SECTION 1 –INTRODUCTION
The Accutrol® Iso-Tek®is comprised of a high-resolution 7-inch color touch-screen display, a
robust IO Module, and an advanced pressure sensor kit that is designed to measure ultra-low-
differential pressures with a high degree of precision and excellent long-term stability. Field
configuration of the Iso-Tek is made simple using the Accutrol Insight™configuration software.
1.1 Theory of Operation
The Iso-Tek uses a High Pneumatic Impedance Sensor (HPIS®) which refers to the sensor’s
ability to avoid contamination due to the extremely small amount of air that flows through it.
What makes the HPIS unique is that it incorporates a micro-flow-channel etched into the silicon
wafer. This architecture makes the flow channel substantially smaller than other thermal-
based-flow-through sensors, thereby eliminating the disadvantages normally associated with
this type of sensor (see Figure 1).

Advantages of HPIS®
The HPIS combines the best performance features of the diaphragm-based-dead-ended and
thermal-based-flow-through type sensors. The disadvantages normally associated with flow-
through sensors have been addressed through the high input pneumatic impedance of the
micro-flow channel which virtually eliminates airflow through the sensor. The airflow through
the microchannel with a DP = 0.10” WC (25 Pa) is only 0.000005 CFM resulting in an inlet
velocity so low that it is not possible for contaminants to be drawn inside.

(provided by others) typically located at eye level directly outside of the room being monitored.
4.1.1 Installation Steps
1. Insert Display Cable from e-box through the hole in
the Mounting Plate.
2. Position Mounting Plate with the arrow UP.
3. Secure Mounting Plate to e-box using the (4) #6-32
x 1" screws provided.
CAUTION: Do Not Overtighten Screws.
Overtightening may deform Mounting Plate.
4. Plug the Display Cable into the RJ45 connector located
at the back of the Display.
5. Align the three nubs on the top of Display Bezel with
the three slots on the top of the Mounting Plate and
rotate the Display into position over the Mounting Plate.
6. Secure the Display to the Mounting Plate by tightening
the (2) screws located at the bottom of the Mounting
Plate.
4.2 IO Module
The Iso-Tek IO Module is typically located in the vicinity of the room above the ceiling or inside
a control panel located within reach of the Display Cable.
4.2.1 Installation Steps
1. Select a location that is easily accessible with enough clearance to remove the cover
and access the IO terminal blocks for wiring.
NOTE: Iso-Tek IO Modules with the wireless option (-W) shall NOT be installed
inside of a metal control panel or enclosure because the RF signal will be blocked.
2. The IO Module enclosure has four mounting flanges
with 0.2” diameter (5mm) holes. Secure IO Module to
mounting surface using (4) #8 or #10 screws (provided by

7.4.2.1 Room Pressure Alarm Setpoints
7.4.2.2 Room Pressure Alarm Parameters
Alarm in Delay is used to delay the transition period from the normal pressure state to
alarm state based on the value entered. The Alarm in Delay can be used to prevent
nuisance alarms caused by doors being opened for applications that do not have door
switches.
Alarm out Delay is used to delay the transition period from the alarm pressure state to
normal state based on the value entered.
Alarm Mute Reminder Interval is used to provide an audible reminder that an alarm
condition exists however the audible alarm has been muted.
Enable Alarm Mute Expiration is used to put an expiration time on how long an alarm
will remain muted after the mute button is pressed.
Mute the Audile Room Pressure Alarm when Door is Open is used to silence the
audible alarm when the door is open. This will not delay the unit from entering into an
alarm condition, it will only mute the audible alarm. The room must have a door switch
configured to use this feature.
Mute the Audile Room Pressure Alarm for ____ Sec after Door is Opened is used to
silence the audible alarm for a period of time after the door is opened. The room must
have a door switch configured to use this feature.
7.4.2.3 Room Door Open Alarm
Select the Enable box to enable/disable the Door Open Alarm. A time delay can be used
to hold off the door alarm for the programmed interval based on the application
requirements. The room must have a door switch configured to use this feature.
-Click Enable box to enable/disable alarm.
-If enabled, enter the alarm setpoint in the
box provided.
-The example shown is a Positive Room
with a low pressure alarm setpoint of
0.02”wc and a high pressure alarm setpoint
of 0.08”wc.
Alarm Warning Band is based on the
% of the alarm setpoint. In this
example, a high alarm setpoint of
0.08”wc with a 10% Warning Band
would result in a warning when the
pressure exceeds 0.072”wc.

7.5 Analog Output Configuration
The Iso-Tek has two independent analog outputs which can be configured to provide an
analog signal representing room pressure for any two rooms connected to the Iso-Tek. The
analog signal can be configured for voltage or current and scaled per the application
requirements.

7.6 Configuration Pull-Down Menu
-Set Clock: Set the Iso-Tek’s real-time-clock (RTC) to your local time. The accuracy
of the RTC is critical for accurate Event Log performance.
-Altitude Configuration: The altitude of the installed Iso-Tek is important due to
the ultra-low differential pressure that is being measured. To optimize the
accuracy of the differential pressure measurement as installed, enter the altitude
above sea level of the installed Iso-Tek system. The factory default of 300 ft is
based on the location where the differential sensor was calibrated.
