1.1 Description
LM10 Motor Protection System
Chapter 1: Introduction
Introduction
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).
LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 1–1
OVERVIEW CHAPTER 1: INTRODUCTION
1.2 Overview
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.
1.2.2 Current 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.
1.2.3 Relay 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
1.2.4 Power 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
1.3 Features
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.
1.3.2 LED 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
1.3.3 Switches
• 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.
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.
1–4 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL
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

When the LM10 contact inputs are connected to the remote devices for the input signal via long
cables, induced voltages may be present at the input terminal of LM10 relay. The contact input
status could be detected as closed if the induced voltages are greater than 33V. Under these
situations it is recomonded to use interposing relay or to connect a resistor across the LM10
contact input terminal and ground to provide path for the induced voltages to the ground.

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)
