Common ASCON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ASCON equipment arriving at our workshop.
- ✓ASCON sensor input error or out-of-range display — ASCON Pt100 or thermocouple sensor connection degradation due to vibration, oxidised connectors, or shielding loss in noisy Indian factory environments. Temperature reading fluctuates or shows error code E01/E02/E03.
- ✓ASCON relay contact stuck or pulsing erratically — Output relay coil arcing and mechanical wear after extended switching cycles. Contacts become oxidised or pitted, causing intermittent control and loss of heating or cooling function in pharmaceutical drying chambers or food freezing tunnels.
- ✓ASCON display segments missing or flickering — LCD segment driver failure due to electrolytic capacitor dry-out on the power board, or loose ribbon cable connection between display and main PCB. Common in high-humidity textile dyeing or food processing operations.
- ✓ASCON RS485 communication dropout or garbled data — ASCON controllers lose Modbus or proprietary protocol connectivity due to port corrosion, failed termination resistor, or damage to the isolation transformer. Industrial environments with welding or high-frequency switching create EMI-induced faults.
- ✓ASCON calibration offset or setpoint non-responsive — Loss of calibration parameters due to battery failure in the real-time clock (RTC), EEPROM corruption from power surges, or incorrect tuning parameters entered. Particularly common after grid outages or generator switchover failures in Indian industrial zones.
- ✓ASCON power supply failure or unstable output voltage — Input filter capacitors or voltage regulation circuits fail due to repeated power fluctuations, voltage spikes, or transformer inrush current from industrial machinery. ASCON controllers no longer boot or show intermittent reboots.

We offer PAN India pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nashik, Kolkata, and all other industrial cities. All repairs are handled at our 25000+ sq ft facility in Vadodara, Gujarat, with same-week turnaround for non-critical faults.
What is the typical turnaround time for ASCON temperature controller repair?+
Synchronics completes 70% of ASCON repairs within 5-7 working days. Complex issues like power supply redesign or firmware restoration may take 10-14 days. We provide daily status updates and expedite critical controls used in pharmaceutical batch production or food safety monitoring. Emergency weekend repairs are available for tier-1 clients.
Do you stock genuine ASCON spare parts?+
Yes. Synchronics maintains a dedicated inventory of ASCON relay modules, display segments, communication cards, and sensor connectors sourced directly from Italian distributors. We use only genuine or certified equivalent components for repairs to maintain equipment reliability and preserve your warranty. Emergency parts can be expedited from Europe if needed.
Can you repair ASCON Pt100 sensor connection issues?+
Absolutely. ASCON Pt100 and thermocouple input faults are among our most common repairs in Indian textile, pharmaceutical, and food facilities. Synchronics performs resistance testing, connector pin cleaning, shielding restoration, and input module recalibration using precision reference standards. We isolate EMI sources and recommend ferrite shielding for noisy factory floors.
Do you provide calibration certificates for repaired ASCON controllers?+
Yes. All ASCON temperature controllers and process instruments are calibrated against traceable reference standards and returned with ISO-compliant calibration certificates. This is essential for pharmaceutical GMP compliance, food safety audits, and automotive ISO TS16949 validation. Documentation includes pre-repair test data, repair actions, and post-repair verification results.
How do I send my ASCON 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 ASCON 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 ASCON 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 ASCON 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.
