3.5 Chassis Assembly
The chassis assembly is the housing for the system. The transducers are self-contained inside the chassis and can be replaced using basic hand tools. Figure 3.5 shows the top view of the chassis with the
cover removed.
Figure 3.5 – Chassis Assembly
3.5.1 Control Module
The control module is referred to as the “Solenoid Valve Regulator” (SVR Module). The SVR Module is
available in four variations depending on the working pressure range:
• Low Pressure SVR Module (LPSVR)
• Medium Pressure SVR Module (MPSVR)
• High Pressure SVR Module (HPSVR)
• Extra High Pressure SVR Module (EPSVR)
Pressure limits for all of these are specied in Section 4, Specications.
Each control module includes platforms for up to two high performance pressure transducers, CPR4000,
which are traceable to NIST standards. Both of these transducers can be used in conjunction with the
highly stable pressure regulator to produce a precise output. Each transducer includes its own on-board
compensation and calibration data so that any transducer can be replaced in the instrument without
requiring a recalibration.

5.3 Mounting
The instrument can be set up on a desk top or it can be rack-mounted. Rack mount hardware is optional
on the CPC4000 (see Section 5.2 Dimensions and Section 8, Options).
The special transducers used in the CPC4000 are relatively insensitive to tilt and vibration. However to
further assure stability and accuracy, avoid mounting the instrument on surfaces subject to excessive motor or machinery vibration.
5.4 Rear Panel
Five pneumatic pressure ports are located across the rear panel. Any instrument containing sub-atmospheric pressure ranges needs a vacuum pump to be connected at the exhaust port. The instruments
with pressures above or at atmospheric pressures will have the exhaust port open. Next to the ventilation
fan is a 10-32 UNF tting which is connected to the barometric reference if installed. Below the ventilation
fan is the connection to drive the automatic contamination prevention system. Positioned on the right side
is a remote communication connections; RS-232, Ethernet, IEEE- 488, USB along with the USB host
connection.

Notice
All pressure ports on the rear apart from the Vent Port are female 7/16 - 20 SAE/MS straight threads per
MS16142 and SAE J514 table 14. Connected adaptors require a tube tting boss seal with an o-ring per
MS33656. Mensor can provide a variety of adapter ttings (see Section 8 Options) with the instrument.
Do not use sealant on ttings sealed with an o-ring. The integrity of each seal is particularly important
since even microscopic leaks can cause errors in pressure measurements.
Operating Instructions - CPC4000 23

5.4.2 Supply Port
The pressure supplied to the pressure connection labeled “Supply” should be approximately 10% higher
than the full scale of the highest pressure transducer installed in the controller or 10 psi, whichever is
greater (see section 6.2.1).
5.4.3 Exhaust Port
The pressure connection labeled “Exhaust” is for the vacuum supply. In a gauge pressure version it can
be left open to atmospheric pressure.
5.4.4 Vent Port
The pressure connection labeled “Vent” is the exhaust port where the system pressure is vented to the
atmosphere under certain conditions. This port has a breather vent installed that acts like a muer. Leave
this port open.
5.4.5 Measure/Control Port
The Measure/ Control port (when in the Control mode) supplies pressure that is precisely controlled by
the controller. In the Measure mode, a pressure applied to the Measure/Control port is measured by the
internal transducers.
5.4.6 Reference Port
The pressure connection labeled “Reference” is the reference port, it is available to connect to the reference side of the transducer. This port is normally left open to atmosphere but may be connected to a
stable reference pressure. In an absolute pressure transducer this port is not used.
5.4.7 Barometric Reference Port
The Barometric Reference port is connected to the optional internal barometer and should be left open to
atmospheric pressure.
5.5 Remote Communication Connections
See Section 7, Remote Operation, for connections and commands for operation over IEEE-488, Ethernet, USB or RS-232 ports.
5.6 Power Up
Apply power to the power connector on the rear of the instrument using the power cord included, and
switch the power switch on the front of the unit ON. The instrument will go through an initialization process and system check. As soon as the system check is completed the system will default to a screen
similar to the one shown in Section 6.1.2 - Display Screen Features. The main screen may be congured
in many dierent ways but initially it will be in a default conguration. Subsequently, the unit will power
up in the conguration that it was in when last powered o. Allow at least 15 minutes of warm up before
performing critical pressure measurements.

6.4.3.8 Detection Flags
The CPC4000 Industrial Pressure Controller is equipped with three detection ags that can be enabled
or disabled by the user as needed. These detection ags appear in the Control Settings App. The primary purpose of these detection ags is to protect the instrument and to ensure desired operation. Each
of these ags can be turned “On” or “O” as per user’s need. Figure 6.4.3.8 shows the detection ag set-
tings.
• Supply Detection Enable: If turned “On”, this ag allows the user to check for sucient supply pres-
sure at the Supply Port of the instrument. In case the supply pressure is less than over 10% of the
control setpoint, an error is reported which can be seen in the Troubleshoot App by clicking the error
symbol [ ]. This ag is turned “O” by default.
• Burst Detection Enable: If turned “On”, this ag allows the user to protect the instrument against sud-
den bursts in the pressure at the Measure/ Control Port. In case a burst is detected, an error is report-
ed which can be seen in the Troubleshoot App. This ag is turned “On” by default.
• Measure Regulation Enable: If turned “On”, this ag allows pressure to be controlled while the instru-
ment is in “Measure” mode to prevent pressure leaks in the system over time. This will turn on the internal pressure regulator periodically to control pressure in a certain range of the measured pressure
value. This ag is turned “O” by default.

