INSTRUCTION MANUAL

Table 4-8. Totalizer Module

Purpose: The totalizers provide a running total of each analog input (ANI0-3). This module is
used to set input scaling factors, rollover and dropout values, and to define display tags for each
totalizer.

The value of the input is multiplied by this
parameter prior to being summed to the running
total. The parameter is used for both scaling and
time interval integration. For example, if ANI0 is in
M gallons/day, in order to totalize in K gallons the
scale factor (SF) would be:
SF = [Units Conversion] X [Time Base Conversion]
SF = [1000 K gal / M gal] X [(1 day/24 hrs) X (1
hr/60 mins) X (1 min/60 sec) X (1 sec/sample)] =
1000/86400 = 0.01157

NOTE: The time between totalizer updates is

one second.
The default value of 16666 uses the scale factor
for time interval integration. Due to the internal
timing of the instrument, a scale factor of 16666 will
cause the rollover total to occur once every minute.

Specifies the maximum value of the totalizer.
When the total reaches this value it is reset to
0.0; however totalizing continues. This value
must be a positive number.

This parameter acts like a momentary switch.
When this parameter is set to 1 the total is forced
to 0.0 and then this parameter is reset to 0.
