Overview

An industrial generator is a diesel engine driving an alternator, sized and built to carry a real load for hours rather than to tide a house over. Ours are trailer-mounted AIRMAN SDG units, towable to site.

We rent eight sizes, from 13 kVA up to 440 kVA, the biggest we have. Site and site-office power, events and festivals, and businesses carrying on through an outage are the usual reasons.

Size it by what runs at the same time, not by the total of everything plugged in, and allow for the surge when a motor starts. “What this will run” further down this page works that out against the machines we rent.

Read the start-up and shut-down procedure on the controller before first use, and let the engine idle for a few minutes to cool before shutting it down after heavy load.

Troubleshooting

Won't start

Checks to try, in order

  1. Pull out the emergency stop button.
  2. Switch on the battery isolator.
  3. Check the fuel gauge — never let a diesel generator run dry.
  4. Use the preheat step before cranking, as shown on the controller.

Reference draft — always follow the manufacturer’s manual.

Engine running but no power out

Checks to try, in order

  1. Switch on the main output circuit breaker.
  2. Check the voltage selector is set correctly for the job.
  3. Check the cable connections at the output terminals or sockets.

Never change the voltage selector while the generator is running. Changes are made by trained staff only.

Reference draft — always follow the manufacturer’s manual.

Shuts down with an alarm

Checks to try, in order

  1. Read the alarm on the controller display (for example low oil pressure, high coolant temperature or low fuel) and note it.
  2. Check fuel, and check oil and coolant with the engine cold.

Call the workshop with the alarm code before restarting.

Reference draft — always follow the manufacturer’s manual.

Safety

  • Only a qualified electrician should connect a generator to a building or distribution board.
  • Earth the generator as required, and keep the canopy doors closed while it's running.

For diesel machine

  • Only trained, authorised operators should drive or operate this machine.
  • Walk around the machine before starting: leaks, damage, tyres or tracks, and people nearby.
  • Wear the seat belt, use three points of contact getting on and off, and use a spotter in tight areas.
  • Check for overhead power lines and underground services before digging or lifting.
