FEATURES
INTRODUCTION
The GEMINI 220 V sliding gate system is a self contained unit which
comprise of a single 220 Volt AC electrical motor that drives the rack pinion
via a gearbox. The gearbox, electrical motor and associated components
are mounted in a rust treated base box. The base box is secured to the
base plate, which in turn is cemented or bolted to a concrete base. The
complete unit is enclosed with a weather resistant lid.
The GEMINI system is rigidly build for reliability, but with safety as first
priority. The electronic control card in conjunction with the limit switches
makes provision for the several unique features, such as remote controlled
gate opening, pedestrian opening facility, obstruction (“impact”) sensing,
adjustable “auto close” facility, infra red obstruction sensing facility
(optional) and normal push button operation.

WARNINGS
NEVER WORK ON THE SYSTEM WITH THE ELECTRICAL POWER ON.
NEVER ALLOW PERSONS OR ANIMALS TO STAND ON THE GATE OR
TRACK WHILE THE GATE IS IN MOTION.
KEEP HANDS CLEAR OF THE RACK AND PINION GEAR WHILE THE
MOTOR IS IN OPERATION.
DO NOT ALLOW ANYONE TO PUT THEIR HAND THROUGH THE GATE
TRELLIS WHILE GATE IS MOVING.
TEST ALL OPERATING SYSTEMS ON A REGULAR BASIS,
ESPECIALLY THOSE RELATED TO THE SAFETY FEATURES.

INSTALLATION OF THE UNIT
INITIAL PREPARATIONS FOR MOUNTING THE BASE PLATE
To determine the position for installing your GEMINI, fully close the gate
and place the unit (with base plate attached) in position so that the pinion
gear is approximately 15 mm away from the gate. Locate the base plate
against the existing gate track (the base plate is to be welded to this track
at a later stage).
NOTE
The securing holes in the base box are slotted; ensure that
the base plate bolts are located in the center of these
holes and that the base box and base plate are parallel.
Ensure that the centerline of the gate is parallel with the centerline of the
pinion. This will ensure that the centerline of the rack will run on the
centerline of the pinion.
Clearly mark the position of the base plate. Remove the complete unit and
prepare a foundation for the base plate. Consult your local Builders Supply
Store for the necessary information on concrete strengths, mix ratios and
hardening times.
NOTE
Install conduit piping in the foundation to correspond with
the opening in the base box, through which the electrical
cables are routed.
Remove the base plate from the unit.
Cast concrete into the previously prepared foundation. Ensure that the
exact position (previously marked) is maintained to ensure correct
mounting of the unit.
Stitch weld the base plate to the existing gate track.
Mount the GEMINI on the base plate and align as previously described.

MOUNTING THE RACK
Starting at one end of the gate, weld the rack in position by using the angle
iron brackets. The following critical points must be considered:
When determining the position of the rack, the manual override
lever must be in the upright position.
The angle iron brackets must not be more than 600 mm apart.
Allow a free play of approximately 1 mm between the pinion and
the rack.
When moving the gate to the next position, the manual override
lever must be lowered.
For wooden gates, drill two holes in the angle iron bracket and
secure to the gate with wood screws. To prevent the gate from
burning, mark the position of the angle brackets and weld to rack
before securing to the gate.
Once the rack is in position, ensure that the unit (pinion) is correctly aligned
with the rack. Final adjustments can be made by sliding the unit in the
slotted holes to achieve the correct alignment. Tighten the mounting nuts.

CONNECTING THE 220 V ELECTRICAL SUPPLY
CAUTION
Under no circumstances must the main electrical supply
be wired directly from a power source. As a safety
precaution, an ON/OFF switch must be incorporated into
the electrical circuit, normally within 1 meter from the unit.
Electrical power supply - Connect to the two terminal blocks
marked: 220V MAINS.
Ground (earth) connection - Connect the ground (earth) wire to
position marked: GRND.

OTHER CONNECTIONS
220 V Light - Connect to terminal blocks marked:
220 V LIGHT. Light will be activated when the
gate is opened and switches off ± 3 minutes after
the gate has closed.
Pedestrian Facility - Connect to terminal blocks marked:
COMMON and PED.
Push button - Connect to terminal blocks marked:
COMMON and TRIG.
Infra red sensor - Connect to terminal blocks marked:
COMMON and I/R BEAM.
Loop detector - Connect to terminal blocks marked:
COMMON and TRIG. (Depending on
Application)
Receiver - Plug in on electronic control card where marked:
RX IN.
External LED Connect to electronic control card as illustrated
CAUTION
Ensure that all the legal requirements for your local area
are complied with.
SETTING THE REMOTE CONTROL SECURITY CODE DIP SWITCHES
Once the electrical supply is correctly connected, the remote control
transmitter and receiver security code must be set. Note that the
manufacturers set all the transmitters and receivers to a standard code and
therefore it is imperative to change these codes to your own personalised
code.
If a non-Gemini remote control is used, program the remote control as per
the supplier’s instruction.
Programming a GEMINI Remote Control
Using a small screwdriver, remove the rear covers from the transmitter and
receiver. Place the units so that the numbers on the dip switches starts with
No. 1 from the left.
