Datalogger warning/alarm
Datalogger warning monitors whether actual
consumption 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.
