Identifies the selected method for monitoring the continuity of the assigned battery connection.

## In plain English

### What this block does

Identifies the selected method for monitoring the continuity of the assigned battery connection.

### A simple example

In a substation control building, the battery can support breaker trip circuits while the charger AC supply is unavailable. Supervision must identify whether the charger, battery or a downstream feeder is affected. For this reference, the drawing identifies “Battery connection supervision” at the input and “Battery-path health indication” at the output. The monitoring method must be documented.

### What the drawings help you do

Start at the named input: Battery connection supervision. Identify its source device or document and the state represented on the drawing. Follow the named output: Battery-path health indication. Cross-reference its destination and separate the command from confirmation that the equipment responded.

### Terms

- Input: Battery connection supervision
- Output: Battery-path health indication
- Application reference: An explanation of a named drawing function or circuit relationship; the project documents define the equipment and its connections.

## What it represents

Identifies the selected method for monitoring the continuity of the assigned battery connection. A station battery system supplies protection, control and other assigned DC loads through a documented charger and distribution arrangement. Charger output, battery contribution and load distribution are related but separately monitored paths.
In a substation control building, the battery can support breaker trip circuits while the charger AC supply is unavailable. Supervision must identify whether the charger, battery or a downstream feeder is affected. For this reference, the drawing identifies “Battery connection supervision” at the input and “Battery-path health indication” at the output. The monitoring method must be documented.
Identify every source, protective device, isolation boundary and return. Battery capacity, DC fault duty, charging settings and ventilation require the selected battery-system design; illustrative circuits do not establish autonomy. 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: Battery connection supervision. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Battery-path health indication. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- The monitoring method must be documented.
- Identify every source, protective device, isolation boundary and return. Battery capacity, DC fault duty, charging settings and ventilation require the selected battery-system design; illustrative circuits do not establish autonomy.

## Information to show or reference

- Label the source and connection reference for battery connection supervision.
- Identify the destination and defined state of battery-path health indication.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: The monitoring method must be documented.

## Important distinction

The monitoring method must be documented. 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
