FIELD DEVICE
CAN'T EXECUTE
COMMAND:
FBS ON-LINE
All FSK STT terminal cannot
change any transmitter
parameters while the field
bus is active.
Transmitter must be brought off-line. This
can be done from the MFC/MFP by tun-
ing the function code.
NOTE:
To bring transmitter off-line, the retainer can
be unplugged from the rack. Be aware that by doing
this, communication is lost for all other transmitters on
the bus. When the retainer is unplugged, there is a
2-minute time out period until the STT terminal will be
allowed to change parameters. After the 2-minute pe-
riod, the transmitter allows the STT terminal access.
FIELD DEVICE

COMMAND:
HARDWARE PROB-
LEM
BCN
EQN
TBN
Detected error in
hardware.
Press
to determine error and
use this table for appropriate corrective
action. If status is not more explicit, check
electronics assembly of field device.
AVS
Unspecified hardware
failure
Service unit.
FIELD DEVICE
CAN'T EXECUTE
COMMAND:
INVALID COMMAND
All FSK Incorrect syntax.
Wrong device type selected in the
configuration. Refer to the appropriate
device configuration appendix for details
about device type.
Excessive line noise.
Check line noise. Use an oscilloscope to
determine if line noise is excessive.
STT terminal failure.
Verify STT terminal is operational by
using another STT terminal that is known
to be operational.
FIELD DEVICE
CAN'T EXECUTE
COMMAND:
LOCKOUT ENGAGED
All FSK Unable to configure or cal-
ibrate. Hardware lock
active.
Refer to the device product instruction for
details about the configuration lockout
jumper.
FIELD DEVICE
CAN'T EXECUTE:
DATA
OUT OF RANGE
All FSK Transmitter sent data that
is out of acceptable range.
Press
to verify the parameters of
the configuration and consult the appro-
priate device instruction for correct
parameters.
FIELD DEVICE
CONFIGURATION
DOES NOT MATCH
STT'S
All FSK Configuration of the trans-
mitter does not exactly
match the corresponding
configuration in the STT
terminal.
Rerange was executed without updating
the STT terminal configuration.
Perform
GET CONFIG
. Refer to
NOTE:
The positioner will change the installed option
flags if they are incorrect in the transmitted configura-
tion. This error will appear if the configuration is not re-
loaded by the STT terminal.
FIELD DEVICE
MAIN
ELECTRONICS
EEPROM FAILURE
BCN
EQN
TBN
Memory problem.
Reconfigure and recalibrate the transmit-
ter. Refer to the appropriate configuration
and calibration sections in this instruction
for the transmitter type.
EQS
PTS
Memory problem.
Remove power from the field device and
reapply. If problem persists replace the
amplifier assembly. Refer to repair/
replacement section of the field device
product instruction.
