Part One
User Basics
This section is designed to provide a brief but thorough overview of the product installed. These
few pages explain the purpose (The Instrument) and the operation (Useful user information,
Operator panel, Alarms) of the product. Technical product information is available in Part Two of
the manual.
The Instrument
The Model RPM10 and RPM20 Monitors are designed to measure and report room pressure
differential in health-care facilities and other critical environments. They also can measure other
parameters, such as supply flow, exhaust flow, relative humidity, and room temperature.
Useful User Information
The display of the monitor is colored gray, green, or red. Green indicates the room pressure
differential and other configured measurements are adequate. The display turns red to indicate
alarm status when the room pressure differential or another configured measurement has risen
above or dropped below a safe level. The display provides additional information depending on
the configuration of the unit. Gray indicates that the room is in no isolation mode and will not
alarm if room pressure differential is not maintained.
Operator Panel
The Model RPM10 and RPM20 Room Monitors are easy to use. Normal vs. alarm condition and
room modes are always shown on the display. In addition, the displayed can be configured to
show the room pressure differential or all measurements. Specific details about the front panel
display and controls are described on the following pages. The front panel, shown in Figure 1 and
Figure 2 identifies the important features on the display:
Figure 1. Single Room Screen
User Basics
3
Figure 2. Two Room Screen
Display Screen
The LCD display is highly configurable and can display various critical information including
pressure differential, flow rate, alarm status, menu options, and error messages. In addition, the
LCD display is used for programming the unit. When programming the unit, the display will show
menus, menu items, and current value of the menu item, depending on the specific programming
function being performed.
Room Indicator Colors
Green
The screen icon is colored green (NORMAL) when the room pressure and/or other
configured measurements are adequate. This light indicates the room is operating
safely. If a set point cannot be maintained or an alarm limit has been reached, the
green light turns off and the red alarm light turns on.
Red
The room icon is colored red (ALARM) when the room pressure and/or other
configured measurements are not within alarm limits. This light indicates the room is
not operating safely. The display screen will also indicate the type of alarm or an
emergency message.
Gray
The room icon is colored gray to indicate No Isolation mode. In No Isolation mode
the Model RPM10 and RPM20 will not alarm.
Operator Keys
The following keys appear on the display of the Model RPM10 and RPM20 room monitor:
MUTE key
The MUTE key silences an audible alarm. The alarm remains silent until the
MUTE TIME value has been reached or the unit returns to control set point.
ACKNOWLEDGE key
The ACKNOWLEDGE key clears alarms when the Model RPM10 and RPM20
have been set latched alarms under the ALARM RESET item.

Part One
USB Port
There is a USB port on the case. This USB port can be used with TSI’s Configuration Software.
Figure 3. USB Port Location
Alarms
The Model RPM10 and RPM20 monitors have visual (red light) and audible alarms to inform you
of changing room conditions. The alarm levels (set points) are determined by facilities staff, which
could be Engineering, Industrial Hygiene, or a facilities group depending on how the safety staff
is organized.
The audible and visual alarms will activate whenever the field configured alarm level is reached.
The alarms will activate if the room pressure differential is low or inadequate, high or too great, or
when the airflow is too low or too high (need optional flow device installed). When the room is
operating safely, no alarms will sound.
Example: The low alarm is preset to activate when the room pressure differential falls below 0.01 in H2O (closer to neutral). When the room pressure drops to -0.005 in H2O, for
example, the audible and visual alarms activate. The alarms turn off (when set to
unlatched) when the unit returns to the safe range, which is defined as 0.001 in H2O
greater than alarm set point (-0.01 in H2O).
Visual Alarm
The display of the monitor turns red to indicate an alarm condition. The icon turns continuously
red for all alarm conditions.
Audible Alarms
The audible alarm is continuously on in all low and high alarm conditions. The audible alarm can
be silenced by pressing the
key.
If the audible alarm has been muted, the alarm is silenced for a configurable period of time (see
menu item MUTE TIME) or the measurement returns to the safe range. The safe range is
0.001 in H2O (50 cfm) above the low alarm set point and 0.001 in H2O (50 cfm) below the high
alarm set point.
User Basics
5
The audible and visual alarms can be programmed to either automatically turn off when the unit
returns to the safe range or to stay in alarm until the
ALARM RESET).
key is pressed (See menu item
Alarm Relays
The PresSura monitors feature 2 alarm relays. The alarm relays can be field configured to either
open or close to indicate an alarm condition, although they will close on loss of power.
Relay 1 functions as the low alarm relay, and will activate after the alarm delay for low pressure,
low flow, low temperature and low RH alarms. Relay 1 will trigger without waiting for the alarm
delay to indicate a LOM alarm, or low pressure drop across a venturi valve, if a flow input is
configured for venturi valves.
Relay 2 is field-configurable to function as a high alarm relay or to indicate the room status. Refer
to the Relay 2 Out item in the Alarm Config menu for details on this operation.

