2. Element outlet Over-Temperature Protection
When the element outlet temperature is higher than the upper limit of set temperature,
the controller will stop the machine,The display will show “ HIGHT T ”.
3. Non-reversing Protection of Air Compressor
When three-phase supply phase sequence connected to the air compressor is not the same with that
set for the controller, the failure is displayed as “ PHASE REVERSAL ”, as a result, the controller cannot
start up the motor. Then just change any arbitrary two-phase power lines leading to check the rotation
of motor.
4. Overpressure Protection of Pressure Supply
When the air discharge pressure is higher than the upper limit of set pressure, the controller will stop
the machine, the failure is displayed as “
HIGH P
”.
5. Malfunction of protection sensor
When pressure sensor or temperature sensor is disfunctional, the controller will stop the machine. the
failure is displayed as “ **SENSOR FAULT ”.
14.2.4 Removal of Common Failures
1. Failures
Review
When a fault occurs, the controller in the main interface displays the current fault content.
For example, when the pressure sensor failure, it displays the following interface:
2. Common Failures and Causes
Failure Reason Disposal method
Air Exhaust
Temperature too
high
Bad vent condition, Oil lacking etc. Check the vent condition and lubricant
amount etc.
Temperature
Sensor Failure
Cable off or PT1OO damaged Checking the wiring and PT100
Over Pressure
The pressure too high or the
pressure sensor failure
Check the pressure and the pressure
sensor
Pressure Sensor
Failure
Cable or Sensor damaged or
incorrect cable connection.
Check the wiring and sensor
Lack Phase
Power phase lacking or the
Contactor terminal damaged
Check the power and contactors
Overloaded
Voltage too low, cooler blocked,
Bearing Wear off or other
mechanical failure or wrong set data
etc.
Check the set data, Voltage, motor
bearings, cooler and other mechanical
system.
Unbalance
Power unbalance, Contactor
damaged or the internal short-circuit
of the motor
Check the power, contactors and the
motor
Rotor Lock
Voltage too low, pipes blocked,
Bearing Wear off or other
Check the set data, Voltage, bearings,
pipes and other mechanical system.
