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 material level is
held.
If "HI" or "LO" are selected, the XPL Plus 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 (perhaps to stop material
infeed), select "HI".
e.g. 2 To force an "empty vessel" mA output (perhaps to have
pumps stopped), select "LO".
To select HI, LO, or HOLd:
Press to display the Auxiliary Function symbol.
Press or as required to scroll access the desired option.
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 XPL Plus advance to (and from) the Failsafe
Material Level.
When "restricted" (preset), the XPL Plus advances to the Failsafe Material Level
(and to the "new" material level when a valid measurement is made) as
determined by the Measurement Response (P003) or the Max Fill / Empty Rate
(P700 / P701) values entered.
Alternatively, when "immediate" is selected, the Failsafe Material Level (or "new"
material level) is assumed immediately.
Otherwise, when "fastback" 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 = fastback
