Advanced Motor Health Report
The Multilin Agile health report provides a quick snapshot of the motor operating and diagnostic information in an easy way to allow users to make decisions about health of the motor. Based on the graphical representation and trend values of the motor historical data gathered by the Multilin Agile, users can quickly identify process issues and maintenance requirements before damage occurs and costly repairs are required.
The motor health report quickly provides a motor operation summary with detailed information in seven categories.
- Device Overview
- Status Overview
- Trip Summary
- Motor Operating History
- Motor Starting Learned Data
- Motor Start Records
- Motor Stopping/Tripping
Advanced Communications
Three communication ports are standard: a rear serial port providing remote communications, a front USB port and rear Ethernet for device configuration and management.
Two additional Ethernet ports can be ordered to achieve Ethernet communication redundancy.
Supported Communication Protocols Include:
- Modbus (RS485 serial or Ethernet)
- IEC 60870-5-103
- DNP 3.0 (RS485 serial or Ethernet)
- IEC 61850 Ed. 2 with concurrent serial connection
- Redundant Ethernet protocols PRP, HSR, and failover also available with dual RJ45 or dual fiber media
Flexible Hardware
- Space-saving 4U height with 4” (20TE) and 6“ (30TE) case size options
- Wide choice of opto-isolated binary inputs and output relays
- Binary inputs ESI 48-4 EB2 compliant – avoids spurious pickup from induction on field wiring
- High density I/Os in various combinations depending on case size option
- Ungrouped binary inputs for trip circuit supervision
- Field upgradeable, avoiding costly hardware change
- 6” (30TE) models can accommodate:
- 1 x RS485/IRIG-B interface
- Up to 3 x RJ45/fiber optic ports for single and redundant Ethernet plus additional engineering access
- From 11 to 30 binary inputs, and 9 to 25 relay outputs, depending on the order code
- 4” (20TE) models can accommodate:
- 1 x RS485/IRIG-B interface
- 1 x RS485 additional interface
- Up to 3 x RJ45/fiber optic ports for single and redundant Ethernet plus additional engineering access
- Up to 11 binary inputs and 11 binary outputs or 14 binary inputs and 9 binary outputs, depending on the order code
Simulation & Testing
To aid commissioning, a simulation feature is provided to test the relay’s functionality and response to programmed conditions, without the need for external AC voltage and current inputs. When placed in simulation mode, the relay suspends reading actual AC inputs, generates samples to represent the programmed phasors, and loads these samples into the memory to be processed by the relay. Normal (pre-fault), fault, and post-fault conditions can be simulated to exercise a variety of relay features. Other test operations - such as an LED lamp test for each color, contact input states, and testing of output relays - are also possible.
Application Model Selection
| Model | Hardware Base | Intended Application | Case Size |
|---|---|---|---|
| P24NB | P24N | Motor Protection (current elements only) | 20TE/30TE |
| P24DB | P24D | Motor Protection (current voltage & power elements) | 20TE/30TE |
Intuitive User interface
The front HMI hosts a fully-graphical color screen. The front panel supports start, stop, local/remote, and direct function key access, facilitating the control of connected motor and managing up to six controllable devices. These replace traditional hardwired control scheme switches and annunciation, saving on engineering time and wiring costs.
Sixteen tricolor LED lamps are available, freely configurable, in addition to four fixed-function LEDs that provide a cost-effective solution for annunciation.
Multiple language are supported with easy switching between English and an additional language on the local display without uploading new firmware.
A USB front port allows ready access by field personnel’s laptop computers.
Intuitive Graphical Display
Intuitive User interface – Compact Version
The front HMI hosts a multi-line text display which allows direct device interaction. Smart dependencies within the menu ensure that settings for unused elements are hidden.
Four tricolor LED lamps are available, freely configurable, in addition to four fixed-function LEDs which provide a cost-effective solution for annunciation.
Multiple language are supported with easy switching between English and an additional language on the local display without uploading new firmware.
A USB front port offers ready access by field personnel’s laptop computers.
