Hi sir:

I will try to help you.

1) The locking valve (use the schematic diagrams) Y315 is switched Off, +42 Vdc is missing.

2) see the plug connector CU 6.8 +CU 6.9

3) a) Check supply Voltage for +42Vdc-50Vdc in the Unit CU, test the fuse F4 b) measure the resistance for locking valve Y315 if is o.k c) check connection connector CU 6:8+9, for dirty, loose wires, or broken wires, or bad contacts, clean very well.

 

Great thanks to you. The problem is solved.

 

Great job Sir!
