Updated: 2026-11-03
Lookup label: MPRP
Drawing use: Schematic
Reference families: Manufacturer

Representation: Functional block
Installation focus: switchgear
Input: Reset request and fault status
Output: Reset permission

Allows the documented reset request when the protection and process conditions permit it.

## In plain English

### What this block does

Allows the documented reset request when the protection and process conditions permit it.

### A simple example

In a switchroom motor-control panel, a ventilation motor can receive an automatic start request while a local selector and the motor protection determine whether the feeder is available. For this reference, the drawing identifies “Reset request and fault status” at the input and “Reset permission” at the output. Reset is distinct from a new start command.

### What the drawings help you do

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

### Terms

- Input: Reset request and fault status
- Output: Reset 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

Allows the documented reset request when the protection and process conditions permit it. A motor feeder combines switching, motor protection and an operating command. Starting permission, running feedback and protection trip are different signals even where one relay or controller processes all of them.
In a switchroom motor-control panel, a ventilation motor can receive an automatic start request while a local selector and the motor protection determine whether the feeder is available. For this reference, the drawing identifies “Reset request and fault status” at the input and “Reset permission” at the output. Reset is distinct from a new start command.
Link the motor tag to its contactor, protective device and process permissives. The control diagram must identify stop priority, feedback and restart philosophy without supplying unverified settings. 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: Reset request and fault status. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Reset permission. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- Reset is distinct from a new start command.
- Link the motor tag to its contactor, protective device and process permissives. The control diagram must identify stop priority, feedback and restart philosophy without supplying unverified settings.

## Information to show or reference

- Label the source and connection reference for reset request and fault status.
- Identify the destination and defined state of reset permission.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: Reset is distinct from a new start command.

## Important distinction

Reset is distinct from a new start command. 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
- Installation focus: Switchgear
