ERROR MESSAGES
5 - 3
CELL TEMP OVR/
UNDR LMT
PTH
Cell temperature input is
over/under factory speci-
fied limits.
Remove the source of temperature
extreme.
COLD START
All
Reset or self-test of the
field device occurred or
power was removed and
reapplied to the device.
No corrective action required. Notification
only.
CONFIG CHANGED
All HART Parameters of configura-
tion changed
Perform RESET CONFIG.
DYNMC TEMP MST
FAIL
PTH
Dynamic temperature
input exceeded limits set
at factory.
NOTE:
The temperature of the
high side of the cell with respect
to the low side of a PTH.
Output may no longer be accurate. Remove
source of temperature shift.
ELEC TEMP OVR/
UNDR RANG
PTH
Electronics temperature
is outside the factory
specified limit.
Remove the source of the temperature
extreme.
ELECT TEMP MST
FAIL
PTH
Hardware failure of
on-board temperature
sensor.
Replace amplifier assembly. Refer to repair/
replacement section of the appropriate
product instruction.
FIELD DEVICE IN
MULTIDROP MODE
All HART Device is in digital mode. Command cannot be performed. Configure
device for analog mode (point-to-point).
FIXED OUTPUT
MODE
All HART STT terminal turned off
while the 4 to 20 mA out-
put was being calibrated.
Power down the transmitter and power up
the transmitter.
Transmitter cannot exe-
cute command because
of fix output.
Take transmitter out of fix output. Refer to
INPUT OVER RANGE
PTH
EBTH
Input out of range.
Reduce process input, or configure proper
limits. To verify proper limits use
to view the limits.
Input greater than cell
specification.
Reduce input pressure.
INPUT UNDER
RANGE
PTH
EBTH
Input exceeds the cell
specification.
Increase input pressure.
Input value too low.
Increase process input, or configure proper
limits. To verify proper limits use
to view the limits.
MAIN EEPROM
FAILURE
PTH
EBTH
Memory problem.
Remove power from the field device and
reapply. If problem persists replace the
amplifier assembly. Refer to repair/replace-
ment section of the appropriate product
instruction.
