CROUZET Product Lines We Repair
Our engineers are trained on the full CROUZET product range. Below are the major product families we service.
Electromechanical Relays (RM, RXM, RXG Series)
General-purpose control relays with 2-16 contact configurations for circuit protection and switching logic. Common repair: contact pitting, coil insulation breakdown, armature stiction, and hum noise in energised state. These relays often fail due to high inrush currents or moisture ingress in humid mill environments.
Solid-State Relays (86 Series, 84 Series)
Semiconductor-based switching for AC and DC loads without moving contacts. Prone to IGBT gate drive failures, thermal drift in control circuits, and triac failure under surge transients. Crouzet SSRs are popular in textile looms and packaging lines where switching frequency exceeds 100 cycles/minute.
Time-Delay Modules (CROUZET ANA Series, DIN-Rail)
Electronic timers offering delay-on-make, delay-on-break, and repeat-cycle functions. Faults include capacitor leakage affecting timing accuracy (±10% drift), relay coil aging, and potentiometer contact wear. Used extensively in Indian sugar mills for load sequencing and motor soft-start control.
Logic Relay Controllers (Logireg Series, Millenium)
Modular logic controllers combining relay switching with timer and counter functions. Repair focus: worn terminal blocks, corroded PCB traces, electrolytic capacitor failure, and relay contact degradation. Common in Indian pharmaceutical and chemical batch processes requiring hardened logic control.
Surge Protection & Transient Suppressors
Varistor and MOV-based modules protecting relay coils and control circuits from voltage spikes. Failures occur from repeated surge events in poorly earthed Indian plant sites. Synchronics replaces varistors, checks downstream relay coil integrity, and verifies protection circuit function.

Common CROUZET Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CROUZET equipment arriving at our workshop.
- ✓Contact pitting and stiction in RM relay contacts — High switching currents, inductive kick-back from motor loads, and moisture ingress in humid textile mill environments cause progressive contact erosion and mechanical friction, making relays stick in energised state.
- ✓Coil insulation failure and megohm drift in RXM relays — Extended operation in high-temperature plant areas (>50C continuous), salt-air environments near coastal Indian facilities, and moisture-laden air in sugar refineries accelerate insulation paper breakdown in relay coils.
- ✓SSR IGBT gate drive circuit failure and load short-circuit — Transient voltage spikes from unshielded control wiring, inadequate heat-sink cooling, and switching into partially short-circuited AC loads cause avalanche breakdown of gate-drive transistors or the main power IGBT in Crouzet 86 Series SSRs.
- ✓Timing error and capacitor leakage in ANA timer modules — Electrolytic capacitors in the integrator circuit degrade over 5-8 years of continuous operation in warm, dusty sugar mill and chemical plant environments, causing timing drift of 15-30% and erratic cycle skips.
- ✓Relay contact welding in solid-state relay control modules — Induction motor inrush currents exceeding relay rating, missing surge suppression on coil terminals, or stalled load conditions cause persistent coil current, overheating the control relay output and welding contact surfaces in Crouzet 84 Series units.
- ✓Terminal block corrosion and loose connections on DIN-rail modules — Vibration from adjacent machinery, thermal cycling, and corrosive fumes (NH3, SO2) in Indian processing plants cause screw terminals to loosen and copper contacts to oxidise, increasing contact resistance and intermittent open-circuit faults.

Frequently Asked Questions — CROUZET Repairs
Do you repair Crouzet equipment anywhere in India?+
Yes. Synchronics repairs the full Crouzet product range — electromechanical relays, solid-state relays, time-delay modules, logic controllers, and surge protection devices. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, and 100+ other cities. All repairs are centralised in our Vadodara, Gujarat facility where we maintain Crouzet test benches and genuine spare inventory.
What is the typical repair turnaround time for Crouzet RM and RXM relays?+
Standard repairs (contact cleaning, coil testing, reseating) are completed in 2-3 working days. Complex repairs involving coil rewinding take 5-7 days. We prioritise urgent repairs for spinning mills and refineries — express turnaround can be arranged within 24 hours if parts are in stock. Synchronics ships repaired units via courier with tracking and a 12-month warranty.
My Crouzet 86 Series SSR shows intermittent load switching. What could be wrong?+
Intermittent SSR failures in Indian plants typically stem from: (1) transient voltage spikes on control wiring — add shielded cables and varistor protection; (2) faulty gate-drive capacitors — we replace electrolytic capacitors older than 5 years; (3) loose terminal connections from vibration — we re-torque and apply dielectric grease; (4) partial IGBT degradation under high load duty. Synchronics will hi-pot test the device, measure IGBT gate voltage and leakage current, and replace the control PCB if necessary. Testing takes 1 day.
Can Synchronics rewind Crouzet relay coils or must I replace the entire relay?+
We rewind Crouzet relay coils for RM, RXM, and RXG series if the coil former and frame are in good condition. Rewinding uses original Crouzet specifications — wire gauge, turn count, insulation class — and costs 30-40% less than a new relay. However, if the relay has been internally arced or the former is cracked, replacement is more cost-effective. We advise on the best option after inspection.
What warranty do you provide on repaired Crouzet equipment?+
All Crouzet repairs carry a 12-month parts and labour warranty from the date of handover. If a repaired unit fails within this period due to defective workmanship or materials (not due to customer misuse or surge events), we will repair or replace it free of charge. We also offer extended 24-month warranties on complex repairs like coil rewinds or SSR module replacements for a small additional fee.
How do I send my CROUZET 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 CROUZET 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 CROUZET 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 CROUZET 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.
