P071 FAILSAFE MATERIAL LEVEL
Select the material level to be reported when the Failsafe Timer expires.
If
"HOLd"
(preset) is selected, the "last known" material level is held.
If
"HI"
is selected, the HYDRO+ advances to the Span (P007) level, per
Failsafe Level Advance (P072).
If
"LO"
is selected, the HYDRO+ advances to the Empty (P006) level,
per Failsafe Level Advance (P072).
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 HI alarm relay, select "HI" (if P129 = "OFF").
e.g. 2) To force a low mA output, select "LO" (if P219 = "OFF").
Ensure relays and mA outputs used for Failsafe Operation
are wired and programmed appropriately.
To select HI, LO, or HOLd...
to display the Auxiliary Function symbol,
or as required to scroll access the desired option,
Alternatively, enter a specific Failsafe Material Level within -50 to 150%
of Span (P007), in Units (P005), or % of Span.
values: -999 to 9999
P072 FAILSAFE LEVEL ADVANCE
Select the method for the HYDRO+ advance to (and from) the
Failsafe Material Level.
When "restricted" (preset), the HYDRO+ advances to/from the Failsafe
Material Level, as determined by 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.
When "fast back" is selected, the Failsafe Level Advance is restricted,
however the advance to the new material level is immediate.
values: 1 = restricted
2 = immediate
3 = fast back
