Introduction
The ClimateCraft® is a digital instrument that monitors the operation of ClimateCraft®
FanMatrixfan arrays. A fan array will have two or more fans operating in parallel to provide airflow in
an air handling system. MatrixMonitorsolves the problems of monitoring the airflow of multiple fans
by combining the individual fan airflow readings into a combined reading for the array. MatrixMonitor
provides additional added value features to aid in the operation and maintenance of your fan array.
These features include fan failure detection, surge detection, vibration monitoring and lubrication
monitoring.
MatrixMonitor™ Components
Control Unit
The control unit contains the embedded control system, the
12VDC power supply and the keypad display unit. These parts
are enclosed in a polycarbonate NEMA 4X enclosure with a clear
hinged cover that allows visual inspection of the keypad display
unit while closed. The keypad display unit is mounted on a swing
out dead front panel. Opening the dead front panel allows
access to the embedded control system and power supply. The
parts in the control unit are described separately below.
Embedded Control System
The embedded control system used in the Matruses
a Rabbit® RCM3000 control module made by Digi International.
The control module is mounted on a custom motherboard that
provides all of the input and output connections. It is mounted on the back side of the swing out dead
front panel directly behind the keypad display unit. Swinging the panel out exposes the motherboard
and the control module that is mounted on it. The interface connections to the fan and pressure
transducers and the field connections to the building
management system (BMS) are made on the mother board
with the pull off terminal strips provided. This design provides
easy access to the wiring connections and internal components
of the control unit.
The control unit supplies power to the fan sensors and the
array pressure rise sensor and communicates digitally with
those devices over an EIA/TIA 485 2 wire multi-point
communication line. It can monitor one or two fan arrays with
as many as 49 fans in each array.

A second EIA/TIA 485 (RS485) 2 wire multi-point communication line is provided for communication to
the building automation system (BMS) using the Modbus RTU protocol.
The control unit firmware is written to flash memory on the Rabbit RCM3000 module. It is self-
contained, universal and upgradeable on site

will also light when the grease monitor trips or the fan vibration limits are exceeded.
The keys along with text prompts from the graphic display are used to configure the control to the
application through menu driven setup screens and display real time fan array performance information
screens.
Piezometric Pressure Port
The piezometric pressure port is a pressure tap that is usually inserted into
the throat of the fan inlet cone at its smallest diameter. The tap connection
fitting is on the high pressure side of the cone. The tap is piped from the
downstream side of the cone through the back plate of the fan so that
connection can be made to the pressure transducer located on the inlet
side of the fan air seal wall. If the design flow through the fan is higher than
the rating of the pressure transducer on the fan sensor board (FSB) an
alternate low pressure tap placed higher on the cone will be used. Only one
port will be connected to the pressure transducer on the FSB. The taps are
mounted on the inlet cone with the port end exposed to the flow side of
the inlet cone. They are press fit into the cone and the connection
side is on the
high pressure
side of the inlet cone. The fan sensors are mounted
on the inlet side of the fan back plate so the
pressure tubing that connects to the pressure tap is
routed to the inlet side of the back plate through a
bulkhead connector. The connection is made to the
low pressure side (negative side) of the pressure
transducer on the FSB. The high pressure side of
the pressure transducer is left open to sense the
fan inlet pressure. Throat and

Fan Sensor
The fan sensor is a custom assembly that contains the special MEMS pressure transducer, a temperature
transducer, a tri-axial accelerometer, and a high performance 32 bit RISC microcontroller to read and
process the transducer data and communicate with the host. The fan sensor board (FSB) has the
pressure transducer mounted on the top side and the components and connection points on the bottom
side. It is designed to mount on a standard 2 x 4 outdoor utility electrical box. The pressure transducer

ports are accessible for connecting to the piezometric port. The FSB acts as the box cover. When it is
removed the switches and connections are accessible.
The fan sensors are mounted on the entering air side of the fan back panel. There is one fan sensor for
every fan in the array. The low pressure port (-) of the pressure transducer is connected to the

is open to sense the air pressure at the inlet of the fan.
The fan sensor is mounted on the fan back plate so that the accelerometer can sense the fan vibration.
The FSB microcontroller continuously reads the tri-axial accelerometer data and performs a real time
FFT on the data stream to convert the information from the time domain to the frequency domain
where it can be analyzed. Each fan sensor has a temperature transducer and the host computer in the
control unit calculates the average of all of the sensors in the
array to determine the entering air density for the airflow
calculation. Only the system with the worst vibration needs to
be monitored, substantially reducing the data collection effort.
Each fan sensor board (FSB) is connected to the control unit
through a common dual twisted pair plenum rated cable
(Belden 1325A or equal). One twisted pair is used to supply
12VDC power to the FSB units. The other twisted pair is used
for digital communications between the FSB units and the

