DIALIGHT Product Lines We Repair
Our engineers are trained on the full DIALIGHT product range. Below are the major product families we service.
Dialight 70 Series Stack Lights
Compact modular stack tower units with individual LED modules (red, amber, green, blue, white) stacked to height. Common issues: LED module failure, internal connector corrosion in humid environments, loss of signal in one or more color modules, and base contact degradation.
Dialight 30mm Miniature Tower
Ultra-compact signal light for space-constrained machine control panels and DIN rail mounting. Prone to condensation inside lens, intermittent electrical contact loss, and LED burnout under voltage surges from unshielded motors.
Dialight Sounder/Audible Alarm Units
Integrated buzzer and LED signaling units for machine alarms and emergency stop indication. Repairs address solenoid chatter, speaker cone damage, LED circuit board faults, and 24VDC coil failure in continuous-duty applications.
Dialight Hazardous Location Enclosures
Zone 1/2 and Class I Division 1/2 rated stack light housing for explosive atmospheres in refineries and chemical plants. Repair includes sealing gasket replacement, internal PCB cleaning, flange tightening, and recertification of IP67 rating.
Dialight LED Module Cartridges
Individual plug-in color modules (RGB types) for modular towers. Common faults: LED chip solder crack from thermal cycling, internal resistor failure, and degraded lens optics reducing brightness in Indian high-temperature / high-humidity plants.
Dialight Control/Power Supply Boards
Electronic control PCBs for sequential flashing, timing logic, and 110/230VAC to 24VDC conversion in stack light systems. Repairs: capacitor bulging, relay contact fusion, microcontroller reset loops, and thermal runaway in switched-mode supplies.

Common DIALIGHT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DIALIGHT equipment arriving at our workshop.
- ✓LED module complete or partial brightness loss — Dialight LED cartridges in Indian manufacturing plants experience thermal stress from direct sunlight, high ambient heat in foundries/forges, and voltage transients from unfiltered motor circuits. Solder joints on LED chips crack, or phosphor coating degrades, reducing or eliminating light output.
- ✓Internal corrosion and contact resistance in signal tower base — Dialight towers installed in humid environments—textile mills, sugar plants, coastal refineries—accumulate moisture inside the base connector. Oxidation on contact pins increases electrical resistance, causing intermittent signal loss or no light despite correct 24VDC input.
- ✓Audible alarm sounder inoperative or weak sound output — Dialight sounder units used in noisy foundry and textile environments undergo fatigue of the solenoid coil windings and speaker cone. Continuous buzzing duty or shock from adjacent machinery can crack the voice coil or delaminate the cone, muting or distorting the alarm.
- ✓Intermittent or no signal in one color (red, green, amber) — In modular Dialight 70 Series towers, individual LED module connectors corrode or develop poor mating from repeated thermal expansion/contraction in steel mills and power plants. Internal cold-solder joints on the module PCB fail under vibration.
- ✓Hazardous zone tower loses ATEX/IECEx certification or shows moisture inside lens — Dialight HZ Series enclosures used in petrochemical plants experience gasket degradation after 3-5 years in hot, oily environments. Silicone gaskets harden and lose compression, allowing humid air and explosive vapors to ingress; condensation fogs the lens.
- ✓Control PCB relay or sequencer malfunction—no timing, continuous on, or erratic flashing — Dialight control boards in machine tool shops and automotive plants suffer from relay contact pitting (from switching inductive loads without suppression), electrolytic capacitor bulging (due to ambient heat near furnaces), and microcontroller firmware corruption from power spikes.

Frequently Asked Questions — DIALIGHT Repairs
Do you repair Dialight stack lights and signal towers across India?+
Yes. Synchronics Electronics repairs the complete Dialight product range—modular stack towers, sounder units, LED cartridges, hazardous zone enclosures, and control boards. We offer PAN India pickup from major cities including Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Pune, Ahmedabad, and Surat, with all repairs performed in our Vadodara, Gujarat facility. Turnaround is typically 5-7 business days for standard repairs.
What is the typical lead time for Dialight tower repair, and do you stock OEM components?+
Most Dialight repairs complete in 5-7 days. We stock common replacement items—LED cartridges (red, green, amber, blue), gasket kits, relay modules, and capacitors for Dialight control boards. For rare or obsolete modules, we source OEM or certified equivalent components and advise you on turnaround before commencing work. Emergency rush repairs (24-48 hours) available for critical production downtime situations.
Can Dialight ATEX and IECEx rated towers be recertified after repair?+
Synchronics can repair and pressure-test Dialight HZ Series hazardous zone towers to IP67 compliance, and we perform visual inspection per ATEX/IECEx standards. However, formal recertification documents require contact with your local notified body or Dialight distributors. We document all gasket replacement, torque specifications, and test results to support your certification renewals with regulatory authorities or insurers.
Why do Dialight LED modules fail so quickly in Indian textile and foundry plants?+
Dialight LED modules in high-temperature environments (foundries, furnace shops) experience accelerated solder fatigue and phosphor degradation. Additionally, textile mills and chemical plants expose towers to humidity and salt air, promoting corrosion inside module connectors. Dialight's plastic lens also yellows and becomes opaque under UV exposure and high heat, reducing light output. Synchronics replaces failed modules with high-brightness OEM or equivalent units and recommends protective covers or enclosure upgrades for extreme environments.
Do you offer preventive maintenance or inspection packages for Dialight signal towers?+
Yes. Synchronics offers on-site inspection and preventive maintenance for Dialight installations—cleaning internal contacts, checking gasket integrity, testing LED brightness and color, verifying sounder dB output, and identifying early corrosion or loose connections. For plants with many towers, we provide annual service contracts with scheduled pickups and return. Contact our sales team to discuss a customized maintenance plan for your facility.
How do I send my DIALIGHT unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DIALIGHT drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DIALIGHT repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DIALIGHT unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
