limit switches
3) Typical conduits required at the control panel
a) High voltage wires: (120, 208, 240) single
phase or (208, 240, 480) three phase
Note: 120 VAC not available on 2HP models
b) 2” conduit to the hydraulic post(s) for hoses.
c) 3/4” conduit to the post(s) for limit switches.
d) Access control wires (Keypads, telephone
entry systems or any access control devices)
e) Loop wires for vehicle detectors
f) Other accessories such as warning lights etc.
4) Mount or install all control wiring such as
loops, access control, and entrapment
protection sensors. See detailed instructions
5) Pull and connect all wires and hydraulic hoses
a) Pull four wires, 18 gage minimum, for the limit switches from control panel to
junction area in the base of the operator post(s). This may be either by
underground conduit or by a seal-tight conduit into the side of the base.
b) Remove the lower cover (at 2’ height) on the post(s) to expose the limit
switches and connect the limit switch wires. The open limit switch is on the
left and lower than the close limit. Connect these wires to the control box at
the five pole terminal strip marked open limit and close limit.
c) HRG operators normally do not ship with the hydraulic hoses included, until
the exact length is specified by the installer. See page 14 and verify the
correct length before ordering.
d) For protection, tape the ends and pull the hoses through the 2" conduit from
each post to the controller box. Connect the hoses to the couplings, being
certain to match the color coded ends. Also be certain that the connectors
are firmly snapped together.
e) Remove the blue plastic shipping plug on the pump and replace it with the
vent cap that is provided.
f) Connect the electrical power wiring to the loose wires from the On/Off
switch and a grounding wire to the lower left corner of the electrical panel.
Be certain to the labeled voltage and phase of the operator matches the
available supply. Also be certain to oversize the branch circuit wires to allow for voltage drop,
especially for single-phase machines. See the wire size schedules in the appendix. Machines to
operate on high voltages (above 120 VAC) do not need a neutral wire.
g) Verify that the primary tap of the control transformer is connected to match the supplied voltage.
It is especially important to distinguish between 208 and 230 volt supplies. The various voltage
taps are identified by a label on the transformer.
6) Test and Adjust the Operator (See Smart Touch Setup First)
a) Test basic functions of the operator first, before connecting any external control wiring. If your
operator is equipped with vehicle detectors, be certain that they are connected to a loop or
unplugged so that they do not cause interference with the function of the machine. If the motor
turns, but nothing moves, reverse two poles of a three phase power source. Also check that the
by-pass valve is closed. Push in the round black knob that is located on the right side of the pump
manifold. Also be certain that the hose quick connectors are firmly engaged.
b) After testing the basic functions, add accessories and external control wiring. Fully test the
operator functions again.