cable connection is made at the CPU which goes to the first
FSB on the chain. From there the cable goes to the next FSB
unit. This connection sequence continues until all if the FSB
units are connected. There is no need to maintain a particular
order of connection between specific FSB units because the
control unit can address each unit individually.
The connection from the cable to the FSB unit is
made with a 4 position feed through insulation
displacement connector. The cable wires run
unbroken from the control unit to the last FSB unit
on the chain. This insures the reliability of the
connections. Each twisted pair is foil wrapped and
there is a tinned copper bleed wire running through
the cable in continuous contact with the foil shields
on each twisted pair. At each FSB connection box
the cable jacket and the foils shields are removed to
give access to the conductors. The bleed wire is
never cut. It is connected to ground in the control
unit and runs continuously to the end of the cable where it is left unattached. Each 4 pin conductor has

a strain relief cover attached to keep incidental wire movement from pulling on the connection pins
which insures a good electrical connection between the cable conductors and the connector.
There is a dual DIP switch mounted on the component side of the FSB assembly. This switch is to
activate the line termination resistors.
NOTICE
The dual Dip switches should be in the off position on all of the FSB units except for the
last unit on the cable.
The last FSB unit on the cable should have the switches turned on to tie in the line termination resistors.
It is possible (but not necessary) to have two cables run out from the control unit. A unit with two arrays
might be wired where one cable goes to a first array and the second cable goes to the second array. This
architecture is important when large numbers of fans are used because it increases the ability to deliver
power to the FSB units. When two cables are used the line termination switches must be switched on
for the FSB units on the end of each line. In this case the FSB line termination jumpers on the mother
board in the control unit must be removed.
There are two rotary switches mounted on the component side of the FSB units. These switches provide
the FSB unit with an ID which it uses to communicate with the control unit. These switches must be set
in a specific sequence for the MatrixMonitorto function properly. For array 1, the fan sensor switches

Fan Array Pressure Rise Sensor
The same FSB assembly used for the fan sensor is also used for the fan array
pressure rise sensor. The pressure rise sensor is mounted to the fan air seal wall
on the air inlet side. The high pressure port (+) of the pressure transducer is
connected to the downstream side of the fan air seal wall with flexible tubing to
a bulkhead connector. The low pressure port is left open to reference the air
pressure entering the fan array.

that might be required to do on the job site would be to set the local time and to set the scaling factors
for the analog output signals if they are used by the building management system (BMS).
If it is necessary to replace the Rabbit RCM3000 control module it will be necessary to configure the
system after the module is replaced. The setup data is stored in the flash memory of the control module
and will be lost when the replacement is made. When the firmware is installed default setup data for a
basic one array and one fan unit is stored in the setup data file in flash memory.

need to be modified. If you need to change a

Set the Sensor Position
This selects the position of the piezometric flow tap.
The MEMS pressure transducer used on the FSB
assemblies to monitor the piezometric pressure
depression has a range of 0 to 14 inches WC. The
velocity increases and the static pressure decreases
as it flows through the cone until the minimum
diameter is reached. There is a well-defined
mathematical relationship between the geometry of
the inlet cone, the pressure depression at any point
along the cone and the air flowing through the cone.
By placing a static pressure probe at some point in
the inlet cone and measuring the pressure depression
between that probe and the fan inlet, the airflow can
be calculated.
In most cases 0 to 14 inches WC is sufficient for fan operating conditions used .
ClimateCraft® fans have the pressure tap installed at the minimum diameter, or throat, of the inlet cone
so that the maximum pressure signal is available. If a fan is expected to have abnormally high flow, the
piezometric pressure depression may be higher than 14 inches WC and outside of the range of the
sensor. In those cases, the tap is installed in the cone at a location before the minimum diameter
allowing the FSB pressure transducer to stay in range.

Set the Optional Dampers
This sets a flag if back flow prevention dampers are installed. The dampers can be a control damper or
gravity operated back draft damper. The flag is either Yes or No for the entire array. This flag is used
when a fan failure is detected. If a back draft damper is not installed air back flows through a fan that is
off or has failed. The amount of air that back flows is calculated and then subtracted from the sum of
the flows from the operating fans which gives a true calculation of the airflow delivered by the array. If
back draft dampers are provided, the flow, in the fans that have failed or are turned off, is set to zero
and there is no air back flowing through them.

Set Up Array 2
The set up procedure for Array 2 is almost identical to the
procedure for Array 1 so the instructions will not be duplicated
here. Instead we will describe the minor differences between
the set of Array 1 and Array 2.
The difference between Array 1 and Array 2 is that the number
of fans in Array 2 can be set to 0 and this setting affects the
way the control behaves. One is the minimum number of fans
in Array 1. Zero is the default value for the number of fans in
Array 2. When the number of fans in Array 2 is set to 0, the
control unit inhibits the display of any data for Array 2 and will
not allow any option data to be set. If you attempt to enter
any Array 2 set up screens when the number of fans is set to 0
you will get the following message:
Array2 : Not Set Up!
Select the Number of
Fans First!!
