1. Overview of PendoTECH PressureMAT
The PressureMAT is a monitor, alarm, and transmitter system designed for use with Single Use
Pressure Sensors from PendoTECH. It is comprised of the control system box with user interface and
the connectors on the back panel where input and output components can be interfaced. If equipped,
the alarm output function includes a dry contact relay output. The transmitter function delivers an
analog 4 – 20 milliamp output signal corresponding to the pressure reading on the display. There are
numerous applications in biopharmaceutical production processes where the system can be used.
The four available models are as follows:
Model Number Number of
Inputs Number of Outputs Outputs
PMAT1 1 2 1 Relay /1 Analog
PMAT2 2 4 2 Relays / 2 Analogs or 4 Relays
PMAT3 3 4 3 Analogs / 1 Relay (for all sensors)
PMAT4A 4 4 4 Analogs
PMAT4R 4 4 4 Relays
System Components Supplied:
•Control system
•Cable(s) for connection of pressure sensors to the control system
•Connectors for cable for each output
•4 Screws for mounting hardware
•Power supply
•RS-232 cable for data output to a PC (if ordered with the system)
1.1. Control System
The control system with its user interface is used to display pressure readings, zero calibrate the
pressure sensor, and to access the program menus to edit the alarm high and low set point values and
other tasks.

PressureMAT User Guide
Revision 1
Page 5/29
The process pressure is displayed on the LCD display for each input channel. High and low alarm
pressure set points are entered on the keypad for each channel and if the process pressure goes below
the low setting or above the high setting, the system will go into alarm state. The alarm function
includes activation of the dry contact relay output, a flashing “ALARM>” indication on LCD on the
same line as the pressure input channel in the alarm state, and an audible tone for 30 seconds. When
an alarm condition goes away, all indicators automatically go back to normal (unless the optional
alarm latching function is turned on which requires STOP to be pressure to clear the alarm). The
alarm functions are always active for all channels.
1.2. Control System Details
1.2.1. Hardware Details
There is no power switch so the system cannot be accidentally turned off. When the wall power
supply is connected to the system and plugged into a wall outlet, the system will turn ON. Instructions
to power down the system without unplugging are in Section 1.2.3. The Front and Back Panels details
are as shown:
FRONT PANEL:
Note: If a pressure sensor is not connected or is disconnected during operation of the system,
the pressure will go to a value greater than 75psi/5.17 bar and an alarm condition will occur.
Associated relays will switch and the analog output will send 20mA.

1.2.3. Software Details
The software interface consists of the keypad (shown below) and the 8 line LCD backlit
display. The program/firmware is stored in memory in the control system and cannot be edited
by users. Only settings in the software menus can be changed. The system does not store any
data.
There is no power switch so the system cannot be accidentally turned off. When the wall
power supply is connected to the system and plugged into a wall outlet, the welcome screen
will appear momentarily followed by 2 beeps then the HOME screen will appear.
Home Screen
When the system is powered on, the following HOME screen appears after the welcome screen
with pressures 1 through 4 shown depending on the model number
(with X.XX bar or XX.X psi as designated):

Navigation Between Pressure Sensor Input Channels
At the HOME screen, the UP/DOWN arrows are used to change the selected pressure input
channel.
Zero Calibration for Pressure Sensors
1. Select the desired input using the UP/DOWN buttons
2. With a pressure sensor connected to the system and EXPOSED ONLY TO
ATMOSPHERIC PRESSURE, press the LEFT ARROW button on the keypad
3. The display should read 0.0 psi / 0.00 bar
4. If 0.0 psi / 0.00 bar is not on the display, press the ZERO TARE button on the keypad
again
Note: a minus sign may appear on the display when it reads 0.0 psi / 0.00 bar; this is
normal as the pressure measured by the system may be a value such as -0.001 but
displayed as -0.0 psi / -0.00 bar.
Alarm Function
If any channel has an alarm, the alarm function includes:
a. A dry contact relay associated with that channel will switch (i.e., if wired as normally
CLOSED, it will OPEN)
b. The display screen will blink “ALARM>” on the channel with the alarm
c. An audible tone for 30 seconds during the present alarm (it is reset for a new alarm
condition)
When an alarm condition goes away, all indicators automatically go back to normal (unless the
optional alarm latching function is turned on). If a sensor is inadvertently not connected or
becomes accidentally disconnected during a process and stops monitoring pressure, there will
be a high pressure alarm notification that pressure is not being monitored.
Program Menu
To access the program menu for a pressure sensor, press the PROG key on the keypad with the
desired input channel selected. The program menu is mainly used for setting of the high and
low alarm set points and alarm detect delay. After pressing the PROG key, the following
screen appears with X indicating selected channel:

2. Using the System
2.1. System Setup
1. Connect the pressure sensor cables to the back panel. If a pressure sensor is not connected
when power is supplied to the system, the pressure will go to a value greater than 5.3 bar and
an high pressure alarm condition will occur on the respective channel(s). If a sensor is
inadvertently disconnected during a process and stops monitoring pressure, there will be an
alarm notification. The associated relay will switch and the analog output will send 20mA.
2. Connect the analog and relay outputs, if required as shown in Section 1.2.1
3. Connect the pressure sensor(s) to the cable(s) connected to the system.
4. Connect system to appropriate power source.
Note: If a pressure sensor is not connected when power is supplied to the system, the
pressure will go to a value greater than 75 psi / 5.17 bar and a high pressure alarm condition
will occur on the respective channel(s) and the relay will switch to the alarm position and the
analog output will send 20mA. If a sensor is inadvertently disconnected during a process and
stops monitoring pressure, there will be an alarm notification. Also, a new sensor that has
not been zero-calibrated can bypass an alarm set-point triggering an alarm condition.
5. Using the instructions from the previous section 1.2.3 and while the sensor(s) is at atmospheric
pressure, zero calibrate the sensor(s) being used (if not reading 0.0 psi / 0.00 bar when
installed) by pressing the LEFT ARROW button with the proper channel selected.
