HOLLINGSWORTH Product Lines We Repair
Our engineers are trained on the full HOLLINGSWORTH product range. Below are the major product families we service.
Hollingsworth Motion Controllers
Precision stepper and servo drive controllers for multi-axis automation. Common faults include encoder signal loss, phase winding shorts, and PWM driver IC failures affecting motion synchronization and accuracy in packaging and assembly lines.
Hollingsworth Proportional Valve Drivers
Closed-loop proportional solenoid drivers for hydraulic and pneumatic control. Repair focuses on current sensing circuit faults, MOSFET burnout, and feedback linearization module failures common in material handling and press automation.
Hollingsworth Legacy PLC Modules
Modular programmable logic controllers and I/O cards for industrial process control. Frequent issues include input optocoupler degradation, output relay contact stiction, and program memory bit rot in equipment running 15+ years.
Hollingsworth Encoder Modules
Incremental and absolute rotary encoder signal conditioners with quadrature output. Common faults: shielding corrosion leading to signal noise, XOR gate IC failures, and capacitor plague affecting signal differentiation circuits.
Hollingsworth Fieldbus Gateways
Industrial Ethernet, Profibus, and CANopen interface boards for legacy Hollingsworth equipment integration. Repair addresses galvanic isolation failures, transformer coil opens, and PHY IC faults preventing network synchronization.
Hollingsworth Sensor Interface Boards
Analog conditioning and multiplexing boards for pressure, temperature, and displacement transducers in production lines. Typical failures: instrumentation amplifier offset drift, relay contact degradation, and isolation diode leakage.

Common HOLLINGSWORTH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HOLLINGSWORTH equipment arriving at our workshop.
- ✓Hollingsworth encoder signal dropout on startup — Quadrature decoder IC (typically 74LS85 or 74HC85 logic) loses synchronization during power sequencing, or shielded cable capacitive coupling causes false edge detection. Common in HC-2000 and HC-3000 controllers in humid Indian manufacturing plants.
- ✓Proportional valve driver output deadband offset error — Hollingsworth PVD series relies on precision resistor networks for feedback linearization. Thermal drift and humidity ingress cause 1-5% output offset, degrading proportional flow control accuracy in hydraulic press and injection molding applications.
- ✓HL-CPU-2 program memory bit corruption — intermittent logic errors — Hollingsworth legacy PLCs use EEPROM or older EPROM technology susceptible to charge leakage and cosmic ray bit flips after 10+ years. Also caused by repeated power cycle stress and inadequate capacitor filtering during brownouts.
- ✓Hollingsworth proportional valve spool stiction causing slow response — PVD driver IC fails (internal MOSFET short or open), reducing solenoid current ramp rate. Alternatively, electromagnetic transient spikes damage the dv/dt clamp circuit, preventing proper valve actuation within the 50-200ms response window specified by Hollingsworth.
- ✓FGW Ethernet gateway communication timeout — Modbus TCP errors — Hollingsworth Ethernet transformers suffer primary winding opens due to surge transients on plant floor 24VDC buses, or the PHY IC (Realtek RTL8019 or similar) loses clock synchronization. Galvanic isolation capacitors also degrade, breaking packet transmission.
- ✓Sensor interface board ADC reference drift — analog measurement error creep — Hollingsworth SIB boards use precision voltage references (REF02, LM4041) that drift 0.5-1% per year in high-humidity Indian factory environments. PCB trace corrosion and solder joint micro-cracks also degrade the reference power supply filtering.

Frequently Asked Questions — HOLLINGSWORTH Repairs
Do you repair Hollingsworth equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete Hollingsworth product portfolio — motion controllers, proportional valve drivers, legacy PLCs, encoder modules, fieldbus gateways, and sensor interface boards. We operate across India with PAN-India courier pickup from Mumbai, Pune, Delhi, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and tier-2 industrial cities. All repairs are performed in our Vadodara, Gujarat facility by 180+ certified engineers.
My Hollingsworth HC-3000 controller shows intermittent motion jerking. What could be wrong?+
Intermittent jerking on Hollingsworth motion controllers typically stems from encoder signal noise (dirty quadrature signals), microstepping lookup table corruption, or phase current sensing circuit offset drift. Synchronics performs scope analysis of the encoder signal quality, tests the motor phase currents under load, and validates the microcontroller's velocity loop response. We repair or replace the signal conditioning stages and recalibrate the current feedback network to restore smooth operation.
What is the typical turnaround time for Hollingsworth PLC module repair?+
For Hollingsworth HL-CPU and I/O modules, Synchronics provides 7-10 working day turnaround including component replacement, full functional testing, and recalibration. Express repair (3-5 days) is available for mission-critical equipment affecting production. We provide loaner modules where possible to minimize your downtime, and offer emergency on-site support for critical failures in Gujarat and nearby states.
Do you have Hollingsworth spare parts in stock or do you source them?+
Synchronics stocks high-demand Hollingsworth IC components (microcontrollers, gate drivers, operational amplifiers) and passive components (capacitors, resistors, optocouplers). For scarce legacy Hollingsworth modules, we locate parts through our industrial electronics supply network across India and USA. We also perform component-level repair — replacing failed ICs and repairing PCB damage — which is faster and more cost-effective than full module replacement in many cases.
My facility uses Hollingsworth fieldbus gateways. Can you upgrade them to modern protocols?+
Yes. Synchronics can retrofit Hollingsworth FGW gateways by replacing the core PHY and microcontroller stages to support modern protocols like Ethernet IP or MQTT while preserving your existing Hollingsworth control logic. We also provide firmware updates to latest Hollingsworth driver releases, add ESD protection enhancements, and implement redundancy features for critical automation lines. Custom protocol bridges are available for legacy equipment integration.
How do I send my HOLLINGSWORTH 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 HOLLINGSWORTH 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 HOLLINGSWORTH 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 HOLLINGSWORTH 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.
