4. Guidelines
4.1 Installation Guidelines
Before beginning the design and installation lay out, consider the following general installation
features, guidelines and limitations.
1. The SENTRY 1510 controller must remain free of all moisture. For installation on wet
process a condenser must be installed in the exhaust path prior to the SENTRY 1510.
2. The SENTRY 1510 is equipped with four 10-32 threaded mounting holes located at the base
of the unit. These four holes should be used for mounting the SENTRY 1510 to the process
tool. Use caution not to over tighten mounting hardware.
3. An arrow in the Teflon portion of the SENTRY 1510 indicates the direction of flow. The
arrowhead must point towards house exhaust.
4. The SENTRY 1510 should be mounted in an accessible location on or in close proximity of
the process tool.
5. The process sense tube is shipped in a 10-foot length. Any extra length should be loosely
coiled.
Care should be taken to avoid pinching or blocking of the sense
line as damage to the SENTRY 1510 Transducer may occur.
6. Mounting configuration:
(a) Horizontal configured SENTRY 1510’s must be installed within 3 degrees of level in the
horizontal plane.
(b) Vertical configured SENTRY 1510’s must be installed within 3 degrees of level in the
vertical plane.
7. To maintain CE certification, if applicable, the Tool Interface Module must be installed at a
height above the floor greater than 24” (0.6 meter).
8. The Tool Interface Module requires that the analog ground and the power ground be
common on the tool side (refer to page 24 and Appendix C).
9. The minimum static exhaust required for proper operation of the SENTRY 1510 at least 10
mm H2O more negative than set point (vary by installation).
10. The SENTRY 1510 requires an input of house grade or better Nitrogen regulated to 40 - 100
PSI.
