THE CONCRETE OPERATOR PAD
Installation requires the presence of a suitable concrete pad as a base for
the operator. The dimensions of this pad should be sufficient to allow
at least 5" of clearance from each edge of the pad to the nearest
operator mounting hole. The top of the pad should be 3" above grade to
raise the operator above any standing water, while the depth of the pad
below grade is dependent on the weight and size of the gate and the soil
conditions at the site of the installation. The Tower cover is 34" high
and is removed by lifting it vertically off the operator. THE SITE FOR
THE OPERATOR SHOULD BE CHOSEN WITH AT LEAST 35" OF
CLEARANCE ABOVE THE TOP OF THE UNIT.
If no suitable concrete base exists, a pad must be poured. See Figures 5
and 6 for plans for this pad. Consult local building codes for depth of
base. Typical depths range from 24 to 36 inches. In either case, if
vehicles are going to be operated in the vicinity of the operator,
consider installation of protection posts in front of the operator.
If a suitable concrete base already exists for mounting the operator it
will be necessary only to drill mounting holes for the Tower. 3/4"
mounting slots are located on each flange of the operator mounting
angle pieces. Four redhead bolts, 3/8" or 1/2" in diameter, should be
used for mounting the operator. The bolt pattern for the Tower is 11-
1/2” wide x 4-1/8” deep on center (See Figure 6). The two rear bolts,
(closest to the gate), should be no closer than 4-1/2" from the near side
of the gate to allow sufficient clearance for the operator's
cover. The rear bolts should also be no farther than 8" from the gate if
the chain brackets provided with the operator are to be used.
ELECTRICAL POWER REQUIREMENTS
NOTE: Before connecting the operator, use a voltmeter to insure
that the electrical service is 115 VAC. Connection to 220 VAC
service is the most common cause of board failure in new
installations and is NOT covered by the warranty.
The Tower requires a 3-wire (Hot, Common, Ground), 115 VAC,
electrical circuit with a 15 Amp breaker for proper operation. In
installations with more than one operator, each operator must have a
separate service from the breaker panel. Powering multiple operators
from the same service can result in having to "de-sensitize" the
obstruction sensing adjustment to prevent one operator from
overloading the other. The electrical hookup is made in the junction
box located in the right front corner of the frame. See Figure 7, Page 7.
