4.2.5. Gateway Board Status LEDs
The Gateway has four LEDs: a General Status LED,
an Alarm LED, an RS485 I/O Net Status LED, and a
Receiver Bus Status LED (
4.2.5.1. The General Status LED
The General Status LED light flashes green once
every second to indicate it is powered up.
4.2.5.2. The Alarm LED
The Alarm LED (red) indicates when an alarm
condition exists for the Gateway. There are five
possible LED states, each of which indicates a
different condition.
• OFF
-
No alarm conditions are active, and the
Gateway is functioning normally.
• Flashes 4 times/second
-
There is a problem
with the physical hardware (ROM) of the
Gateway board. The board may need to be
replaced.
• Flashes 2 times/second
-
There is no user
configuration on this Gateway, no RLDS units
are commissioned in its memory, and it is
essentially in an empty state. This LED state
will occur when the board is first powered up
on-site.
• Flashes 1 time/second
-
The Gateway is not
communicating with the area controller due to
a possible RS485 I/O Network or controller
failure.
• ON with no flashing (steady)
-
One or more of
the RLDS units is offline. If all are offline,
check the wiring. If just one is offline, check the
RLDS controller.
4.2.5.3. RS485 I/O Network Status LED
The RS485 I/O Network Status LED flashes
orange to indicate traffic on the I/O Network
(between the Gateway and the site controller). If this
light does not come on at all and the Alarm LED is
flashing once per second, there is a problem with the
RS485 I/O Network or the area controller.
4.2.5.4. Receiver Bus Network Status LED
The Receiver Bus Network Status LED blinks
orange each time the RLDS Gateway sends a message
on MODBUS. However, when the Gateway receives
a message from the RLDS units, the LED will flash
brightly for 1/2 second.
If the Gateway has RLDS configurations in
memory and is communicating properly, you should
see this LED flash brightly several times within the
course of a few minutes.
