Table 25 - ArmorStart LT Status and Diagnostics Indicators
Indicator Description Color_1 Color_2
PWR LED The bicolor (green/yellow) LED shows the
state of the control voltage. When LED is
off, switched and/or unswitched power is
not present. Solid green is illuminated when switched
and unswitched control power is within its
specified limits and has the proper polarity. Solid yellow is illuminated when switched
or unswitched control power is outside its
specified limits or has incorrect polarity.
Flashing yellow indicates line voltage is not
present (Bulletin 294 units only).
RUN/FLT LED The bicolor (green/red) LED combines the
functions of the Run and Fault LEDs. Solid green is illuminated when a Run
command is present. The LED will blink red in a prescribed fault
pattern when a protection fault (trip)
condition is present. See table for fault
blink patterns.
NS – Network Status
LED The bicolor (green/red) LED indicates the
status of the CIP network connection. See
Network Status Indicator for further
information.
Flashing bicolor (red/green) indicates a
self-test on power up. Flashing green indicates an IP address is
configured, no CIP connections are
established, and an Exclusive Owner
connection has not timed out.
Steady green indicates at least one CIP
connection is established and an Exclusive
Owner connection has not timed out. Flashing red indicates the connection has
timed out. Steady Red indicates a duplicate
IP Address detected.
LS1 and LS2 – Link
Status LEDs The bicolor (green/yellow) LED shows the
activity/link status of each EtherNet/IP
port. Solid green is illuminated when a link has
been established at 100 Mbps. Solid yellow is illuminated when a link has
