6 Fault Diagnosis
Some simple tests are described in the following for you to carry out yourself
in the case of malfunction. In the case of more difficult problems with the indi-
vidual functions, please contact our service personnel. The tests described
here are not meant to lead you to carry out maintenance work yourself but to
provide our service personnel with information which is as accurate as pos-
sible.
Testing the PDV is limited to such tests in which the housing does not have to
be opened. Opening the housing can cause a malfunction and will invalidate
the warranty.
If required, please contact our service department. Based on your fault
description, further procedure will be determined.
If the PDV has to be sent back for repair, always use the original packaging
and enclose an exact description of the fault.
6.1 No Laser Beam
If no laser beam is emitted, check the following:
1. Is the beam shutter opened ?
2. Is the PDV connected to the mains supply as described in
SECTION
3.4.2 ?
3. Does the display on top of the PDV light up or does it show a menu ?
If the display is not lit up, or is not showing anything, it can be assumed
that there is a fault with the mains supply.
4. Does the housing feel warm to the touch as normal after about 15 minutes
in operation indicating that the laser is active ?
5. Does the display show the following warning?
The laser has been switched off because the temperature limit inside
the PDV has been exceeded. Switch off the instrument and let it cool
down.
WARNING
