SL-300 (1998) Alarm EX2058 safety circuit

[ulfnilsen]

Hello
Have done a lot of search/trace . but the last relay of the saf module will not com .
Have changed All relays in safety module . saf module have 6 led's .But cannot figure out why the last relay (Y8.0) is not coming . It seems to be a loop that the setting is actually dependent of that the relay itself operates...

if anyone wants to help , I have doc on ladder/PMC prog (ladder) / el diagrams ..
best regards
Ulf
