Type: 12 V Automotive Electric DC Compressor. Compressor style: 12V Semi-closed Horizontal Scroll. Speed range: 1000 - 2100rpm. Refrigeration oil: POE oil RL68H/130ml. LED Blinking hint is special designs for the fault.
During the using, some irreguar operate lead to some wrong like, Excessive current, Undervoltage, Locked rotor, Standby mode, over heated, over preasure. This Air conditioner compressor will turn to protection mode and hint by LED blinking. Blinking 1 times, pause 1 second: Standby mode. LED off, compressor normal operation state. Fast blinking 2 times, pause 1 second: Excessive current, Over 50A.
For example, the system pressure is too high, or the compressor motor fails and the current is too high. (1) If the compressor stops for protection within 20 seconds after startup, please check whether the power cord is tight, whether the fuse screw is properly connected, and whether the battery terminal and battery connection are oxidized.
Please use sandpaper to clean them and then reconnect them. The 20-second protection is basically a power problem. Especially for the second-year machine, the battery connection is corroded for a long time and the end is oxidized.(2) If the protection stops for more than 2 to 3 minutes, it is basically caused by excessive system pressure 1 too much refrigerant, 2 system blockage, 3 dust accumulation in the refrigerant leads to poor heat dissipation, 4 the electronic fan does not work or the electronic fan carbon brush wears and the speed decreases. (3) You can turn on the power saving mode or energy saving mode for testing. These two modes have small currents and basically do not provide large current protection. These two modes do not provide protection. The basic judgment is that the controller and the internal panel electrical appliances are good, please check other reasons.
Fast blinking 3 times, pause 1 second: Locked rotor protection. Troubleshooting: It is basically caused by the mechanical failure of the compressor, and part of it is that the power supply is not connected properly, and the controller cannot get strong current.Fast blinking 4 times, pause 1 second: Undervoltage protection. Troubleshooting: 1 The battery is really undervoltage and needs to be charged.
2 Undervoltage is reported at the moment of startup. It is possible that the power supply is not connected properly and is virtual.3 The line is too long and the panel undervoltage value needs to be adjusted (the controller undervoltage value is 10V). Fast blinking 5 times, pause 1 second: controller failure. Fast blinking 6 times, pause 1 second: Electric fan fault. Troubleshooting: In the startup state, the controller signal line is powered, and the compressor is running normally at this time. Please check whether the electronic fan is working, or whether the electronic fan line is detached or short-circuited.
Please judge whether the electronic fan is good or bad. Fast blinking 7 times, pause 1 second: Motor lack of phase. Troubleshooting: Please check whether the compressor motor is connected properly or whether the motor is burned. Fast blinking 8 times, pause 1 second: Compressor over heated protection. Troubleshooting: Check whether the compressor is overheated or whether the temperature line is connected properly. You can short-circuit the temperature line for testing. Fast blinking 9 times, pause 1 second: Pressure switch protection. Troubleshooting: Please check whether the system pressure is too high, or directly short-circuit the pressure line for testing. The operating voltage of the controller is: 10V 16.5V. The undervoltage value is 10V, the control overcurrent is 65A, the working environment temperature is below 60C, and the electrical level is P68.
