TOTALIZER
Calculates total based on rate and field programmable mul-
tiplier to display total in engineering units. Time base must
be selected according to the time units in which the rate is
displayed.
GRAND
TOTALIZER
ROLLOVER
Grand totalizer rolls over when display exceeds
999,999,999. Relay status reflects display.
GRAND TOTAL
ALARMS
Up to seven, user selectable under setup menu. Any set
point can be assigned to total and may be programmed
anywhere in the range of the controller for total alarm indi-
cation. Relay 1 should always be assigned to batch.
PROGRAMMA-
BLE DELAY
ON RELEASE
0.1 and 999.9 seconds; applied to the first relay assigned to
total or grand total.
If the controller is programmed to reset total to zero auto-
matically when the preset is reached, then a delay will oc-
cur before the total is reset.
GRAND TOTAL
RESET
Via front panel button, external contact closure on digital
inputs, automatically via user selectable preset value and
time delay, or through serial communications.
GRAND TOTAL
RESET PASS-

Grand total passwords may be entered to prevent resetting
the grand total from the front panel.

GRAND TOTAL
The grand total can be programmed as a non-resettable
total by entering the password “050873”.

Caution!
Once the Grand Total has been programmed
as “non-resettable” the feature cannot be
disabled.
