Getting to Know Your Pressure Controller
The Pressure Controller Display
The figure below identifies the various features of the main pressure controller display.
Highlights pressure in the center of the display.
Tares the pressure (typically unavailable for abso-
lute pressure devices) (page 11).
Opens a menu to set the pressure control setpoint (page 12).
Enters the main menu system (page 11).
Toggles the backlight (more display options are on page 19).
✓
Note: Buttons 4 and 5 have no functions on the main display for pressure devices.
Status Messages
Status messages are shown to the right of the main readout number. In the example to
the right the LCK message indicates that the front display is locked.
ADC Analog-digital converter error
LCK Front display is locked
POV Pressure over range of device
Mounting
Pressure controllers do not require straight runs of pipe upstream or downstream. Most
pressure controllers can be mounted in any position, including upside-down. Corrosive-re-
sistant pressure controllers use media-isolated sensors that must be tared after changing
their orientation.
▲
Caution: Pressure controllers that use large Rolamite valves (PCR, PCR3, PCRS) should
be mounted with their valve oriented vertically (right-side up). Please contact support
for other orientations.
Filters
When pressure drop is not a concern, use in-line sintered filters to prevent large particulates
from entering the pressure controller. Suggested maximum particulate sizes are as follows:
• 20 microns for PC, PCP, PCH, PC3
• 40 microns for PCR, PCR3

button (7), which toggles the
device backlight.

information, and a LCK status.
