Guide of air filter maintenance

02/01/2019

Compressed air system in factory plays an important role. In order to ensure the stable operation during the manufacturing process, the regulary maintenance is nescessary . However, there are many different problems in fact such as: Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduce using time of compressor accessories (air filter, oil filter, oil separator ...). On the other hand, the recommended maintenance in some factories is not seriously followed and there are deviations. To extend the life of the machine as well as compressor components and ensure operator safety Air compressors are very important to maintain regularly and technically correct.Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduced use time of compressor accessories (air filter, loc oil, oil separator ...).

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.
