For Dpd And Dpa Programming [6 Relay Model] - Siemens HydroRanger 200 Instruction Manual

For DPD and DPA Programming [6 relay model]

Please note that this feature is only available on the HydroRanger 200 6 relay model.
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
The points must be globally set to either 4 or 5 (as required). Point 3 becomes the
calculated value as shown above. See
Dual Point Model Use
To set a dual point HydroRanger 200 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.
