ELECTRICAL INSTALLATION INSTRUCTIONS
Pentalift Hydraulic Truck Restraint
packages are supplied in four separate components requiring electrical connection,
consisting of the power unit, control panel, outside signal lights, and the restraint device. Each item is internally wired at
the factory. They must all be connected to each other.
The following instructions apply to standard units:
1.
_
Carefully examine the restraint components and review the instructions and wiring diagram to determine the tools
and supplies that are required for proper installation.
2.
_
For new construction, conduits must be placed as per the appropriate Pentalift pit drawing. Confi rm the conduit
locations with the appropriate Pentalift pit drawing.
3.
_
Run the required wires from the control panel to the signal junction box (by others), restraint power unit junction
box, restraint power unit motor, and outside signal lights. Attach these wires to the appropriate terminal strips in the
control panel and in the various junction boxes.
4.
_
Ensure that the motor starter thermal overload is set to match the full load current as shown on the motor name
plate. Consult all applicable electrical codes.
5.
_
Connect the AC power supply line to the control panel.
NOTE: Power unit requires full voltage at motor. Wire size should be suffi ciently sized to prevent line voltage drop
when the motor is under load.
6.
_
With power to the control panel, turn the AUTO RETURN and SHELTER switches (if equipped) to OFF and
turn the ULTRAHOOK switch to DISENGAGE. Check the indicator lights located on the front face of the PLC. The
following indicators must be lit:
- PWR(Red LED)
- 0C “Hook Fully Retracted”(Green LED)
- RUN(Green LED)
- 0F “Maintenance Mode”(Green LED)
- 08 “Hook Fully Extended”(Green LED)
- 47 “Outside Green Light”(Green LED)
- 09 “4” from Dock Face”(Green LED)
- 41 “Inside Red Light)(Green LED)
7.
_
If these indicators are not lit as per step (6), check all connections before proceeding to ADJUSTMENTS AND
TESTING on page 14.
8.
_
Once the electrical connections are completed and the dock leveler is installed, cycle the restraint several times
to ensure there is suffi cient clearance, the unit is positioned properly and that all proximity switches, the tilt spring and
hard stops are adjusted correctly.
