Technical Diagnosis Protocol
Automatic doors are complex electromechanical systems. In Khan Market, we often encounter issues that general electricians cannot fix. Our diagnostic process is rooted in engineering principles:
1. Controller Logic Analysis
Modern doors like the Dorma ES200 use a microprocessor to control speed and force. Common issues we see in Khan Market include 'Error 3' (Emergency Stop) or 'Error 9' (Motor Hall Sensor). We hook up a diagnostic terminal to read these fault codes directly from the board.
2. Motor Torque Testing
For Ozone S-Series motors, we test the armature resistance. If the DC motor is drawing excessive current, it indicates internal friction or a failing gearbox. We replace carbon brushes or the entire motor unit to prevent total burnout.
3. Sensor Frequency Tuning
Geze and Tormax sensors operate on microwave frequencies. In crowded Khan Market environments, interference can cause 'ghost opening'. We adjust the sensitivity potentiometers and alter the detection field geometry to ignore parallel traffic.
Safety Standards (EN16005 Compliance)
Safety is paramount. In Khan Market, we ensure all our installations meet international safety norms:
- Safety Beams: We install photocells at knee height to prevent the door from closing if a person or object is in the threshold.
- Reverse on Obstruction: We calibrate the motor's current limit. If the door hits an obstacle, it must instantly reverse.
- Battery Backup: We install battery packs to ensure the door opens automatically during a power failure in Khan Market, acting as a fire escape.
Brand-Specific Expertise in Khan Market
We are not generic handymen. We are independent specialists for specific architectures:
DORMA
We stock replacement tooth belts and carriage wheels for Dorma ES200 Easy and Variflex models. We also repair the transformer block which is a common failure point in Khan Market due to voltage fluctuations.
OZONE
Specialists in Ozone O-Series and Telescopic doors. We can retrofit an Ozone kit onto your existing manual glass door in Khan Market within 6 hours.
GEZE
Expert handling of Geze Slimdrive units. We perform the mandatory 'Teach-In' run after every rectification to recalibrate the opening width and braking distance.
Case Study: Recent Work in Khan Market
The Challenge: A factory in Khan Market needed a rugged solution. Their existing Geze door motor had burned out due to heavy wind load. We installed a high-torque motor and adjusted the hold-open time to improve logistics flow.
The Result: Zero downtime and improved energy efficiency for the client.
Frequently Asked Questions
Yes, we support legacy models. If parts are obsolete, we can retrofit a modern controller into the existing track.
Prices vary by technology (Infrared vs Microwave). Contact us for a quote in Khan Market.
Yes, our AMC includes quarterly visits, greasing, and priority breakdown support for malls in Khan Market.
This usually means the end-stop buffers are worn out or the belt tension is too loose. It needs immediate attention.
Yes, we can install electromechanical floor locks or magnetic locks integrated with the door controller.
