Home Forums General Discussion Technical Questions Schindler 9300 b r0 fault

Anyone has encountered this fault?
Maintenace plug bridges on top ok.
With top control panel laid down escalator runs perfect.
With control box on top upright, 8f escalator is running and any safety circuit is triggered PEM board shows b r0 and won't reset.

Then if control panel 8s laid down again PEM can reset..

Maybe someone knows whic wires/connectors/safeties trigger this state?

r.0 is inspection operation

try to :
when r.0 is show up just push the emergency stop switch (stop sw. on side of the handrail ) keep pressuring and with the main key to start the escalator
just switch up and down 3 or 4 times , status should return to d.o

I understand but my question is why is it doing this fault when putting top control box in pit or pressing stop near handrail. Normally it would revert to b d0 automatically.
