WEKO Equipment We Repair — By Category
WEKO Product Lines We Repair
Our engineers are trained on the full WEKO product range. Below are the major product families we service.
WEKO Process Control Modules
Compact PLC and RTU controllers for batch processing, mixing, and dosing applications. Common issues include memory corruption after power fluctuations, communication protocol faults on RS485/Ethernet interfaces, and sensor input card failures causing calibration drift.
WEKO HMI and Operator Panels
Industrial touchscreen and membrane-based human-machine interfaces for process visualization and remote control. Typical failures include display backlight degradation, capacitive touch layer delamination, and embedded Linux operating system crashes requiring firmware recovery.
WEKO Signal Conditioning & Isolation Modules
Precision analog and digital input/output converters for sensor and actuator interfaces in process automation. Repairs commonly address zero-span drift in 4-20mA circuits, galvanic isolation failures, and DIN-rail connector corrosion in high-humidity pharmaceutical and food plants.
WEKO Communication Interface Cards
Multi-protocol gateway modules supporting PROFIBUS, Modbus RTU/TCP, CANopen, and EtherCAT connectivity. Faults typically stem from clock crystal failures, surge-damaged RJ45 ports, and corrupted device configuration databases on flash memory.
WEKO Power Supply and Conditioning Units
Regulated 24VDC and 48VDC supplies with integrated UPS buffering for uninterrupted control system operation. Common repair cases involve capacitor bank failures, thermal shutdown circuit malfunctions, and secondary winding insulation breakdown under load transients.

Common WEKO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in WEKO equipment arriving at our workshop.
- ✓WEKO WPC Memory Card Corruption After Power Loss — WPC series controllers store ladder logic and runtime parameters on onboard flash memory. Sudden power cuts without UPS protection cause incomplete write cycles, corrupting the program and forcing the controller into safe-state lockout. Bacterial growth on battery-backed RAM contacts also degrades data retention.
- ✓WEKO HMI Display Backlight Failure and Color Shift — WOP series panels use CCFL or LED backlighting with aging electrolytic capacitors in the inverter circuit. After 3-5 years of continuous operation in Indian heat and humidity, capacitors dry out, causing voltage sag, dim display, and eventual complete backlight shutdown. Color shift indicates phosphor aging or PWM dimming circuit malfunction.
- ✓WEKO WCI Communication Card CRC and Frame Errors — Communication interface cards experience packet loss, frame overruns, and CRC mismatches due to electromagnetic interference (common in Indian textile mills and steelworks), corroded RJ45 connectors from humidity, or phase-locked loop (PLL) clock crystal degradation. PROFIBUS and Modbus RTU are most sensitive.
- ✓WEKO WSC Analog Module 4-20mA Zero and Span Drift — Signal conditioning modules in pharmaceutical and chemical plants experience calibration drift due to age-related precision resistor tolerance changes, thermistor junction degradation, and capacitive coupling from adjacent high-current power rails. Drift of >2% causes batches to fail in dosing and weighing applications.
- ✓WEKO WPS Power Supply Undervoltage and Hiccup Shutdown — WPS series supplies fail with intermittent hiccup shutdown (momentary loss of 24V output, then automatic restart) caused by aging bulk capacitors, thermal runaway in control transistors under sustained load, or feedback circuit oscillation. This is especially common after 7+ years in uncontrolled factory environments without ambient cooling.
- ✓WEKO WOP HMI Capacitive Touch Non-Response and Ghost Input — Touchscreen panels suffer capacitive layer separation from LCD glass due to thermal cycling and vibration in printing presses and injection molding machines. Moisture ingress under the touch overlay causes phantom touches and dead zones. Firmware crashes on embedded Linux also manifest as unresponsive interface.

Frequently Asked Questions — WEKO Repairs
Do you repair WEKO equipment anywhere in India?+
Yes, Synchronics repairs the complete WEKO product range — process controllers, HMI panels, signal conditioning modules, communication cards, and power supplies. We offer pan-India door-to-door pickup from all major cities (Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, Bangalore) and all shipments are routed to our central facility in Vadodara, Gujarat. Express repair service completes most WEKO jobs within 5-7 business days.
Can you repair WEKO WPC controllers if the program is lost or corrupted?+
Yes. Synchronics has specialized tools to dump WEKO WPC flash memory and analyze corrupted bytecode. If you have a backup of your ladder logic program (in AWL, STEP 7, or IEC 61131-3 format), we restore it directly. If no backup exists, we can often reconstruct the program logic from your process documentation or reverse-engineer it from memory snapshots. All recovered programs are tested on our simulation rig before re-installation in your hardware.
What is the typical turnaround time for WEKO HMI panel backlight and touchscreen repairs?+
WEKO WOP series HMI repairs — backlight replacement, touch panel recalibration, and firmware reflashing — typically complete in 3-5 working days at Synchronics. Simple backlight capacitor work turns around in 2 days. If the LCD glass itself is cracked, we source genuine WEKO replacement panels and extend turnaround to 6-7 days including customs clearance time. We provide loaner panels for critical applications.
Do you stock spare parts for WEKO equipment, or do we need to supply components?+
Synchronics maintains in-stock inventory of high-turnover WEKO components: electrolytic capacitors (all voltage/temperature ratings), precision resistor networks, crystal oscillators, RJ45 connectors, thermal pads, and firmware license dongles. For specialized modules (e.g. rare communication interface cards), we source parts through our authorized European distributors within 5-7 days. You are not required to supply parts; our repair quote includes all materials and labor. We also offer cost-down refurbished modules at 40-60% of new equipment cost.
How do I prevent WEKO control system failures in my Indian pharmaceutical or chemical plant?+
Synchronics recommends a preventive maintenance plan: (1) Replace electrolytic capacitors every 5-7 years as predictive measure; (2) Install 24VDC UPS supply (like WEKO WPS-UPS series) to protect against power fluctuations; (3) Perform annual firmware audits and security patching for WOP HMI and WCI communication cards; (4) Use surge-protected M23 connectors and shielded cables in high-EMI areas (textile mills, steelworks); (5) Store program backups in cloud or on external media. Contact our preventive maintenance team for a free site audit.
How do I send my WEKO 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 WEKO 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 WEKO 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 WEKO 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.