Part One
Part Two
Technical Section
The PresSura™ Room Pressure Monitor is
ready to use after being properly installed and
configured. The TSI through-the-wall sensor is
factory calibrated, as are most pressure
transducers. Figure 4 shows the Digital Interface
Module (DIM) which is programmed with a
default configuration that can be easily modified
to fit your application.
The technical section is separated into five parts
that cover all aspects of the unit. Each section is
written as independently as possible to minimize
flipping back and forth through the manual for
an answer.
Figure 4. PresSura Room Pressure Monitor
The Software Programming section explains the programming keys on the DIM. In addition, the
programming sequence is described, which is the same regardless of the menu item being
changed. At the end of this section is an example of how to program the DIM.
The Menu and Menu Items section lists all of the software items available to program and
change. The items are grouped by menu which means all set points are in one menu, control
signal items in another, etc. The menu items and all related information is provided including;
programming name, description of menu item, range of programmable values, and how the unit
shipped from the factory (default value).
The Calibration section describes the required procedure to calibrate the controller. This section
explains how to compare the controller’s reading to a portable thermal anemometer and then
adjust the span to establish an accurate calibration. This section also describes how to zero a
TSI flow station transducer (if installed).
The Maintenance and Repair Parts section covers all routine maintenance of equipment, along
with a list of repair parts.
The Troubleshooting section is split into two areas: mechanical operation of the unit and system
performance. Many external variables will affect how the unit functions so it is critical to first
determine if the system is having mechanical problems—i.e., no display on unit, alarms do not
function, , etc. If no mechanical problems exist, look for performance problems (i.e., does not
seem to read correctly, display fluctuates, etc.). The first step is to determine that the system is
mechanically operating correctly, followed by modifying the configuration to eliminate the
performance problems.
Technical Section

Software Programming
Programming the PresSura Model RPM10/RPM20 monitor is quick and easy if the proper
keystroke procedure is followed. The programming keys are defined first, followed by the
required keystroke procedure. At the end of this section is a programming example.
NOTE: It is important to note that the unit is always operating when programming. When a menu
item value is changed, the new value takes effect immediately after saving the change,
not when the unit returns to normal operating mode.
This section covers programming the instrument through the keypad and display. If

ALARM CONSTRAINTS
There are a number of constraints that prohibit you from incorrectly adjusting the set points. These are as follows:
1. Room mode. The positive pressure alarms are only active when positive control is selected. Negative pressure alarms are only active
when negative control is selected. In no isolation mode all alarms are turned off.
2. The PresSura monitor is programmed with deadbands between alarm setpoints to prevent the controller from cycling between high and
low alarms due to normal fluctuations. Setpoint deadbands are:

