Resetting the Totalizer registers clears all total data accumulated during operation.
Note: The Clear Totalizer function (CLRTOT) can only be invoked from an external
PC keyboard via the RS-232 serial port. Also invoked using digital input pins TB1-11
and TB1-12.
Commands that can be invoked from Si-Ware or HyperTerminal:
Terminal Command: CLRTOT 1
Invoking the NOTOT command disables the Totalizer. Totalization will not resume
until you repeat the F1 and numeric 2 key sequence.
Commands that can be invoked from Si-Ware or HyperTerminal:
Terminal Command: NOTOT 2 = Stop Totalizer
Terminal Command: NOTOT 2 = Starts Totalizer
The LAPTOT command freezes the Totalizer screen display. However, the flow
meter will continue to update its internal registers. The flow meter will show the
current total when you repeat the F1and numeric 3 key sequence. When you
activate LAPTOT, an L precedes the TOTAL symbol (i.e., [LTOTAL]) on the PC
HyperTerminal screen.
Clears the Batch/Sample Totalizer register. The flow meter maintains a separate
Totalizer register for Batching or Sampling applications but cannot be accessed
directly. It is used for relay control only. If you assign the system relay to this
function, a momentary (200 ms) relay pulse occurs whenever the BATCHTOT
register accumulates a specified liquid quantity. In the [Batch/Sample Tot] menu cell
the required total flow volume is entered to activate the relay. This numeric entry
must reflect the selected flow total units. The [Totalizer Scale] menu cell shows the
applicable flow total units. The sign of the Batch/Sample Total determines positive or
negative accumulation.
Clears the Makeup Latch. Refer to the Span Data menu [Set Alarms] and then the
[Makeup Latch] On / Off option.
