2.
Solder.
Heat the component and the conductor connections.
3.
Clean the circuit board.
Once you have completed the soldering process, the board should
be cleaned and the flux removed.
Troubleshooting
1
st
problem:
The station has no electricity.
Solutions:
a) Check to see if the station is turned on.
b) Check the fuse. If it is burned out, it must be replaced.
c) Check the cable. Make sure that it is properly connected.
2
nd
problem:
The hot air temperature display always shows a temperature above 500
; after a short
℃
time it shows “Err 1.”
Solution: The temperature sensor is defective and must be replaced.
3
rd
problem:
The actual air temperature of the hot air iron does not decrease or increase based on the
desired target temperature.
Solution: The heating element is defective or worn and needs to be replaced.
4
th
problem:
The station vibrates too much.
Solution: Check that the four screws that hold the pump in place are properly and securely in place.
Unplug the station from the mains before opening the station to look inside.
5
th
problem:
The station is very loud.
Solution: Make sure that the security screw located in the center of the station bottom has been re-
moved. This screw secures the pump during transport and must be removed before using the station.
6
th
problem:
The soldering iron temperature display shows “PLUG”.
Solutions:
a) Check that the soldering iron has been inserted correctly.
b) Make sure that the soldering tip is properly inserted and properly secured inside the handle.
Loose contacts can also be a reason for an error message.
7
th
problem:
The air pressure is clearly too low, no matter how high it has been set.
Solutions:
a) Case 1: Check the mains voltage. If the voltage is 15–20 % lower than the standard, the air
pressure will also drop. Contact your electricity provider.
b) Case 2: The microcontroller could have incorrectly recognized the operating frequency. The
user might notice that the air pressure is weaker than the measured value. Switch the station
off and on again so that the value can be read out again.
8
th
problem:
The station behaves unusually; it works irregularly.
Solutions:
a) Switch the station off and on again. Also disconnect the station from the mains once and then
plug the cable back in.
b) Restore the factory settings of the station. Switch the device on and off while holding down the
“reduce hot air temperature” button. Wait until the display has finished tickering so that the
device is reset to the factory settings.
