EVCO Product Lines We Repair
Our engineers are trained on the full EVCO product range. Below are the major product families we service.
EVK Series — Universal Inputs Temperature Controller
Compact DIN rail-mounted controllers handling multiple sensor types (Pt100, NTC, thermocouple). Common failures include sensor input signal loss, relay output sticking, and display segment corruption. Synchronics restores input calibration, replaces relay modules, and repairs LCD driver circuits.
EVD Series — Digital Display Thermostats
Panel-mounted controllers with integrated display and dual setpoint logic for cooling/heating applications. Frequent issues include frozen display, unstable temperature readout, relay chatter, and lost calibration data. Synchronics rebuilds display modules, recalibrates sensor circuits, and restores EEPROM parameters.
EVH Series — Advanced Process Controller
High-performance industrial controller with analog outputs, network connectivity (Modbus, CAN), and programmable logic. Repairs include analog output card failure, communication protocol errors, program memory corruption, and PID tuning parameter loss.
EV3 Series — Compact Smart Controller
Microprocessor-based units with Ethernet connectivity for food, pharmaceutical, and refrigeration plants. Common faults: network port failure, SD card read errors, password lock-out, and real-time clock drift. Synchronics resolves communication issues, recovers data, and resets controller logic.
TP Series — Touchscreen Display and Logger
Human-machine interface modules with alarm management, trend recording, and alarm list export. Typical failures: capacitive touch unresponsiveness, data logger corruption, USB communication dropout, and parameter sync loss between controller and display.
Sensor Modules — Humidity, Pressure, Multi-Input Cards
Auxiliary input modules for extended sensor capability in cold storage and environmental monitoring. Failures include connector corrosion, signal amplifier burnout, and floating null offset errors requiring recalibration against certified standards.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common EVCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EVCO equipment arriving at our workshop.
- ✓EVK display frozen or partial segment dropout — LCD driver IC failure, cold solder joint on display connector, or CMOS RAM data corruption. Moisture ingress in harsh refrigeration environments accelerates LCD driver degradation.
- ✓Sensor input shows error or wildly fluctuating reading — Loose Pt100 probe connection, degraded sensor interface amplifier, or incorrect input channel configuration in EEPROM. EVCO units read -19 or 99 error codes when analog input stage fails.
- ✓Relay output stuck ON or chattering — Relay coil burnout, welded relay contacts, or faulty output driver transistor. High-inrush loads in compressor circuits commonly cause relay failure in EVD series units.
- ✓Lost calibration or setpoint parameters after power failure — Corrupted EEPROM or low backup battery voltage (typical in EVK/EVD units after 5+ years). Firmware update interruption can also cause parameter loss.
- ✓Modbus or Ethernet communication failure on EVH series — RJ45 port solder joint fracture, RS485 transceiver IC failure, or corrupted communication firmware. Electrical noise in industrial environments degrades communication ICs.
- ✓TP touchscreen unresponsive or capacitive touch intermittent — Degraded capacitive touch controller IC, display flex cable micro-fracture, or firmware glitch in touch calibration. Humidity in cold rooms can degrade touch IC performance.

Frequently Asked Questions — EVCO Repairs
Do you repair EVCO equipment anywhere in India?+
Yes. Synchronics repairs the full EVCO product range — EVK, EVD, EVH, EV3 controllers, TP touchscreen displays, sensor modules, and all EVCO data loggers. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and 100+ other Indian cities. Repairs happen at our state-of-the-art facility in Vadodara, Gujarat. Most repairs completed within 24-48 hours.
Can you repair EVCO controllers that lost their stored parameters and calibration data?+
Yes. EVCO units store calibration setpoints, PID tuning constants, and sensor offset values in EEPROM memory. When backup battery fails or power surges corrupt memory, Synchronics can recover or reprogram this data if you provide original equipment documentation. We also hold factory calibration templates for EVK, EVD, and EVH series. If your data is lost, we reprogram with industry-standard defaults and advise on backup battery replacement to prevent future loss.
What is the typical cost and turnaround time for EVCO controller repair?+
Most EVCO repairs (sensor calibration, relay replacement, display repair, firmware restoration) range from INR 3,500 to 12,000 depending on fault complexity. Turnaround is typically 24-48 hours from receipt. Major board-level component failures may extend to 5 working days. Synchronics provides advance diagnostics report with cost quote before commencing work. Emergency same-day repair available for critical food safety and pharmaceutical applications.
Do you replace EVCO display and touchscreen modules with genuine OEM parts?+
Yes. Synchronics sources genuine EVCO LCD displays, TP touchscreen modules, and relay cards directly from authorized EVCO distributors in India. We do not use clone or third-party display modules. All replacement components are tested for 72 hours before dispatch. For obsolete EVCO models, we identify compatible display upgrades and manage firmware integration to ensure seamless operation with your existing controller.
How do I send my EVCO equipment for repair and what documentation do I need?+
Contact Synchronics via phone (0265-2396888), email (service@synchronics.co.in), or WhatsApp with your EVCO model number and fault description. We arrange door pickup from your facility. Please include original controller documentation, commissioning report, or recent maintenance records if available. Send photos of error codes or faulty display. We provide repair tracking reference and dispatch your repaired equipment with test report and warranty document within agreed timeline.
How do I send my EVCO 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 EVCO 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 EVCO 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 EVCO 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.
