4.3.20 Atmospheric-Pressure Balancing Valve ON/OFF
Setting
To set the On/Off time of atmospheric-pressure balancing valves, select the Atmospheric-
Pressure Balancing Valve command from the Setup menu. The Atmospheric-Pressure Balancing
Valve ON/OFF Setting dialog box appears.
Figure 4.27 Atmospheric-Pressure Balancing Valve Setting dialog box
If atmospheric-pressure balancing valve is not used for the active GCM, the Atmospheric-
Pressure Balancing Valve command is grayed out on the Setup menu and you cannot select it.
In this dialog box, you can change the ON and OFF time for each method number of the
atmospheric-pressure balancing valve of the specified system number.
First, select a system number, method number, and valve number. Three pairs of ON and OFF
times of the valve are displayed. Change the ON and OFF times and click the Change button.
A confirmation message asking “Are you sure you want to send the data?” is displayed in the
message box. When you respond with “Yes”, the settings are changed.
Each item can be selected in the following range.
System number: A number belonging to the current GCM
Method number: 1 to 6
ATM number: The atmospheric-pressure balancing valve number of the GCM is displayed. This
cannot be selected.
Valve ON time: “- Preparation time to System analysis cycle - 2 sec”
Valve OFF time: “ON time to System analysis cycle - 2 sec”
However, if it is set to “********”, both ON and OFF times are made invalid.
