APC AXFA11G B41/H11 Display Select2 and B42/H12 Display, Menu C Basic Setting items, No Execution

B41/H11: Display Select2 and B42/H12: Display

Select3 as described below. (For more details, refer to Chapter 5: Basic Operating Procedures.)

CAUTION

It is not possible to set Display Select1 to “Off”.

[B41: Display Select2] Setting of the second line for display unit

→This setting is linked with that of parameter H11. This parameter selects the display content of the second line for display unit. When “Off” is selected, one-line display will be adopted regardless of the setting made for B42/H12: Display Select 3.

[B42: Display Select3] Setting of the third line for display unit.

→This setting is linked with that of parameter H12. This parameter selects the display content of the third line for display unit. When “Off” is selected for this parameter, two-line display is adopted.

[B50: Auto Zero Exe] Execution of the automatic zero adjustment function

→This setting is linked with that of parameter M10. This parameter executes the automatic zero adjustment function: If “Execution” is selected, this function will be started. “Now Auto Zero Executing...” is indicated while the Auto Zero function is being carried out. The result of the automatic zero adjustment is confirmed using M11: Magflow Zero, and if the result exceeds the rated value, the warning 82: Auto Zero Wng will be displayed. (For more details, refer to Chapter 9: Operation.)

Setting	Function
No Execution	No execution
Execution	Automatic zero adjustment is started.

6. PARAMETER DESCRIPTION

will be setup upon shipment from the manufac- turing plant, and these will not require additional setting. If the AXFA11 is ordered individually, the default value will be setup for the meter factor; accordingly, it will be necessary to set the meter factor indicated on your remote flowtube data plate.

If a flow rate span is specified upon ordering, this will be set before shipment. If this is not the case, however, it will be necessary for the appropriate value to be set up by the user.

[C10: Tag No] Setting of the tag number

→The setting for this parameter corresponds to one of the ordered items.

Up to a maximum of 16 characters can be entered for the display unit. For more details regarding the actual characters that can be used, refer to Section 5.2.2:

Setting Mode.

NOTE

If a tag number is specified upon ordering, this parameter is set up before shipment; however, if this is not the case, it will be necessary for the appropriate value to be set up by the user.

[C11: Flow Damping] Setting of the damping time

→Refer to the description of parameter B20.

[C20: Measure Mode] Selection of dual frequency excitation mode

Item	Description
Standard DF	Standard dual frequency excitation
Enhanced DF	Enhanced dual frequency excitation

(2) Menu C: Basic Setting items

Menu C principally contains the basic setting items for the flowtube.

NOTE

In order to ensure that correct flow rate data can be acquired, it is crucial that the nominal size, flow rate span, and meter factor of the combined remote flowtube are setup. In cases where a remote flowtube is ordered at the same time as the AXFA11, the nominal size and meter factor

Enhanced DF (i.e., enhanced dual frequency excitation) is set to stabilize measurement for difficult applica- tions, such as for high concentration slurries or low conductivity fluid. Note that this parameter is only valid when this product is used in combination with an AXF flowtube, as only supports enhanced dual frequency excitation. (Optional code HF1 or HF2)

NOTE

•When this product is used in combination with any flowtube that does not support enhanced dual frequency excitation and “Enhanced DF” is
