4 Service and Maintenance

4.1 General remarks
The ITC8xxx modules do not need any maintenance by the user.
In order to ensure best performance, accuracy and reliable operation, Thorlabs
recommends a recalibration cycle of 24 months.

4.2 Troubleshooting

In case that your PRO8000 / PRO800 system shows malfunction please check the
following items:
Module does not work at all (no display on the mainframe):
Mainframe PRO8000 (-4) / PRO800 connected properly to the mains?
Connect the PRO8000 (-4) / PRO800 to the power line, take care of the
right voltage setting of your mainframe.
Mainframe PRO8000 (-4) / PRO800 turned on?
Turn on your PRO8000 (-4) / PRO800 with the key mains-switch.
Control the fuse at the rear panel of the PRO8000 (-4) / PRO800 mainframe.
If blown up, replace the fuse by the correct type
(refer to your PRO8000 (-4) / PRO800 mainframe operating manual to select
the appropriate fuse)
The PRO8000 (-4) / PRO800 display works, but not the module:
Is the module inserted correctly and are all mounting screws tightened?
Insert the module in the desired slot and tighten all mounting screws
properly.
You don't get the desired laser output power
Is the interlock closed?
Control the resistance between the interlock pins of the connector jack not
to be more than 430 Ω.
(refer to section 1.6.3, "Connecting interlock and status " on page 18)
