Permits the defined automatic coordination when its required authority and health inputs are satisfied.

## In plain English

### What this block does

Permits the defined automatic coordination when its required authority and health inputs are satisfied.

### A simple example

In a microgrid serving a switchroom and industrial loads, the controller can move between grid-connected and islanded operating states only through its defined transition logic. Each state needs identifiable source roles and feedback. For this reference, the drawing identifies “Automatic authority and health” at the input and “Automatic control permission” at the output. Unavailable resources still require separate handling.

### What the drawings help you do

Start at the named input: Automatic authority and health. Identify its source device or document and the state represented on the drawing. Follow the named output: Automatic control permission. Cross-reference its destination and separate the command from confirmation that the equipment responded.

### Terms

- Input: Automatic authority and health
- Output: Automatic control permission
- Application reference: An explanation of a named drawing function or circuit relationship; the project documents define the equipment and its connections.

## What it represents

Permits the defined automatic coordination when its required authority and health inputs are satisfied. A microgrid operating-mode function coordinates how local sources and loads relate to the utility connection. The selected mode, the measured electrical condition and the actual switching configuration can differ during a transition.
In a microgrid serving a switchroom and industrial loads, the controller can move between grid-connected and islanded operating states only through its defined transition logic. Each state needs identifiable source roles and feedback. For this reference, the drawing identifies “Automatic authority and health” at the input and “Automatic control permission” at the output. Unavailable resources still require separate handling.
Show the requested mode, entry conditions, completion feedback and failure indication. These functional blocks explain control responsibilities and do not specify a ready-to-use operating sequence or grid-connection approval. The functional block is an independent explanation of this named application. Equipment-specific ratings, terminal connections and operating conditions must be established in the project documentation.

## How to read it

- Start at the named input: Automatic authority and health. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Automatic control permission. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- Unavailable resources still require separate handling.
- Show the requested mode, entry conditions, completion feedback and failure indication. These functional blocks explain control responsibilities and do not specify a ready-to-use operating sequence or grid-connection approval.

## Information to show or reference

- Label the source and connection reference for automatic authority and health.
- Identify the destination and defined state of automatic control permission.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: Unavailable resources still require separate handling.

## Important distinction

Unavailable resources still require separate handling. This reference describes the named application; it does not establish a new IEC graphical symbol, an ANSI device-function number or an exact manufacturer connection diagram.

## Facts
