Marquee LEDs
Shows solid green when the unit is
powered and no alarm exists.
Indicates normal operation.
When powering the UC210 and
expansion module, the Marquee LED will
blink RED, blink GREEN (indicating
activated and controller/expansion
module are communicating), and then
stay GREEN CONTINUOSLY (indicating
normal power operation).
Shows blinking green during a device
reset or firmware download.
Indicates normal operation.
Shows solid red when the unit is
powered, but represents low power or a
malfunction.
If low power: could be lacking voltage or
the microprocessor has malfunctioned.
If malfunction: turn off power and then
re-power unit to bring the unit back up to
normal operation.
Shows blinking red when an alarm or
fault exists.
An alarm or fault condition will occur if
the value for a given point is invalid or
outside the configured limits for the
point. Alarm and fault conditions vary,
and they can be configured by the
programmer.
LED not lit.
Indicates power is OFF or there is a
malfunction.
OFF or malfunction: cycle the power.
Link and IMC
TX blinks green.
Blinks at the data transfer rate when the
unit transfers data to other devices on
the link.
TX LED: Regardless of connectivity or
not, this LED will constantly blink as it
continually looks for devices to
communicate to.
LED not lit:
Determine if, for example, a Tracer SC or
BACnet device is trying to talk to the
controller or if it is capable of talking to
the controller. Also determine if the
communication status shows down all of
the time. In addition, check polarity and
baud rate.
RX blinks yellow.
Blinks at the data transfer rate when the
unit receives data from other devices on
the link.
• ON solid yellow: indicates there is
reverse polarity.
LED is not lit.
Indicates that the controller is not
detecting communication.
• Not lit: cycle the power to reestablish
communication.
Service
Shows solid green when the LED has
been pressed.
When the UC210 is placed into boot
mode, the system will not run any
applications such as trending,
scheduling, and TGP2 runtime. The
controller is placed into boot mode if the
service pin is held in when power is
applied. In boot mode, the controller is
non-operational and is waiting for a new
main application to be downloaded.
LED not lit.
Indicates controller is operating
normally.
Binary B01
through B05
Shows solid yellow.
Indicates a corresponding binary output
has been
commanded
ON.
• Relay coil: indicates that a command
has been made to energize.
• TRIAC: indicates that a command has
been made to turn ON.
If you are currently powering the UC210
from a USB port, the Led lights will turn
ON. However, the binary outputs
will
not
be activated.
Commanded ON; As an example of
commanded ON, a command could be a
manual command such as an override or
a command could be from TGP2 based
on a list of conditions that are met telling
these outputs to turn ON.
LED not lit:
Did you command it to be ON? If yes, see
the Marquee LED at the top of this table.
LED not lit.
Indicates that a relay output is de-
energized or no power to the board.
• Not lit: cycle power to reestablish
communication.
