GE Consumer & Industrial Multilin LM10 Motor Protection System Chapter 1: Introduction Introduction 1.1 Description 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.
OVERVIEW 1.2 CHAPTER 1: INTRODUCTION 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.
CHAPTER 1: INTRODUCTION 1.2.4 OVERVIEW 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.
FEATURES 1.3 CHAPTER 1: INTRODUCTION 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.
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 125 kbps DIP Switch Position 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.

GE Consumer & Industrial Multilin LM10 Motor Protection System Chapter 4: Functionality Functionality 4.1 Overcurrent Fault Conditions 4.1.1 Descriptions When current for any of the three phases becomes greater than the nominal full load current (FLA), the unit calculates time to trip. The FLA, trip class, CT ratio and number of passes/turns through the CT, and current input readings are taken into account. Separate algorithms are used for “cold” and “hot” motors.
OVERCURRENT FAULT CONDITIONS CHAPTER 4: FUNCTIONALITY FIGURE 4–1: Cold Motor Trip Curves FIGURE 4–2: Hot Motor Trip Curves 4–26 LM10 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL
CHAPTER 4: FUNCTIONALITY 4.1.2 OVERCURRENT FAULT CONDITIONS Trip Curves Example A trip curves example with jam and stall enabled is shown below. In this example, we have trip class 20, cold motor, with jam at 150% FLA for 120 seconds, and stall at 600% FLA for 12 seconds. FIGURE 4–3: Trip Curve with Jam and Stall Enabled The LM10 will trip on a jam or stall condition if these faults are enabled (see Run 1 and Run 2 Setup on page 4–32). The overcurrent curve cannot be disabled.
OVERCURRENT FAULT CONDITIONS CHAPTER 4: FUNCTIONALITY While the motor is in the cool-down time delay, the PDU status screen will display the fault type followed by a number decrementing from 99. When the number counts down to 0, the message “Ready to Run” will be displayed to indicate the RESET button may be pressed. Once the LM10 is successfully reset, the user may activate the run command.

CHAPTER 4: FUNCTIONALITY CONFIGURATION SETTINGS • FLA (full load current) The LM10 Motor Protection System is designed to work in conjunction with a spectrum of motor starters. Therefore it handles full load currents ranging from 1.2 to 800 amps. The correct FLA for the motor in use must be programmed for relay protection to function properly. Enter the full load current (FLA) of the motor.
CONFIGURATION SETTINGS CHAPTER 4: FUNCTIONALITY A 6% voltage unbalance equates to a roughly 25% current unbalance and will frequently cause motor damage. • LdLoss Setup (load loss setup): Load loss is based on watts, defined as follows: watts = 1.732 × average current × voltage × power factor (EQ 4.3) The power factor is determined using the phase relationship between voltage and phase C current readings.
CHAPTER 4: FUNCTIONALITY CONFIGURATION SETTINGS Other Settings Maintained off Range: on, off Other Settings Auto Restart off Range: on, off Other Settings DevNet Fault on Range: on, off Other Settings 50Hz Sys off Range: on, off Other Settings Poll Data 1 Range: 1, 2, 3, 4.

GE Consumer & Industrial Multilin LM10 Motor Protection System Appendix A A.1 DeviceNet Overview A.1.1 Description DeviceNet™ is an open low-cost digital, multi-drop network based on the reliable CAN technology to interconnect industrial devices (such as limit switches, photoelectric sensors, valve manifolds, motor starter, process sensors, panel displays, etc.) via a single network. This eliminates expensive wiring and failure due to the increase of number of connections.
DEVICENET OVERVIEW A.1.2 CHAPTER A: Controller Area Network (CAN) The Controller Area Network (CAN) is a broadcast-oriented communications protocol. DeviceNet uses CAN for its data link layer. The CAN protocol has a fast response and high reliability for demanding applications such as control of anti-lock brakes and air-bags. Devices are now available for the industrial automation market demanding stability in high temperature and high noise immunity. A.1.
CHAPTER A: A.1.4 DEVICENET OVERVIEW Explicit Messaging and Input/Output (I/O) Messaging Explicit messages contain information such as vendors, parameters, etc. of a device. This information is comparatively less important than the I/O message; as such, it is sent with a higher CAN identifier as not to disturb the exchange of I/O messages on the bus. Input/Output (I/O) messages contain the real-time I/O information of a device.
