6. Disassemble the collimator from the sensor head. Check each channel
inside the collimator for possible obstruction. If necessary, clean it with dry
air or very carefully with a bottlebrush. It should be perfectly clean.
7. Check the four-quadrant sensor. If dirty clean it with a cotton swab.
Warning: Never clean the 2 main lenses on the front plate, except after a dust
event when they can be cleaned with dry air.
The effect of the increasing dirt on the lenses due to time deposition can be
corrected at the data processing stage. Cleaning them will distort the
calculations.
8. Checking if the GOSUN and the TRACK are correct.
→
Launch a GOSUN scenario and look at the position of the sun spot compared
to the target on the collimator base.
If a large shift is visible on the azimuthal axis, please watch step 14 in the
installation part.
→
Launch a TRACK scenario and look if the sun spot is perfectly centered on
the target on the collimator.
If a problem is encountered, please refer to the troubleshooting part.
5.2. Corrective maintenance
Solar panel and wet sensor replacement
The wet sensor and the solar panel on the case are already mounted. They might be
replaced in case of breakdown.
1. Loosen the 4 nuts.
2. Withdraw the solar panel with its wire cautiously from the protection case.
3. Get back the 4 screw which are inserted in the solar panel slides and
replace the solar panel.
Note: To replace the wet sensor, the solar panel needs to be uninstalled.
