The type of RBI depends on the age and model of the lift, there are 2 versions out there. One Blue (old version) and a black (new version).

Normaly these boxes only get a power supply (30vdc from the RSL link) and then there is a relay inside where the signal to the controller is connected.
If you bridge the 2 wires from the relay, your 2SE fault should be off.

BUT ONLY FOR TESTING!
