Diagnosing and fixing logic errors.
The powerhouse of your system in Hillingdon is the High-Torque Drive Unit. When these fail, you might hear excessive vibration. We diagnose specific faults like encoder positioning errors and replace the unit with OEM parts to restore smooth motion.
A snapping sound often indicates a worn toothed belt. In Hillingdon, we replace these with reinforced Kevlar belts that resist stretching. We also inspect the nylon rollers. Replacing worn rollers eliminates vibration, allowing the door to glide effortlessly.
False activations, known as phantom opening, are common in Hillingdon due to weather interference. We calibrate Optex sensors to ignore interference. Crucially, we test the active infrared safety beams to ensure the door never closes on a pedestrian.
