6. PARAMETER DESCRIPTION

(5) Menu F: Status Functions Setting items

Menu F contains setting items relevant to status Input/Output functions.

[F10: SO1 Function] Setting of the function for the SO1 status output terminal This parameter sets the function for the SO1 (status output 1) terminal.

Setting	Function	Description
No Function	Stop output (i.e., inactive condition)	As no function is set, there is no output.
Warning Output	Output upon warning	Refer to Alarms (Section 6.5)
		Status output is carried out when the forward internal
Total Switch	Totalization switch output	totalized value reaches or exceeds the totalization switch value.
		The totalization switch value is determined using D23: Ttl
		Switch Lower and D24: Ttl Switch Upper.
		Status output is carried out when the instantaneous flow rate
H/L Alarm	H/L alarm output	equals or falls below the low flow rate limit (L), or when it equals
		or exceeds the high flow rate limit (H). These limit values are
		determined using G10: Low Alarm and G11: High Alarm.
		Status output is carried out when the instantaneous flow rate
		equals or falls below the low-low flow rate limit (LL), or when it
HH/LL Alarm	HH/LL alarm output	equals or exceeds the high-high flow rate limit (HH). These limit
		values are determined using G12: Low Low Alarm and G13:
		High-High Alarm. To output “HH/LL Alarm” as an alarm, set
		G33: Alm-HH/LL to “Yes”.
		When flow is in the reverse direction, switching to the reverse
Fwd/Rev Ranges	Forward/reverse flow rate measurement	range is carried out automatically, measurement is performed,
		and status output is carried out.
Auto 2 Ranges	Automatic 2 ranges switching	This function ensures that when the instantaneous flow rate
		exceeds 100% of the range, transition to the next range is
Auto 3 Ranges	Automatic 3 ranges switching (Note 1)
		carried out automatically. Status output is carried out
Auto 4 Ranges	Automatic 4 ranges switching (Note 1)
		upon range switching.
Ext 2 Answer	Answerback: 2 ranges switching via
	external status input
		When range switching is carried out in response to external
Ext 3 Answer	Answerback: 3 ranges switching via
		status input, status output is performed in the form of an
	external status input (Note 1)
		answerback to indicate the range currently being used.
Ext 4 Answer	Answerback: 4 ranges switching via
	external status input (Note 1)

Note 1: When these functions are selected, two terminals become necessary for status output.

Accordingly, the setting for F10: SO1 Function is automatically adopted as the setting for F11: SO2 Function.

(Setting of these functions is not possible using F11: SO2 Function.)

Note 2: Function-specific SO1 and SO2 operations

Operations are performed in accordance with the content of 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" using this parameter.

T0623.EPS

Selected function	Condition of SO1 or SO2 terminal
	Open (Off)	Closed (On)
Warning Output	Good (normal)	Warning status
Total Switch	Below setting value	Equal or above setting value
H/L Alarm	Normal	H/L alarm status
HH/LL Alarm	Normal	HH/LL alarm status
Fwd/Rev Ranges	Forward direction	Reverse direction

Note: For “Auto 2 Ranges,” “Auto 3 Ranges,” “Auto 4 Ranges,” “Ext 2 Answer,” “Ext 3 Answer,” and “Ext 4 Answer,” see the Multiple ranges setting section.

T0624.EPS

[F11: SO2 Function] Setting of function for the SO2 status output terminal

This parameter sets the function for the SO2 (status output 2) terminal. Selectable functions are the same as for F10: SO1 Function; however, the selection of “Auto 3 Ranges”, “Auto 4 Ranges”, “Ext 3 Answer”, or “Ext 4 Answer” is not possible for F11.
