Compression bolt torque of compressor suction vent is 11
±1 N.M.
|
| Installation angle |
Compressor body not to be tilted (the angle between the main axis of the compressor and the horizon should not be
greater than 5 °)
|
| Others |
Electric compressors should be avoided from being installed at the outlet of the condenser to ensure adequate cooling of the controller
|
|
Compressor needs refrigerant cooling motor and controller,
suction pipe should be added insulation pipe
|
Suggest the compressor start 6 seconds before opening the condenser fan, after the compressor stops, the condenser Others fan shuts off for 30 seconds
|
To prevent the system entering too much moisture and
causing insulation to drop off, the compressor suction outlet
should be installed in a closed system immediately after
opening (within 5 minutes)
|
Compressor should be installed with damping pad to achieve the purpose of vibration reduction and noise reduction

4.1 Connector
4.1.1 Control signal definition
The controller is equipped with a pre-charge circuit, the main body is pre-installed with the whole car power
supply, control signal docking connector, the port of the connector is defined as follows:
1
、
Main power
Main power supply (A red positive/B black negative): SC10-8 (wire harness length 55cm)
2
、
Signal Input Port
P1/P2
Control start-stop line (yellow/green): DJ7022-2-11 ---The highest output of the yellow line is 5VDC,
<1A, and the yellow-green line is closed at full speed.(Wire harness length 45 cm)
P3/P4
Fault Output Signal Line (Purple/Black): SM2.5-2P(Wire Harness Length 45cm) ---Connectible LED
Lamp
Note: Please make sure that the plug-in corresponds to the positive and negative poles of the connector
before power-on, which will cause irreparable damage in an instant.
4.1.2 Fault Signal LED Lamp Description:
1. Flash once, pause once-normal standby state.
2. Flash twice and stop once -overload protection or short circuit of motor phase line.
3. Flash 4 times, pause 1 time -under-voltage protection.
4. Flash 5 times, pause 1 time -over-voltage protection.
5. Flash 10 times, pause 1 time -external temperature protection.
4.2 Electrical connection
5. Compressor operation control strategy
5.1 Compressor operation
This type of compressor can be controlled by start-stop (or 0-5VDC speed regulation).
5.2 Protection
◆
Over-voltageprotection: after over-voltage, stop immediately, voltage recovery, delay 30s restarting
◆
Under-voltage protection: after under-voltage, stop immediately, voltage recovery, delay 15 S restarting.
The over-voltage and under-voltage values are 15VDCand 11VDCrespectively. The recovery voltage is
over-voltage protection 13.5VDC recovery, under-voltage protection 12.5VDC recovery.
◆
Overload protection: when the running current reaches the protection, the protection time is 1second.
After the overload protection stops, 30s restarts.
◆
Overheating protection: the controller has its own temperature protection, when the circuit board
temperature is higher than 65
℃
, immediately shut down, restore 55
℃
and rise again.
Drive compressor integrated design, through the cold end of the compressor surface cooling.
