BASIC TROUBLESHOOTING GUIDE
PROBLEM 6: SOLDERING IRON TEMPERATURE DISPLAY PANEL
SHOWS “PLUG” CHARACTERS
Case 1:
The system shows “PLUG” from the soldering iron temperature
display panel .
SOLUTION 1:
Check if the soldering iron connection assembly is properly
connected and secured to the receptacle on the control panel.
SOLUTION 2:
Make sure the soldering iron tip is properly inserted and
secured inside the handle. Loose contacts between the tip and handle can also
cause this error message.
PROBLEM 7: AIR PRESSURE LEVEL IS SIGNIFICANTLY LOW NO
MATTER HOW HIGH THE AIRFLOW LEVEL IS CALIBRATED
Case 1:
Check the mains voltage (AC power source). If the voltage level falls
significantly low, about 15-20% lower than the standard, there will also be a
noticeable drop in the air pressure level.
SOLUTION:
Please refer to your local power service provider.
Case 2:
The microcontroller might have detected the operating frequency
incorrectly. The user will notice that airflow level is weaker with reference to the
airflow gauge compared with the displayed value.
SOLUTION:
Turn off the unit and on again to let the device re-detect the proper operating
frequency
