ERHARDT & LEIMER Equipment We Repair — By Category
ERHARDT & LEIMER Product Lines We Repair
Our engineers are trained on the full ERHARDT & LEIMER product range. Below are the major product families we service.
EL EPC Edge Guide Controllers
Electronic edge position controllers for web guiding on converting and printing lines. Common faults include sensor drift, feedback loop instability, and analog input circuit failures causing guide hunting or web misalignment.
EL Tension Control Systems
Load cell-based and dancer roll tension controllers for roll-to-roll production. Typical issues include load cell calibration drift, PID loop oscillation, and hydraulic proportional valve interface problems affecting web tension stability.
EL Laser Registration Systems
Optical laser sensor units for print mark detection and registration correction on packaging and label printing equipment. Faults include laser diode degradation, photodiode sensitivity loss, and alignment drift after mechanical vibration.
EL Micro Control Units
Compact logic controllers for converter and printing machinery automation. Repair issues involve firmware corruption, relay contact welding, analog-to-digital converter failures, and communication port degradation.
EL Web Inspection Modules
Machine vision-based defect detection systems for film, paper, and fabric production. Common failures include camera sensor degradation, lighting LED failure, software license corruption, and USB interface issues.
EL Proportional Valve Driver Cards
Electronic driver boards for proportional solenoid valve control in tension and guiding systems. Typical faults include MOSFET burnout, current feedback circuit failure, and spool position transducer signal loss.

Common ERHARDT & LEIMER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ERHARDT & LEIMER equipment arriving at our workshop.
- ✓Edge guide hunting and oscillation — EL EPC sensor feedback exhibits hysteresis or the proportional valve response time is delayed. This causes the guide to overshoot and hunt across web edges, especially on high-speed converting lines running thin substrates.
- ✓Tension controller drift and instability — Load cells in Erhardt & Leimer tension systems develop zero offset drift due to repeated thermal cycling and fatigue. Amplifier circuits also degrade, reducing signal-to-noise ratio and causing PID loop instability on fast webs.
- ✓Laser registration mark detection failure — Extended laser diode operation and thermal stress reduce optical output. Photodiode spectral response shifts or develops surface contamination.
- ✓Proportional valve response lag and dither — EL proportional valve driver cards suffer MOSFET or current feedback amplifier failures. Solenoid coil insulation breakdown and spool friction increase valve deadband and slow response, degrading guiding and tension control precision.
- ✓Microcontroller firmware corruption or lockup — EL MCU-series logic controllers experience firmware corruption from power surges or flash memory wear. Watchdog timer failures allow firmware to hang, preventing operator input and halting production.
- ✓Web inspection camera and lighting degradation — Machine vision components in Erhardt & Leimer WIM modules suffer LED aging and CCD/CMOS sensor dark current buildup. Software license expiration or corruption prevents system startup on modern Erhardt & Leimer web inspection platforms.

Frequently Asked Questions — ERHARDT & LEIMER Repairs
Do you repair Erhardt & Leimer equipment anywhere in India?+
Yes. Synchronics repairs the complete Erhardt & Leimer product range — edge guides, tension controllers, laser registration systems, web inspection modules, and control electronics. We offer same-day freight pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all other Indian cities. Repairs are performed in our Vadodara facility with fast turnaround — typical 5-7 working days.
What is the typical turnaround time for Erhardt & Leimer edge guide repair?+
Standard repair turnaround for EL EPC edge controllers and sensor units is 5-7 working days including full calibration and bench testing. Urgent jobs can be prioritized for 2-3 day turnaround at express rates. Synchronics maintains spare proportional valve driver cards and sensor modules to minimize downtime for customers.
Can Synchronics repair Erhardt & Leimer tension load cells and PLC modules?+
Yes, absolutely. Synchronics specializes in Erhardt & Leimer load cell re-calibration, amplifier circuit repair, and MCU logic controller firmware restoration. We have certified load cell calibration rigs and can issue traceability certificates. For microcontroller faults, we perform diagnostic testing, firmware backup, reprogramming, and full functional validation.
Do you stock Erhardt & Leimer spare parts and consumables?+
Synchronics maintains an inventory of common Erhardt & Leimer replacement components including proportional valve driver PCBs, edge position sensors, laser diode modules, and photodiode assemblies. We also source OEM parts through authorized Erhardt & Leimer distribution channels. Lead times are typically 2-4 weeks for special order items.
What should I do if my Erhardt & Leimer web guide is hunting and causing register errors?+
First, verify that edge sensors are clean and properly aligned. Check for proportional valve response lag using an oscilloscope if available. Contact Synchronics immediately — we can diagnose sensor drift, valve hysteresis, and PID tuning issues remotely or via pickup. In most cases, sensor cleaning and valve calibration resolve hunting within 1-2 days.
How do I send my ERHARDT & LEIMER 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 ERHARDT & LEIMER 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 ERHARDT & LEIMER 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 ERHARDT & LEIMER 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.
