DSE PLC Product Lines We Repair
Our engineers are trained on the full DSE PLC product range. Below are the major product families we service.
DSE 6110 / 6120 Series
Entry-level generator controllers for single genset autonomy and engine protection. Repair of digital display faults, CAN interface failures, and fuel supply command circuit breakdowns common in harsh industrial environments.
DSE 7110 / 7120 Series
Mid-range intelligent genset controllers with mains failure sensing, automatic start/stop logic, and dual-generator load-sharing. Common repairs include mains contactor relay failures, engine crank signal interpretation faults, and battery charger circuit burnout.
DSE 8610 / 8620 Series
Advanced multi-generator synchronisation controllers with droop load-sharing, AMF (Automatic Mains Failure) logic, and industrial networking. Repair focus: genset load balance failures, frequency regulation faults, and CAN-bus communication timeouts.
DSE 9110 / 9120 Series
Flagship networked controller platform with IP connectivity, SCADA integration, and predictive diagnostics. Repairs include Ethernet interface failures, SD card firmware corruption, sensor input linearization faults, and real-time clock (RTC) battery depletion.
DSE Automatic Transfer Switch (ATS) Modules
Standalone ATS controllers for three-phase and single-phase mains-to-genset switchover. Common faults: voltage sensing circuit drift, contactor coil burnout, bypass breaker activation delays, and phase sequence detection errors in Indian grid-unstable regions.
DSE Synchronising Modules
Dedicated multi-genset synchronisation units for parallel operation and load-sharing in industrial power stations. Repair issues: phase angle stability drift, frequency ramp rate faults, reactive load distribution errors, and genset isolation relay chatter.

Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common DSE PLC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DSE PLC equipment arriving at our workshop.
- ✓DSE controller no display or LCD blank screen — Backlight LED failure, contrast potentiometer drift, or internal 5V regulator burnout from supply spikes common in Indian industrial environments with poor power conditioning.
- ✓Genset fails to auto-start or delayed engine cranking — Battery charger circuit output low, starter solenoid relay contact oxidation, or CAN-bus crank signal lost due to loose connectors or corrosion at engine ECU interface — common after monsoon or in coastal installations.
- ✓Mains sensing failure - genset starts incorrectly on grid power — Voltage divider resistor drift in the mains sense circuit, comparator IC failure, or opto-isolator degradation — causes false mains detection especially in regions with voltage fluctuations between 150V-280V AC.
- ✓Frequency regulation unstable or genset oscillates under load — Governor sensor input signal noise, PID loop tuning drift, or fuel control feedback potentiometer wear in the electronic governor interface — causes hunting and synchronisation errors in load-sharing applications.
- ✓CAN-bus communication timeout or genset isolation in multi-unit setup — CAN termination resistor open circuit, loose/corroded DB9 connector, or CAN transceiver IC failure — breaks synchronisation between master and slave controllers in parallel genset installations common in Indian industrial parks.
- ✓Battery charger output low or no charge current — Transformer winding short, bridge rectifier diode failure, or series voltage regulator IC burnout from sustained overcharge — prevents DSE controller operation and genset auto-start capability.
