Page 56 IM02601004E www.eaton.3 Installation3.16. LEDsThe Power Xpert Meter contains several LEDs for health, application event status andcommunication links. These LEDs provide a quick way of confirming power, applicationstatus (event) and communication activities.Meter LEDsThe Health LED, located on the bottom left side of the meter, will blink green at a slowrate (1 sec on/off) when the meter has no fault conditions present. It will blink red at anaccelerated rate (twice per second) when a reboot operation is required due to a self-testfailure, an internal fault, an invalid configuration, or a communication fault during power-up initialization.NOTE: During initialization, the Status LED will blink red in patterns of 3 until the meter’sDigital Signal Processor (DSP) is running and accumulating energy. At that point, theHealth LED will blink green rapidly while the Power Xpert Meter’s Linux operting systemboots.NOTE: For NOTE: For the first minute, the Health LED will blink green rapidly. Duringthis time, the Power Xpert Meter accumulates energy, but does not record new min/maxvalues. It will blink red rapidly to indicate that changes to settings will not take effect untilthe meter is rebooted. If the Health LED is off continuously, this indicates the power is offor an abnormal condition exists. If the Health LED is on continuously, this indicates anabnormal condition.The Status LED, located on the bottom left side of the meter (next to the Health LED),will be either green or red. Normally be solidly green, but will slowly blink red when thereare unacknowledged events in the Power Xpert Meter’s Events list. After the events areacknowledged or cleared, the Status LED will return to a solid, green state. If the LED re-peats a series of three red blinks, the meter is in factory test mode. See the Troubleshoot-ing chapter for more information.Card LEDsThe blue Power LED, (located in the center of the PXMPS-1 faceplate, is lit wheneverpower is applied to the meter. Before servicing the meter, ensure that this LED is not lit.The following ports have transmitting LEDs and receiving LEDs that blink when transmit-ting or receiving information respectively:• LAN/WAN 10/100 T RJ45 (CE2)• COM2 RS485 (CE3)• COM3 RS232 (CE4)• COM3 Modem (CE5)• Local Configuration 10/100 T RJ45 (CM1)• COM1 RS485 (CM3)• COM0 Display (CM5)The Ethernet ports support a link LED and combine the TXRX function as a bicolor LED.The PXMIO Card has an S1 LED at the bottom of the card that follows the status of solidstate relay #1. This red LED can be used with optical standards.Display LEDsThe Green Health LED located on the Display unit will respond as stated above for everymeter connected to the display regardless of how many meters are connected, one orsixteen. The Green Health LED on the face of the meter is only reporting the health ofthat specific meter unit.
