Two kinds of setup methods, that is, digital and analog setup, are provided to set
the flow rate. Additionally, the digital setup further provides two kinds of setup
methods, single setup and multi-setup.
In single setup, the flow rate is set through key input or communications. In multi-
setup, the flow rate is set through the key input, communications, external contact
input, or external 3-way switching input. One flow set value can be set in the single
setup while up to eight flow set values can be set in the multi-setup.
In the analog setup, the flow rate is set through the external voltage/current input.
The factory setting is digital setup.
Either digital setup or analog setup is selected as the flow rate setup method (
C-03
in the function setup).
0: Digital setup (flow rate is set through the key input or communication.)
1: Analog setup (flow rate is set through the external analog voltage/current.)
For further detailed setup, make selections in
C-04
to
C-06
in the function setup.
