XM/SM/ cations. Message will not
XE affect operation but could
mean temperature perfor-
mance is out of range.
PTS Local heat or cold source

BCN On-board temperature
EQN sensor failure.
XM/SM/ Process value over/under
XE alarm limit.
BCN Input signal not at speci-
EQN fied level.
EQS
PTS
TBN
XM/SM/ Coil excitation has
XE stopped.
XM/SM/ Process value over/under
XE alarm limit.
XM/SM/ Power was lost to device.
XE
STT No configuration exists in
the STT terminal
memory.
STT STT terminal not
connected to a device.
XM/SM/ The current configuration
XE is calling to use the empty
pipe detector which
requires and optional
board.
AVS Pressure on output port
01 or 02 is too high.
AVS The position transmitter
(transducer) has failed.

Corrective Action
Recalibrate the field device. Refer to the
appropriate calibration section for the
device type.
NOTE: Uncalibrated field devices may have this error
until calibrated.
Eliminate or reduce temperature extreme
of the electronics.
Replace input board. Refer to repair/
replacement section of the appropriate
product instruction.
Correct process problem.
Change alarm value. Refer to
MODIFY CONFIGURATION
Appendix I.
Correct signal and recalibrate. Refer to
the appropriate calibration section for
details.
Check wiring of excitation signal and ref-
erence signal. If both are OK, call service.
Correct process problem.
Change alarm value. Refer to
MODIFY CONFIGURATION
Appendix I.
Check for loose wiring.
Restore totalizers to known values if lost.
Create configurations. Refer to
ING PROCEDURES in Section 4.
Check STT terminal lead connections.
Verify proper field device wiring. Refer to
the installation section of the appropriate
product instruction.
Add empty pipe detector option, or turn
empty pipe detection off in the configura-
tion.
Check air pressure supply.
Refer to the repair/replacement section of
the appropriate positioner product
instruction.
