Fold the safety rails and the bridge plate back on the platform surface. Switch Sw0 must be activated to slide-in.
Use the EMR function to determine if the platform doesn't slide out because of mechanical reasons (wear or damage
on gear wheel, tooth rack, guide rollers,...) or because of electrical reasons. If mechanical, remover the top cover of the
cassette, disassemble and service / repair / replace the failing parts.
If electrical, start with following the procedures under §5.2. Determine if there is 24V coming from the vehicle batteries,
dashboard switch, and if the power relay Rbat is working OK.
Push "LOWER / SLIDE IN" button and measure if the control unit and its wiring are functional.
Measure ingoing & outgoing voltage on the mini-relays R0 - R2, and replace if required. Measure ingoing & outgoing
voltage on electric motor Me, and replace if required.
