Using Status Leds - Honeywell SEC-H-602 Manual

USING STATUS LEDS

The Security Controller includes several LEDs that can
help determine the status of the unit. They are located in
two places: the top of the controller (visible through the
cover), and for relay outputs and serial ports, on the
bottom board (visible with cover removed). From left-to-
right these LEDs include:
• Ethernet Port LEDs
• Heartbeat LED
• Status LED
• Relay Output LEDs
• Serial Port LEDs
See Fig. 17 for the exact locations of all LEDs on the
Security Controller.
Ethernet Port LEDs
Each Ethernet port ("LAN2", "LAN1") has one green LED,
visible on the top cover.
A "LANx" LED indicates activity on that port as follows:
• Off—No Ethernet link is made
• On—Ethernet link is present, but no activity on the
LAN
• Blinking—Ethernet link is present with data activity on
the LAN.
Heartbeat LED
The "BEAT" LED is located to the right of the Ethernet
status LEDs, and is yellow. Under normal operation, this
LED should blink about once per second. If the heartbeat

STATUS
LED stays on constantly, does not light, or blinks very fast
(more than once per second), contact System
Engineering for technical support.
Status LED
The "STATUS" LED is located to the right of the heartbeat
("BEAT") LED, and is green. This LED provides a CPU
machine status check, and should remain lit whenever the
Security Controller is powered. If the STATUS LED does
not light while power is applied, contact System
Engineering for technical support.
Relay Output LEDs
Each of the four relay outputs has an LED, located near
the "C" terminal on the bottom circuit board (see Fig. 17).
Each relay output LED is lit whenever that relay is
energized by the Security Controller. See "Relay Output,"
page 18, for more details.
