4.3.12 TOTALISER CONFIGURATION (Cont.)
Figure 4.3.12 Totaliser confi guration menu
Period Scaler
The totaliser equation works in seconds. If the totalised channel units are other than
‘per second’ a period scaler other than the default (1) must be entered. For example,
if the input channel is in litres per hour, then the period scaler would have to be the
number of seconds in an hour (3600).
Unit Scaler
If, for example, the input channel is in litres per hour, the totalised value will be in
litres, unless the unit scaler is set to a value other than 1. If it is more convenient, the
totalised value can be in thousands of litres by setting the unit scaler to 1000. Set-
ting the unit scaler negative causes the totaliser to decrement rather than increment.
Scale Low/High
The ‘zero’ and full scale values for the totaliser, as traced on the screen.
If A/B switching is enabled, a second set of scale low and scale high values can be
entered. ‘A’ values are used during normal operation. ‘B’ values are switched to by
job action, as described in
section 4.7
.
The remaining confi guration items are identical with the relevant items in Input Channel confi guration
(
section 4.3.3
), except that Log/Linear scale type is not available. For job information, see
section 4.7
.
Note: Selecting ‘High’ compression in
Archive confi guration
may cause very high totaliser values
to be displayed incorrectly by the recorder and held incorrectly in the history fi le. This problem
may be solved by moving the relevant point to a group using ‘Normal’ compression, or by re-scal-
ing the totaliser to read (for example) TeraWatt hours instead of Megawatt hours.
