3.1 Installation
I The facility exhaust line should be designed to slope down and away from
the controller to prevent any condensation that may form down stream of
the controller from backing up and collecting in the controller.
Connecting the Process Pressure Sense Tube
I - Caution: Install the process pressure sense tube prior to installing and
applying house nitrogen to the SENTRY 1510 nitrogen input port.
The SENTRY 1510 provides two gas line fittings, one on either side of the
controller body. The Swagelok fitting on the inlet side of the SENTRY 1510 is the
nitrogen fitting. The barbed fitting on the outlet side is the process pressure
(negative or positive delta pressure relative to the room reference) fitting. Plumb
the 10’ sense line to the barbed fitting.
I Ensure the Nitrogen is not plumbed to the barbed fitting used for sensing
process pressure or the SENTRY 1510 may be damaged.
