Device Status
Description
Recommended Actions
Electronics
Failure
An electronics error has occurred
that could impact the device
measurement reading.
1. Reset the device.
2. Reconfirm all of the configuration
items in the device.
3. Contact a service center if the
condition persists.
Sensor Failure
The process temperature sensor
cannot be read.
1. Check the sensor wiring
connections and configuration.
2. Replace the temperature sensor.
3. Contact a service center if the
condition persists.
Process Sensor
Out of Limits
The process temperature sensor is
out of the allowed operating range.
1. Verify that the appropriate sensor is
selected for the application.
2. Replace the temperature sensor
with an appropriate sensor type for the
process temperature range.
3. Contact a service center if the
condition persists.
Process Sensor
Saturated
The process temperature value has
saturated and can no longer track
the actual process temperature
measurement.
1. Verify that the process temperature
is within the valid operating limits of the
temperature sensor and device.
2. Replace the temperature sensor.
3. Contact a service center if the
condition persists.
Sensor High
Alert
The temperature measurement has
gone above the high alert configured
by the user. The alert is active.
1. Check the process sensors and
process conditions.
2. Check the user configured alerts.
Sensor Low
Alert
The temperature measurement has
dropped below the low alert
configured by the user. The alert is
active.
1. Check the process sensors and
process conditions.
2. Check the user configured alerts.
Process Sensor
Excessive EMF
There is excess voltage on the
process temperature sensors.
1. Check the sensor wiring and
connections.
2. Replace the process sensor.
3. Contact a service center if the
condition persists.
Cold Junction
Temperature
Out of Limits
The cold junction compensation
temperature is outside of the allowed
operating limits.
1. Verify that the electronics
temperature is within the device
operating range.
2. Contact a service center if the
condition persists.
Electronics
Temperature
Out of Limits
The electronics temperature is
outside of the operating range of the
transmitter.
1. Make sure the device is installed in
an environment within the device
operating temperature range.
2. Contact a service center if the
condition persists.
Electronics
Temperature
Failure
The electronics temperature is
beyond the failure limits of the
transmitter.
1. Make sure the device is installed in
an environment within the device
operating temperature range.
2. Contact a service center if the
condition persists.
Simulation
Active
The device is in simulation mode
and may not report actual
information.
1. Disable any simulation values.
2. Contact a service center if the
condition persists.
