The self-protection function of the KOTECH air compressor

Time: 2022-05-05 14:35:52

KOTECH air compressor in the process of operation, there may be high temperature, low temperature, sensor failure, phase sequence error and other prompt alarm and shutdown, these are some of the protective design of the KOTECH air compressor protection,  screw KOTECH air compressor with its safe, reliable, stable characteristics to become the mainstream products of the KOTECH air compressor market, the configuration of the controller has a safety protection effect on the KOTECH air compressor, to ensure the good operation of the KOTECH air compressor,  when the failure problem occurs, you can automatically take protective measures to reduce the loss of the protection of KOTECH air compressor and economic losses. The specific protective effects are as follows:

1.Motor protection

The KOTECH air compressor controller has overload, phase loss, unbalance protection, high voltage, low voltage protection for the main motor, and overload protection for the fan.

2.Discharge over-temperature protection

When the discharge temperature is higher than the set temperature, the controller alarms the shutdown, and the on-site fault shows "high discharge temperature".

3.Air supply pressure overpressure protection

When the discharge pressure is higher than the set pressure high limit, the controller alarms the shutdown, and the on-site fault shows "high discharge pressure".

4.Low temperature protection

After the KOTECH air compressor is turned on, the system detects that the discharge temperature is lower than the low temperature protection value set in the manufacturer's parameters, the controller alarms the shutdown, and the on-site fault shows "discharge temperature sensor failure".

5. Anti-reverse protection

When the protection of KOTECH air compressor is stopped, when a phase sequence error is detected, the field fault shows "phase sequence error", and the protection of KOTECH air compressor is not allowed to start. At this time, you only need to arbitrarily swap the two-phase power cord and watch the motor turn.

6.Sensor failure protection

When the pressure sensor or temperature sensor is open, the controller alarms the shutdown. The field displays "Pressure Sensor Fault" or "Temperature Sensor Fault".
