Cause:
Current output: The actual value for the flow lies
outside the set limits.
Remedy:
1. Change the upper or lower limit setting, as
applicable.
2. Increase or reduce flow, as applicable.

Flow is Out of
Range
Cause:
Pulse output: The pulse output frequency is out of
range.
Remedy:
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.
– Variant 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
