9.1 Troubleshooting instructions
Fault conditions that arise during operation are immediately identified by Dosimass and signaled and
output in different ways:
• Via a light-emitting diode (LED) on the electronics (

• Via the status output (

• Via error messages in the "FieldCare" operating program:
– System error messages (

– Process error messages (

9.2 Types of error
9.2.1 Type of error
Errors that occur during commissioning or measuring are signaled and/or displayed immediately. If
two or more system or process errors occur, the error with the highest priority is the one shown on
the display.
The measuring system distinguishes between two types of error:
•
System error: This group includes all device errors, for example communication errors, hardware
errors, etc.

• Process error: This group includes all application errors, for example partially filled pipes

Note!
System and process errors are only differentiated in detail in the FieldCare operating program but
not by error signalizing via the LED or the status output.
9.2.2 Error message types
When system/process errors occur, the measuring system also differentiates between fault or notice
messages. Serious system errors, e.g. module defects, are always identified and signaled as "fault
messages" by the measuring device.
Notice message:
• Display:
– LED flashes red/green alternately (approx. once a second)
– FieldCare operating program: display via SN or PN (N = Notice)
• The error in question has no impact on the pulse output of the device.
Fault message:
• Display:
– LED flashes red (approx. three times a second)
– FieldCare operating program: display via SF or PF (F = Error, Fault)
• The response of the pulse output can be defined by means of the relevant function in the function
matrix.

Note!
• Fault and notice messages are differentiated during fault diagnosis via the LED and in the
FieldCare operating program but not by the status output.
• For security reasons, error messages should be output via the status output.
