CT INVERTER AM CONTROL UNIT

1. Introduction

The single-phase control unit CT INVERTER AM is a device suitable for operating and controlling sliding gates in an easy and complete manner. It is designed to satisfy all possible needs.

The onboard inverter allows setting maximum torque limits and modifying the frequency (motor speed). The possibility to use motors with encoders enables the unit to detect possible obstacles and reverse its direction of motion. It is suitable for commanding and controlling automatic accesses with its single-phase motor, 230Vac, max 1.5KW (current limited to 10A), WITHOUT using a starting capacitor.

Every control board is equipped with a memory module that stores all personal settings and parameters needed for operating the control board. These data can be transferred from one unit to another.

It is equipped with inputs for self-tested photocells, keys for SS (step-by-step), PED (partial opening), OPEN and CLOSE, switch limits, security stops, and a wide display with 3 keys for settings. It is also equipped with a molex connector for a plug-in receiver, output for courtesy and flashing light. It is possible to connect an additional card (R1) to operate an electric lock.

WARNING: DO NOT INSTALL THE CONTROL UNIT WITHOUT READING THE INSTRUCTIONS FIRST!

4. Preliminary checks

These checks must be performed by professionals. Correct wiring of the motor and limit switches is crucial.

1. Unlock the motor and supply power only after checking wiring and absence of short circuits. Check input LEDs: normally closed inputs should have their corresponding LED lit.
2. Manually move the gate to the total opening position. Check LS.OP LED: OFF is correct; ON (with LS.CL OFF) indicates a limit switch connection issue.
3. Manually move the gate to the total closing position. Check LS.CL LED: OFF is correct; ON (with LS.OP OFF) indicates a limit switch connection issue.
4. Manually move the gate to the middle of the run and lock the motor. Enter 'Manual Movement' in MENU B and command closure. WARNING: Pay attention to the moving gate! Check motor rotation: if it opens, stop, reverse motor connections, and try again. If it closes, proceed to the next step.
5. Manually move the gate to the middle of the run and lock the motor. Enter 'Manual Movement' in MENU B and command opening. WARNING: Pay attention to the moving gate! Check motor rotation: if it closes, stop, reverse motor connections, and try again. If it opens, proceed to the next step.
6. Once all operations are successful, close the automation and lock the motor.

5. Manual motion (Menu B - Manual movement)

This operation is for installation personnel only and requires maximum attention. Photocell and safety edge are not monitored during this phase.

Access 'Manual Mov.' in MENU B, confirm with P2. Move the gate using P1 and P3. Exit by pressing P2 or waiting 15 seconds.

6. Learning

6.1 Learning the run of the gate (Menu B - Final position)

This defines the gate run parameters (width, normal speed, slowed speed). Adjust torque and speed before learning. Ensure the gate is closed before starting.

1. Enter 'Final Position' in MENU B, confirm with P2.
2. Start gate movement with P1 (START) or Step-by-Step key.
3. Push P1 or Step-by-Step key to set the slowdown point for opening.
4. Gate moves at reduced speed until the opening limit.
5. Gate starts closing. Push P1 or Step-by-Step key to set the slowdown point for closing.
6. Gate moves at reduced speed until the closing limit. Programming terminates upon reaching the closing limit.
7. If no slowdown zones are set, factory settings are used.
8. Exit the menu by scrolling to EXIT.

6.2 Learning the partial run (Menu B - Ped. Position)

Defines the partial opening position for pedestrian access (PED command). Adjust torque and speed first. Ensure the gate is closed before starting.

1. Enter 'Ped. Position' in MENU B, confirm with P2.
2. Start gate movement with P1 (START) or Step-by-Step key.
3. When the gate reaches the partial opening position, push P1 or Step-by-Step key.
4. Gate moves in closing. Programming terminates when the gate hits the closing limit.
5. Exit the menu by scrolling to EXIT.

7. Adjustment of the speed and the torque (Menu B - Speed and torque)

These parameters allow adjustment from minimum to maximum values. Consider gate dimensions and weight. High speeds and torques can be dangerous. Adjustments must be made by professionals. Check functioning after any regulation. Re-learn the runs whenever parameters are changed.

