Technical Diagnosis Protocol
Automatic doors are complex electromechanical systems. In Dwarka Expressway, 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 Dwarka Expressway 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 Dwarka Expressway environments, interference can cause 'ghost opening'. We adjust the sensitivity potentiometers and alter the detection field geometry to ignore parallel traffic.
Brand-Specific Expertise in Dwarka Expressway
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 Dwarka Expressway 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 Dwarka Expressway 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.
Safety Standards (EN16005 Compliance)
Safety is paramount. In Dwarka Expressway, 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 Dwarka Expressway, acting as a fire escape.
Case Study: Recent Work in Dwarka Expressway
The Challenge: A busy shopping complex in Dwarka Expressway had a Dorma door stuck in the open position. Our team diagnosed a faulty radar sensor. We replaced it with a Bea Eagle 6 microwave sensor and recalibrated the closing speed. The door was operational within 3 hours.
The Result: Zero downtime and improved energy efficiency for the client.
Frequently Asked Questions
