Installation
6. Install Grip Tape to Underside of Drive Rail
Two pieces of grip tape have been provided that should be installed on the underside of the drive
rail. Place the tape on the first and last 2 ft. of travel, just in front of each limit ramp. Be certain the
drive rail is clean and dry, and then peel off just a bit of the backing to expose only about 2" of the
adhesive. Attach the tape to the underside of the drive rail, within 1" of the front of the limit ramp.
Now that the tape is lined up, peel the remainder of the backing away and attach the full length of
the tape. Repeat this procedure for the other end of the drive rail.
7. Clamp the Drive Wheels to the Drive Rail
When the wheels are fully clamped on the drive rail, the
red spring should be compressed to 2" in height. If
adjustment is necessary, turn the nut at the bottom of the
threaded rod assembly. Slightly less compression is okay
for lighter gates. See Use of Manual Release on page 54
8. Electrical Power Connection
This operator is intended for permanent installation, so all
electrical conduits must be properly connected to the
control box. The entry for the primary power is a 1/2 - 3/4"
knockout on the left side of our control box next to the on-off
switch. When this operator was manufactured, it was built to
run on a specific voltage and phase for line power. Make sure
you have compared the line voltage and phase available with
the nameplate on this machine. They must match! Be certain
that the wire size of the branch circuit that will supply the opera-
tor vs. the distance of the run from the main panel is large
enough to avoid excess voltage drop. Also be sure the operator
is electrically well grounded. See the Appendix, page 63 for
correct wire sizes and detailed electrical wiring information.
9. Primary Tap of Control Transformer
(not on battery operators)
Check to make sure that the primary tap on the control trans-
former matches the line voltage you have connected to the
operator. Measure the line voltage carefully to distinguish be-
tween 208V and 230V branch circuits. A label on top of the
transformer identifies the various voltage taps.
10. Electrical Power for Two Part 333 type operators
The primary AC power must be routed to the controller enclosure with the pump, but there must
also be conduits between the gate operator and the controller enclosure.
Note: AC power is not needed in the gate operator, unless there is an optional heater. A minimum
of two separate conduits must be provided, 2" for the hydraulic hoses and 3/4" for the electrical
interconnections. Unless there are accessories in the gate operator, the only electrical interconnec-
tion between the two enclosures will be three wires between the two terminal strips for the limit
switches. Join the hydraulic hoses by plugging the quick coupling together according to the hand of
the gate. See the drawing in Section 8, page 60.
