We all want to operate a reliable, efficient and trouble-free compressed air system. Following the equipment manufacturer's daily and weekly maintenance checks can help you to deal with this problem. After all, prevention is better than cure! For many companies, compressed air is considered to be very important for plant operations. Air compressors are high-value machines if it is not well maintained, resulting in high energy costs, the machine can get unexpected incidents affecting the production schedule and even damage the product.

The air reclever tank is an important device in the compressed air system with these following function of: Accumulating gas, stabilizing pressure, Increase idling time, condensating water in the output etc..

Air dryers repairs

Atmospheric air always contains moisture: the higher temperature, the higher humidity is typical for the air. However, when compressed air is accumulated moisture, the water is condensing on the internal parts of the equipment and pneumatic systems. It is the case of corrosion and reduce the equipment lifetime. Therefore usually the additional air treatment equipment, like air dryer are used to avoid the accumulation of moisture in the pneumatic system.

Troubleshooting of Handsome II

Step 1: Check the condition of the LED lamps and find out the cause of emergency shutdown by refering to the table below:

RUNNING lamp	FAULT lamp	Fault detected	Operation of air compressor
OFF	ON	Compressor motor overcurrent or motor coil high temperature.	Emergency shutdown.
OFF	Blinking (1.2 sec./cycle)	Discharge temperature higher than 110ºC(230ºF) or sensor short circuit.
OFF	High pitched blinking. (0,4 sec./cycle)	Sensor failure or poor connector contact.
BLINKING	ON	Dryer failure.	Emergency shutdown unless the conditiuous operation is selected.

Step 2: Eliminate the cause of the fault.
Step 3: Press the START button (green) to restart and the FAULT lamp will go out.
Caution:

The dryer safety machanism is activated when the START and STOP buttons are pressed frequently.
Keep 3 minute interval between stop and restart.
Countermeasure for motor overcurrent/ motor coil high temperature.

Meter panel:

LED lamps on the meter panel	Reset
Power Running Fault	Reset thermal relay

When excessive curent passed in the motor, the thermal switch trips and the compressor shuts down. Remove the cause of overcurrent and press the thermal relay reset (blue) button. The lamp will go out when the START button (green) is pressed to restart.

Reduced cooling air volume for the motor may increase motor temperature, activating the motor protector and stopping the compressor. Eliminate the cause, i.e clogged dust filter or the like. Press the START button ( green) to restart, and the FAULT lamp will go out.

When the motor of Handsome II does not starts.

Step 1: Turn off the earth leakage breaker.
Step 2: Interchange two of the three phases in the power unit and connect again.
Step 3: Return the breaker on and see if the motor starts.
