Configuring two operators to be a Primary
and Secondary pair is easy with the Smart DC
Controller. There is no need to order a special
model or any adapters. The area of the board
marked Dual Gate employs a 3-wire RS-485 serial
port for communication between primary and
secondary operators. See Figure 62.
POWER REQUIREMENTS
When installing a dual-operator system, the
following must be adhered to:
An electrical conduit for interconnecting wires
must span between the two operators. The dual
gate communication wires and any low voltage
control wires must be installed in a conduit that
is separate from the high voltage power wires.
See Figure 63.
Complete the installation of both operators as
separate machines and verify that their basic
functions are correct as solo operators before
interconnecting them.
BI-PARTING GATE SYSTEMS
External control inputs, vehicle detectors and
external entrapment sensors may be connected
to either gate operator without regard to
preference.
Be sure both operators are running the same
software version. The software version is
available on the display by pressing the RESET
button on the operator. The software version
appears beneath the word HYSECURITY. Keep
the most current software loaded. It is available
at www.hysecurity.com. Make it part of your
maintenance routine to check for software
upgrades on a regular basis.
Both operators can be connected to the same
20A circuit breaker in the main panel. The wire
size affects operator performance. Use the
following chart as a guideline to size wire for
the given distance from the power source to
BOTH operators.
