ULTRAHOOK UHR40 VEHICLE RESTRAINT
OPERATION AND PERFORMANCE CHECK
BEFORE DOING ANY INSTALLATION, MAINTENANCE, INSPECTION OR TROUBLE
SHOOTING, BARRICADE ALL AREAS FROM TRAFFIC AROUND THE WORK AREA
INSIDE (AND OUTSIDE IF APPLICABLE) FOR SAFETY AND POST APPROPRIATE
WARNING SIGNS.
FAILURE TO CONFIRM THE CORRECT OPERATION OF THE VEHICLE RESTRAINT IN
ACCORDANCE WITH THESE INSTRUCTIONS MAY RESULT IN PROPERTY DAMAGE,
BODILY INJURY OR DEATH.
THIS OPERATION AND PERFORMANCE CHECK MUST BE PERFORMED PRIOR TO THE INITIAL USE OF THE
RESTRAINT AND THEREAFTER ON A DAILY BASIS:
1. There are four proximity switches employed on the equipment - sensor#1 (hook extend), sensor#2 (rear impact
guard not engage), sensor#3 (hook retract) and sensor#4 (hook down). Confi rm proximity sensors are properly set
up (see ADJUSTMENTS AND TESTING on page 14).
2. With no vehicle docked, ensure the hook is in the stored position (fully back and tilted up) and the 3-position selector
switch is in the “DISENGAGE” position. The inside red light must be illuminated and the outside green light must be
illuminated. No other lights must be illuminated.
3. Turn the 3-position selector switch to the “ENGAGE” position. The hook must tilt down to the fully lowered position
then extend outward. When the hook begins to move, the outside red light must illuminate. Once the hook is fully
extended, the hook must fully tilt up, then retract towards the dock leveler, then stop approximately four inches (4”)
away from the dock face. The alarm must sound continuously and the inside red panel light must fl ash slowly. No
other lights must be illuminated.
4. To clear the missed rear impact guard error alarm, turn the selector switch to “DISENGAGE”. (Note: For any other
error, all functions cease until the “RESET” button has been pushed. See TROUBLE SHOOTING GUIDE on page
25). The restraint will return to the stored position by turning the 3-position selector switch to the “DISENGAGE”
position. The inside red light must be illuminated as soon as the switch is turned, however, the outside red light
must remain illuminated until the hook has fi nished moving to the stored position. Once the hook has fully returned
to the stored position and stopped moving, the outside green light must illuminate. No other lights must be
illuminated.
5. Turn the 3-position selector switch to the “OVERRIDE” position. (This will allow the dock leveler to operate
independently of the restraint.) The inside red light must turn off and the inside yellow light must illuminate. The
outside red light must remain illuminated. No other lights must be illuminated.
6. Turn the 3-position selector switch back to the “DISENGAGE” position.
7. Properly position a transport vehicle at the dock. The vehicle must be centered in front of the dock and backed
fi rmly against both dock bumpers. Turn the 3-position selector switch to the “ENGAGE” position. The hook must
fully tilt down, then extend outward. When the hook begins to move, the outside red light must illuminate. Once
the hook is fully extended, the hook must tilt up stopping once contact is made with the truck/trailer’s rear impact
guard and then retract towards the truck rear impact guard. When the hook has engaged and secured the truck rear
impact guard, the hook movement will stop and the inside green light must illuminate.
