Total decimal point is independent of
rate decimal point.
Totalizer
Calculates total based on rate and
field programmable multiplier 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 grand total and may be
programmed anywhere in the range
of the controller for grand total alarm
indication. Relay 1 should always be
assigned to batch.
Programmabl
e 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 automatically when
the preset is reached, then a delay
will occur 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
Password
Grand total passwords may be
entered to prevent resetting the
grand total from the front panel.
Non-
Resettable
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

cannot
be
disabled.

Note: Relay coil is energized in non-
alarm condition. In case of
power failure, relay will go to
alarm state.
Alarm Auto
Initialization
When power is applied to the
controller, relays will reflect the
state of the input to the controller.
