EBTH Cell temperature over/
under user alarm limit.
Probable Cause
Device
PTS Cell has not been
calibrated with present
amplifier assembly.
EQS Field device needs to be
calibrated.
STT Transmitter type not sup-
ported by STT terminal
revision level.
PTS Damage to cell
characterization board.
PTS Cell temperature over/
EQS under user alarm limit.
PTS Cell temperature input is
over/under factory speci-
fied limits.
STT Cancel key pressed
before function was com-
pleted.
STT Noisy signal.
TROUBLESHOOTING
(continued)
Corrective Action
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.
Correct temperature problem.
Change alarm value. Refer to configuration
procedures for EBTH TEMPERATURE
TRANSMITTER in Appendix B.
Corrective Action
Calibrate the field device. Refer to the
calibration section of the appropriate PTS
pressure transmitter instruction.
Calibrate the field device. Refer to the
calibration section of the appropriate
EQS temperature transmitter instruction.
Consult ABB to obtain latest STT terminal
revision.
Turn the STT terminal off and then on. If
error still exists, replace cell (refer to
repair/ replacement section of the appro-
priate product instruction for procedure).
Correct temperature problem.
Change alarm value. Refer to configura-
tion procedures for EQS TEMPERA-
TURE TRANSMITTER in Appendix C or
PTS PRESSURE TRANSMITTER
Appendix E.
Remove the source of temperature
extreme.
Try function again.
Check terminal wiring and eliminate
source of noise.
