Indication and Troubleshooting Tips
Indicates normal operation
Indicates normal operation
If low power; could be under voltage or the microprocessor has
malfunction. Measure for the expected value range. For more
information, refer to Installation, Operation, and Maintenance:
• Tracer® UC400-B Programmable Controller (BAS-SVX48*-EN)
• Symbio™ 400-B Programmable Controller (BAS-SVX093*-EN)
If malfunction; un-power and then re-power unit to bring the
unit back up to normal operation.
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.
Indicates power is OFF or there is a malfunction
OFF or malfunction; cycle the power. For more information,
refer to Installation, Operation, and Maintenance:
• Tracer® UC400-B Programmable Controller (BAS-SVX48*-EN)
• Symbio™ 400-B Programmable Controller (BAS-SVX093*-EN)
Blinks at the data transfer rate when the unit transfers data to
other devices on the link
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
Indicates that the controller is not detecting communication
Not lit; cycle the power to reestablish communication
Indicates controller is operating normally
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
Indicates that a relay output is de-energized or no power to the
board
Not lit; cycle power to reestablish communication

Notes
When powering the UC400-B/Symbio™ 400-B 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).
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.
For more information, refer to Installation, Operation, and
Maintenance:
• Tracer® UC400-B Programmable Controller (BAS-SVX48*-EN)
• Symbio™ 400-B Programmable Controller (BAS-SVX093*-EN)
When the UC400-B/Symbio™ 400-B is placed into boot
mode, the system will not run any applications such as
trending, scheduling, and TGP2 runtime. The controller will be
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.
If the user is currently powering the UC400-B/
Symbio™ 400-B 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 the user command it to be ON? If yes, see the Marquee
LED at the top of this table. For more information, refer to
Installation, Operation, and Maintenance:
• Tracer® UC400-B Programmable Controller (BAS-SVX48*-EN)
• Symbio™ 400-B Programmable Controller (BAS-SVX093*-EN)
