Polar 92X Errors_Limit Switch Error Table B/F 2369

hoping anyone can help with my Polar 92x Errors.

All of a sudden upon startup it opens up to;
1. Scan Refernce Position
2. Auxilary Operation, No Pos.
When I carry out 1. The backgauge only moves backwards half way & stops with Error_No Reference Position Impulse 653, press continue & it moves all the way to the back and then it stops with ERROR_Limit Switch Error Table B/F 2369.
It does not move forward at all when inching forward.


When I go into 2. Auxillary Mode;
It only goes backwards when press back
When I press forward, ERROR_Backgauge End Position (77),
Can only inch forward.
It only moves backwards not forward.
I check/clean all the limit switches and adjusted and they are all ok.
Hope anyone can assist asap.

 

Hi sir the error 653,can be this cause:
This error message is displayed when:
- No electrical reference pulse is detected during the reference run
- No electrical reference pulse is detected in the switching phase of the
mechanical reference switch
- No electrical reference pulse is detected when moving over the reference
position stored.
- During the reference run, neither the mechanical nor the electrical reference
point is detected.
Check this:
- Make a reference run and move the backgauge along the entire width of the
table, if the position of the mechanical reference point switch has been modified
- Check functioning and position of sensor B 341
- Check cabling B 341
check S1 electrical interlocking of rear-table guard (neither cut nor
backgauge movements are possible)
- Check backgauge motor, electrical connections and it's cabling.
