ULTRAHOOK UHR40 VEHICLE RESTRAINT
ADJUSTMENTS AND TESTING
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.
ONLY TRAINED AND QUALIFIED PERSONNEL SHALL PERFORM INSPECTION OR
MAINTENANCE AND SERVICE PROCEDURES.
NOTE:
This equipment has been fully tested, adjusted and confi rmed to be operational at the factory. If, however, some
proximity sensors have come out of adjustment during transportation and installation, the following adjustments may be
performed by a qualifi ed technician.
PROXIMITY SENSOR ADJUSTMENTS:
Check and/or adjust proximity sensors #1, #2 and #3 before checking and/or adjusting proximity sensor #4.
If the indicator lights located on the front face of the PLC do not illuminate as indicated in step 6 on page 12, visually
inspect for the LED light on the side of the proximity sensor. When the unit is in the “parked” position, proximity sensors
#1, #2 and #3 should be lit. If one or more is not lit, complete these steps for each one that is not:
a) The weather seal may be removed to get a clearer unobstructed view of the hook.
b) Loosen the jam nut positioning the proximity sensor.
c) Turn the body of the proximity sensor clockwise to advance it toward the bar until the LED light on the side
of the sensor comes on.
d) Tighten the jam nut positioning the proximity sensor.
e) Check to ensure the indicator light on the front face of the PLC is also illuminated.
If the sensor body advances until it touches the bar and still the light does not come on, back the sensor body off and
recheck all wiring. If you are still unable to adjust the proximity sensor, contact your authorized Pentalift representative.
When proximity sensors #1, #2 and #3 have been confi rmed operational, check and adjust proximity sensor #4.
STAY CLEAR OF THE EQUIPMENT’S OPERATING PATH AT ALL TIMES.
a) Put the controls into Maintenance Mode. See MAINTENANCE MODE on page 26.
b) Manually step the hook forward (“OVERRIDE”) and down (“RESET”) until you have reached the target position;
the recommendation is to have 1/2” of clearance from underside of the hook to the front frame plate or
driveway.
When in maintenance mode, it is possible to extend the hook without tilting down and this
could cause the hook to crash into the frame of the dock leveler. Make these steps slowly
and carefully to avoid any possible impacts and damage.
c) If the hard stop prevents the hook from reaching close to the frame, lossen the tilt proximity sensor #4 jam nut and
back the proximity sensor out, this MUST be done to prevent damage to the proximity sensor. Back off the
adjustment bolt to achive the desired tilt position, then tighten the adjustment bolt jam nut.
d) If the hard stop does not contact before the hook touches the frame, advance the bolt toward the hook assembly to
achive the desired tilt position.
e) The proximity sensor must be adjusted to be activated (illuminate the LED light on the side) when the bolt of the
hard stop makes contact with the hook assembly. Loosen off the jam nut. Turn the body backwards until the
LED light on the side of the proximity switch shuts off . Turn the body forward again until the light illuminates.
Turn forward 1/2 turn more. Tighten the jam nut.
f) When the adjustment is complete, return the restraint to the parked position by turn the 3-position selector switch
back to the “DISENGAGE” position to take the controls out of Maintenance Mode.
g) Test the unit and repeat if necessary. Re-install the weather seal if it was removed.
