Generator services

Generator changeover and ATS support for connected sites

From its Centurion base, EMPS reviews generator changeover and ATS enquiries for Gauteng homes, commercial properties and industrial facilities. Selected KZN project requests are assessed around the installed control arrangement, distribution equipment, safe switching and the travel scope required.

Understand the existing changeover arrangement

An enquiry should establish whether the site uses a manual changeover, automatic transfer switch or another control arrangement, and which circuits are transferred. Existing drawings, controller information, photographs and the reported sequence help identify where the failure may sit.

Check sensing, interlocking and control signals

Automatic operation can depend on mains sensing, generator start signals, warm-up and transfer delays, return-to-mains logic, electrical or mechanical interlocking and feedback contacts. The suitability of each point is checked against the generator and existing installation rather than assumed from the word ATS.

Protect people and equipment during testing

Changeover testing can affect live circuits and essential loads. A responsible site contact, safe isolation procedure, clear switching plan and awareness of critical equipment are needed before any manual or automatic sequence is tested.

Scope upgrades only after assessment

If the existing ATS, changeover, controller or cabling is unsuitable, EMPS can explain the required corrective or upgrade scope. Compatibility, ratings, enclosure space, protection and available components must be confirmed before a particular solution is promised.

What to expect

Details to share about an ATS or changeover fault

Every site and generator is different. The final scope is confirmed after we understand the equipment, access conditions and work required.

  • Manual or automatic changeover arrangement and controller details
  • Which circuits or distribution boards should transfer
  • What happens during a mains failure and when mains returns
  • Generator make, model, capacity and start behaviour
  • Photographs of the ATS, changeover and relevant distribution boards
  • Any recent electrical work, alarms, nuisance trips or failed tests
Project photographs

Project photographs

Photographs for this service will be added when suitable EMPS project images are available.

Service questions

Frequently asked questions

Can EMPS investigate an ATS that is not starting the generator?

Yes, an automatic-start complaint can be assessed across the ATS sensing and control signals, generator controller, wiring and related equipment. The exact cause must be established before a replacement ATS or controller is recommended.

Can an ATS be added to any generator?

Not universally. Generator controls, ATS ratings, sensing, transfer arrangement, protection and the existing distribution system must be compatible. EMPS assesses the complete arrangement before confirming whether an automatic changeover scope is suitable.

Will testing the changeover interrupt the building?

It can, depending on the arrangement and test sequence. The test must be planned with the site operator around critical loads, safe switching and any required alternative power; no uninterrupted outcome should be assumed without reviewing the installation.
