Error Diagnosis and Troubleshooting
6.1
General Errors
If the soldering station does not operate as expected, check the following items:
If the soldering tip does not become hot after the above items have been checked, you
can use an ohmmeter to check the heat resistance and the temperature sensor for con-
duction (Figure 18).

Fig. 16 shows what the display looks like when there is no
tool connected to the soldering station
Insufficient temperature
The temperature measured by the temperature sensor is
about cold junction temperature (approx. room tempera-
ture). The character string is displayed (Fig. 17) until the
temperature of the sensor has risen sufficiently above cold
junction temperature.
•
Is main voltage present? (Correctly connect the mains lead to the
device and socket.)
•
Is the fuse defective? 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 iron correctly connected to the supply unit?
Continuity check for TECH TOOL, POWER TOOL und
X-TOOL heating element
The continuity resistance between measuring points 1 and
6 should be between less than 6 Ohm (at cool soldering
iron). In the event of interruption, the heating element is
to be replaced (see left).
