ERROR DETECTED BY OGP BOARD
Aperture Error: 2
Code: 20-1020-02
Name: Aperture Reset Error.
Class: Error
Description: OGP could not detect Aperture reset position.
Potential Cause / FRU:
1. Aperture Assy
2. Aperture Motor Driver
3. Cabling between OGP and Aperture Photo Sensor or between OGP and Motor Driver
Most probably when you remove the bowtie filter for calibrations you touch the home position optical sensor (located on left side on interior of collimator) or mechanics of this one, I mean the sensor flag, or one of the collimator cables. This cables have small (brown most probably) connectors if this are little out, you can face this kind of problems.
Because the system was running before, once again check the sensor and collimator cables there are only the parts that are possible to be affected during tube replacement.
Yes, the opto has a small red LED , that light if not blocked.
To see it, you need unmount the collimator cover, fixed with 8 mm nuts at the squares front face of collimator ( not the aluminum part)

Hello,
Most probably when you remove the bowtie filter for calibrations you touch the home position optical sensor (located on left side on interior of collimator) or mechanics of this one, I mean the sensor flag, or one of the collimator cables. This cables have small (brown most probably) connectors if this are little out, you can face this kind of problems.
Good luck

restart the unit.
APERTURE Assy is easy to be defective for some reasons.
It is cheaper

Check blades movement when you push OGP reset button. Probably step motor, or controller bad.

Check if opto for 1 mm is active, then try to do service scan with 1 mm slice; if works, you have problem with step motor, or pcb driver
