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.
