proper operation of the SENTRY 1510. A fitting accepting ¼” OD tube or pipe is provided.
 Drain Port (plugged) provides a means for connecting a drain line to the SENTRY 1510
when a vertical upward flow configuration is installed. A ¼” FNPT port with plug is provided.
 SENTRY 1510 Input Port provides a means for connecting the SENTRY 1510 to the
process exhaust output from the tool.
 Flow Direction Arrow indicates the process exhaust flow direction and points from the tool
process exhaust to the facility exhaust.

The optional CD-20 Condenser is designed to work with the SENTRY 1510 as an integrated
system. The CD-20 is designed to remove moisture from wet processing such as steam
oxidation or steam cleaning. Whenever a SENTRY 1510 will see a wet process, a BAI or OEM
comparable condenser is required. See section 5.9 for the “AVP” condenser information. Water
is the only cooling medium approved for the use with the CD-20 Condenser.
 CD-20 Input Port provides a means for connecting the CD-20 to the process exhaust output
from the tool.
 Cooling Water Input Port accepts a ¼” OD water supply line. The water does not have to
be chilled. Any flow metering device intended to control the water flow must be installed prior to
the input port.

support structure.
 Lexan Outer Wall is an enclosure that provides some impact protection to the internal
quartz tube.
 Cooling Water Outlet accepts a ¼” OD water return line. Any flow metering must not be
incorporated on the return line.
 Tie Rods secure the condenser tubes and lower mounting bracket with the upper mounting
bracket. No user serviced parts are included The tie rods must not be disconnected.
 Upper Mounting Bracket is used for mounting the CD-20 to the process tool or other
support structure.
 Connecting Rods are used to secure the SENTRY 1510 to the CD-20 to provide an
integrated pressure and moisture control system.

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.

Instruction Manual #122162 18
Guidelines
4.2 Installation Layout
The SENTRY 1510 can be ordered as horizontal of vertical installation configuration. Verify
you have the correct configuration for your installation and follow the appropriate installation
diagrams throughout this manual.

Instruction Manual #122162 19
5. Installation & Power-Up
5.1 SENTRY 1510
The SENTRY 1510 is available in a horizontally mounted configuration and a vertically
mounted configuration. Both versions will be illustrated throughout this manual. Before
beginning your installation verify the part number is the appropriate number for your
installation.
5.1.1 Mounting the SENTRY 1510 to the Process Tool
1. Selected a location for the SENTRY 1510 and mount the SENTRY 1510 Controller to the
support structure using 10-32 hardware in the threaded holes located at the base of the
unit.
Notice
Do not to over-tighten the 10-32 screws, as this could result in damage to the
internal threads.
2. For horizontal configurations be sure the 1510 Controller is within 3 degrees of horizontal.
For vertical installations be sure the unit is mounted to within 3 degrees of vertical.
3. Be sure the arrow indicating the direction of flow is pointing towards the house exhaust.

Instruction Manual #122162 20
5.1.2 Connecting the Furnace Exhaust (No BAI Condenser)
After the SENTRY 1510 is securely mounted, the process tool exhaust can be plumbed to the
input side of the SENTRY 1510. If your installation includes a BAI factory condenser please
follow the installation guidelines located in the CD-20 condenser section 4.9 of this manual.
Notice
The process exhaust should not be dampened. Fully Open ALL dampers
between the process tube and the SENTRY 1510.
1. The input of the 1510 is designed to accept 1” male NPT threads.
2. Using thread seal tape install a 1” male NPT compression or other suitable fitting into the
input side of the SENTRY 1510 controller.
3. Install a transition fitting to transition from the quartz output to 1” OD. Tubing. The transition
fitting should provide a fitting for the SENTRY 1510 process pressure sense line. The length
of the transition should not exceed 10”. Transitions that exceed this length may result in a
pressure differential preventing the SENTRY 1510 from accurately controlling the pressure
inside the process tube.
4. Using 1” OD. Tubing plumb from the Teflon transition fitting installed in step 2 to the Teflon
fitting installed at the input of the 1510 controller. If your installation is using a non BAI
condenser plumb 1” OD. Tubing from the output of the condenser to the 1” male NPT fitting
installed at the input of the SENTRY 1510.
5. For wet processing drain requirements refer to section 4.2
