VARIO 2
Error diagnosis and remedy
The volume resistance between the measuring points
①
and
②
should be 2.3 Ω ± 10%. If this is not
true, you must replace the heating element.
If you do not reach the specified values during the previously described test you should
return the tool to the Ersa Service for heating element replacement.
7.6
Continuity check for X‑TOOL VARIO
If the desoldering tip does not heat up correctly after the general errors and the other faults have
been checked, you can check the heating element resistor and the thermocouple for conductance us
-
ing an ohmmeter.
ATTENTION! Risk of burning!
Only perform the following remedial action after the soldering tool has cooled down.
7.6.1
X‑TOOL VARIO heating element
To do a continuity check of the heating element, first dismount the heating head like described in
chapter 6.2.6.4 [Maintenance and servicing X‑TOOL VARIO]. Refer to the following picture to check the
heating element of the demounted heating head for conductance using an ohmmeter:
Plug of X‑TOOL VARIO
• Measure volume resistance between the measuring points
①
and
②
.
•
The heating elements are okay if the resistance is in the range of 3.5 Ω (± 10 %).
If you do not reach the specified values during the previously described test, please
return the tool to the Ersa Service for heating element replacement.
7.7
Continuity test for i‑TOOL HP
If after checking the above‑mentioned points, the tip is heated incorrect, you can check the heating
element resistance and the temperature sensor with a resistance meter for continuity.
ATTENTION! Risk of burning!
Only perform the following remedial action after the soldering tool has cooled down.
