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 6" 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 SITE FOR THE
OPERATOR SHOULD BE CHOSEN WITH AT LEAST 5" 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. 3/4" mounting holes are
located on each side of the operator. Four redhead bolts, 3/8" or 1/2" in
diameter, should be used for mounting the operator. The bolt pattern is
10" wide by 16-3/4" long. The two rear bolts, (closest to the gate),
should be no closer than 3-5/8" from the near side of the gate to allow
sufficient clearance for the operator's cover.
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 operator 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
