PC, PC3, PCR and PCD Series Pressure Controller Operation
All PC, PC3, PCR and PCD Series Controllers have a default Main Mode, a Select Menu Mode, a
Control Setup Mode, a Communication Select Mode, a Manufacturer Data Mode and a Miscellaneous
Mode. The device defaults to Main Mode as soon as power is applied to the controller.
PC Series Pressure Controllers are normally shipped with a 0.050” diameter valve orifice which permits
flows up to 20 SLPM (with inlet pressure 20 PSI over controlled pressure). For much smaller flows,
consult factory for details on specifying a smaller valve orifice. For larger flows, a PCR Series Pressure
Controller is recommended.
For additional information specific to the PCD series (dual valve
controllers) see page 22.

below.)
Flashing Error Message:
Our pressure gauges and controllers display an error message (POV =
pressure overrange) when the pressure exceeds the range of the sensors in the device. When the
pressure reading flashes on the display, the pressure measurement is not accurate. Reducing the value
of the line pressure to within specified limits will return the unit to normal operation.
Select Menu Mode
Pushing “Mode” once will bring up the “Select Menu” display (Figure 13, page 17). Push the button
nearest your selection to go to the corresponding screen. Push “Mode” again to return to the Main
Mode display.
