Chapter 1. INTRODUCTION
• Automatic shut-off function
The valve can be shut off automatically under the following conditions:
• When the integration count value reaches the setting value.
• When one of the alarms, including flowrate alarms, occurs.
However, the valve of this device does not have a capability of complete shut-
off. When the complete shut-off is required, provide a separate shut-off valve
externally.
• Automatic reset of integration count at start of control function
Start of control and integration count reset can be carried out simultaneously
by a single action (key operation or external switching input). Combining this
function with the automatic shut-off function described above is handy for
shutting the valve off when a fixed number of integration values have been
counted repeatedly.
• Direct setup function
This function allows users to easily change the flowrate setup.
This function is useful when you frequently change setting values, for example,
when you adjust the preset flowrate during trial operation.
• Loader communication function
Connecting a loader cable (sold separately) to the loader jack at the rear side of
this device enables direct communication with a personal computer in the form
of one to one using the communication program made by user. By using this
loader communication, various settings in the function setup and the flowrate
setup can be configured from a personal computer, and the control flowrate or
alarm status can be read out with the personal computer.
