mA1 Failsafe
P1 and P2
P*840 mA1 Failsafe Mode
This parameter determines what happens to the mA output in the event of
the unit going into fail-safe mode. The
default
is to do the same as the
system fail-safe
(
P*808
), but this can be overridden to force the mA output
to an independent fail-safe mode as follows:
OPTION
DESCRIPTION
0 = Default
mA output will fail as per
P*808
1 = Hold
mA output will retain its last known value.
2 = Low
mA output will fail to its
low
condition.
3 = High
mA output will fail to its
high
condition.
mA1 Allocation
P1 and P2
P*841 mA1 Allocation
By default, the mA output 1 will be representative of the reading obtained,
as determined by the
Mode P*100
.
If required, mA output 1 can be configured to be representative of the
average, difference or sum of two points of measurement.
E.g., both
P*100
=
5
OCM Flow
then
mA Output1
can be configured to
give an output representative of
flow
on
point
1 or
flow
on
point 2
or the
average flow
of the
two points
or the
sum
of the
flow
for
both points.
The options available are as follows:
OPTION
DESCRIPTION
1= Point 1 (Default)
mA 1 Output relates to
Point 1
.
2= Point 2
mA 1 Output relates to
Point 2
.
3= Avg. 1 & 2
mA 1 Output relates to
average
of
Pt 1 & Pt2
.
4= Sum 1 + 2
mA 1 Output relates to
differential
of
Pt 1 & Pt2
.
5= Diff. 1
–
2
mA 1 Output relates to
sum
of
Pt 1 & Pt2
.
