6. PARAMETER DESCRIPTION

[D20: Total Execution] Operation setting for the

totalization function

totalized value.

*: The preset function starts the count for totalization

from the set value.

Item Description

Start (initial value)

Stop

Preset Total

Preset Rev Total

Starts totalization

Stop totalization

Sets the preset value for totalization display that has

been specified as the forward totalized value. Preset

value are determined using D21: Ttl Set Val Lower

and D22: Ttl Set Val Upper.

In case that “Start” is sellected, the count for

totalization starts from the preset value. Setting of zero

as the preset value allows the zero-reset function to be

implemented.

Sets the preset value for totalization display that has

been specified as the reverse totalized value. Preset

value are determined using D21: Ttl Set Val Lower

and D22: Ttl Set Val Upper.

In case that “Start” is sellected, the count for

totalization starts from the preset value. Setting of zero

as the preset value allows the zero-reset function to be

implemented.

NOTE

Totalization presets can also be set up by using

status input. For details regarding the setting

method, refer to the descriptions of F12 and

F13.

[D21: Ttl Set Val Lower] Setting of the totalization

preset value (lower 6 digits)

This parameter sets a totalization preset value in the

lower 6 digits of the 8-digit totalized value. If zero is

to be set as the preset value, “000000” should be set

here.

[D22: Ttl Set Val Upper] Setting of the totalization

preset value (upper 2 digits)

This parameter sets a totalization preset value in the

upper 2 digits of the 8-digit totalized value. If zero is

to be set as the preset value, “00” should be set here.

Upper 2 digits

Lower 6 digits

[D23: Ttl Switch Lower] Setting of the totalization

switch value (lower 6 digits)

The totalization switch function operates to set the

status output terminal (i.e., SO1 or SO2) to “Closed

(On)” when the forward internal totalized value reaches

or exceeds the totalization switch value. (For details

regarding the setting method for the status output, refer

to the descriptions of parameters F10 and F11.)

If this function is set up, the totalization count will stop

at 99999999.

D23 sets the lower 6 digits of the 8-digit totalization

switch value.

[D24: Ttl Switch Upper] Setting of the totalization

switch value (upper 2 digits)

This parameter sets the upper 2 digits of the 8-digit

totalization switch value.

[D30: Ttl User Select] Selection of the use of

special totalization unit

This parameter specifies whether or not special units

are used for totalized units. Actual setting of these

units is carried out using D31: Ttl User Unit.

[D31: Ttl User Unit] Setting of special totalization

units

Units of up to maximum 8 characters in length can be

specified using this parameter. The units set with this

parameter are displayed whenever totalization (i.e.,

FTL, RTL, DTL) is selected in the Display Mode, and

they are displayed for A30: TOTAL, A31: REV

TOTAL, and A32: DIF TOTAL when BRAIN

communication is being carried out.

NOTE

Example: To count in 1 dl (deci-liter) steps

with flow rate span=10 l/s.

Since 1 dl (deci-liter) = 0.1 l (liter),

“l (Liter)” is set for B21/C40: Base

Flow Unit,

“/s” is set for B22/C41: Base Time

Unit,

“10” is set for B23/C42: Flow

Span,

“Unit/P” is set for B30/D10: Total

Unit,

“0.1” is set for B31/D11: Total

Scale,

“Yes” is set for D30: Ttl User

Select,

1 2 ... 41 42 43 44 45 46 47 48 49 50 51 ... 117 118
