CHEROKEE Product Lines We Repair
Our engineers are trained on the full CHEROKEE product range. Below are the major product families we service.
Cherokee Programmable Logic Controllers (PLCs)
Compact and modular PLCs for process automation and machine control. Common failures include input/output card degradation, power supply failures, and firmware corruption affecting relay logic and real-time I/O scanning.
Cherokee Analog and Digital I/O Modules
Discrete and analog input/output cards for sensor integration and actuator control. Typical issues include channel isolation faults, ADC calibration drift, and connector oxidation causing signal loss.
Cherokee Communication Interfaces
Ethernet, serial, and fieldbus gateway modules for inter-device communication. Failures often involve firmware version incompatibility, PHY layer errors, and handshake timeout conditions.
Cherokee Power Supply Modules
Regulated 24V DC and auxiliary power units for PLC racks and distributed I/O. Common faults include capacitor degradation, transformer core saturation, and voltage regulation circuit failures.
Cherokee Battery-Backed Real-Time Clock Modules
Real-time clock and data retention cards with lithium or NiMH battery backup. Failures stem from battery depletion, crystal oscillator drift, and memory latch-up during power transients.

Common CHEROKEE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CHEROKEE equipment arriving at our workshop.
- ✓Cherokee PLC input card channel lockout — Extended operating temperatures or input surge transients can damage the optical isolation circuitry on Cherokee digital input modules, causing one or more channels to stop responding to sensor signals. This is especially common in older CP-2000 and CP-3000 racks exposed to unfiltered electrical noise.
- ✓Cherokee PLC firmware boot failure with LED error code — Corruption of the PLC's internal firmware flash memory can occur due to unexpected power loss, improper shutdown during programming, or ESD damage during field maintenance. This typically triggers amber or red LED status indicators and prevents normal startup sequencing.
- ✓Cherokee analog output module voltage drift and nonlinearity — Age-related capacitor aging, reference voltage source degradation, or op-amp offset errors in Cherokee AO cards cause output signals to drift beyond +/- 2% accuracy. This is especially problematic in process control loops where 4-20 mA setpoints must be precise.
- ✓Cherokee communication module timeout and no Ethernet heartbeat — RJ-45 connector corrosion, PHY transceiver IC failure, or incompatible firmware revisions between Cherokee gateway modules and connected SCADA systems cause network communication to drop intermittently or completely. Indian humid industrial environments accelerate connector oxidation.
- ✓Cherokee power supply +24V rail oscillation and voltage sag — Bulk electrolytic capacitor ESR increase, transformer secondary winding shorts, or failure of the PWM feedback regulator circuit in Cherokee PS-24/10 and PS-24/20 units cause the 24V rail to oscillate or sag under load. This can reset connected I/O modules unpredictably.
- ✓Cherokee real-time clock module battery exhaustion and date reset — Lithium coin cells in Cherokee RTC modules have a 10-15 year lifespan and gradually lose capacity. When battery voltage drops below the data retention threshold, the module loses the current date/time and reverts to a default date, disrupting batch-stamping and timestamped event logs.

Frequently Asked Questions — CHEROKEE Repairs
Do you repair Cherokee PLC equipment anywhere in India?+
Yes. Synchronics repairs the full Cherokee product range including all PLC models, I/O modules, power supplies, communication interfaces, and real-time clock cards. We offer PAN-India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Kolkata, and all other major industrial cities. All repairs are performed at our ISO-certified facility in Vadodara, Gujarat.
What is the typical repair turnaround time for Cherokee PLC input/output module failures?+
Standard turnaround is 5-7 working days for most Cherokee I/O module repairs, including channel isolation testing, component replacement, and functional validation. Express service (3-4 days) is available for critical production stops. Complex firmware restore jobs may require 7-10 days. We provide daily status updates and expedited return shipping via courier.
Can Synchronics restore corrupted Cherokee PLC firmware from a complete dead unit?+
Yes. Synchronics uses advanced in-circuit programmers and Cherokee development tools to recover firmware in most failure scenarios. If you have a backed-up copy of your application code, we can reload it directly. Otherwise, we work with you to reconstruct the logic or provide factory default firmware. We maintain a library of Cherokee firmware versions from 1990 onwards.
How do I prevent Cherokee power supply failures in my Indian textile mill?+
Install quality 24V surge protectors and uninterruptible power supplies (UPS) to filter voltage transients common in Indian grid infrastructure. Synchronics recommends replacing electrolytic capacitors in Cherokee PS units proactively every 7-10 years of continuous operation. We also suggest keeping spare input/output modules on hand and scheduling preventive thermal imaging inspections annually.
What should I do if my Cherokee PLC shows an amber LED error code during startup?+
An amber LED typically indicates firmware corruption or PLC memory initialization failure. First, verify your main 24V power supply is stable (use a multimeter). If voltage is good, contact Synchronics with your PLC model number and LED pattern — we can often diagnose the fault remotely. Most amber LED issues are resolved by firmware reload or EEPROM replacement, typically completed within one week.
How do I send my CHEROKEE 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 CHEROKEE 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 CHEROKEE 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 CHEROKEE 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.
