5.6.1 Bank automatic switching setting
■ The operation procedure of bank automatic switching is explained below.
Switching conditions are set in the SET 23 parameter. The bank switching method (input, switching
sensitivity, etc.) and switching threshold are set.
Parameters desiring to be switched are set for each threshold in the SET 20 bank setting.
For details of the bank setting method, see Section 5.4.4 Bank function (P5-28 to 30).
The diagram below shows the procedure of the SET 23 parameter setting. Follow the procedure for
setting.
[Setting flow]
SET 23 (ZbNK)
Setting the bank automatic
switching function setting mode
Setting bank automatic switching
When SET 04 bANKH  0, bank automatic switching is ineffective.
No parameter of SET 23 is displayed.
When bANKH = 0:
SET 23 returns to
the beginning.
When bANKH  0:
SET 23 (bAF)
Selecting the bank automatic
switching function
Setting the bank automatic switching function selection *1
I. When bAF  0, the bank automatic switching run OFF
II. When bAF  1, the bank automatic switching run ON
II.
When bAS = 1

When bAF = 0:
SET 23 returns to
the beginning.
SET 23 (bAS)
Setting the bank automatic
switching source
Bank automatic switching source setting *2
III. When bAS  0 (SV value)
When bAS  1 (ramp SV value)
When bAS  2 (PV value)

When bAS = 0, 1, or 2:
SET 23 (PM*)
Setting the zone threshold*
Zone threshold* setting *3
IV. PM* (“*”  1 to 7 repetitive setting)

When bAS = 2:
III.
When bAS = 0:
SET 02 (LR)
Setting the remote/local switching
Follow the status of the remote/local switching setting value.
< When LR  0, ASC setting: Existent; when LR  1 or 2, ASC
setting: Nonexistent >
* This screen is not displayed in the SET 23 setting sequence.
The setting should be made with SET 02 beforehand.
VI.
When LR = 1 or 2:
V.
When LR = 0:
SET 23 (ASC)
Setting the zone threshold
switching sensitivity range
Zone threshold switching sensitivity range setting *4
VII. ASC = 0.0 to 999.9
III.
When bAS = 1:
SET 23 returns to the beginning.
Note The automatic switching is ineffective if [SET 04 bANKH  0].
In addition, be careful that the SET 23 parameter is not displayed.
Note The parameters of [bAS] and thereafter are not displayed if [bAF  0].
The parameter contents of SET 23 are explained in the next page.
