351
to
354 S: CURRENT RANGE n
$
: # 351…354
Current output:
The actual value for the flow lies outside the set limits. 1. Change the upper or lower limit setting, as applicable.
2. Increase or reduce flow, as applicable.
355
to
358 S: FREQ. RANGE n
!: # 355 to 358 Frequency output:
The actual value for the flow lies outside the set limits. 1. Change the upper or lower limit setting, as applicable.
2. Increase or reduce flow, as applicable.
359
to
362 S: PULSE RANGE
$
: # 359…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
3. Reduce flow.
379
to
380 S: FREQ. LIM
$
: # 379…380
The measuring tube oscillation frequency is outside the
permitted range.
Causes:
– Change the upper or lower limit setting, as applicable.
– Increase or reduce flow, as applicable.
