Module Highlights:
Operating mode:
Voltage upper limit: UL1, voltage lower limit nL1, the voltage upper limit is greater than the voltage lower limit (UL1> nL1)
U-1: Charging measurement: When the measured voltage is lower than the lower limit voltage, the relay pulls above; the upper limit voltage, the relay is disconnected.
U-2: charge measurement time control: set the charging time (OP); when the measured voltage is lower than the lower limit voltage, the relay pull, and then start the countdown OP time, the end of the timer, the relay off; when the measured voltage is higher than the upper limit voltage , The relay is disconnected.
U-3: Discharge detection: When the measured voltage is lower than the lower limit voltage, the relay is off, above the upper limit voltage, the relay pulls;
U-4: discharge detection time control: set the discharge time (OP); when the measured voltage is higher than the upper limit voltage, the relay pull, and then start the countdown OP time, the end of the timer, the relay off; when the measured voltage below the lower limit voltage , The relay is disconnected;
U-5: voltage in the range, the relay pull: when the measured voltage between the upper and lower limits, the relay pull, the other circumstances open;
U-6: voltage outside the interval, the relay pull: the measured voltage below the lower limit voltage or higher than the upper limit voltage, the relay pull, the other case the relay is off.
Product parameters:
1: Power supply voltage: DC6--40V(Working Power), voltage detection range DC 0--60V, suitable for less than 60V of the various batteries, voltage measurement error ± 0.1V.
2: charge and discharge time (OP) range: 0 - 999 minutes.
3:The digital tube shows the voltage of the battery.
How do I set parameters?
Mode selection interface: press the SET button for a long time to enter the mode selection interface, set the finished, a long time press the SET button and then release the exit mode selection interface, back to the main interface.
Additional features:
Serial port control (TTL level communication)
Communication standard:
The baud rate is 115200 bps
Data bits: 8
Stop bit: 1
Check digit: none
Flow control: none
Serial command:
"U-1": Operating mode (range U-1 to U-6)
"000": 0 - does not enable timing function, non-0 - enable timing function (range 001 to 999)
"Dw02.9": Set the lower limit voltage
"Up10.1": set the upper limit voltage (range 00.0V ~ 99.9V)
"Get": Get the current settings
"On": Allows the relay to turn on
"Off": Always turn off the relay
"Start": start uploading data
"Stop": stop uploading data
The above command can be any combination of two, need to be separated by commas
Such as: "dw02.9, up10.1" set the lower limit voltage 02.9V upper limit voltage 10.1V
Upload Status: Test Voltage + On Time + Status
"00.0V, 00: 00: 00, OP \ r \ n"
00.0V: Measured voltage
00:00:00: Relay on time
Status: OP relay on, CL relay off
STOP key function expansion:
Relay enable mode:
Press the STOP button on the main interface to switch between ON and OFF, the current status will flash, and then return to the main interface. (This function is an emergency stop function, a key to disconnect the relay)
Sleep mode:
Press and hold the STOP button for 2 seconds to release, to achieve C-P and O-d state of the switch, the current state will flash, and then return to the main interface.
