Datalogger warning/alarm
Datalogger warning monitors whether actual con‐
sumption on Totalizer 1 is on end of log interval or
above/below the limit settings.
The warning has no influence on the flowmetering.
Check data logger values and consumption limit
(via PDM parameter 602)
Errors "F 1" to "F 4" affect the performance of the meter and the flowmeter may stop measuring.
Errors "F 1" and "F 2" disappear when the alarm condition is corrected.
Errors "F 5" to "F 9" are only warnings and do not affect the measurement, but they will influence
the outputs.
The error indications disappear when the alarm conditions are corrected and a reset via the
communication interface has been carried out.
Example
Error code "F 1 2" in the display indicates a combination of error codes "F 1" and "F 2".
Possible causes:
● Empty pipe
● Path 1 and path 2 cables defective
● Path 1 and path 2 cables not connected
● Transducers defective

Diagnosing with PDM
SIMATIC PDM is a suitable tool for diagnosing the device. You can use SIMATIC PDM to read
all parameters available in FUS080 to a table for analyzing offline, view online/actual process
values and online/actual diagnostic information.
Requirements
The following procedure must be completed before diagnosing:
● Connection of Modbus interface via PC and IrDA, see also Commissioning via PDM
● Installation of PDM and FUS080 PDM driver, see also Installing the device driver
