JANICH & KLASS Equipment We Repair — By Category
JANICH & KLASS Product Lines We Repair
Our engineers are trained on the full JANICH & KLASS product range. Below are the major product families we service.
JK Series Servo Drives
Precision AC servo drives for motion control in textile looms, packaging machines, and printing equipment. Common faults include phase loss, encoder signal loss, thermal shutdown, and capacitor degradation in the power module.
JK Automation Controllers
Industrial control modules for sequential automation, process logic, and machine synchronization. Repair focus includes relay module failures, input/output card burnout, and firmware corruption in older analog-based systems.
JK Electromechanical Actuators
Heavy-duty rotary and linear actuators for chemical dosing, valve automation, and production line positioning. Common issues include solenoid coil failure, mechanical wear in gearboxes, and electrical connector corrosion in humid plant environments.
JK Encoder and Feedback Modules
Incremental and absolute position encoders supplying real-time feedback to motion systems. Typical failures include bearing wear causing signal dropout, connector degradation, and cable shielding breakdown in electromagnetic noise environments.
JK Power Supply Units
Regulated DC and multi-output industrial power supplies for control cabinet integration. Common faults: capacitor swelling, transformer secondary winding short, thermal overload relay trips, and rectifier bridge diode failure.

Common JANICH & KLASS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in JANICH & KLASS equipment arriving at our workshop.
- ✓Servo drive phase loss and shutdown — Janich & Klass servo drives require balanced three-phase input. Indian plant power quality issues — load shedding, transformer tap changes, and loose MCB contacts — cause single-phase detection fault. The drive automatically cuts output to protect motor winding.
- ✓Encoder signal loss and position error — Janich & Klass servo systems use high-frequency encoder signals (4kHz typical). Long control cable runs, poor shielding, or proximity to VFDs and welding equipment in Indian manufacturing plants cause signal degradation and checksum errors on the feedback line.
- ✓Thermal shutdown and intermittent operation — Janich & Klass power modules use dated thermal design for 1950s-1980s manufacturing standards. In high ambient Indian plant environments (45-50C), cooling fins accumulate dust and lint. Electrolytic capacitors age faster in heat, reducing ripple filtering and raising internal dissipation.
- ✓Relay module welding and stuck contacts — Janich & Klass automation controllers use traditional electromechanical relay arrays for logic output. Inductive motor loads, voltage spikes from loosely terminated cables, and arcing across relay contacts cause metal buildup and electrical welding of the contact pair.
- ✓Connector corrosion and intermittent faults — In humid Indian coastal and chemical plant environments, brass connectors on Janich & Klass modules oxidize and develop green patina. Contamination builds contact resistance, causing voltage drop and random signal dropouts during production runs.
- ✓Firmware corruption and controller lockup — Older Janich & Klass controllers store logic programs in battery-backed RAM. Power surges, weak backup battery (depleted after 10-15 years), or sudden power cuts cause memory loss and corrupted state tables. The controller enters safe mode or becomes unresponsive.

Frequently Asked Questions — JANICH & KLASS Repairs
Do you repair Janich & Klass equipment anywhere in India?+
Yes. Synchronics repairs the complete Janich & Klass product range — servo drives, automation controllers, electromechanical actuators, encoders, and power supplies. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities, with same-facility repair and testing in our Vadodara, Gujarat headquarters.
What is the typical repair turnaround time for Janich & Klass servo drives?+
Standard turnaround is 5-7 working days for diagnostic, component replacement, and load testing. For critical production stoppages, Synchronics offers emergency 24-48 hour express service with priority bench allocation. We maintain stock of common replacement modules such as power transistor pairs, capacitor kits, and relay assemblies specific to Janich & Klass drive architecture to minimize parts sourcing delays.
Do you have original Janich & Klass spare parts in stock?+
Synchronics sources genuine and cross-compatible components from authorized German and Indian stockists. For obsolete parts no longer manufactured, we engage specialized electronics component recovery companies and identify modern equivalents with identical electrical specifications. All replacement capacitors, diodes, and relays are verified for functional and dimensional fit before installation.
Can you repair Janich & Klass equipment that was installed 20-30 years ago?+
Yes. Janich & Klass equipment from the 1980s and 1990s remains repairable because the company maintained consistent connector standards and modular architecture. Our engineers reverse-engineer schematics from field units, have access to German technical bulletins through industrial archives, and routinely restore vintage controllers and servo drives used in established Indian textile mills and processing plants.
What warranty does Synchronics offer on Janich & Klass repairs?+
All repaired Janich & Klass equipment carries a 12-month parts and labour warranty covering manufacturing defects. Optional extended 24-month warranty is available for critical production equipment. Synchronics conducts 72-hour burn-in testing and issues detailed test certificates showing performance metrics, ensuring confidence before return to your production line.
How do I send my JANICH & KLASS 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 JANICH & KLASS 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 JANICH & KLASS 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 JANICH & KLASS 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.
