P071 Failsafe Material Level
Select the material level to be reported when the Failsafe Timer expires.
If
“HOLd”
(preset) is selected, in the RUN mode, the “last known” sludge level is
held.
If
“HIGH”
or
“LOW”
are selected, the DPS300 advances to the Span (P007) level
or Empty (P006) level as restricted by Failsafe Level Advance.
Select the Failsafe Material Level based upon the relay and/or mA output
operation required during failsafe operation.
e.g.1 To de-energize a high alarm relay select “HIGH”.
e.g.2 To force an “empty level” mA output (perhaps to have pumps stopped),
select “LOW”.
To select HIGH, LOW, or HOLd...
1. Press to display the Auxiliary Function symbol,
2. Press or as required to scroll access the desired option,
3. Press .
Alternatively, a specific Failsafe Material Level within -50 to 150% of Span (P007)
may be entered directly in Units (P005), or % of Span (P007).
Values
:
-999 to 9999
P072 Failsafe Level Advance
Select the restriction applied to the DPS300 advance to (and from) the Failsafe
Material Level.
When “restricted” (preset), the DPS300 advances to the Failsafe Material Level
(and to the “new” material level when a valid measurement is made) at the Max
Fill/Empty Rate (P700/P701) to a maximum of 0.1 m/min
Alternatively, when “immediate” is selected, the Failsafe Material Level (or “new”
material level) is assumed immediately.
Otherwise, when “fast back” is selected, the Failsafe Level Advance is restricted,
however the advance to the new material level (when a valid measurement is
made) is immediate.
Values:
1 = restricted
2 = immediate
3 = fast back
