GEMINI Motorised Opening System for Domestic Swing Gates

INTRODUCTION

It is worthwhile reading these instructions carefully and heeding the instructions given.

IT WILL SAVE YOU TIME, TROUBLE AND MONEY

This instruction book has been written to assist the owner in the correct installation, operating and maintenance procedures of your GEMINI to ensure continued reliability and a long life.

Before leaving the factory, each unit is thoroughly inspected and functionally tested. Although the unit has a factory guarantee, DMI ENGINEERING has done everything possible to ensure that your GEMINI is safe and reliable. The manufacturer cannot be held responsible for poor workmanship during installation.

Electrical connections and repairs must be carried out by qualified artisans to ensure that all the legal requirements for your local area are complied with.

Please heed all WARNINGS in this book for the safety of your children, animals and yourself.

Thank you for choosing GEMINI Motorised Opening System for Domestic Swing Gates. Be assured that your system was driven by safety as the design criteria. By following the basic principles of installation as explained in this manual, your GEMINI automation system will provide you with many years of trouble free service.

The GEMINI system is of rugged design and manufacture. It is built for reliability and safety. It consists of a master and/or slave motor, which drives arms to open or close the swing gate.

The GEMINI 24V DC Swing gate system is a self-contained unit, which comprises of a 24V DC electrical motor and batteries. The electrical motor and associated components are mounted in a rust resistant base. The base is secured to the pedestal, which in turn is cemented into a concrete base. The complete unit is enclosed with a weather resistant lid.

The electronic control card in conjunction with the limit switches makes provision for several unique features such as remote controlled gate opening, , pedestrian opening facility, obstruction {‘impact”) sensing, adjustable “auto close” facility, infrared obstruction sensing facility (optional), courtesy light facility, and normal push button operation.

WARNINGS

IMPORTANT SAFETY INSTRUCTIONS:

• NEVER WORK ON THE SYSTEM WITH THE ELECTRICAL POWER ON.
• NEVER ALLOW PERSONS OR ANIMALS TO STAND ON THE GATE WHILE THE GATE IS IN MOTION.
• KEEP HANDS CLEAR OF THE OPERATING ARMS WHILE THE MOTOR IS IN OPERATION.
• DO NOT ALLOW ANYONE TO PUT THEIR HAND THROUGH THE GATE TRELLIS WHILE GATE IS MOVING OR ABOUT TO BE ACTIVATED.
• TEST ALL OPERATING SYSTEMS ON A REGULAR BASIS, ESPECIALLY THOSE RELATED TO THE SAFETY FEATURES I.E. OBSTRUCTION SENSING AND IR BEAMS
• DO NOT ALLOW CHILDREN TO PLAY WITH THE CONTROLS.
• KEEP REMOTE CONTROLS AWAY FROM CHILDREN.
• IT IS MANDATORY TO INSTALL INFRA RED BEAMS OR SIMILAR SAFETY DEVICES IN SUCH A MANNER AS TO PREVENT OPERATION OF THE SYSTEM WHEN THERE IS A CHANCE OF THE GATES COLLIDING WITH A VEHICLE OR PERSON OR ANIMALS.

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:

220V Mains is supplied to the power supply unit (PSU). The 27V supplied by the PSU is connected to the harness.

Ground (earth) connection:

Connect the ground (earth) wire on the base plate.

Use a minimum of 1.5mm cable for the battery and motor connections and 0.5mm for the limit switches and common (LIM+COM)

STANDARD INSTALLATION KIT

YOUR GEMINI GATE OPENING KIT FOR SINGLE GATE APPLICATION COMPRISES OF THE FOLLOWING:

1. Motor carrier box

2. Post with mounting flange

3. Crank Arm

4. Connecting Arm with Adjustment Nut

5. Gate Bracket

INSTALLATION INSTRUCTIONS

PLANTING POSTS

Refer to Figure 1

The posts can be planted anywhere on the dotted line X – X shown in Figure 1, provided “C” does not become less than 150mm. Note that the posts are positioned so that the diagonal of the mounting flange corresponds with the line X – X to ensure the correct alignment of the motors when mounted. Also note that the height of the mounting flange above ground level should be at least 300mm. See below figure 3.

