The temporarily buffered flow
portions (measuring mode for
pulsating flow) could not be cleared
or output within 60 seconds.
1. Change the upper or lower limit setting, as
applicable.
2. 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.

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.

!: # 359 to 362
Pulse output:
Pulse output frequency is out of
range.
1. Increase the setting for pulse weighting.
2. When selecting the pulse width, choose a value
that can still be processed by a connected
counter (e.g. mechanical counter, PLC etc.).
Determine the pulse width:
– Version 1: Enter the minimum duration that a
pulse must be present at the connected
counter to ensure its registration.
– Version 2: Enter the maximum (pulse)
frequency as the half "reciprocal value" that a
pulse must be present at the connected
counter to ensure its registration.
Example: The maximum input frequency of the
connected counter is 10 Hz.
The pulse width to be entered is:
A0004437
