Service scope

Electrical and controls expertise for generator reliability

We repair generator control circuits and replace obsolete or failed controllers, then configure, test and recommission the generator around the site’s operating requirements.

Our specialist scope: generator electrical systems, controls, protection, wiring, switchgear interfaces, communications and SCADA. Where a fault is mechanical, fuel-system or engine-internal, we can identify the control-system evidence and coordinate the electrical interface with the appropriate mechanical specialist.

What we can do

  • Controller power, input and output testing
  • Alarm, shutdown and permissive logic review
  • Controller replacement and panel modifications
  • Parameter configuration and protection settings
  • Functional testing with ATS, switchboard, PLC or SCADA systems

What you receive

  • Restored automatic and manual operating modes
  • Documented controller settings where practical
  • Verified alarms, trips and status signals
  • A migration path where the original controller is obsolete

Useful information for your enquiry

  • Generator make, model and rating
  • Controller, AVR or protection make and model
  • Fault codes, alarm history or operating symptoms
  • Photos of the generator, control panel and switchboard
  • Site location, access constraints and operational priority
