Allocation
P1 and P2
P*899 mA2 Allocation
By default the mA output 1 will be representative of the reading obtained, as
determined by the Mode P2-100.
If required, mA output 2 can be configured to be representative of the
average, difference or sum of two points of measurement.
E.g. Both P1-100 and P2-100 = 6 Volume then mA Output 2 can be
configured to give an output representative of volume on point 1 or
volume on point 2 or the average volume of the two points or the sum of
the volume for both points.
The options available are as follows:
mA 1 Output relates to Point 1.
mA 1 Output relates to Point 2.
mA 1 Output relates to average of Pt 1 & Pt2.
mA 1 Output relates to differential of Pt 1 & Pt2.
mA 1 Output relates to sum of Pt 1 & Pt2.
Important Information
When mA Output 1 is to be representative of the average or sum of two points
of measurement, then both points must be set to the same units of
measurement. In the case of flow P1-100 and P2-100 are set for 4 (OCM Head)
or 5 (OCM Flow), then P1-706, P2-706 (Volume Units) & P1-707, P2-707
(Time Units) must be the same. And in the case of Volume then P1-100 and
P2-100 are set for 6 (Volume) then P1- 605, P2-605 (Volume Units) must be
the same.
Important Information
When both mA Output 1 and mA Output 2 are allocated to the same point of
measurement, in order for them to output the same reading, both of the mA low
value (P834/P892) and mA high value (P835/P893) must be the same for each
mA Output.
