45°C. If it exceeds 45°C, excessively high air discharge temperature will be caused in
the compressor.
1.4 Control Protection System
For intelligent automatic control, the compressor has a micro-computer controller which
can adjust the operating state of the compressor according to the actual air consumption
conditions of the user’s application.
If the air consumption of the user is low or the air application is paused, the main inlet
valve will be shut off to allow the compressor to operate at light load and turn into the
unloading state, consequently realizing the energy-saving target. After the air
consumption is recommenced, the micro-computer controller will open the main inlet
valve again to enable the compressor to operate at the full load and recover the loading
operation state. At the same time, the micro-computer controller will monitor the unit.
If any abnormal condition - such as motor overload, air discharge over-temperature, etc.
- occurs to the unit, it will automatically shut down the compressor to protect it against
damage.
A safety valve is installed in the oil-air tank. If the pressure inside the oil-air tank
exceeds the setting, the safety valve will automatically open to quickly discharge the air
and release the pressure, ensuring the safety of the unit. The unit has the ideal pressure
relief function. Therefore, the safety valve will not open in normal operation.
1.5 Electrical System
The electrical system consists of the main motor, electrical control cabinet assembly,
solenoid valve, temperature sensor, pressure sensor, and operation panel.
To further protect the main motor against overheating damage due to abnormal
conditions, the operating current of main motor will be monitored by the controller. If
the motor current exceeds the allowable current, the compressor controller will perform
immediate shutdown protection, and the motor overload will be shown on the operation
panel at the same time.
The electrical schematic diagrams are shown in Fig’s 1-5 and 1-6.
Caution: The user should provide the necessary short circuit protection and
other safety devices ahead of the lead-in power supply cable of the compressor, and
the secure grounding wire should be present.
Warning: It is prohibited to remove and install the connecting lines inside the
electrical control cabinet and from it to individual motors without permission!
