[labnetwork] EV620 not initializing

[Hitesh Kamble]

Hello Chito,

What i understood from your description is optics initialise, cover down
but it doesn't reach to upper position? And gives initialisation error at
"UC04:*" ?

This is related to Way measurements system which is combination of Z-motor
control and hardware settings.

To identify issue>> access software in service mode: At login window, enter
id password and click 3 times on EVG logo. You'll bypass initialisation and
can access tool in High-level mode. There try to operate cover up/down. If
this function does not work then try below troubleshooting.


Checks1 : Open electronic box where you will see Z-motor controller. It
should not be "F" on 7-segment display. If yes battery could have drained
completely or firmware lost.
Solution: Replace battery and install firmware again.

Checks 2: There is a limiting screw in the Top side of the cover.It´s a M10
Nut screw near the center of the cover when you look onto the cover.

When this screw is loosen, the cover can´t reach it´s upper position for
initialization.





Thanks,
Hitesh Kamble,
