Onsite generator repairs, servicing & maintenance across Gauteng
Rivonia
Rivonia generator work is weighted toward offices, commercial properties and apartment standby sets. ProService Generator Repairs diagnoses controller, transfer and no-start faults on site, and services the set while the supply is still on.

Rivonia and Edenburg sit between Morningside, Sunninghill and Woodmead. The generators are often in a plant room serving an office floor, a retail site or a residential complex.
A set that runs while the floors stay dark has not transferred. That is a controller or ATS fault until the measurements say otherwise. A set that never tries to start is a different path: battery, alarm or a missing auto-start signal.
Preventative servicing is the practical booking for offices that cannot discover a flat battery during a meeting. Oil, filters and a charge-system check are done before the supply drops. No building is named here. The visit is for the address you give.
Control, transfer and planned servicing lead the Rivonia work.
AMF, ATS and alarm faults that stop a transfer.
Scheduled visits for office and complex sets.
Oil, filters, coolant and a start-circuit test.
Voltage that will not hold once office loads connect.
No-start checks before a working day is lost.
Fuel and battery faults on commercial diesels.
Broader fault finding when the panel is not the whole story.
A controlled load test where a no-load run is not enough.
Rivonia faults are usually about a commercial set that should have been ready.
A latched shutdown stops an auto-start. The code is read before the panel is replaced.
The engine can be healthy while the building never leaves the utility.
Battery, starter and the start signal are separated before parts are listed.
Output that sags under office load is measured at the AVR and alternator.
Frequency falls when engine speed falls. That is fuel, governor or load, not an AVR setting to twist.
Filters and a flat charger show up together on sets that only run in outages.
A Rivonia no-start is often found when the supply has already dropped. The set may never have been called to start, it may be held off by an alarm, or the battery may only click. Fuel is checked if the engine turns and will not fire.
The controller, the battery and the fuel each get a test that matches the symptom.
Office loads show a weak AVR as soon as equipment connects. Low voltage with steady speed points at the regulator, alternator, wiring or a breaker. Low frequency means the engine is slowing.
Transfer and auto-start faults are the Rivonia emphasis. Manual start is compared with automatic start so a key-start is not treated as a working changeover.
Basement tanks that sit still load the filters. Air in the lines and a weak lift pump are checked when the engine dies under load. Injectors follow only if delivery is still poor.
Offices, complexes and smaller commercial standby installations.
Standby sets serving office floors.
Shared apartment and mixed-use backup.

They serviced our Rivonia office generator over the weekend to ensure our staff weren't disturbed. They quickly sorted out a highly complex control panel fault.
