The BPM-12 electric paralysis protector is an intelligent electronic device installed on the battery. Monitor the electric quantity and charge and discharge state in real time while working. When the battery is about to run out of electricity, the battery will be disconnected in time in order to retain the minimum electricity needed for the next start-up, and to protect the battery from excessive discharge.

The equipment is connected between the electric bottom and the negative number of equipment by this method. It is often used for battery protection, RV double battery isolation protection, motorcycle electric protection, computer room spare battery protection and so on.

11.Military grade devices, built-in hardware watchdog, to ensure stable operation.

12. Disaster safety design, even in the case of the maximum failure of the chip and its surrounding circuits, the self-locking characteristics of the on-off controller can still maintain its normal turn-on and ensure the safety of driving.

Method of use

1. The equipment boot display screen is turned on, showing the product model and version, and entering the main interface after 2 seconds;

2. The main interface has four thin display content

84%: remaining battery capacity

12.63v: real-time bottom voltage

50%: disconnect power settings

When the real-time power is lower than the disconnected power and the well lasts longer than the set disconnect time, the equipment will cut off the power supply

Sm: devices work in enhanced security mode (no display indicates regular protection mode)

On：on and off status of devices

On- connected. 0ff- Disconnect,  Time to zero and disconnect immediately.

3. Key OFF/-:

When the screen goes out in standby state, click wake up screen display

In the bright screen state, click will perform the shutdown action, disconnect the battery from the electrical equipment: in setting mode, click to perform digital subtraction operation, see the setup wizard for details.

4. Key ON/+:

When the screen goes out in standby state, click on the wake-up screen to display

When the screen state, click will perform the opening action, connect the battery to power the device; in setting mode, click to perform digital plus operation, see the setup wizard.

5. Remote Controller:

OFF- disconnects battery from electrical equipment

ON- turns on battery to power equipment

6. LED: red light flashes to disconnect and green light flashes to turn on.

The red light flashes once in 1 second, indicating manual or remote disconnection.

The red light flashes once in 2 seconds, indicating that the equipment is automatically disconnected and that the remaining battery power is sufficient. The red light flashes once in 5 seconds, indicating that the power has been exhausted and must be charged immediately.

The green light flashes once a second, indicating that the bottom capacity is sufficient.

green light flash quickly, indicating that the remaining power is below the set value, disconnect countdown,

Special reminder:

A: When OFF is set up in safe running mode, there is no limit to the new opening, and disconnection is performed unconditionally whenever an instruction is received.

B. The safe operation mode is set to ON, at a real-time voltage Above 13.2v(The system thinks that the engine is running and the generator is generating normally). The equipment will not accurately respond to any disconnect instructions to ensure driving safety with maximum procedures (see the section on setting up wizard safety town switches for details).

Setup wizard :

1. Touch and hold down the ON/+ key for more than 2 seconds, click OFF at this time , screen shows that the SET MODE, is immediately loose

Turn on the button and the device enters setup mode.

2. Protection voltage: sets the disconnect voltage

Default 12.2v. The estimated residual capacity was 53%.

Press +/- to add or subtract settings.

Press the ON/+ key long after completion to enter the next setting.

3. Disconnect delay: sets the break delay

Default 300 seconds, when the battery voltage continues to fall below the set value

After 300 seconds, the equipment automatically disconnects the whole car.

In order to prevent frequent on-off, when the voltage is higher than 13.2v in the delay process, the delay will stop and return to the normal monitoring state.

Press +/- to add or subtract settings

Press the ON/+ key long after completion to enter the next setting.

4.Safe mode setting: safe mode switch

Turn on ON, by default for higher security.

When set to ON:

①. When the battery voltage is higher than 13.2V, the device is absolutely not allowed to disconnect, whether it is keystroke or remote control, as well as automatic, do not allow disconnection:

②. No matter how (automatic, keystroke or remote control) is disconnected, when the voltage returns to more than 13.2v, the equipment will be automatically turned on to ensure that the battery will be replenished in time.)

Press + /- add or subtract settings.

Press the ON/+ key long after completion to enter the next setting.

5. Save settings

Press + /- to select yes/no, to determine whether the device is saved

Parameter, and then restart into working mode

Note: at any time in the 3.4.5 steps above, you can long press OFF to cancel the setting, and the device abandons the set parameters and exits the setting mode.

Wiring instructions

Fix one end of the adapter to the positive or negative pole head of the battery, the positive or negative power line of the original vehicle to the other end of the adapter, fix the two wires of the host to both ends of the adapter, and connect the yellow wire of the host to the other electrode of the battery
