3 Installation
3.16. LEDs
The Power Xpert Meter contains several LEDs for health, application event status and
communication links. These LEDs provide a quick way of confirming power, application
status (event) and communication activities.
Meter LEDs
The Health LED, located on the bottom left side of the meter, will blink green at a slow
rate (1 sec on/off) when the meter has no fault conditions present. It will blink red at an
accelerated rate (twice per second) when a reboot operation is required due to a self-test
failure, 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’s
Digital Signal Processor (DSP) is running and accumulating energy. At that point, the
Health LED will blink green rapidly while the Power Xpert Meter’s Linux operting system
boots.
NOTE:
For
NOTE:
For the first minute, the Health LED will blink green rapidly. During
this time, the Power Xpert Meter accumulates energy, but does not record new min/max
values. It will blink red rapidly to indicate that changes to settings will not take effect until
the meter is rebooted. If the Health LED is off continuously, this indicates the power is off
or an abnormal condition exists. If the Health LED is on continuously, this indicates an
abnormal 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 there
are unacknowledged events in the Power Xpert Meter’s Events list. After the events are
acknowledged 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 LEDs
The blue Power LED, (located in the center of the PXMPS-1 faceplate, is lit whenever
power 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 solid
state relay #1. This red LED can be used with optical standards.
Display LEDs
The Green Health LED located on the Display unit will respond as stated above for every
meter connected to the display regardless of how many meters are connected, one or
sixteen. The Green Health LED on the face of the meter is only reporting the health of
that specific meter unit.
