Dr. Thiedig Equipment We Repair — By Category
Dr. Thiedig Product Lines We Repair
Our engineers are trained on the full Dr. Thiedig product range. Below are the major product families we service.
TRS-DT Temperature Regulators
Digital temperature control units for extrusion, injection molding, and reactor heating. Common issues include sensor disconnection faults, PID tuning errors after power loss, and relay contact wear causing temperature overshoot.
PRC-DT Process Control Systems
Multi-zone process regulators for pharmaceutical batch heating and chemical reactor temperature management. Typical faults include analog input card failure, setpoint drift in memory, and communication timeouts between master and remote zones.
DCS-DT Distributed Control Modules
Networked thermal control nodes for large-scale process plants. Repair demands include Profibus/Modbus gateway failures, power supply dropout recovery, and zone synchronization errors across multi-chamber heating systems.
ERT-DT Emergency Response Thermostats
Safety-rated thermal overload protection units for high-temperature industrial ovens and reactors. Common failures: bimetal sensor fouling, mechanical switch jamming, and thermal runaway circuit failure needing reset.
HMI-DT Touchscreen Interfaces
Industrial operator panels for Dr. Thiedig system monitoring and manual override. Issues include display backlight failure, capacitive touch drift, and SD card corruption affecting recipe storage.

Common Dr. Thiedig Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in Dr. Thiedig equipment arriving at our workshop.
- ✓Temperature sensor signal loss or erratic reading — RTD (Pt100) or thermocouple sensor cable break, cold junction compensation circuit failure in the TRS-DT regulator, or sensor connector corrosion in high-humidity pharma environments. Thermal cycling and vibration in molding plants degrade solder joints at sensor terminals.
- ✓PID control loop oscillation or setpoint overshoot — Incorrect PID tuning parameters after power failure, integral gain saturation in the control algorithm, or delayed sensor feedback due to failed communication buffer. Common in Dr. Thiedig PRC-DT units controlling multi-zone batch reactors.
- ✓Relay contact welding or mechanical switch failure — Inductive load kickback causing arcing across heating element relay contacts in TRS-DT and ERT-DT models. Mechanical wear from 50,000+ switching cycles in continuous operation. Moisture ingress corroding silver alloy contacts in humid chemical plant environments.
- ✓Modbus or Profibus communication timeout between master and zone slaves — Corrupted firmware in DCS-DT gateway module, termination resistor failure on long cable runs (>100 m), or CRC checksum errors from electromagnetic interference near motor drives or welders in Indian manufacturing plants.
- ✓Power supply failure or brownout-induced system freeze — Faulty 24 VDC supply capacitors in older TRS-DT units (electrolytic aging), inadequate power conditioning during grid transients common in Indian industrial zones, or failed rectifier bridge in the 230/24 V converter module.
- ✓Setpoint value lost or reset to factory default after power cycle — EEPROM write-enable circuit failure in the TRS-DT or PRC-DT controller, corrupted nonvolatile memory from unexpected shutdown, or low backup battery voltage preventing parameter save on HMI-DT interface units.

Frequently Asked Questions — Dr. Thiedig Repairs
Do you repair Dr. Thiedig equipment anywhere in India?+
Yes. Synchronics has in-house expertise for the complete Dr. Thiedig product portfolio — temperature regulators, process control systems, distributed control modules, and HMI interfaces. We provide PAN India door pickup service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all major industrial cities. Full diagnostics, repair, and calibration are performed at our 20,000 sq ft facility in Vadodara, Gujarat, with 48-72 hour turnaround for most faults.
What is the most common fault in Dr. Thiedig TRS-DT temperature regulators?+
Sensor signal loss and PID oscillation are the two most frequent issues we encounter in TRS-DT units across Indian pharma plants. Sensor failures occur due to RTD cable fatigue in molding applications, while PID tuning drift happens after unplanned power loss. Synchronics performs sensor impedance testing, cold junction recalibration, and full loop retuning with live load validation on a heated calibration chamber. We return regulators with documented setpoint stability across ±0.5°C across the operating range.
Can Synchronics repair Dr. Thiedig DCS-DT Profibus communication failures?+
Absolutely. Profibus timeouts in multi-zone DCS-DT installations are often caused by termination impedance mismatch, corrupted gateway firmware, or electromagnetic interference from adjacent motor drives — all common in dense Indian manufacturing floors. We perform full network diagnostics using Profibus analyzers, reload gateway firmware, replace failed communication cards, and install shielded cabling with ferrite suppressors. We validate all zone slave nodes respond correctly before return.
Do you offer calibration certificates for repaired Dr. Thiedig equipment?+
Yes. All Dr. Thiedig temperature measurement circuits and sensor inputs are calibrated against NIST-traceable reference standards. We provide ISO 9001 traceable calibration certificates with each repair, essential for GMP compliance in pharma batch operations. Calibration data logged over the full operating range and included in the repair documentation.
What is your warranty on Dr. Thiedig controller repairs?+
Synchronics offers 12 months comprehensive warranty on all Dr. Thiedig repairs, covering parts and labor. We also provide 6 months on-site call-out support if critical failures recur. Most repairs qualify for our 'No Failure' guarantee — if the same fault recurs within warranty, we provide a replacement unit at no charge. Warranty extends across all of India.
How do I send my Dr. Thiedig 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 Dr. Thiedig 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 Dr. Thiedig 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 Dr. Thiedig 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.
