Publisher: Elora Grid
Updated: 2026-11-03
Lookup label: MLP
Drawing use: Schematic
Reference families: Manufacturer

Representation: Functional block
Installation focus: microgrids
Input: System recovery and motor availability
Output: Reacceleration permission

Identifies the documented permission for the assigned motor loads to reaccelerate after a disturbance.

## In plain English

### What this block does

Identifies the documented permission for the assigned motor loads to reaccelerate after a disturbance.

### A simple example

In a microgrid island, the controller can disconnect lower-priority loads when a source is lost and later request restoration when the documented reserve and stability conditions permit it. For this reference, the drawing identifies “System recovery and motor availability” at the input and “Reacceleration permission” at the output. Motor and system dynamic limits require assessment.

### What the drawings help you do

Start at the named input: System recovery and motor availability. Identify its source device or document and the state represented on the drawing. Follow the named output: Reacceleration permission. Cross-reference its destination and separate the command from confirmation that the equipment responded.

### Terms

- Input: System recovery and motor availability
- Output: Reacceleration 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

Identifies the documented permission for the assigned motor loads to reaccelerate after a disturbance. Load management balances the available electrical supply against the loads that remain connected. Shedding, restoration, priority and proof of disconnection are separate control functions and should remain traceable to individual load groups.
In a microgrid island, the controller can disconnect lower-priority loads when a source is lost and later request restoration when the documented reserve and stability conditions permit it. For this reference, the drawing identifies “System recovery and motor availability” at the input and “Reacceleration permission” at the output. Motor and system dynamic limits require assessment.
Identify each load group, priority, measured contribution and feedback. Shedding amounts, operating times and restoration conditions require the approved power-management design and the actual connected-load data. 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: System recovery and motor availability. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Reacceleration permission. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- Motor and system dynamic limits require assessment.
- Identify each load group, priority, measured contribution and feedback. Shedding amounts, operating times and restoration conditions require the approved power-management design and the actual connected-load data.

## Information to show or reference

- Label the source and connection reference for system recovery and motor availability.
- Identify the destination and defined state of reacceleration permission.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: Motor and system dynamic limits require assessment.

## Important distinction

Motor and system dynamic limits require 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
