What this block does
Receives the assigned station charger's declared failure status.
A simple example
In a switchroom, the station battery can continue supplying protection and breaker controls during an AC supply interruption. The alarm system should distinguish charger loss from a low battery condition. For this reference, the drawing identifies “Charger fault contact” at the input and “Room charger alarm” at the output. Battery supply can remain present after charger failure.
What the drawings help you do
Start at the named input: Charger fault contact. Identify its source device or document and the state represented on the drawing. Follow the named output: Room charger alarm. Cross-reference its destination and separate the command from confirmation that the equipment responded.

What it represents
Receives the assigned station charger's declared failure status. A room DC interface connects station battery distribution, alarm contacts and operating circuits. DC supplies may remain energized when the room's normal AC supply is unavailable, so their source and distribution boundaries must be shown separately.
In a switchroom, the station battery can continue supplying protection and breaker controls during an AC supply interruption. The alarm system should distinguish charger loss from a low battery condition. For this reference, the drawing identifies “Charger fault contact” at the input and “Room charger alarm” at the output. Battery supply can remain present after charger failure.
Identify the DC source, returns and monitored branches. Do not infer battery autonomy, conductor polarity, isolation or earthing arrangements from a generic power block. 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: Charger fault contact. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Room charger alarm. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- Battery supply can remain present after charger failure.
- Identify the DC source, returns and monitored branches. Do not infer battery autonomy, conductor polarity, isolation or earthing arrangements from a generic power block.
Information to show or reference
- Label the source and connection reference for charger fault contact.
- Identify the destination and defined state of room charger alarm.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: Battery supply can remain present after charger failure.
A distinction that matters
Battery supply can remain present after charger failure. 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.
