HEART power.supply-lost H-02001

Main power lost. Main power is gone. Running on battery or backup, if any.

Likely causes

• A power cut in the building or the area.
• A tripped breaker or blown fuse on the product's supply.
• A loose or unplugged power cable or charger.
• A failed power adapter or internal power supply.

How to fix or prevent it

1. Check whether other equipment nearby also lost power.
2. Check the breaker, fuse, plug and cable.
3. If it runs on a battery or UPS now, note how long that lasts, and save work or stop safely before it runs out.
4. Replace a failed adapter with one of the right rating.
5. To prevent it: give important equipment a UPS or backup battery, and test it.

What the HEART does by itself

If it has a battery, UPS or a supercapacitor, it sends this alert while it still can, and tells a person. It may reduce its own load to last longer. It resolves the alert by itself when main power returns. With no backup at all, its watcher sees system.flatline instead.

When to call service

If power does not return after checking breakers and fuses, or a breaker trips again at once.

Inside a message a code is written bare, "code": "storage.full". In logs, tickets, documents and searches it is written HEART storage.full. Things that simply happen, such as system.started, are event types, not faults. The codes are defined in Part 3, Section 5.4, and their H-numbers in Section 5.7. All of it, as data: fault-codes.json.
