8.1 Troubleshooting
In the case that your ITC8000 shows malfunction please check the following topics:
u The module does not work at all (no display on the mainframe):
Ø Is the mainframe connected properly to the mains power supply?
· Connect the mainframe to the power line, take care of the correct voltage setting and
grounding of the mainframe.
Ø Is the mainframe turned on?
· Turn on the power key switch.
Ø Check the fuse at the rear panel of the mainframe.
· If blown, replace the fuse with the correct type (one spare fuse is inserted in the fuse
holder). Please refer to section Exchanging the Mains Fuse in the PRO8000 Series
Manual.
u The display works, but not the module:
Ø Is the module inserted correctly and are all mounting screws tightened?
· Insert the module in the desired slot and tighten all mounting screws properly.
Ø Is the desired module selected?
· Select the desired module on the display by means of the up- and down arrow keys.
(LED “SEL” on the front panel lights up).
Ø Is the LD/TEC output turned ON in the main menu or one of the sub menus?
§ Change the status setting from “off” to “on”. The LED “LD ON” / "TEC ON" on the front
panel of the module must light up.
Ø Is the hardware limit ILIM and / or the software limit IMAX set to 0?
§ Adjust the hardware limit ILIM by means of the potentiometer on the ITC8000 front panel
and the software limit ILIM in the channel menu to appropriate values.