Pressure = 0.001 in H2O

Flow = 50 cfm

Temperature = 1°F

Relative Humidity = 1%

Position = 1% Open
Example: The control NEG LOW ALM is set at -0.01” H2O. The NEG HI ALM cannot be set less negative than -0.011” H2O.
3. Alarms do not terminate until the room pressure slightly exceeds the alarm setpoint.
4. The ALARM RESET item selects how the alarms will terminate when the controller returns to the safe range. The pressure and flow
alarms all terminate the same; they are either latched or unlatched. If unlatched is selected the alarms automatically turn off when the
value slightly exceeds the alarm setpoint. If latched is selected, the alarms will not terminate until the pressure or flow exceeds the alarm
setpoint and the
key is pressed.
5. There is a programmable ALARM DELAY that determines how long to delay before activating the alarms. This delay affects all alarms,
pressure and flow.
6. The MUTE TIME item temporarily turns the audible alarm off for all pressure and flow alarms.
25
26
7. The display can only show one alarm message. Therefore, the monitor has an alarm priority system, with the highest priority alarm being
displayed. If multiple alarms exist, the lower priority alarms will not display until after the highest priority alarm has been eliminated. The
alarm priority is as follows:
Room 1 pressure sensor – low alarm
Room 1 pressure sensor – high alarm
Room 1 – minimum exhaust flow
Room 1 – minimum supply flow
Room 1 – temperature alarms
Room 1 – relative humidity alarms
Room 1 – supply venturi (low static pressure) alarm
Room 1 – exhaust venturi (low static pressure) alarm
Anteroom pressure sensor – low alarm
Anteroom pressure sensor – high alarm
Room 2 pressure sensor – low alarm
Room 2 pressure sensor – high alarm
Room 1 – supply airflow-proving switch
Room 1 – exhaust airflow-proving switch
8. The low and high alarms are absolute values. The chart below shows how the values must be programmed in order to operate correctly.

Calibration
The calibration section explains how to calibrate the controller and how to zero a TSI flow station
pressure transducer (optional). The Model RPM10/RPM20 Monitor will warn the user with a
display message if it has not been calibrated.
NOTE: This section assumes that the appropriate sensor has been correctly installed. Inaccurate
readings may be detected if sensor is not installed correctly. Review the Installation
Instructions and verify that the sensor is installed correctly (usually only a problem on
initial set up).
Reference measurements, such as from a Portable Air Velocity Meter like the TSI VelociCalc®
Model 9565 or a capture hood like the Alnor® Balometer® Model EBT731, are required to
calibrate the PresSura monitors.
WARNING
The monitor is disabled during calibration. Alarms will not function to warn of
unsafe conditions.
To begin the calibration process, enter the appropriate INPUT# CONFIGURE menu (see
Software Programming if not familiar with keystroke procedure).
Room Pressure Calibration
Room pressure can be measured using either a TSI through-the-wall sensor or a pressure
transducer.
TSI (Through-the-Wall) Sensor Calibration
NOTE: The TSI through-the-wall sensor is calibrated at the factory and does not normally need
adjustment when installed.
1. Select SENSOR SPAN item.
2. Position a thermal anemometer or other instrument configured to measure air velocity in the
door opening to obtain a velocity reading. Take a measurement of the air velocity
entering/exiting the door.
3. Input the reference measurement from step 3 into the PresSura monitor.
4. Save the reading and exit the menu system.
Pressure Transducer Calibration
NOTE: This calibration process is to configure the PresSura monitor to match the reading from
the pressure transducer. If the pressure transducer itself needs to be calibrated, refer to
the instructions that come with the pressure transducer.
1. Write down the output signal range and pressure range of the pressure transducer. As an
example for these instructions, we will assume the pressure transducer has an output signal
range of 0 to 10V and a pressure range of -0.25 to +0.25 in H2O.
2. Select the SENSOR MIN item and enter the minimum pressure range of the transducer. In
this example, you would enter -0.25 in H2O.
3. Select the SENSOR MAX item and enter the maximum pressure range of the transducer. In
this example, you would enter +0.25 in H2O.
59
4. Select the SIGNAL MIN item and enter the minimum output signal of the transducer. In this
example, you would enter 0 V.
5. Select the SIGNAL MAX item and enter the maximum output signal of the transducer. In this
example, you would enter 10 V.
6. To zero the pressure transducer:
a. Mark the high pressure tubing going to the high port of the transducer.
b. Remove the tubing from the high and low ports of the transducer.
c.
Enter the PRESSURE ZERO item on the PresSura monitor.
d. Reconnect tubing to the high and low ports of the pressure transducer, using the mark to
connect the high pressure tubing to the high port.

