ERROR MESSAGES
5 - 5
TEMP SLOPE
WARNING
TB82 High or low temperature
slope
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.
USER TEMP HI/LO
ALARM
EBTH Cell temperature over/
under user alarm limit.
Correct temperature problem.
Change alarm value. Refer to configuration
procedures for EBTH TEMPERATURE

CALIBRATION
REQUIRED
PTS Cell has not been
calibrated with present
amplifier assembly.
Calibrate the field device. Refer to the
calibration section of the appropriate PTS
pressure transmitter instruction.
EQS Field device needs to be
calibrated.
Calibrate the field device. Refer to the
calibration section of the appropriate
EQS temperature transmitter instruction.
