Operating Instructions, 05/2020, A5E41864807-AB
Cause/Remedy
A critical measurement error was detected at the internal voltage
reference.
Reconnect or repair the sensor.
If the problem persists, contact Technical Support.
A critical measurement error was detected at Input 1.
Reconnect or repair the sensor.
If the problem persists, contact Technical Support.
A critical measurement error is detected at Input 2.
Reconnect or repair the sensor.
If the problem persists, contact Technical Support.
A critical measurement error is detected on ground voltage offset to
terminal 3.
Reconnect or repair the sensor.
If the problem persists, contact Technical Support.
Device LED flashing red: The configuration is temporarily invalid for
less than 3 seconds, for example during parameter download.
No further action is required by the user.
Device LED lights permanently red: The configuration is temporarily
invalid for more than 3 seconds, for example if the download is
paused.
Correct and/or resend the configuration.
The main program was inadvertently reset.
Correct and/or resend the configuration.
If the problem persists, contact Technical Support.
Process value has reached the sensor limit.
Review process conditions versus product specifications.
A process value that is not mapped to the primary variable has
reached the sensor limit.
Review process conditions versus product specifications.
The device is in simulation mode and one or more of its device varia‐
bles are not representative of the process.
Disable the simulation to return to normal operation.
