Siemens 200 P002 Material, For DPD and DPA Programming MR, Single Point Model Use

For DPD and DPA Programming [MR 200]

Please note that this feature is only available on the MultiRanger 200.

Single Point Model Use

For Dual Point Difference (DPD) or Dual Point Average (DPA), the unit requires either two transducers of the same type, or one transducer and one mA input. If two transducers are used, all transducer parameters become indexed, and a third level point is calculated.

•DPD (difference) = Point 1 - Point 2

•DPA (average) = (Point 1 + Point 2) / 2. The calculated DPD or DPA is always based

on level measurements of points 1 and 2.

For these operations any of three level points (transducer 1, transducer 2, or the calculated point) can be used to trigger relays (see P110 Level Source on page 134).

The points must be globally set to either 4 or 5 (as required). Point 3 becomes the calculated value as shown above. See Rake Control example on page 69.

Dual Point Model Use

To set a dual point MultiRanger for DPA or DPD functions, Point 3 must be set to either 4 or 5 (as required). Points 1 and 2 cannot be set to 4 or 5, but these points are used to calculate the value in point 3.

This table shows the available functions:
