4. Setup and Installation
Installation of the DITEC LCU40H control unit must be performed by a certified professional. Refer to the detailed wiring diagrams provided with the product packaging for specific connections.
4.1. Mounting the Control Unit
- Choose a suitable location for the control unit, ensuring it is protected from direct weather exposure and easily accessible for maintenance.
- Mount the unit securely using appropriate fasteners. The dimensions are 357 x 238 x 120 mm (H x W x D).
4.2. Electrical Connections
Ensure all power is disconnected before making any electrical connections.
- Power Supply: Connect the main power supply (230 VAC) to the designated terminals.
- Motor Connections: Connect the 24V DC motors to the respective motor output terminals. The unit supports up to two motors.
- Safety Devices: Connect all required safety devices, such as photocells, safety edges, and emergency stop buttons, to their dedicated inputs.
- Command Devices: Connect command devices like push buttons, key switches, or radio receivers.
- Accessories: Connect any optional accessories such as flashing lights or courtesy lights.
4.3. Initial Configuration and Auto-Learning
The Entrematic LCU series features an advanced auto-learning procedure for easy setup.
- After all connections are made, power on the unit.
- Follow the on-screen prompts on the integrated display to initiate the auto-learning process.
- The system will automatically detect and configure the gate's travel limits, acceleration, and deceleration parameters.
- Verify that the gate operates smoothly and correctly after the auto-learning process is complete.
5. Operating Instructions
The DITEC LCU40H control unit allows for flexible operation of your automated gate system.
5.1. Basic Operation
- Opening/Closing: Activate the gate using a connected command device (e.g., remote control, push button). A single command typically cycles the gate (open-stop-close-stop).
- Stopping: During gate movement, a second command will stop the gate.
- Reversing: If an obstacle is detected during closing, the gate will reverse its movement to ensure safety.
5.2. Advanced Settings (via Display)
The integrated display allows for fine-tuning of various parameters:
- Acceleration/Deceleration: Adjust the ramp-up and ramp-down speeds for smoother gate movement.
- Start/Stop Space: Configure the distance over which acceleration/deceleration occurs.
- Reinforcement Space: Set the distance for increased force at the beginning of movement.
- Pairing Speed: Adjust the speed at which the gate approaches its open and closed limits.
- Operating Modes: Select different operating modes (e.g., automatic closing, pedestrian opening).
Refer to the detailed programming manual (separate document) for specific menu navigation and parameter adjustments.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your gate automation system.
6.1. Routine Checks (Monthly)
- Visual Inspection: Check the control unit casing for any signs of damage, corrosion, or water ingress.
- Cable Connections: Verify that all electrical connections are secure and free from fraying or damage.
- Safety Devices: Test all safety devices (photocells, safety edges) to ensure they function correctly and stop/reverse the gate when activated.
- Gate Movement: Observe the gate's movement for any unusual noises, jerky movements, or signs of mechanical stress.
6.2. Professional Servicing (Annually)
It is recommended to have the system inspected and serviced by a qualified professional at least once a year. This includes:
- Thorough inspection of all electrical components and wiring.
- Checking and adjusting motor parameters if necessary.
- Lubrication of mechanical parts of the gate.
- Software updates if available.
Note: Always disconnect power to the control unit before performing any maintenance.
7. Troubleshooting
This section provides guidance for common issues. For complex problems, contact a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Gate does not move. | No power supply; Safety device activated; Remote control battery low; Motor fault. | Check power connection and circuit breaker; Inspect safety devices for obstructions or misalignment; Replace remote control battery; Consult a technician for motor inspection. |
| Gate stops unexpectedly. | Obstacle detected; Safety device fault; Overload protection activated. | Remove any obstacles; Check and clean safety devices; Allow unit to cool down if overloaded, then reset. |
| Gate opens but does not close. | Safety device (e.g., photocell) obstructed or misaligned. | Check photocells for obstructions or dirt; Ensure they are correctly aligned. |
| Remote control not working. | Battery low/dead; Not programmed correctly; Interference. | Replace battery; Re-program remote control (refer to remote manual); Check for sources of interference. |
The LCU40H features a datalog via micro SD and dedicated software, allowing analysis of the chronology of the last alarms, significantly facilitating the identification of anomalies and maintenance.
