LAURITZ KNUDSEN Equipment We Repair — By Category
LAURITZ KNUDSEN Product Lines We Repair
Our engineers are trained on the full LAURITZ KNUDSEN product range. Below are the major product families we service.
Process Controllers & PLC Modules
Lauritz Knudsen modular process control systems used in batch and continuous production. Common failures include input/output module degradation, communication port failures, and firmware corruption in legacy models affecting temperature, pressure, and flow control loops.
Instrumentation & Sensor Interface Cards
Signal conditioning and sensor interface modules for temperature, pressure, pH, and conductivity measurement. Typical faults include analog input card failures, thermocouple connector corrosion, and calibration drift in harsh food and pharmaceutical environments.
Valve Positioners & Actuator Controllers
Pneumatic and electro-pneumatic valve control equipment for process flow regulation. Failures stem from solenoid coil burnout, feedback potentiometer wear, supply air contamination, and control signal loss during rapid process changes.
HMI Panels & Operator Interfaces
Text-based and graphical display units for process monitoring and manual control. Common issues include LCD/LED screen failures, touchscreen responsiveness loss, internal relay/contactor failures, and communication protocol conflicts with legacy plant networks.
Power Supply & Distribution Modules
24 VDC and industrial power conditioning modules supporting Lauritz Knudsen control racks. Repair addresses capacitor failure, voltage regulation loss, backplane connector corrosion, and inadequate surge protection in Indian plants with unstable mains supply.

Common LAURITZ KNUDSEN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in LAURITZ KNUDSEN equipment arriving at our workshop.
- ✓Analog Input Card Signal Loss — Lauritz Knudsen analog input modules fail when exposed to moisture in food processing washdown areas or when thermocouple connectors corrode from salt spray in coastal Indian facilities. Cold-junction compensation circuits degrade, causing measurement errors exceeding 10% on critical temperature loops.
- ✓Process Controller CPU Freeze / Intermittent Halt — Lauritz Knudsen LK-500 and LK-3000 controllers experience watchdog timer resets when firmware becomes corrupted by power surges or when EEPROM wear causes checksum failures. Indian plants with weak electrical infrastructure and no UPS suffer frequent hangs during batch cycles.
- ✓Solenoid Valve Coil Burnout — Lauritz Knudsen pneumatic solenoid coils fail prematurely when continuous-duty solenoids are energised beyond rated cycle time in fast-loop process control. Moisture ingress into coil windings causes phase-to-ground insulation breakdown, drawing excessive hold current and tripping downstream fuses.
- ✓HMI Touchscreen Unresponsive / Dead Zones — Lauritz Knudsen HMI panels used in food plants develop touchscreen calibration drift when exposed to temperature cycling and frequent washdown. Electrostatic discharge during maintenance or CIP cleaning damages the capacitive touch controller, leaving portions of the display unresponsive.
- ✓24 VDC Power Supply Voltage Droop / Ripple — Lauritz Knudsen power supply modules degrade when Indian plant supply voltage fluctuates between 190-240 V or when loaded beyond rated capacity. Electrolytic capacitors dry out in tropical climates, reducing output voltage stability. Backplane connectors corrode, introducing contact resistance that compounds voltage drop.
- ✓Communication Port Failure / Protocol Timeout — Lauritz Knudsen controllers lose RS-485, Modbus, or proprietary serial communication when shielded cables are routed near high-current motor drives without proper ferrite shielding. Port ESD protection diodes degrade over time, and Indian industrial environments introduce conducted noise that causes CRC errors and timeouts in data exchange.
