ERL Equipment We Repair — By Category
ERL Product Lines We Repair
Our engineers are trained on the full ERL product range. Below are the major product families we service.
ERL Electromagnetic Control Relays (EC-Series)
Single and multi-contact electromagnetic relays for AC/DC industrial control. Common faults: coil burnout from voltage surges, contact wear causing intermittent switching, mechanical stiction in humid Indian mill environments.
ERL Thermal Overload Relays (TO-Series)
Bimetallic thermal relays for motor protection in three-phase and single-phase circuits. Repair focus: recalibration of thermal element, reset mechanism failure, contact deterioration affecting load disconnect.
ERL Time-Delay Relays (TD-Series)
Pneumatic and mechanical timer relays for sequencing, interlocking, and delay circuits. Common issues: air leak in pneumatic capsule, spring fatigue, contact chatter on low-load circuits.
ERL Solid-State Relay Modules (SSR-400 Series)
Hybrid electromagnetic-solid state relays for high-frequency switching and DC load control. Repair issues: triac failure, optical isolation damage, gate drive circuit malfunction.
ERL Latching Relays (LR-Series)
Bistable latching relays used in HVAC, irrigation control, and power distribution switchgear. Common faults: solenoid coil shorts, reluctance spring seizure, contact welding.
Why Choose Synchronics for ERL Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on ERL equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common ERL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ERL equipment arriving at our workshop.
- ✓Electromagnetic coil burnout and open winding — Voltage transients from motor contactor switching, inadequate surge suppression, or sustained overvoltage in Indian power networks. Common in textile mills and sugar plants where voltage fluctuations are severe.
- ✓Intermittent contact chatter and arcing — Oxide film buildup on silver-alloy contacts, mechanical bounce from worn armature pivots, or load transients. Prevalent in cement and steel plants with high ambient dust and vibration.
- ✓Thermal relay calibration drift and false trip — Bimetallic element aging, recalibration errors during previous servicing, or thermal hysteresis from ambient temperature swings in non-climate-controlled Indian factory floors.
- ✓Pneumatic timer relay response lag and air leaks — Rubber seals degraded by oil mist or condensation, mechanical wear in piston rod, or cracked silica gel desiccant capsule reducing air quality in textile dyeing and printing lines.
- ✓Solid-state relay triac short and load failure — Gate drive overstress from miswired trigger circuits, thermal runaway due to poor heatsink contact, or moisture ingress corroding gate oxide in high-humidity sugar mill or rice mill environments.
- ✓Latching relay reluctance spring jamming and weak hold — Corrosion of steel spring in high-moisture environments (irrigation systems, coastal power plants), mechanical misalignment after improper installation, or residual magnetism loss in armature.

Frequently Asked Questions — ERL Repairs
Do you repair ERL relays anywhere in India?+
Yes. Synchronics repairs the complete ERL relay range — control relays, thermal overload relays, time-delay relays, latching relays, and SSR modules. We offer PAN India courier pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all tier-2 cities. Single facility in Vadodara, Gujarat ensures quality control and consistent turnaround.
How do you handle ERL thermal relay recalibration in Indian manufacturing plants?+
ERL thermal relays often drift in calibration due to ambient temperature swings and mechanical stress in Indian factory environments. Synchronics uses precision load-test benches and calibrated furnaces to recertify your ERL TO-series relays to exact nameplate settings. We issue test reports showing trip current at 110%, 125%, and 150% of rated load — critical for insurance compliance in textile mills and power plants.
What is the average repair cost and time for ERL control relays?+
Most ERL electromagnetic relays (EC-Series, LR-Series) cost INR 2,500–8,000 to repair including parts and labor. Standard turnaround is 5–7 working days. Emergency express service (48 hours) available for critical plant stoppages. We quote after visual inspection and free fault diagnosis. Synchronics repair often costs 60–70% less than new relay replacement while maintaining original performance and warranty.
Can Synchronics supply NOS (new old stock) ERL relays if repair is not viable?+
Yes. Synchronics maintains inventory of obsolete and current ERL relay models through authorized partners. If coil or core damage is unrepairable, we source genuine replacement relays and install them pre-tested. Lead time typically 2–4 weeks for legacy ERL models like EC12-48DC or TO-63A used in older Indian textile and cement installations.
Do you provide on-site ERL relay repair and training at our facility?+
Yes. Synchronics offers on-site relay maintenance audits and technician training at sugar mills, power plants, and large textile mills. We teach relay failure diagnosis, proper coil testing, contact inspection, and preventive maintenance schedules. This reduces unplanned downtime and extends relay life in harsh Indian manufacturing environments. Contact our service team for custom on-site quotation.
How do I send my ERL 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 ERL 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 ERL 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 ERL 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.