Maintenance and Repair Parts
The Model RPM10 and RPM20 PresSura Room Pressure Monitors require minimal maintenance.
Periodic inspections of system components as well as an occasional pressure sensor cleaning
are all that are needed to ensure that the PresSura monitor is operating properly.
System Component Inspection
It is recommended that the pressure sensor be periodically inspected for accumulation of
contaminants. The frequency of these inspections is dependent upon the quality of the air being
drawn across the sensor. Quite simply, if the air is dirty, the sensors require more frequent
inspection and cleaning.
Visually inspect the pressure sensor by sliding open the sensor housing door (Figure 13). The air
flow orifice should be free of obstructions. The small ceramic coated sensors protruding from the
orifice wall should be white and free of accumulated debris.
Figure 13: Pressure sensor door slid open
Periodically inspect the other system components for proper performance and physical signs of
excessive wear.
Technical Section
63
Pressure Sensor Cleaning
Accumulations of dust or dirt can be removed with a dry soft-bristled brush (such as an artist's
brush). If necessary, water, alcohol, acetone, or trichlorethane may be used as a solvent to
remove other contaminants.
Use extreme care when cleaning the velocity sensors. The ceramic sensor may break if
excessive pressure is applied, if sensor is scraped to remove contaminants, or if the cleaning
apparatus abruptly impacts the sensor.
WARNING
If you are using a liquid to clean the sensor, turn off power to the RPM10 /
RPM20 PresSura Monitor.
Do not use compressed air to clean the velocity sensors.
Do not attempt to scrape contaminants from the velocity sensors. The velocity
sensors are quite durable; however, scraping may cause mechanical damage
and possibly break the sensor. Mechanical damage due to scraping voids the
pressure sensor warranty.
Display Screen Cleaning
Accumulations of dust or dirt can be removed with a dry soft cloth. If necessary, Isopropyl, or
Ethyl Alcohol may be used to remove other contaminants.

Troubleshooting Section
The Model RPM10 and RPM20 Room Pressure Monitors are designed to be trouble free.
However, installation problems or interaction with other HVAC components may cause system
problems. The system is easy to troubleshoot if an organized approach to evaluate the system is
taken. Troubleshooting is broken down into hardware (mechanical) and software problems.
Hardware problems deal with the physical installation of the device. Hardware problems include
wiring problems, incorrectly installed equipment, and add-ons or non-TSI equipment. Software
problems include control problems, configuration problems, or interaction problems with the
HVAC system.
The hardware test described in this section determines that all TSI mechanical components are
functioning correctly. The hardware test requires the diagnostics menu items to be accessed. If
you are unfamiliar with the controller menus, see Software Programming for keystroke procedure.
Troubleshooting the majority of problems is usually quick if the hardware test is followed.
64
Part Two
Software and hardware problems are covered in the troubleshooting chart. Pick the problem that
most closely resembles your problem and review the possible symptoms and corrective action.
Software or system performance problems can and are affected by the supply air system,
exhaust air system, or physical configuration of the room. Separating TSI system problems from
the laboratory HVAC system can sometimes be difficult. TSI recommends confirming all
hardware is operating correctly before troubleshooting software problems.
Hardware Test
Three tests need to be performed in order to determine all hardware is functioning correctly. The
tests are broken down into:
 Confirming wiring is correct.
 Confirming physical installation is correct.
 Verifying mechanical components.
Confirming wiring is correct
The most common problem with installed hardware equipment is incorrect wiring. This problem
usually exists on initial installation, or when modifications to the system take place. The wiring
should be very closely checked to verify it exactly matches the wiring diagram. Wiring diagrams
are located in Appendix C of this manual. Wiring associated with non-TSI components should be
closely checked for correct installation. If non-TSI components are installed, consider
disconnecting them for testing purposes.
Confirming physical installation is correct
All of the hardware components need to be installed properly. Review the installation instructions
and verify components are installed properly at the correct location. This is easily done when the
wiring is checked.
Verifying mechanical components
Verifying all TSI components are operating correctly requires following a simple procedure. The
fastest procedure to confirm all equipment is operating is to first test the Digital Interface Module
(DIM), and then go into the diagnostic menu to test each component.
NOTE:
These tests require power to the units, so if unit has no power, refer to
hardware troubleshooting chart to eliminate power problem.

Corrective Action
Measure voltage at pins 1 and 2 on DIM 2-pin connector.
The voltage should nominally be 24 VAC.
If correct voltage is measured, internal DIM fuse is probably
blown. Unplug 2-pin connector from DIM for 2 minutes. The
internal fuse will automatically reset. Plug unit back in and
check display. If display is still blank, check all wiring, etc.
Verify circuit breaker is on.

