Alert title
Possible cause
Recommended actions
A115
No External Input or
Polled Data
The connection to an external
measurement device has failed. No
external data is available.
•
Verify that the external device is operat-
ing correctly.
•
Verify the wiring between the transmit-
ter and the external device.
•
Verify the HART polling configuration.
A116
Temperature Over-
range (API Referral)
The measured temperature is out-
side the range of the API table.
•
Check your process conditions against
the values reported by the device.
•
Verify the configuration of the API refer-
ral application and related parameters.
See
.
A117
Density Overrange
(API Referral)
The measured density is outside the
range of the API table.
•
Check your process conditions against
the values reported by the device.
•
Verify the configuration of the API refer-
ral application and related parameters.
See
.
A118
Discrete Output 1
Fixed
The discrete output has been con-
figured to send a constant value.
•
Check whether the output is in loop test
mode. If it is, unfix the output.
A120
Curve Fit Failure
(Concentration)
The transmitter was unable to cal-
culate a valid concentration matrix
from the current data.
•
Verify the configuration of the concen-
tration measurement application.
A121
Extrapolation Alert
(Concentration)
The line density or line temperature
is outside the range of the concen-
tration matrix plus the configured
extrapolation limit.
•
Check your process conditions against
the values reported by the device.
•
Verify the configuration of the concen-
tration measurement application.
A122
Pressure Overrange
(API Referral)
The line pressure is outside the
range of the API table.
•
Check your process conditions against
the values reported by the device.
•
Verify the configuration of the API refer-
ral application and related parameters.
See
.
A132
Sensor Simulation
Active
Sensor simulation is enabled.
•
Disable sensor simulation.
A133
EEPROM Error (Dis-
play)
There is a memory error in the dis-
play module.
•
Cycle power to the meter.
•
Replace the display module.
•
Contact Micro Motion.
A134
Tube-Case Tempera-
ture Difference
Overrange
The difference between the case
temperature and the fluid tempera-
ture is greater than 20 °C.
•
Check for process upsets. Changes to
line temperature may not be immedi-
ately reflected in case temperature.
•
Install a thermal insulation jacket.
•
Contact Micro Motion.
A136
Incorrect Display
Type
An incorrect display module has
been installed on the device. This
may cause a safety violation in haz-
ardous areas.
•
Replace the installed display module
with an appropriate display module.
