APC AXFA11G user manual Description

Example 1: To count in 1 Ml (mega-liter) steps with flow rate span = 100 m3/h Since 1 Ml = 103 x m3, k Unit/P is set for B30/D10, and 1 is set for B31/D11. “x103 m3” is indicated for the totalized units in the Display Mode.

Example 2: To count in 10 l (liter) steps with flow rate span = 100 m3/h Since 1 l = 10-3x m3, m Unit/P is set for B30/D10, and 10 is set for B31/D11. “x10-2m3” is indicated for the totalized units in the Display Mode.

Example 3: To count in 5 l (liter) steps with flow rate span = 100 m3/h Since 1 l = 10-3x m3, m Unit/P is set for B30/D10, and 5 is set for B31/D11. Since B31/D11 is not 0.001, 0.01, 0.1, 1, 10, 100, or 1000, there is no indication of totalized units in the Display Mode.

•Setting of totalization scale is not possible when specific selections have been made for B30/D10: Total Unit, B31/D11: Total Scale, and B23/C42: Flow Span. In such a case, a setting alarm will be displayed, and parameters should be changed in accordance with the instructions given.

[B32: Pulse Unit] Setting of the pulse units

→This setting is linked with that of parameter E10.

This parameter selects the flow rate units to be used for pulse output.

[B33: Pulse Scale] Setting of pulse scale

→This setting is linked with that of parameter E11. Pulse output is performed in individual counts in accordance with this parameter’s setting. If 0 is selected, it indicates that the pulse output function is not to be used.

6. PARAMETER DESCRIPTION

NOTE

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

NOTE

•By setting the pulse scale, pulse output per- forms. The pulse scale is determined in accor- dance with the settings of B32/E10: Pulse Unit and B33/E11: Pulse Scale.

•If multiple ranges are being used, the flow rate span for the smallest range becomes the standard for the E13: Pulse Low Cut setting value.

•Pulse output for the reverse flow rate is carried out only when “Fwd/Rev Ranges” is selected for F10: SO1 Function or F11: SO2 Function.

•Setting of pulse scale is not possible when specific selections have been made for B32/ E10: Pulse Unit, B33/E11: Pulse Scale, E12: Pulse Width and B23/C42: Flow Span. In such a case, a setting alarm will be displayed, and parameters should be changed in accor- dance with the instructions given.

Example 1: To perform pulse output in 1 Ml (mega-liter) steps with flow rate span = 100 m3/h

Since 1 Ml = 103 x m3, M Unit/P is set for B32/E10, and 1 is set for B33/E11.

Example 2: To perform pulse output in 10 l (liter) steps with flow rate span = 100 m3/h

Since 1 l = 10-3x m3, m Unit/P is set for B32/E10, and 10 is set for B33/E11.

Example 3: To perform pulse output in 5 l (liter) steps with flow rate span = 100 m3/h

Since 1 l = 10-3x m3, m Unit/P is set for B32/E10, and 5 is set for B33/E11.

[B40: Display Select1] Setting of the first line for display unit

→This setting is linked with that of parameter H10. This parameter selects the display content of the first line for display unit. The size of the characters which are displayed will depend on the selections made for
