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).
