1. Basic Functions and Specifications

1. Core Functions

• Operation Control: Regulates door curtain lifting/lowering speed (standard range: 0.6–1.2 m/s) via a frequency inverter or PLC module.

• Limit Positioning: Utilizes an encoder or mechanical limit switch to precisely set open/close positions. Encoder-based systems retain settings during power outages.

• Mode Switching: Supports manual (for debugging) and automatic modes (with adjustable delay closure: 0–60 seconds).

2. Technical Parameters

• Power Supply: AC220V±10% or AC380V (must match door power requirements).

• Compatibility: Interfaces with radar, vehicle detection loops, infrared sensors, and safety light curtains.

2. Operation Procedures

1. Manual Mode

• Debugging Steps:

• Emergency Operation: Use the manual override handle/chain during power outages.

1. Switch to manual mode; use “UP/DOWN/STOP” buttons to adjust the door position.

2. Configure limit switches or encoder parameters via the control cabinet’s internal menu.

2. Automatic Mode

• Door ascends to the upper limit, then closes after a preset delay (default: 0–60 seconds).

• Curtain rebounds upon detecting obstacles (via infrared or light curtains) and retries closure after a delay.

• Triggers: Activated by radar, vehicle detection loops, or infrared sensors.

• Logic:

3. Safety Mechanisms

1. Anti-Crush Protection

• Infrared Detection: Stops and reverses the door if an obstacle interrupts the infrared beam during descent.

• Safety Light Curtain/Edge Sensor: Halts operation upon detecting obstructions beneath the door.

2. Interlock Function

• Prevents simultaneous opening of linked doors (e.g., in dual-door systems).

4. Troubleshooting

1. Door Unresponsive

• Verify power supply and reset the inverter if overloaded.

• Inspect terminal connections for looseness or short circuits.

2. Limit Malfunction

• Encoder Mode: Check wiring and recalibrate limits via the encoder setup.

• Mechanical Limit Mode: Adjust switch travel or replace damaged contacts.

3. Button Failure

• Test button circuits for breaks or replace faulty buttons.

5. Maintenance

1. Routine Checks

• Monthly: Inspect limit accuracy, sensor sensitivity, and lubricate tracks.

• Clean tracks and curtains to prevent debris buildup.

2. Component Lifespan

• Inverter/PLC: Replace after ≥500,000 start-stop cycles.

• Brake Pads: Replace if thickness falls below 2 mm.

Critical Notes

1. Safety: Do not pass through or linger near the door during operation.

2. Emergency Override: Use manual chains or cranks in emergencies.

3. Non-Experts: Avoid disassembling internal circuits without qualified personnel.
