ERROR MESSAGES
5 - 4
MORE STATUS AVAIL. All HART HART device has more
status available, but is
not understood by the
STT because the device
is not supported by the
STT.
Contact ABB technical support.
NON-PV OUT OF
LIMIT
All HART Process applied to the
nonprimary variable is
outside the operating lim-
its of the field device.
Correct process input.
OPEN SENSOR
EBTH
Field device temperature
transducer failure.
Replace the temperature transducer. (i.e.,
thermocouple, RTD).
Field device temperature
transducer not con-
nected.
Connect the proper transducer
(i.e., thermocouple, RTD).
PV OUT OF LIMITS
All HART Process applied to the
transmitter is outside the
transmitter limits.
Correct the process input.
RAM FAILURE
PTH
EBTH
Internal RAM failure.
Replace electronics. Refer to the repair/
replacement section of the appropriate
product instruction.
REF JUNCTION
FAILURE
EBTH
Reference junction (CJC)
failed.
Replace the amplifier assembly.
SHORTED SENSOR
EBTH
Temperature transducer
failure.
Replace temperature transducer.
Field wiring shorted
Find and correct the wiring problem.
SPAN ZERO KEY
ERROR
PTH
Misoperation of EZ CAL
option.
Try again.
Damaged EZ CAL option. Replace EZ CAL option. Refer to the repair/
replacement of the appropriate PTS product
instruction.
Damaged amplifier
assembly.
Replace amplifier assembly. Refer to the
repair/replacement section of the appropri-
ate PTS product instruction.
TEMP OFFSET
WARNING
TB82
High or low temperature
offset
Verify sensor wiring connections and
inspect cable for shorts. Remove all poten-
tial shorts to ground, conduit or metals.
Verify that sensor had 10 to 15 min. to accli-
mate to temperature environment to which it
was calibrated.
Disconnect temperature compensator leads
from transmitter and measure resistance.
Replace sensor with spare when transmitter
does not accept calibration values.
