CANDOR Product Lines We Repair
Our engineers are trained on the full CANDOR product range. Below are the major product families we service.
Candor PLC Controllers
Modular programmable logic controllers for process automation and batch control in pharmaceutical and chemical manufacturing. Common failures include corrupted firmware, communication port failures, and relay output card malfunctions requiring EPROM reprogramming.
Candor HMI Touch Panels
Industrial touchscreen terminals for real-time process monitoring and operator interface in manufacturing plants. Typical issues include screen backlight failure, resistive touch layer degradation, and serial communication bus failures between HMI and PLC.
Candor Data Acquisition Systems
Multi-channel analog-to-digital conversion and sensor interface modules for temperature, pressure, and flow measurement in process plants. Common faults include ADC chip degradation, signal conditioning amplifier failure, and isolated input channel dropout.
Candor Process Instrumentation
Temperature controllers, pressure transmitters, and process signal conditioning modules for industrial monitoring and control loops. Repair challenges include thermocouple junction failure, 4-20mA signal loop breakage, and cold junction compensation drift.
Candor Communication Modules
Industrial Ethernet gateways, Modbus converters, and fieldbus interfaces for connecting legacy automation equipment to modern SCADA networks. Failures stem from lightning surge damage, protocol stack corruption, and connector oxidation.
Candor Power Supply Units
Regulated DC power supplies and redundant power management modules for continuous plant operation and backup power in critical automation systems. Common failures include capacitor electrolyte leakage, transformer insulation breakdown, and regulator circuit failure.

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 CANDOR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CANDOR equipment arriving at our workshop.
- ✓Candor PLC firmware corruption and boot failure — Power loss during program download or EEPROM write cycle, resulting in corrupted bootloader code. Candor controllers use proprietary firmware format stored in flash memory vulnerable to incomplete write cycles.
- ✓HMI touchscreen unresponsive or erratic pointer — Resistive touch overlay degradation from thermal cycling and humidity ingress in Indian climate, combined with calibration drift. Candor HMI panels use 4-wire resistive screens that degrade faster in high-humidity pharmaceutical environments.
- ✓PLC communication port failure - Modbus/RS485 timeout — RS485 transceiver IC degradation from ESD events, or damaged DE/RE control line logic causing half-duplex contention. Candor CP-series use single-chip RS485 transceivers without TVS diode protection in some revisions.
- ✓Analog input channel stuck or reading offset error — ADC conversion circuit aging in DAS modules, drift in precision signal conditioning amplifiers, or damaged isolation optocoupler on isolated input channels. High ambient temperatures in Indian mills accelerate capacitor aging.
- ✓Temperature controller display blank or erratic reading — LCD segment driver chip failure or cold solder joint on display connector in Candor TC-100 models. High vibration environments in textile and sugar mills cause mechanical stress on display flex connectors.
- ✓Ethernet gateway protocol stack crash or IP unreachable — Corrupted network firmware on Candor GW-ETH modules due to interrupted firmware update or DHCP server timeout causing infinite loop. Default IP address conflict in shared subnets is also common in multi-site Indian plants.

Frequently Asked Questions — CANDOR Repairs
Do you repair Candor equipment anywhere in India?+
Yes. Synchronics repairs the complete Candor automation product range - PLCs, HMI panels, data acquisition systems, and process instrumentation modules. We offer PAN India door pickup service from major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Surat, and Jaipur. All repairs are performed at our ISO 9001 certified facility in Vadodara, Gujarat. Typical turnaround is 5-7 business days.
What is the typical repair cost for Candor CP-48 PLC controller failure?+
Candor CP-48 repair costs range from Rs 8,000-25,000 depending on the fault. Firmware corruption and input card failures (Rs 8,000-12,000) are lower cost than transformer or power supply board replacements (Rs 18,000-25,000). Synchronics provides free diagnostic assessment and written quotation before any repair work begins. We also offer competitive exchange options with refurbished CP-48 units at Rs 35,000-45,000.
Can Candor PLC programs be recovered if the controller won't boot?+
Yes. Synchronics specializes in firmware recovery from Candor controllers using EEPROM chip-off techniques and proprietary data extraction tools. If the program memory is intact but bootloader is corrupted, we can rebuild the boot sector and restore operation. Success rate is 85-90% for recoverable firmware. We provide recovered source code on USB and documented program listings. Non-recoverable code requires client reprogramming or use of backup versions if available.
Do you service Candor equipment under warranty and after-warranty contracts?+
Yes. Synchronics offers comprehensive AMC (Annual Maintenance Contract) and call-out repair services for Candor installations across Indian pharmaceutical, chemical, and food processing facilities. We provide 24-hour emergency breakdown support, preventive maintenance schedules (quarterly/bi-annual), spare parts inventory management, and on-site technician support for critical plant outages. Contact us for customized support packages.
What documentation do I need to provide for Candor device repair?+
For fastest repair turnaround, provide the original equipment manual, PLC program backup (if available), recent fault logs or error codes displayed on HMI, and detailed description of symptoms observed. For Candor controllers without documentation, Synchronics maintains a library of standard firmware versions and can assist in program reconstruction. Ship units with original packaging if possible. Include your contact details and authorization on the packing slip.
How do I send my CANDOR 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 CANDOR 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 CANDOR 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 CANDOR 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.
