[Operation]
Process Data OUT
• Setting active state (pressure controlled state)
Set the "Start/Stop" bit of the Process Data OUT to "1" to
create an active state. Control is performed at the
pressure stored in the preset memory corresponding to
the preset memory number.
• Switching preset memory
The preset memory number can be switched according
to the "Preset" setting of the Process Data OUT. Entering
the 3 bits of the "Preset" according to the right table
allows you to switch to any of the set pressures stored in
the memory areas.
[Confirmation]
Process Data IN
The controlled pressure, start/stop status, input setting, and set pressure can be checked with the
Process Data IN.
Check the current set pressure with the "Set Value for pressure" in Process Data IN.
• When the "Start/Stop" bit of the Process Data IN is set to "0" (Stop) and the "Input setting" is
not set to "1" (Preset Mode), the pressure is not controlled even after the "Preset" bit of the
Process Data OUT is switched.
