Menu: MONITOR / [CONTROLLER /] READINGS / TOTALIZER
D828 Totalizer 1
This read-only parameter displays the Totalizer 1 Count. To add this to the Full PV
Display, see “Display configuration options” on page 102.
Note
A Totalizer mode relay can be configured to output a pulse for each increment (by one)
to the Totalizer 1 Count parameter. See “Set-up the relays” on page 69 for information
on Totalizer mode relays
Set-up Totalizer 2
Totalizer 2 operates in the same way as Totalizer 1, but counts the parameter selected by P536.
Parameter P536 offers a choice of control unit PV, SV, TV, and FV.
Menu: SETUP / [CONTROLLER /] OUTPUT / TOTALIZER
P532 Total 2 factor (Factor default is 0.0)
One count is added to the Totalizer 2 Count (D829) for a quantity of liquid as defined by
this parameter. The units for D829 is defined by P533.
P533 Total 2 units (Factory default is "None")
This parameter defines the units for the Totalizer 2 Count (D829).
When using totalizer units of gal, an 8-digit totalizer increments rapidly and rolls over
too frequently. To help, alternative totalizer units of galx10, galx100, galx1000,
and Mgal are available for selection. When these special units are selected after
selecting gal units, the totalizer factor (P532) is automatically re-scaled by x10, x100,
x1000, or x1000000 depending on the selection. Similarly, re-scaling is automatic for
ltrx10, ltrx100, etc. after selecting ltr as totalizer units.
See “Using the App Wizard to set-up a flow application” on page 41 for a flow
application example where galx100 totalizer units are needed.
P534 Pulse Width (Factory default is 100ms)
A Totalizer mode relay is energized for a programmed duration (P534) each time the
Totalizer count (D828 or D829) is incremented. P534 controls the pulse width
(i.e. the pulse 'on' time) and is between 10 ms and 2.5 s, changeable in steps of 10 ms
Parameter P534 also defines the pulse width for a Sampler mode relay
(see “Set-up the relays” on page 69)
P536 Totalizer 2 Source (Factory default is “None”)
If requiring Totalizer 2, select a parameter to be totalized
Menu: MONITOR / [CONTROLLER /] READINGS / TOTALIZER
D829 Totalizer 2
This read-only parameter displays the Totalizer 2 Count. To add this to the Full PV
Display, see “Display configuration options” on page 102.
