Failure
Constant Temp. Buf. not
cleared
Cause:
The temporarily buffered flow portions
(measuring mode for pulsating flow) could not
be cleared or output within 60 seconds.
Remedy:
1. Increase the setting for pulse weighting.
2. Increase the max. pulse frequency, if the
totalizer can handle a higher number of
pulses.
3. Increase or reduce flow, as applicable.
Recommendation:
– Configure the fault response of the output to
ACTUAL VALUE, so that the temporary
buffer can be cleared.
– Clear the temporary buffer by the measures
described under Item 1.
