[F15: SI1/2 Active Mode] Setting of the active mode for status input
This parameter sets the active mode for the terminals SI1 and SI2. Active modes cannot be set individually for these two terminals.
Setting | Function | |
|
| |
Short Active | When the status input is set to "Short", occurrence | |
of the selected event will be recognized. | ||
| ||
Open Active | When the status input is set to "Open", occurrence | |
of the selected event will be recognized. | ||

NOTE
Multiple ranges setting
Parameters from F30 to F41 are used with the automatic multiple ranges and the multiple ranges switching via external status input. The followings will describe the setting method for each range.
The multiple ranges use the following parameters:
[B23: Flow Span ] Setting of the flow rate span (Setting of the forward No.1 range)
[F30: Forward Span 2] Setting of the forward No. 2 range
[F31: Forward Span 3] Setting of the forward No. 3 range
[F32: Forward Span 4] Setting of the forward No. 4 range
[F33: Reverse Span 1] Setting of the reverse No. 1 range
[F34: Reverse Span 2] Setting of the reverse No. 2 range
[F35: Reverse Span 3] Setting of the reverse No. 3 range
[F36: Reverse Span 4] Setting of the reverse No. 4 range
6. PARAMETER DESCRIPTION
[F40: Auto Range Hys] Setting of the automatic multiple range hysteresis width
[F41: Bi Direction Hys] Setting of the forward/ reverse flow measurement hysteresis width
Multiple Ranges Setting 1:
Automatic multiple ranges switching
When the instantaneous flow rate exceeds 100% of the range, transition to the next range (up to four ranges) is carried out automatically. Furthermore, when the flow is in reverse, the reverse range can also be automatically selected.
Range switching can be confirmed according to the status of the SO1 and SO2 status output terminals. Refer to Table 6.4.1: Status Output for Automatic Multiple Ranges Switching for details of status output conditions for each range.
Status Output for Automatic Multiple Ranges Switching
Operations are performed in accordance with the following table when the active mode has been set to “Closed (On) Act” using F14: SO1/2 Active Mode. Operating patterns are reversed when the active mode has been set to “Open (Off) Act”.

*: "No Function" is the default value. Only SO1 or SO2 terminals are used for single or dual ranges; accordingly, the unused terminal remains at the default value (i.e., No Function) and can therefore be used for other functions.