Symptom
Alarm relays do
not work.
Displayed room
pressure or flow
wildly
fluctuating.
Analog output
does not work
properly.
Possible Cause
Alarms are
turned off.
Corrective Action
Enter the Rm1 Alarm, AnteRm Alarm or Rm2 Alarm menu.
Verify that the Alarm Enable item is set to enable the high
or low alarms as desired.
Incorrect wiring.
Check the wiring from DIM relay output to the device that is
connected to the relays.
Relay may be
defective.
Disconnect the wiring (terminals 9 to 12) from relay
contacts. Go into DIAGNOSTICS menu, Relay Outputs
item. Connect an ohm-meter to relay terminals to verify
contact open and closes. Press the Relay1 Toggle or
Relay 2 Toggle button to manually trip the relay.

If relay responds (contact opens and closes), the
device connected is incompatible or defective.

If relay does not respond, relay is defective (may be
caused by incompatible device). Replace DIM.
Supply air is
affecting the
sensor.
Check location of supply air diffusers. They should be
located as far from the pressure sensor as is realistic,
10 feet preferred with 6 feet minimum. Supply diffuser
terminal throw velocity must be less than 10 ft/min at the
sensor. Relocate supply or exhaust as needed.
Display
averaging is
very short.
Lengthen the time constant by entering the
CONFIGURATION menu, DISPLAY AVG item, and
increase the average time.
Monitor needs
calibration.
Calibrate monitor.
Monitor is
connected to
incompatible
equipment.
Enter the DIAGNOSTICS menu, Analog Outpt item. Use
Output 1, Output 2 or Output 3 button to adjust the output.
Change the output value while measuring the output with a
multimeter. If the voltage (current) changes, the monitor is
functioning properly.
If the voltage (current) does not change, disconnect the
analog out device and repeat the above procedure. If
voltage now changes, the monitor is good, and the external
device is defective. If no change occurs, DIM is defective.
Displayed
velocity does
not match
measured
velocity.

Appendix A
Appendix B
Network Communications
Network communications are available on the PresSura room monitors. The PresSura room
monitors can communicate with a building management system through Modbus®, LonWorks® or
BACnet® MS/TP protocols. Please refer to the appropriate section below for more detailed
information.
Modbus® Communications
Modbus® communications are installed in the PresSura room monitors. This document provides
the technical information needed to communicate between the host DDC system and the
PresSura room monitors. This document assumes the programmer is familiar with Modbus®
protocol. Further technical assistance is available from TSI if your question is related to TSI
interfacing to a DDC system. If you need further information regarding Modbus® programming in
general, please contact:
Modicon Incorporated (a division of Schneider-Electric)
One High Street
North Andover, MA 01845
Phone (800) 468-5342
The Modbus® protocol utilizes the RTU format for data transfer and Error Checking. Check the
Modicon Modbus® Protocol Reference Guide (PI-Mbus-300) for more information on CRC
generation and message structures.
The messages are sent at 9600 baud with no start bit, 8 data bits, and 2 stop bits. Do not use the
parity bit. The system is set up as a master slave network. The TSI units act as slaves and
respond to messages when their correct address is polled.
Blocks of data can be read from each device. Using a block format will speed up the time for the
data transfer. The size of the blocks is limited to 255 bytes. This means the maximum message
length that can be transferred is 255 bytes. The typical response time of the device is around
0.05 seconds with a maximum of 0.1 seconds.
Unique to TSI
The list of variable addresses shown below skips some numbers in the sequence due to internal
PresSura room monitors functions. This information is not useful to the DDC system and is
therefore deleted. Skipping numbers in the sequence will not cause any communication
problems. If a variable is not used by the particular PresSura room monitors, it will be reported
with a value of -1.
All variables are outputted in English units: ft/min, and cfm. If the DDC system is to display
different units, the DDC system needs to make the conversion.

RAM Variables
RAM variables use the Modbus command 04 Read Input Registers. RAM variables are read only
variables that correspond to what is shown on Digital Interface Module (DIM) display. TSI offers a
number of different models, so if a feature is not available on a unit, the variable is set to 0.

XRAM Variables
These variables can be read using Modbus® command 03 Read Holding Registers. They can
be written to using Modbus® command 06 Write Single Register. Many of these variables are
the same “menu items” that are configured from the monitor keypad. The calibration and control
items are not accessible from the DDC system. This is for safety reasons since each room is
individually setup for maximum performance.
