IEEC Product Lines We Repair
Our engineers are trained on the full IEEC product range. Below are the major product families we service.
IEEC Soft Starters
Electronic soft starters for three-phase AC motors reducing inrush current and mechanical stress. Common issues include thyristor failures, control board faults, and phase loss detection errors causing nuisance trips and motor stalling during startup cycles.
IEEC Motor Starter Assemblies
Traditional electromechanical and solid-state motor starters rated 7.5 kW to 1000+ kW. Failures typically involve contactor chatter, overload relay drift, and power section corrosion in high-humidity industrial environments common in Indian manufacturing plants.
IEEC Power Distribution Controllers
Programmable control modules for multi-motor distribution and load sequencing in textile, cement, and steel industries. Repair focuses on microprocessor failures, relay module failures, and communication bus timeouts on legacy serial interfaces.
IEEC VFD Interface Cards
Legacy communication and control cards for integrating IEEC starters with variable frequency drives and SCADA systems. Common faults include isolated DC supply collapse, encoder signal loss, and firmware corruption affecting plant floor automation protocols.
IEEC Overload Relay Units
Thermal and electronic overload protection modules protecting motors from sustained overcurrent conditions. Typical failures: bimetallic strip calibration drift, electronic threshold circuit malfunction, and contact oxidation preventing trip signal transmission.

Common IEEC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in IEEC equipment arriving at our workshop.
- ✓Thyristor gate drive circuit failure in soft starters — IEEC soft starters use isolated gate drivers for firing thyristor pairs. Optocoupler degradation, coupling capacitor ESR increase, or microcontroller reset pin oscillation causes loss of gate pulse amplitude, preventing thyristor commutation and creating sustained conduction states.
- ✓Phase loss detection false alarms triggering unnecessary motor stops — IEEC starters monitor phase voltage asymmetry using voltage divider networks and window comparators. Corroded transformer secondary windings, PCB trace hairline cracks, and zener diode junction leakage cause erratic phase angle measurement, triggering nuisance trips.
- ✓Contactor chatter and welded contacts in motor starters — IEEC contactors experience mechanical bounce during coil energisation, especially under voltage sag conditions common in Indian power systems. Arc erosion from repeated inrush currents and atmospheric corrosion in salt-air coastal plants cause contact surface degradation and adhesive bonding.
- ✓Microprocessor watchdog timeout errors causing repeated power cycling — IEEC PDC modules use 8-bit or 16-bit microcontrollers with internal watchdog timers. Flash memory corruption from power surges, clock oscillator capacitor leakage, and stack overflow from firmware defects cause processor reset looping, particularly after grid frequency disturbances.
- ✓Isolation barrier failure in opto-coupled interface modules causing crosstalk — IEEC interface cards use optocouplers rated for 3750 V isolation between field devices and CPU logic. Extended thermal stress, moisture ingress during monsoon season, and high dV/dt transients from motor soft-start applications degrade internal LED-photodiode junction reliability.
- ✓Bimetallic overload relay calibration drift causing nuisance motor protection — IEEC thermal overload relays rely on precise bimetallic strip curvature and contact arm tension. Repeated thermal cycling, corrosion of spring materials, and mechanical vibration in cement mills and sugar plants cause progressive calibration drift, reducing pickup current accuracy by 5-15%.

Frequently Asked Questions — IEEC Repairs
Do you repair IEEC equipment anywhere in India?+
Yes. Synchronics repairs the full IEEC product range — soft starters, motor control centres, distribution controllers, and legacy interface modules across all Indian industrial regions. We offer door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other metros. All repairs are performed in our factory in Vadodara, Gujarat, with turnaround times typically 7-10 working days for routine faults.
What is the typical turnaround time for IEEC soft starter repair?+
IEEC soft starters usually require 7-10 days for diagnostic testing, component replacement, and factory verification testing. Emergency rush repairs are available for critical production lines — we prioritise diagnostic work on the same day and aim for 48-72 hour turnaround. Synchronics maintains stock of common IEEC replacement modules including gate drive boards, power thyristors, and control transformers to minimise delay.
Can Synchronics repair IEEC equipment with missing firmware or corrupted memory?+
Yes. Synchronics has archived IEEC firmware images for PDC controllers and legacy interface modules dating back to 1995. We perform ROM re-flashing using secure in-circuit programming techniques and validate all configuration registers post-repair. For obsolete IEEC models where original firmware is unavailable, we reverse-engineer control logic and develop compatible firmware incorporating your plant's motor protection and sequencing requirements.
Do you offer IEEC equipment preventive maintenance contracts?+
Yes. Synchronics offers quarterly preventive maintenance programmes for IEEC motor starters and soft starters covering thermal imaging inspection, contact resistance measurement, thyristor curve tracing, and phase angle verification. We document all readings against baseline signatures and alert you to degrading components before failure occurs, protecting against unplanned downtime in critical production lines like cement kiln drives and sugar plant crusher motors.
What warranty do you provide on IEEC repairs?+
Synchronics provides 12-month parts and labour warranty on all IEEC repairs, covering defects in workmanship and component quality. Emergency warranty claims are handled within 48 hours with onsite replacement units provided for critical applications. Extended 24-month warranties are available for PDC modules and soft starters used in hazardous areas or marine environments where corrosion risk is elevated.
How do I send my IEEC 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 IEEC 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 IEEC 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 IEEC 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.