MOUNTING MOTORS AND BRACKETS

Refer to Figure 1 Illustration 2

The master motor can be mounted on either side of the gate. Complete all electrical connections and get the motors operational as per the wiring diagram. Do not connect the gate. See below Figure 4.

Activate the motors to rotate to the closed position. Mount the gate brackets onto the gate. See following page Figure 5.

As the crank arms are not locked onto rotating shaft at this stage, rotate them until they point to the gate bracket and measure the distance from the hole in the gate bracket to the end of the crank arm. See following page Figure 5.

Refer to Figure 1

Rotate the arm by 180º or to maximum open position. When the gate is opened to 90º or to the required open position, the distance between the hole in the gate bracket and the end of the crank arm should still be the same, as when in the “CLOSED” position. If not, shift the gate bracket and re-measure. See below Figure 5.

Once the ideal positions have been located, cut the connecting arm and weld onto adjusting nut. Weld gate bracket onto the gate and hook the connecting arm into the hole in the gate bracket. See below Figure 5.

The crank arm can now be locked by means of a 10mm Hexagonal key or other suitable means. See below Figure 5.

SETTING LIMIT SWITCHES

Refer to Figure 6 below

The close limit switch is not adjustable, but if all the previous stages have been followed to mount the connecting arm, it will not be necessary to adjust the close limit switch.

The open limit switch is adjusted by rotating the cam on the worm wheel (flip the control board on the master motor for access to the worm wheel).

REVERSING THE ELECTRICAL MOTOR DIRECTION

Refer to Figure 7 below

When the gate is initially activated (during installation) and the gate direction is incorrect, the gate direction dip switch must be moved to the opposite side.

This will ensure that both motors do not open at the same time and wedge the gates against each other.

OTHER CONNECTIONS

220V light| Connect the blue terminal block on the PCB marked LIGHT. The light will be activated when the gate is opened and switches off ±3 minutes after the gate has closed. The relay on the control board serves as a switch and will not supply any power.
---|---
Pedestrian facility| Connect push button to the green plug marked COM and PED marked on PCB
Push button| Connect to green plug marked COM and TRIG on PCB
Infra-red sensor| Connect to green plug marked COM and INFRA-RED marked on PCB
Loop Detector| Connect to green plug marked COM and TRIG on PC
Additional receiver| Plug in on electronic control card marked RECEIVER PLUG
Buzzer| Connect to the terminal block marked: -BUZZER+
Lock| Relay on board to activate this function. Connect To the terminal blocks marked LOCK

CAUTION: Ensure that all the legal requirements for your area are complied with.

PEDESTRIAN OPENING FACILITY

The Pedestrian Opening Facility can be utilised to give pedestrians access to the premises. The facility allows the gate to open and remain open for ten (10) seconds before automatically closing.

In the double swing gate application, the pedestrian facility will only open the master gate motor and automatically close after ten (10) seconds.

SELECTING THE DOUBLE OR SINGLE SWING OPTION (See figure 7)

Link IN (2 Motors) Select this option when a master and slave motor are used (two gates)

Link OUT (1 Motor) Select this function when only a master motor is used (single gate)

SETTING THE AUTO CLOSE DIPSWITCHES

After your GEMINI unit has been installed and you wish to alter the time delay for the auto close facility, proceed as follows:

0 = Off
1 = On

PROGRAMMING A GEMINI CODE HOPPING TRANSMITTER (REMOTE)

If a non-Gemini remote control is used, program the control as per the supplier’s instruction.

To learn the transmitters (Maximum of 30):

1. Press and hold transmitter (remote) button.
2. Press and release the learn button on the PCB.
3. Receiver LED on PCB will flash twice.
4. Release transmitter button after led flashed twice.
5. Repeat steps 1-3 for additional transmitters.

To erase all transmitters:

1. Press and hold the LEARN button for 10 seconds or until receiver LED turns off.

TROUBLESHOOTING GUIDE
