Apply lubricant to the door rollers, tracks, and hinges to reduce friction and prevent premature wear.
Ensure that the drive belt or chain is well-lubricated for efficient operation.
3. Safety Inspection:
Conduct routine safety inspections to ensure that motion sensors, presence sensors, and safety sensors are working correctly.
Check the safety features like automatic reversal and emergency stop functionality.
4. Belt/Chain Tension:
Inspect the tension of the drive belt or chain and adjust it as needed to prevent slack or excessive tension.
5. Electrical Components:
Examine wiring and electrical connections for signs of wear or damage.
Check the power supply and voltage to ensure consistent operation.
6. Remote Controls and Access Systems:
Test remote controls and access systems to verify that they are functioning correctly.
Replace batteries in remote controls as needed.
Troubleshooting Automatic Sliding Door Controllers
Despite regular maintenance, issues with automatic sliding door controllers may arise. Here's a troubleshooting guide to address common problems:
