Lookup label: SBCG
Drawing use: Schematic
Reference families: Manufacturer

Representation: Functional block
Installation focus: substations
Input: Battery monitor data
Output: Station battery condition information

Connects the installed battery monitoring system's declared values and alarms to station supervision.

## In plain English

### What this block does

Connects the installed battery monitoring system's declared values and alarms to station supervision.

### 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 monitor data” at the input and “Station battery condition information” at the output. Monitoring data does not replace capacity assessment.

### What the drawings help you do

Start at the named input: Battery monitor data. Identify its source device or document and the state represented on the drawing. Follow the named output: Station battery condition information. Cross-reference its destination and separate the command from confirmation that the equipment responded.

### Terms

- Input: Battery monitor data
- Output: Station battery condition information
- Application reference: An explanation of a named drawing function or circuit relationship; the project documents define the equipment and its connections.

## What it represents

Connects the installed battery monitoring system's declared values and alarms to station supervision. 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 monitor data” at the input and “Station battery condition information” at the output. Monitoring data does not replace capacity assessment.
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 monitor data. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Station battery condition information. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- Monitoring data does not replace capacity assessment.
- 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 monitor data.
- Identify the destination and defined state of station battery condition information.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: Monitoring data does not replace capacity assessment.

## Important distinction

Monitoring data does not replace capacity assessment. 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
