Visually inspect to ensure that the DOK-LOK
barrier obstructs the R.I.G. of the trailer being
serviced before operating the dock leveler.
Restraint Locking, LOCK Button Pressed
Trailer has backed into loading dock and is parked
firmly against dock bumpers. Barrier extends out of the
pit from stored position and moves up to obstruct R.I.G.
Inside light is steady red alerting the operator that an
unsafe condition exists and barrier is in transit. Outside
light is flashing red alerting truck driver not to move.
If horn sounds, go to FAULT state, otherwise go to
Restraint LOCKED.
If trailer can not be restrainted due to a lift gate
or other obstruction that could become
damaged, go to OVERRIDE state.
