This function description:
This product can accord the temperature in the cabinet to adjust the speed of the compressor, and has the error diagnosis function, use touch buttons to replace the traditional mechanical buttons, blue-ray digital pipe display, blue LED internal lighting.
Tolerance requirement:
The control board of contour structure size should comply with the corresponding design drawings requirements.
Each panel installation size should be consistent with the requirements of the relevant design drawings.
Parameters
1. Rated frequency: dc input
2. Rated voltage: DC12V
3. Standby power: < 500 m/W
4. Whole machine power: <100 W
5. Temperature control scope: 15-18 °C
Appearance and structure:
1. The control board printing "shall be complete, clear.
2. The plate on the show part of show for a Φ 3.0 red LED display compressor ERRO signal, a Φ 3.0 green/orange double color lamp instructions compressor open/stop state, a four 8 period of blue-ray digital pipe display the temperature in the cabinet and thermal resistor (NTC) physical state and other information.
Function is introduced:
A. master control board
1, digital pipe specifications: 30 * 14 mm, blue-ray digital tube.
2, 4 buttons: POWER, SET, UP and DOWN.
(1) POWER: as a "POWER" button, switch a machine's switch machine state.
ON state: POWER lights up, start refrigeration mode.
OFF state: no shows, POWER lamp, into standby mode.
LED instructions:
POWER indicator is double color LED lights. Orange/Green respectively.
After power on the refrigerator, keep off the state before, if power lost before to boot, the boot after power up,
Conversely, the corresponding for shutdown state, if shutdown state, the need to press POWER button, to boot, POWER emit light.
According to the temperature in the cabinet and controller will set temperature numerical, decided to start compressor and closed.
Note:
A, the start of the compressor and close control still depends on the open/off voltage, NTC open/short circuit fault, not depend on the "ERROR" signal, because the compressor control box will automatically processing.
B, compressor mistakes in the fault signal voltage of red LED instructions, once detected a voltage control box fault and control board detected owe pressure fault when, should change LED instructions to orange, and digital tube closed, if the fault disappear, the recovery digital pipe display.
Compressor closed, POWER orange light, compressor start, POWER green light.
ERROR will be Red lights.
Fault instructions:
The fault of instructions for 500 ms for a cycle, accounting for more than 50% of the empty for pulse signal for a fault signal
A, compressor fan over current protection, compressor control box every 4 S issued two fault signal.
B, compressor start mistake, compressor control box every 4 S issued three fault signal.
C, compressor minimum speed error, compressor control box every 4 S issued four fault signal.
D, compressor overheating protection, compressor control box every 4 S five a fault signal.
When controller detects is failure, put on your hazards light up in the same period, and record fault type.
Digital tube, LED to the height of the PCB for 13 mm.
An overview function:
Electricity, the press POWER button boot, if NTC and input voltage of normal, they showed a plate of digital pipe display refrigerator actual temperature, when did not arrive at set temperature, compressor, green LED lights up, when you get to the set temperature, to orange LED light, if NTC short circuit or open, they showed a E-r, at the same time, to orange LED light, show the actual temperature after recovery.
Note:
Normal work mode (except sensor fault, voltage shortages outside), every time must be closed compressor
Lasts for 5 minutes, reset temperature or temperature compensation value, once effective (LED flashes 2 times),
Switch of Compressor without delay.
When testing to battery voltage less than 10 V, open relay, external charger will charge the battery to:
When the battery voltage more than 14 V, close relays and charging.
When the refrigerator door open, internal fan stop running, the door closed, internal fans start running.
ABS voltage (battery voltage) test:
CPU detecting input voltage and judge turns on/off the phone voltage.
A. shutdown voltage confirmed: when boot, compressor operation, each 2 second with detection for whether for shutdown voltage. If it is shutdown voltage, the orange lamp with 4 seconds a cycle ablaze 250 ms.
B. boot voltage confirmed: when to boot voltage value, is not LED flashing, resume normal work.
