GENIUS LYNX 03 / LYNX 04 Control Board

1. General Characteristics

This control unit, powered by a high-performance microprocessor, is designed for 24 Vdc automatic barriers, offering a wide array of functions and adjustments, including deceleration and motor control. A sophisticated electronic control system continuously monitors the power circuit and disables the unit in case of malfunctions that could affect the electronic clutch's efficiency. Main settings and function modes are configured via dip switches, while timing and motor power are adjusted through a self-learning process during installation. Eight built-in LEDs provide constant status indication for both the control unit and the gearmotor.

2. Technical Specifications

Attention: Output values for 24V~ may vary based on mains voltage. Always verify the transformer output voltage before starting. It should not exceed 26V~ for either 230V~ or 115V~ power supplies. Voltage must be measured with no load connected.

3.1 Fitting the Buffer Batteries

Observe the following instructions for fitting optional buffer batteries (refer to Fig. 1):

1. Place the battery support (Ref. A) behind the fastening cross piece of the spring (Ref. B) and secure it with the provided M5 screws.

2. Position the batteries (optional) and secure them with plastic clamps if necessary (not supplied).

Note: The support is designed to house 2 batteries with the specifications detailed in paragraph 2.

[Diagram Description: Fig. 1 shows a diagram illustrating the placement of a battery support (A) behind a fastening cross piece (B) for battery installation.]

4. Connections and Operation

4.1 Terminal Board M1

• 4.1.1 24V power supply: Terminals "1-2" are for connecting the transformer's secondary winding (24 V~ 50/60 Hz). The POWER LED lights up when power is supplied.
• 4.1.2 Batteries: Terminals "3-4" are for two optional buffer batteries (minimum specifications in paragraph 2). The control unit charges batteries when powered. Batteries operate when transformer power fails; operation count depends on battery quality and load. Observe battery polarity.
• 4.1.3 Accessories: Terminals "5-6" provide 24 Vdc output for external accessories (max load 500 mA). Observe power supply polarity.
• 4.1.4 Gearmotor: Terminals "7-8" connect to the 24Vdc 80W max gearmotor.

4.2 Terminal Board M2

• 4.2.1 Earthing: Terminal "9" connects the mains earth cable. This is essential for correct operation.
• 4.2.2 Opening limit-switch: Terminals "10-11" connect the opening limit-switch. The FCA LED indicates its status. Function depends on dip-switch 3. Use a jumper if not used.
• 4.2.3 Closing limit-switch: Terminals "10-12" connect the closing limit-switch. The FCC LED indicates its status. Function depends on dip-switch 3. Use a jumper if not used.
• 4.2.4 Flashing lamp: Terminals "13-14" connect a 24 Vdc 15W max flashing light. It indicates programming phases (0.5s pre-flash on opening, 1.5s on closing). In automatic logic, it stays lit for 5s at opening stop. It turns off at closing stop or after 10s if safety devices are engaged.
• 4.2.5 Indicator-light/Courtesy light: Terminals "13-15" are for a 24Vdc 15W max lamp, parallel to the card's lamp-holder. Function depends on dip-switch 7.

4.3 Terminal Board M3

• 4.3.1 Close: Terminals "16-21" (CLOSE LED) connect devices for total gate closing via contact closure.
• 4.3.2 Start: Terminals "17-21" (START LED) connect devices for gate opening/closing pulses. Operation mode set by dip-switch 5.
• 4.3.3 Closing Photocells: Terminals "18-21" (FTC LED) connect safety devices (photocells, safety edges) to protect closing motion via contact opening. Use a jumper if no safety devices are connected. Connect NC contacts in series for multiple devices.
• 4.3.4 Stop: Terminals "19-21" (STP LED) connect devices (push-button, pressure switch) to stop gate movement via contact opening. Cycle restarts with a new opening/closing pulse. Use a jumper if no STOP devices are connected. Connect NC contacts in series for multiple devices.
• 4.3.5 Opening Photocells: Terminals "20-21" (FTO LED) connect safety devices (photocells, safety edges) to provide safety during opening motion via contact opening. Use a jumper if no safety devices are connected. Connect NC contacts in series for multiple devices.

5. Fitting a Remote Control Receiver Card

The control unit is designed to house a 5-pin radio-receiver module. To install, turn off power and fit the module onto connector M5 inside the unit. Ensure correct orientation as per paragraph 9 (Connection layout) to avoid damaging the receiver. After installation, follow the receiver's instructions for storing remote controls. A stored remote control acts as a START command device.

6. Control LEDs

N.B.: LED status shown in bold when automated system is closed and control unit is powered.

7. Programming

NB: Programming must be performed with the control unit powered off the mains, using the transformer. It is not possible to program using only buffer batteries. This ensures correct programming of all times and functions. Programming of work times, deceleration, and electronic clutch is done via self-learning. During this stage, leaf movement is at slow speed.

Procedure:

1. Release the automated system, move it to approximately midway through its opening travel, and then lock it.
2. Power up the control unit (the POWER LED will indicate power is on).
3. Turn switch S2 to PROG. The flashing lamp will turn on steadily to signal programming mode.
4. Press the push-button connected to the START terminals or use the remote control (if data is stored). The first operation the automated system performs must be CLOSING.
5. If the system moves to open, touch the two RESET pins with a screwdriver. The control unit will immediately stop the movement.
6. Cut power to the control unit, reverse the polarity of the two cables powering the motor, and repeat operation from point 1.
7. After the START command, the automated system moves to close until it reaches the closing stop or limit-switch.
8. After approximately two seconds, the automated system automatically restarts opening until it reaches the opening stops or limit-switch.
9. The control unit begins counting the pause time. Once the required time has elapsed, press the START command again, and the automated system will close completely.
10. Programming is now finished. Turn switch S2 back to OFF; the flashing lamp will turn off.
