LAUER Equipment We Repair — By Category
LAUER Product Lines We Repair
Our engineers are trained on the full LAUER product range. Below are the major product families we service.
Paxdisk HMI Terminals
LAUER Paxdisk operator interface terminals for real-time process visualization and manual control. Common faults include touchscreen unresponsiveness, firmware corruption, communication losses on Ethernet/Profibus, and backlight LED degradation in industrial environments.
Tasteratur Operator Panels
Heavy-duty LAUER membrane keypad and pushbutton control panels for harsh factory floors. Typical failures include membrane keypad short circuits, LED indicator burnout, encoder drift, and sealed enclosure moisture ingress in high-humidity or washdown environments.
Paxline Distributed Control Modules
Modular LAUER distributed I/O and control nodes for decentralized automation. Repair challenges include terminal block corrosion, relay chatter, signal isolation failures, and fieldbus interface degradation in noisy electrical environments.
Compactline Legacy Controllers
Older LAUER programmable logic and sequence control units still operating in established Indian manufacturing plants. Common defects include capacitor aging, EEPROM data loss, power supply regulation drift, and communication port interface failures.
LAUER Communication Gateways
Protocol converters and fieldbus interfaces for integrating LAUER systems with Profibus, Profinet, and CANopen networks. Typical faults include gateway firmware hangs, serial port intermittency, Ethernet PHY failures, and protocol timeout errors under high data load.
LAUER Power Supply Units
Regulated 24V DC and 230V AC power conditioning modules for LAUER control systems. Repair issues include capacitor dry-out, transformer winding insulation breakdown, rectifier diode failure, and voltage regulation IC degradation in thermal cycling conditions.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common LAUER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in LAUER equipment arriving at our workshop.
- ✓Paxdisk touchscreen dead zones and erratic input — Capacitive touch controller IC failure or digitizer cable dry-joint. Often triggered by thermal shock, vibration loosening internal connections, or electrostatic discharge from operator contact in dry factory floors.
- ✓LAUER operator panel membrane keypad shorts and dead keys — Elastomer conductive layer degradation, moisture ingress under seal, or manufacturing defect in membrane stack adhesion causing layer separation. Particularly common in food processing plants with high humidity and washdown cycles.
- ✓Paxline I/O module relay chatter and contact welding — Excessive switching current, inadequate EMI suppression, or relay coil voltage sagging under high-load conditions. In Indian textile mills and automotive plants, poor power supply regulation and close proximity to high-current equipment exacerbates this issue.
- ✓LAUER fieldbus communication timeouts and protocol errors — Profibus/Profinet interface IC failure, cable shield rupture, or corrupted gateway firmware causing frame retransmissions. High electromagnetic noise in Indian steel plants and heavy machinery manufacturing environments can trigger latent IC failures.
- ✓Compactline controller EEPROM data corruption and program loss — Thermal cycling aging of EEPROM retention capacitors, power supply glitches during program upload, or electrostatic discharge. Legacy LAUER Compactline units from the 2000s are particularly vulnerable as capacitor lifespan approaches 20+ years.
- ✓LAUER power supply 24V regulation drift and brownout conditions — Electrolytic capacitor dry-out in the primary filter stage, transformer winding insulation breakdown under sustained thermal load, or feedback network component aging. Ambient temperatures exceeding 45°C in Indian manufacturing plants accelerate this degradation.

Frequently Asked Questions — LAUER Repairs
Do you repair LAUER equipment anywhere in India?+
Yes. Synchronics repairs the full LAUER product range — Paxdisk HMI terminals, Tasteratur operator panels, Paxline distributed I/O modules, Compactline controllers, communication gateways, and power supplies. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other cities. Same facility in Vadodara, Gujarat. Typical turnaround is 5-7 working days for most repairs.
Can you recover lost programs from LAUER Compactline controllers?+
Yes. If your Compactline unit has retained its EEPROM data, we can extract the application program using specialized LAUER engineering tools and provide you with documented logic listings. In cases where EEPROM is corrupted, we can help you reload from your backup source code. Synchronics maintains LAUER documentation and OEM software licenses for this purpose.
What is the typical repair cost for a LAUER Paxdisk HMI terminal?+
LAUER Paxdisk repair cost depends on the fault — touchscreen controller replacement runs INR 8,000-15,000; Ethernet interface board replacement INR 6,000-10,000; firmware recovery INR 3,000-5,000. We provide detailed quotation after free diagnostic testing. Most repairs are more economical than replacement, especially for 5-7 inch models still under active use in Indian plants.
Do LAUER Paxline I/O modules need recalibration after repair?+
For input modules (analog), yes — Synchronics recalibrates 4-20mA and 0-10V channels against certified reference standards. Relay output modules require functional verification on test bench with load simulation. We provide calibration certificates for plants with ISO or quality audit requirements. Typically INR 1,500-2,500 per module.
Can Synchronics repair LAUER gateway modules with Profibus or Profinet?+
Yes. Our engineers are trained on LAUER Paxline gateway configuration and protocol implementation. We repair communication interface boards, reload gateway firmware, and test with actual Profibus/Profinet analyzers. If your network is down, contact us immediately — we keep spare gateway modules for emergency swap-outs while we repair your unit.
How do I send my LAUER 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 LAUER 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 LAUER 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 LAUER 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.
