COMELZ Product Lines We Repair
Our engineers are trained on the full COMELZ product range. Below are the major product families we service.
COMELZ Safety Relay Modules
Modular safety relay systems for emergency stop circuits, machine guarding logic, and critical process control. Common issues include relay contact degradation under load, control signal lag, and module connector corrosion in humid environments.
COMELZ Proximity Sensor Systems
Inductive and capacitive proximity sensors for machine positioning, part detection, and limit switching in automated assembly lines. Repairs address sensor face contamination, amplifier circuit failure, and cable interface issues common in dusty Indian manufacturing plants.
COMELZ Logic Control Units
Programmable logic modules and control cards for sequential machine operation, process automation, and real-time decision logic. Typical faults include CPU watchdog timeouts, program memory corruption, and I/O relay burnout.
COMELZ Timing and Counter Modules
Precision electronic timers, counters, and sequence controllers for cycle time management and production rate monitoring. Common repair work includes oscillator circuit failures, relay output sticking, and timing drift under temperature variation.
COMELZ Interface and Signal Conditioning
Signal isolation modules, voltage converters, and analog conditioning boards for safe integration of COMELZ systems with third-party equipment and legacy machinery. Repair focus includes transformer burnout, capacitor leakage, and voltage regulator failure.
COMELZ Emergency Stop and Interlock Systems
Hardwired emergency circuit controllers and safe state managers for compliance with Indian machinery safety standards. Repairs address dual-channel relay synchronization failures, circuit latching issues, and mechanical-electrical contact wear.

Common COMELZ Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COMELZ equipment arriving at our workshop.
- ✓Relay contact chatter and intermittent output — COMELZ relay modules experience contact wear and electromagnetic bounce under high-frequency switching (common in Indian spinning mills and packaging lines). Vibration and dust ingress accelerate contact surface oxidation.
- ✓Proximity sensor zero-point drift and false triggering — COMELZ inductive sensors degrade when exposed to ferrous metal dust (iron oxide in textile mills, steel fines in auto-component factories). Moisture and salt air in coastal Indian facilities corrode sensor faces, shifting detection distance.
- ✓Logic control unit CPU watchdog reset and program loss — COMELZ LCU modules suffer repeated watchdog resets due to RAM corruption from power surges (common with unreliable Indian grid supply), electrostatic discharge during humid monsoon, or battery-backed memory cell failure.
- ✓Safety relay synchronization loss and cross-channel lockup — Dual-channel COMELZ safety modules lose synchronization when one relay lags due to contact wear, mechanical stiction, or electromagnetic coil weakness. This triggers nuisance lockouts in critical machine stops.
- ✓Signal conditioning module output voltage regulation failure — COMELZ interface modules fail when input surge exceeds rated voltage (e.g., from unshielded motor cables or welding equipment nearby). Transformer saturation and voltage regulator IC failure result in erratic output across the signal range.
- ✓Emergency stop circuit latch failure and inability to reset — COMELZ emergency modules fail to latch when mechanical pushbutton contacts wear or when latching relay coil becomes weak. Reset circuits may fail due to capacitor leakage or thyristor gate circuit breakdown.
