LM10 Motor Protection System

Chapter 1: Introduction

1.1Description

1.1.1 The LM10 Relay

The GE Multilin LM10 Motor Protection System is a modular device designed to protect motors from various fault conditions. This device interfaces with a DeviceNet network. The network will monitor and control the relay status and functions. The relay also has the capability of operating in a standalone mode. Configuration can be accomplished via DIP switches on the front of the relay.

Additionally, the relay has an interface port to communicate to the LM10 programming and display unit (PDU). The PDU is a self-contained device consisting of a membrane switch keypad, a liquid crystal display (LCD), and control electronics for communication with the relay. This unit provides a method of configuring and monitoring the LM10. The PDU incorporates an RS232 interface with a proprietary communications protocol.

DeviceNet is a registered trademark of Open DeviceNet Vendor's Association (ODVA).

OVERVIEW

CHAPTER 1: INTRODUCTION

1.2Overview

1.2.1 Features

The LM10 Motor Protection System is a microprocessor-based unit. It takes a ‘snapshot’ image of the three phases of current, one phase of voltage, and ground. The data is then applied to the algorithms and compared to the device's configuration information. Based on the result of the comparison, the relay may trip one or more of the on-board control relays. When applicable, indicators will be illuminated to show the status of the device. Additionally, up to ten trip events will be stored in non-volatile memory.

The LM10 auxiliary communications port to the PDU is an RS232 interface using a standard four-pin RJ11 style cable. This port will allow the PDU to obtain and display any of the real-world data that is contained in the relay as well as to configure the relay.

The LM10 Motor Protection System supports the DeviceNet protocol and can be interfaced with the PLC DeviceNet mastercard or DCS Scanner card. It supports Polled, Change of State (COS), Cyclic I/O Messaging, and Explicit Messaging.

1.2.2Current and Voltage Inputs

The relay has inputs for two sets of three-phase current transformers (CTs) and one ground CT. One set will allow for custom 27 A and 90 A CT sensor packs to be connected; the other will allow for 75 to 800:5 A ratio CTs. Dual speed motors will require two separate CTs connected in parallel.

A 100:1 A core-balance CT or 20 A ground fault sensor pack can be connected to the ground CT terminals for ground current measurement.

Provisions have been made to support various CTs for the three-phase measurements.

Voltage input from the control power transformer (CPT) is conditioned and measured by the analog-to-digital converter to determine supply voltage. This signal, in conjunction with the current, is used to calculate power and power factor.

1.2.3Relay Outputs

The LM10 Motor Protection System contains 4 on-board Form-C relays with NEMA C150 pilot duty ratings. Two relays should be used to control the coils of motor contactor and one to annunciate ground fault status. An additional programmable relay is available for fault status indications.

The two control relays are labeled “RUN 1” and “RUN 2”. These relays are enabled on command from the control logic. If the LM10 detects a fault condition the relays will be deenergize, causing the motors to shut down.

The ground fault relay is energized on detection of a ground fault. Upon correction of the ground fault condition, the relay will be de-energized. The output contact can be used to trip a breaker or annunciate to other devices.

The programmable trip relay is energized when the programmed algorithm conditions have been met and can annunciate out to other devices.

CHAPTER 1: INTRODUCTION

OVERVIEW

1.2.4Power Supply

The LM10 Motor Protection System has an on-board power supply with a fuse that converts the AC input to the levels necessary to operate this device. The operating range is 96 to 140 V AC, nominal 120 V control power (80% to 117%). The supply has programmable auto-restart capability of up to 4 seconds. This also supplies necessary power to the PDU at a TTL.

For correct measurement of power and power factor, the control power must be connected across phase A and phase B of the three-phase power supply.

FEATURES

CHAPTER 1: INTRODUCTION

1.3Features

1.3.1 Programming and Display Unit

The main task of the programming and display unit (PDU) is to provide status information to a local user. The PDU can display the requested parameter(s) on the LCD in either English or Spanish. Additionally, the PDU can be used to configure the LM10 via the RS232 serial communications port.

1.3.2LED Indicators

The LM10 has five (5) LEDs on the front panel. They function as follows:

•Module Status (MS): This two-colored LED is used for the DeviceNet module status. Its function is defined in the DeviceNet specification.

