ADVANCED CONFIGURATION LEVEL…
Cut-off Level
Set the lowest value at which the totalizer is to stop counting (in engineering units).
Example – On differential pressure flow, the inaccuracy of the system at very low flow rates may
cause large accumulative totalizer errors due to erroneous counts. If a cut-off level is set above
the point where these erroneous counts occur they are ignored.
Preset Value
If the
OPERATOR LEVEL
(batch) flow total is reset it reverts to the value set at this frame.
Set the value for the first digit using the
/
switches. The value is changed by using the
switch to advance the flashing cursor (
_
) and altering each digit in turn.
Advance to next digit.
/
Set the value for the second digit.
Advance to next digit.
Repeat the above procedure for the remaining digits.
Note. The setting of the
Preset
and
Predetermined Values
is dictated by the
Count Direction
:
CNtdIr-UP
(incremental counter) –
Preset Value
<
Predetermined Value
CNtdIr-dN
(decremental counter) –
Preset Value
>
Predetermined Value
.
Predetermined Value
If the wrap-around facility is used (see below), the front panel total is automatically reset to the
Preset Value
once the
Predetermined Value
is reached. If the wrap-around facility is not used, the
front panel total stops when the
Predetermined Value
is reached.
Set the value for the first digit using the
/
switches. The value is changed by using the
switch to advance the flashing cursor (
_
) and altering each digit in turn.
Advance to next digit.
/
Set the value for the second digit.
Advance to next digit.
Repeat the above procedure for the remaining digits.
