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

Representation: Functional block
Installation focus: switchrooms
Input: Sump pump run contact
Output: Pump running indication

Carries the assigned drainage pump's operating feedback to room supervision.

## In plain English

### What this block does

Carries the assigned drainage pump's operating feedback to room supervision.

### A simple example

In a switchroom, water ingress, temperature, humidity and equipment-service alarms can be sent to the station controller with separate point names so an operator can identify the affected area. For this reference, the drawing identifies “Sump pump run contact” at the input and “Pump running indication” at the output. Running feedback does not prove successful drainage.

### What the drawings help you do

Start at the named input: Sump pump run contact. Identify its source device or document and the state represented on the drawing. Follow the named output: Pump running indication. Cross-reference its destination and separate the command from confirmation that the equipment responded.

### Terms

- Input: Sump pump run contact
- Output: Pump running 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

Carries the assigned drainage pump's operating feedback to room supervision. Environmental supervision turns measurements or contact states into clearly named room-service indications. A sensor measures a condition; the supervisory function decides whether the assigned alarm or control response is needed.
In a switchroom, water ingress, temperature, humidity and equipment-service alarms can be sent to the station controller with separate point names so an operator can identify the affected area. For this reference, the drawing identifies “Sump pump run contact” at the input and “Pump running indication” at the output. Running feedback does not prove successful drainage.
Keep sensor location, alarm thresholds, delay and monitoring coverage in the room-services schedule. An environmental alarm is a diagnostic input, not a complete assessment of electrical equipment condition. 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: Sump pump run contact. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Pump running indication. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- Running feedback does not prove successful drainage.
- Keep sensor location, alarm thresholds, delay and monitoring coverage in the room-services schedule. An environmental alarm is a diagnostic input, not a complete assessment of electrical equipment condition.

## Information to show or reference

- Label the source and connection reference for sump pump run contact.
- Identify the destination and defined state of pump running indication.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: Running feedback does not prove successful drainage.

## Important distinction

Running feedback does not prove successful drainage. 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

- Representation: Functional block
