 Automated SENTRY 1000 The Automated SENTRY 1000 is an innovative
process exhaust controller. It is a pressure regulator designed to respond almost
instantaneously to changes in static exhaust pressure. This maintains a constant
exhaust condition at the process tool.
 Booster Fan (Optional) The booster fan is an integrated point-of-use fan
that provides increased static exhaust to the SENTRY 1000. This option is
typically chosen for installations with low facility static exhaust pressure.
 Viewing Window The viewing window allows the user to determine if the
piston is operating or if cleaning is required.
 SENTRY 1000 Input The input provides a means for connecting to the
process exhaust output.
 Throttle The throttle is commanded by the TIM-100/120 when a set point
change is made. The throttle modulates the pressure regulation of the piston. It
typically is not used for active pressure regulation.
 Pressure Transducer The pressure transducer measures the process
exhaust differential pressure and reports the value to the TIM-100/120.
 Canister The canister is the enclosure inside which the piston operates.
 SENTRY 1000 Output The output provides a means for connecting to the
facility exhaust hook up.

 Piston Reference Port The piston reference port senses the ambient static
pressure of the process tool environment controlled by the SENTRY 1000. It
also provides a piston air-bearing which is critical to the proper operation of the
SENTRY 1000.
 Support Base (Support Legs)
The support base is used to mount the
 Piston The piston is the single
controlling component. It provides a
continuous mechanical pressure
regulation. The piston mechanically
responds to changes in facility exhaust
to maintain a stable process exhaust.
 Cylinder The cylinder supports
the piston during operation. The
piston moves vertically up and down
along the cylinder. The design of the
product allows the space between the
cylinder and the piston to be
frictionless through the use of an air-
bearing.

a full 360.
3) The use of a reference tube is typically not required. However, in the event
that a reference tube is required, the maximum length for a reference tube is
8 feet (2.4 meters). Prior to configuring an installation layout, determine if
the use of a reference tube may be required according to the matrix/chart
depicted on page 23.
4) To maintain CE certification, if applicable, the TIM-100/120 must be installed
at a height above the floor greater than 24” (0.6 meter).
5) A recommended grounding scheme for the SENTRY 1000 and TIM-100/120
is depicted in Appendix C on page 50. Both the SENTRY 1000 and the TIM-
100/120 should be grounded as indicated.
6) The minimum static exhaust required at the SENTRY 1000 output (without
integrated booster fan) is -2.5” H2O (-64 mm H2O) at rated capacity.

3.6 Installation Layout
Design an installation layout and mounting strategy for the SENTRY 1000, TIM-
100/120, process pressure sense line, reference tube, cables and grounding
connections. Refer to the appropriate dimensional prints of the system
components in the drawings section at the end of this manual.
Choose a location for mounting the SENTRY 1000 controller. This should be in a
level, secure and accessible location. To allow for easier installation and
maintenance access, ensure clearance space is available, depending on model,
below or to the side of the SENTRY 1000.
 Allow 6” (150 mm) of clearance below the 60 CFM SENTRY 1000 model.
 Allow clearance to the side of the 100 and 130 CFM SENTRY 1000
models. This must be to the side of the canister which is not obstructed
by the support legs.
Notice
• Allow 8” (200 mm) of clearance for the 100 CFM SENTRY 1000 model.
• Allow 10” (250 mm) of clearance to the side of the 130 CFM SENTRY 1000
model.
• Ensure clearance specified on the 100 and 130 CFM models on both sides of
the SENTRY 1000 valve opposite the support legs.
 Ensure that the support structure allows for the SENTRY 1000 to be
mounted within 0.5 of level.

3.7 Installation - Sentry 1000
Align the SENTRY 1000 Output
The bottom port of the SENTRY 1000 is the output and must be plumbed to the
facility exhaust. Align the SENTRY 1000 output port facing towards the facility
exhaust connection.
Mount the SENTRY 1000
Having selected a location for the SENTRY 1000, mount the SENTRY 1000 to
the support structure using the bolt holes located on the support base.
 The bolt holes are located towards the outside of the canister on the 60
CFM model.
 The bolt holes are located towards the inside and underneath the canister
on the 100 and 130 CFM models.
Align the SENTRY 1000 Input
The top port of the SENTRY 1000 is the input and must be plumbed to the
process tool exhaust port. Align the SENTRY 1000 input port (top port), which
can be rotated for easier installation, facing towards the process tool exhaust
connection. To rotate the input, use the following steps.
Notice
Do NOT remove the nuts from the 100 and 130 CFM models.
 Loosen counter-clockwise but do not remove the nuts on the top of the
SENTRY 1000.
 On the 60 CFM model only, remove the nuts completely and reposition the
threaded rods.

 Rotate the top of the SENTRY 1000 until the input is facing towards the
process tool exhaust connection.
Notice
• 60 CFM Model: The input rotates at 45 increments.
• 100/130 CFM Model: The input rotates a full 360
 Replace and/or tighten the nuts onto the SENTRY 1000.
Connect the SENTRY 1000 Input and Output
The input and the output of the SENTRY 1000 have been aligned with the
process tool exhaust line and the facility exhaust line respectively. Wherever
possible, use either fixed plumbing or flexible hose of a diameter that is equal to
or greater than the diameter of the SENTRY 1000 input and output. A reducer
adapter may be required to mate the SENTRY 1000 input and output ports to the
appropriate mating connections at the tool and at the facility connection. Where
appropriate, use clamps to secure the connections.
 Connect and clamp the SENTRY 1000 input to the process tool
exhaust using flexible hose or fixed plumbing.
 If it is present, temporarily close the exhaust manual damper or shut-off
associated with this SENTRY 1000 installation.
