2100

Overload, remove load

Electrical · Alarm

Alarm 2100 is the default overload alarm using output current. One or both current transformers see an overload. The table says to check transfer-switch load-shed behavior: change the load, or use load shed.

Seen on: Air-cooled home standby generators with an Evolution 1.0 or 2.0 controller.

Likely causes

  • Connected load above the generator rating.
  • A load-shed module or transfer switch that did not drop managed loads.
  • A current transformer reporting an overload.

Checks an owner can do

  1. Switch off major loads (air conditioning, ranges, dryers, well pumps) and restart once.
  2. If the set has managed loads, confirm those appliances are the ones you expect to drop.

When to call a pro

If 2100 returns with only a light load, the current transformers, breaker, or load-shed wiring need a technician. Do not defeat load shed.
