A non-resettable counter records events without a normal user reset function.

## What it represents

A non-resettable counter records events without a normal user reset function. It is used where the total event history is part of the documented equipment indication.

## How to read it

- Check the specified retention behaviour when the auxiliary supply is lost.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

## Information to show or reference

- Define qualifying event
- State counter supply
- Reference retention and rollover

## Important distinction

A totalising counter is different from a preset counter intended to be reset each operating cycle.