8. Advanced functions

These are functions and modalities activated via the programming menu:

• Automatic closing: Timed closing from full or partial opening. The 'stop' command disables it until a new command is received.
• PhotoAutoReclose: Gate closes 3 seconds after photocell intervention in fully open or partial open position.
• Motor brake: For motors with high inertia requiring quick stops. Consider mechanical sizing. (OFF: disabled; 1: electronic brake; 2/3: external brake activation).
• Dead Man: Motor moves only with a permanent command. Opens with 'open' key pressed, closes with 'close' key pressed. Forbids automatic motion.
• Condominium: Commands only open the gate. Closing is via automatic closing function (must be activated).
• Inv. On photocells: If photocell beam is interrupted, gate reverses immediately (closing) or after obstacle removal (opening/closing).
• Photocell test: Controls photocell function before motor operation. Indicates faults by flashing and no motor movement.
• Edge Inv: If safety edge alarms, gate stops or stops and reverses (closing phase only).
• Edge Test: Functional test of the safety edge.
• Pre-flashing: Blinking command before each movement.
• Zone light: Auxiliary output as courtesy light or zone light (lit when gate is open).
• Auxiliary light timeout: Sets the delay for switching off the auxiliary light.
• Clock function: OPEN input becomes a clock input for programmed opening.
• Water hammer in opening: Advisable for electronic locks. Motor briefly operates in closing before opening when gate is closed to unlock the electronic lock.
• Encoder: Enables encoder functionalities. Control board operates by encoder instead of time. Detects motor blocking.
• Sensor level: Modifies sensitivity of the 'stop motor' sensor. Lower value for higher sensitivity.
• Sensor inversion: Defines gate reaction to 'stop motor' sensor. If not activated, gate stops. If activated, reverses shortly in opening or opens completely in closing.

9. RESET of the control board (Menu C - Reset)

Resets the control board to factory settings. All programming and personal settings must be repeated.

10. Backlighting of the display (Menu C - Display light)

Enable/disable display backlighting. The control board has an energy-saving function that automatically switches off the display after inactivity. Backlighting reactivates upon user operation.

11. Housing for radio receiver

The unit has a molex connector for an ALLMATIC radio receiver. The first channel is associated with the S.S. command, the second with the PED command. Follow receiver instructions for transmitter learning.

12. Auxiliary output (only with additional card R1)

The functioning depends on the 'Brake' parameter setting:

• Brake OFF-1: Normally open contact for electronic lock activation. Enable 'Water Hammer in opening' first.
• Brake 2-3: Contact for external brake activation.

Connection with the control unit R1 card:

• RELAY: 230 Vac 5A max, 30 Vdc 5A max
• ELECTRICAL LOCK, MOTOR BRAKE

9. Tips for a successful installation

9.1 High speed movements

• Problem: Motor stops due to effort, automation is easily stopped by counteracting movement, gate moves slowly despite high speed setting, or motor stops with FAULT/blinking display.
• Solution: Raise torque (High Torque OP/CL) or lower speed (High Speed OP/CL) as appropriate.

9.2 Low speed movements (slowing down)

• Problem: Motor stops due to effort, automation is easily stopped by counteracting movement, gate moves slowly despite high speed setting.
• Solution: Raise torque (Low Torque OP/CL) or lower speed (Low Speed OP/CL) as appropriate.

9.3 Correct working

The correct setting is when the automation cannot be stopped by counteracting its movement. Safety devices are essential for automation safety.

WARNING AND ADVICES

Avoid placing connection cables of buttons, security devices, and inputs close to power supply cables of the control unit and motor. Some parts of the control unit carry dangerous voltages. Installation and programming must be done only by qualified professionals. Always use a device ensuring disconnection of all poles of the control unit's power supply (e.g., a switch with a minimum contact distance of 3 mm per pole, or a device connected to the power network).

For connecting the card and motors, use double-insulated cables. Minimum conductor cross-section: 1.5 mm² to 2.5 mm².
