Frequently asked
questions
My equipment stopped working urgently due to an unstable factory power supply. Am I eligible for free warranty, and what solution does EUTC offer for this emergency?
According to EUTC policy, damage caused by an unstable power supply is not covered under free warranty. However, EUTC provides paid repair services with our engineering team offering emergency support during business hours to restore equipment and provide a transparent diagnostic report.
Our machinery shut down due to a blown fuse on the control circuit board (or short-circuit caused by insect intrusion). Is this covered under warranty, and how long does EUTC take to resolve it?
Blown fuses due to overload, abnormal voltage, or external factors (such as insect intrusion) are generally not covered under free warranty. EUTC will conduct a diagnostic inspection within 24–48 business hours of receiving your support request. Following inspection, we will provide a repair quotation and return the equipment as quickly as possible. To prevent recurrence, you may also explore EUTC's Warranty and Maintenance service for scheduled periodic inspections.
We want to purchase third-party spare parts for replacement and self-install/retrofit on-site to control costs. How does EUTC handle warranty in this case?
Using non-genuine spare parts or performing self-installation/modifications without the supervision of EUTC technicians may void the active warranty policy. EUTC recommends contacting us prior to any component replacement or opting for EUTC's Retrofit & Upgrade service to modernize legacy lines and integrate new controllers and sensors safely and synchronously.
If I lose the original warranty certificate and the product warranty seal is faded or scratched, can I use the Purchase Invoice to claim warranty?
Unfortunately, this case is not eligible for free warranty even with a purchase invoice. Under EUTC's technical requirements, the product must remain intact with a valid warranty seal and matching serial number/barcode. If the seal or serial number is erased or altered, warranty coverage will be declined, and EUTC will advise on a paid repair service option.
My machinery is still under warranty, but I want to integrate new sensors to optimize performance. Can our internal technical team install them directly?
Please note that unauthorized modifications or installations without the guidance of EUTC specialists will void your free warranty coverage. A safer solution is to use EUTC's Retrofit & Upgrade service, where our engineers directly modernize the line and integrate new controllers and sensors to optimize performance. For detailed consultation, please contact EUTC via Hotline (+84) 28 3514 6818 or Mobile/Zalo 0908 572 749.
