9 - WIRING AND CONNECTIONS

Permanent wiring is to be employed for the installation as required by
local codes.
Use only U.L. listed (or equivalent) non-contact sensors. Inputs from the pho-
to-beam to the circuit board are Normally Open (N.O.). Use only U.L. listed (or
equivalent) non-contact sensors.
Connect the non-contact sensors. Inputs from the photo-beam to the circuit
board are Normally Open (N.O.). Photo-beam input shall REVERSE travel of
mal operation when photo-beam is no longer activated.

ments. The distance shown in the chart is measured in feet from the opera-
tor to the power source. If power wiring is greater than the maximum dis-
tance shown, it is recommended that a service feeder be installed. When
large gauge wire is used, a separate junction box must be installed for the
operator connection. The wire table is based on stranded copper wire.
Wire run calculations are based on a 110 VAC power source with a 3%
voltage drop on the power line, plus an additional 10% reduction in dis-
tance to allow for other losses in the system.

Figure 19 - GROUNDING WIRE
The gate operator should be grounded to a copper rod driven to a
minimum depth of 3 feet, and properly grounded to the opener using a ¼"
copper wire prior to operation. Ensure proper ground bonding by remov-
ing paint around the mounting hole to create a proper connection if required.

WARNING
This swing gate operator uses an inherent entrapment sensing system as well
as external type sensors.
WARNING: External entrapment protection must be added to insure a
safe vehicular gate operating system.
Entrapment protection must be provided by a combination of non-contact
inherent devices. Disconnect power to the gate operator before installing the
non-contact sensors.

One or more non-contact sensors should be located where the risk of entrap-

contact must be shorted to ground through a switch to open the gate. The
FAIL SAFE connector which is shorted at the factory with a jumper (Normally

Closed NC), may be wired in parallel with the Fire input to release the motor in
Opening the FAIL SAFE contacts allows the gate to be pushed open by hand
during a power outage.

10.2 - Fail safe connection

A "fail safe" electric motor brake is provide for each of the three motor control
outputs on the main gate control board. A jumper is installed at the factory
for the primary motor control as shown in the photo to activate this electric
brake. This jumper creates an effective brake action on the motor that does
not allow the gate to be operated (opened or closed) manually, whether or
not the gate operator is powered. This jumper may be removed during a
power outage to enable operation of the gate manually, or during installation,
the jumper may be removed and this connector may be wired to an external
switch for more convenient access. The fail safe jumpers for the Motor 1 and
Motor 2 control provide the same electric brake function for external gate
motors in alternative installation.
