This document is an installation and maintenance manual for "Swing Gate Operators" manufactured by Nice Australia under the GDS brand. The specific models covered are GDS 4, 6, and 7. These operators are designed for opening and closing swing gates or doors and are made in Australia using both Australian and quality imported components, including a Delta VSD (Variable Speed Drive).
Function Description
The GDS swing gate operators are automated systems designed to control the opening and closing of swing gates. They utilize a Variable Speed Drive (VSD) for smooth and controlled operation. The system includes a control board (CB-6) that manages motor functions, safety inputs, and various operational modes. The operators are capable of handling both single and dual gate installations.

Electrical Requirements:
- Power Supply: 240VAC single phase on the Control Box side.
- Motor Cabling: 1 x 3 core plus earth 1.5mm 3 phase shielded motor cable to each operator. Motor is connected in Delta configuration. Cable shield must be connected to earth at both ends.
- Limit Switch Cabling: 1 x 3 core 0.5mm (min) control cable for limit switches to each operator. Wiring should preferably be shielded if runs are over 8m or near 240V cabling to avoid interference.
- Control Input/Output Cabling: Control input cables, output signal cables, and lock cabling should also be shielded if long or near 240V lines.
- RCD Protection: To conform to RCD regulations and reduce nuisance tripping, a super immune type RCD (e.g., Clipsal 4 series) may be required. The VSD's internal filter circuit may need deactivation if false trips persist, as VSDs inherently produce low current leakage to earth (around 3mA +/-).
- Earth Leakage: Protective earth must be adequately sized and tested to ensure resistance no greater than allowed in AS/NZS 3000:2018 to reduce touch voltage potential on metal surfaces.
- VSD (Inverter): Highly sensitive to "dirty power" or modified sine waves. Portable generators are explicitly forbidden for use, even during commissioning, due to potential damage. High-quality UPS systems producing a pure sine wave can be used.
Control Board (CB-6) Features:
- Inputs: P.E (Photo Electric), OPN (Open), STP (Stop), CLS (Close), OSC (Open/Stop/Close), PED (Pedestrian). P.E, OPN, and STP require normally closed contacts and should be shorted to COM if unused. CLS, OSC, and PED require normally open contacts. Inputs require switch contacts only; no voltage should be supplied directly to the control board. IM-1 modules are available for isolating 12/24V inputs or long wiring.
- Outputs: Lock output (12V, max 30V AC/DC @ 5Amps), Light relay module (optional, max 240V AC / 30V DC @ 10 Amps).
- Powering Accessories: 24V AC supply available from the transformer output for accessories, but current capacity must be checked. This supply should not be used to power accessories that could interfere with the control board's operation.
Usage Features
Installation:
- Mounting: Operators are mounted to a gate rail, wall, or post. A level line from the top of the gate rail determines the mounting position. Mounting plates should be welded to steel posts with strengthening brackets if needed. For masonry, chemical anchors are recommended. Spacers (washers/nuts) may be needed between the wall and operator if no mounting plate is used to allow for the cover.
- Arm Positioning: When the gate is fully closed, the operator arms should be positioned approximately 10-15° off straight (around 165° between arms).
- Gate Bracket: The gate bracket is fixed to the gate rail, ensuring both arms are horizontal and level. The gate should be fully opened to verify adequate side room for arm swing.
- Cabling: Electrical cabling crossing driveways (for dual operators or single operators on the opposite side to the control box) must be run in conduit at correct depths for both mains and low voltage cables.
Commissioning:
- Initial Setup: Position the gate halfway, loosen the manual release knob until the clutch slips if the gate hits a stop too hard.
- Direction Setting: Power up the board. The first pulse should open the gate, and the GREEN LED (top right) should flash. If not, reverse two motor wires.
- Limit Switch Adjustment: Adjust cams so the gate stops precisely in the fully open and closed positions. Limit switches should activate just before the gate reaches its physical stops, allowing the torque limiter to operate.
- Dual Gates: For dual gates, disconnect one side's limit wires or position both cams on limit switches to adjust one side at a time.
- Travel Time Setting: Use the run/set switch (mode selection 1) to "set" mode. Run the gate from full open or closed by pressing OPN or CLS buttons. Hold the button for the full travel distance plus approximately 5 seconds after the gate stops. This must be done for both open and close cycles.
- Torque Limiter: After setting travel times, tighten the manual release knob and verify the torque limiter slips if an obstruction is present, while still providing enough drive for environmental conditions.
- Safety Devices: Confirm all safety devices (e.g., Photo Electric Cells, Induction Loops) and external locks function as designed.
Mode Selection (via DIP Switches):
- Synchronising Delay (Position 1):
- OFF: No delay.
- ON: Motor 1 opens 2 seconds before Motor 2; Motor 2 closes 2 seconds before Motor 1.
- Pulse Lock Output (Position 2):
- OFF: Lock output active for the entire motor drive cycle.
- ON: Lock output pulses for 0.3 seconds at the start of each drive cycle.
- Light Outputs Warning (Position 3):
- OFF: Optional light module controls a light with a 60-second timer.
- ON: Optional light module controls a warning light that activates when motors are on.
- Swipe Mode (OSC Input) (Position 4):
- OFF: OSC input has standard Open, Close, Stop action.
- ON: OSC input only opens the gate and resets the P.E. triggered auto-close mode.
- M2 Outputs Status (Position 5):
- OFF: M2 output controls the second motor.
- ON: M2 output controls status lights.
- P.E Stops Close Cycle (Position 6):
- OFF: P.E. input during closing causes motors to reverse.
- ON: P.E. input during closing causes motors to stop but not reverse.
- P.E Stops Open Cycle (Position 7):
- OFF: P.E. input during opening is ignored.
- ON: P.E. input during opening causes motors to stop.
- P.E Triggered Auto Close (Position 8):
- OFF: Not selected.
- ON: Selects P.E. triggered auto-close mode (0 seconds delay).
- Pedestrian Auto-Close (Position 9):
- OFF: No pedestrian access auto-close.
- ON: Selects auto-close in pedestrian access mode (15 seconds delay).
- Standard Auto Close (Position 10):
- OFF: Not selected.
- ON: Selects standard auto-close mode after full opening (30 seconds delay).
Setting Cycle Timers & Auto Close Times:
- The control board has pre-set cycle times (60 seconds for open/close, 5 seconds for pedestrian access).
- To adjust:
- Place the slide switch into the "set" position.
- Press and hold the desired push button (OPEN, CLOSE, or PEDESTRIAN) for the desired time. The OPN status LED flashes at 1-second intervals to assist.
- Repeat for other timers if needed.
- Place the slide switch back into the "RUN" position.
- Test operation.
- When setting OPEN and CLOSE cycle times with limit switches, release the push button a few seconds after the limit switch cuts motor power to allow for motors to slow down over time without re-adjustment.
Manual Release:
- Turn off and isolate power to the control box.
- Open the side door on the gate operator cover with the key.
- Turn the knurled disc anticlockwise to release the arm from the gearbox.
- If a magnetic lock is fitted, turn off power. If an electric lock is fitted, use the provided key to release it.
- The gate can now be opened manually. Ensure it is held firm.
- To re-engage drive, turn the knurled knob clockwise until tight. Close and lock the cover door.
