Error diagnosis and remedy
7.1
General errors
If the soldering station does not operate as expected, check the following items:
• Is the mains voltage present? Correctly connect the mains lead to the device and
socket.
• Is the fuse defect? The fuse can be found at the rear side of the device in the mains
connecting socket.
•
Note that a defective fuse may also indicate a deeper cause of error. Simply
changing the fuse therefore generally does not suffice.
• Is the soldering tool correctly connected to the supply unit?
7.2
Other faults
•
This station permanently shows a too high actual temperature. This fault can occur
when operating a CHIP TOOL. In this case switch off the station and replace the sol
-
dering tool with a flawless one.
•
Should the soldering station be overloaded, it will automatically shut down and the
display will be empty. Once the soldering station has cooled down to a sufficient
level (approx. 30 minutes) work can be continued.
7.3
Continuity test for i‑TOOL
If the soldering tip is not heated up correctly after the previously mentioned points have been
checked, you can check the heating element resistor and the temperature sensor with an ohmmeter
for conductance.
ATTENTION! Risk of burning!
Only perform the following remedial action after the soldering tool has cooled down.
7.3.1
i‑TOOL heating element
Between measuring points
①
and
②
you should be able to measure a volume resistance of
approx. 3.5 ‑ 4.5 Ohm (with cold soldering iron). In case of interruption the heating element must be
replaced. (
