limit voltage, the relay will be disconnected, and the relays in other states will be closed.
 
H-4 is closed in the interval. When the monitoring voltage is between the upper limit voltage and the lower limit voltage, the relay is closed, and the relays in other states are disconnected.
 
H-5 Fixed-point monitoring When the monitoring voltage is higher than the lower limit voltage, the relay is closed, and when the voltage is lower than the lower limit, the relay is disconnected.
 
H-6 Fixed-point self-locking monitoring When the monitoring voltage is higher than the lower limit voltage, the relay is closed, and it will always be closed until manual intervention or power failure
 
H-7 Fixed-point pulse monitoring When monitoring each time, it is equal to the lower limit voltage (±0.1V), and the relay outputs a jog signal
 
F04 calibration mode long press SET button to enter in non-setting state, +- to select
The default is 0 error, if you need to set up on-demand adjustment,
For example, the actual input voltage is 12.5v, and the module displays 12.4V. At this time, you can modify the error here to 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 modify the error here and set the error to -0.1V, that is, 12.6-0.1=12.5