LED State	Description
Off	No power
Green	Device operational
Red	Unrecoverable fault

•Network status (NS): This two-colored LED is used for the DeviceNet network status. Its function is defined in the DeviceNet specification.

LED State	Description
Off	No power / not online
Flashing green	Online, not connected
Green	Link OK, online, connected
Flashing red	Connection timeout
Red	Critical link failure

•Overcurrent (OC): This red LED is illuminated when the relay detects an overcurrent condition in one or more of the power phases.

•Ground Fault (GF): This red LED is illuminated when the relay detects a ground fault condition.

•Current Unbalance (CUB): This red LED is illuminated when the relay detects a current unbalance between the power phases.

1.3.3Switches

The following switches are located on the front panel of the LM10. Changes to switch settings will not take effect until power is cycled (on-off).

All other relay features (e.g., the CT sensor pack) can only be programmed via DeviceNet or the RS232 configuration port.

•MAC ID: Two rotary DIP switches are used to set the DeviceNet MAC ID. Each unit on the DeviceNet network requires a unique MAC ID. The valid ID range is from 0 to 63, with a factory default of 0. Cycle power after any switch changes.

CHAPTER 1: INTRODUCTION

FEATURES

•Baud rate: This two-position DIP switch is used to select the DeviceNet baud rate. The valid rates are 125K, 250K and 500K bits per second. The DIP switch is defaulted to 125K baud rate when shipped.

Baud Rate	DIP Switch Position
125 kbps	down - down
250 kbps	up - down
500 kbps	up - up

Changes to switch settings will not take effect until the next power cycle.

•Trip Class (TC): NEMA overload trip class is selected using a rotary DIP switch. Valid settings are Class 10, 15, 20, or 30. To set the trip class, align the screwdriver slot with the desired value. Do not use the triangle marker on the DIP switch. A screwdriver with a nominal blade width of 0.094 to 0.175 inches should be used. Smaller blades could allow the switch to be set in an invalid position.

Changes to switch settings will not take effect until power is cycled.

Display

Liquid crystal display: four lines of 16 characters per line.

Status

The status sub-menu can display current, motor status, Run 1 and Run 2 data, faults, MAC ID, baud rate, and overload class.

Reset

The relay can be reset from the PDU, pushbutton, or the LAN.

Mounting Flexibility

The relay can be attached to the PDU without hardware to facilitate door mounting.

LEDS

One green LED power indicator and a flashing red trip LED to indicate over/undercurrent, current unbalance, ground fault, under/overvoltage, and trip command.

CONFIG

The relay parameters are programmed via the CONFIG button. The CONFIG sub-menu is similar to the status menu, and allows the user to change relay parameters: CT ratio, PT ratio, fault settings, and time delays.

History

Displays the last ten (10) trip records. The conditions at the time of fault are displayed and can be scrolled through using the UP/DOWN arrow keys.

3.2.2History Record and Status Screens

See Keypad on page 3–19 for details on the history record and status screens.

3.2.3Configuration Menu

See Keypad on page 3–19 for details on the configuration menu list. The configuration menu is used to set all the programmable parameters outlined in Configuration Settings on page 4–29.

•CTs and CPTs Sub-menu: This menu and its sub-menus are used to select Control Power Transformer (CPT), Current Transformer (CT) or Sensor Pack, and the number of turns through the CT.

•Starter Type Sub-menu: This menu is used to select Motor Starter Type.

•Run 1 and Run 2 Setup Sub-menus: This Run 1 menu is used to set full load current (FLA) for Run 1. It also contains sub-menus for enable/disable and configures the following optional faults: ground fault, jam, stall, current unbalance, and load loss.

Each fault is configurable not only in magnitude, but also in time delay in which that condition is allowed to exist before the LM10 trips.

The Run 2 Setup menu is laid out identically to Run 1 menu. Unless a custom motor type is selected, Run 2 setup is not necessary.

The full-load current will auto-populate if “Two-Speed” is selected. 2S1W will provide a 4:1 ratio of the FLA and 2S2W will set the FLA to a 2:1 ratio.

Only one relay at a time can be on.

• Time Delays Sub-menu: The following time delays are set using this menu:

Auxiliary sense 1 (contactor closed; opened detects welded contacts)

Auxiliary sense 2 (contactor closed; opened detects welded contacts)

Run 1 to Run 2 (delay between forward and reverse or between speeds)