7.5 Mensor Command Set
This Mensor command set is the default on the CPC4000. For queries (ending with a ?), the Data column
represents the response of the CPC4000. All response strings begin with a space character or an “E” representing that there is an error in the error queue. All response strings are terminated with a <CR> and a
<LF>. The error queue holds the last 10 errors identied.
For all commands (no ?), the data column represents the required parameters to be sent to the CPC4000
following the string in the command column. For any command that requires multiple parameters to be
sent, the parameters must be separated by commas.
7.5.1 Command and Query Format
Commands must be sent in ASCII format and terminated with either a carriage return (<cr>), linefeed
(<lf>), or both. Commands are not case sensitive. Each query returns a response. If an error is detected
the response will include an error ag.
CommandorQueryeld: Unless otherwise specied, commands are typically converted to queries
by appending a question mark to the command. Table 7.5.4 lists all of the CPC4000 command or query
keywords.
Dataeld:The data eld is either in ASCII {string} or numeric {value} form. In the case of multiple data
elds, commas are required to separate the elds. Queries do not have a data eld. String (text) or value
(numeric) data are acceptable in any of the following formats:
Examples of {string} data: ON, OFF, mBar, inHg
Examples of {value} data: 1, 1.0, -5.678, 25.68324e-5
7.5.2 CommandSetDenitions
In this manual, a data entry made up of alpha characters is dened as a string, as opposed to data
containing only numbers, such as “Enter 1 for ON or 0 for OFF” where 1 and 0 are dened as values.
Command: Any command or query listed in Table 7.5.4. For commands that take boolean data the following strings are acceptable:
0 1
False True
No Yes
O On
Separator: Space (SP).
Data: ASCII representations of numbers, {value}, or alpha characters, {string}, data as dened above.
When sending code a literal variable replaces the brackets and the enclosed character(s) shown in the
following examples.
Termination: Linefeed (LF) or carriage return (CR) is used to signal the end of a command statement.
For IEEE-488.2 operation “EOI” is an acceptable alternative.
Always send commands in one of the following formats:
1. [Command] [Termination];
2. [Command] [Separator] [Data] [Termination];
3. Queries are special instructions in the form: [Command?] [Termination] where the question mark, “?”,
immediately precedes the terminator.
When a valid query is received, the CPC4000 will return {data} terminated by CR and LF. Floating point
data is returned in the current engineering units in exponential format.

Autozero none Re-zero all the ranges. These adjust-
ments are not password protected
and are saved permanently through
power cycles while the instrument
is in native mode (temporary while
in emulation mode). This command
takes approximately 60 seconds but
may take longer depending on the
time to become stable.
Autozero? S,T,X,X Returns autozero data where S
represents state (0 = complete, 1 =
local autozero, 2 = remote autozero),
T represents the estimated time to
complete in seconds, and x is a (0)
character since this data location is
not used at this time.
Autozeroabort none Aborts autozero. Any transducers that
have been zeroed will not revert to
previous zero osets.

7.6.1 SCPI Commands and Queries
The WIKA SCPI command is compatible with older WIKA instruments such as the original CPC8000
Notes:
1. Note that WIKA and Ruska 7010 Emulation return slightly dierent responses to some queries.
2. Except for the engineering units selection, the numeric sux selects the applicable transducer [R]:
1 = Sensor 1
2 = Sensor 2
This numeric sux [R] always defaults to the active transducer if not specied.

7.9 USB Software Upgrade
The instrument software can be upgraded to the most recent release by copying the instrument software
from the Mensor website onto a USB device. The instrument software is device specic and the software
for any other instrument apart from the CPC4000 is not accepted by the instrument. The user can then
plug the USB device to the USB port on the front panel of the instrument for an easy upgrade. The instru-
ment recognizes this device by displaying a USB icon on the top bar of the screen (gure 7.10). The user
can navigate to the Software upgrade menu by clicking on the USB icon. The software upgrade menu
gives the user information on the current instrument software and the version of instrument software on
the USB device (gure 7.10-A).
The user can load the instrument software from the USB to the instrument by clicking on the desired version and then clicking [ ] button. The status of the installation can be seen on right one fourth of the
screen.
The user also has the option to copy and load program test sequences (gure 7.10-B) from the USB
drive which can later be accessed through the Programs App menu. Figure 7.10-C shows how to safely
remove the USB drive.

• Remote calibrations sleds (for transducers and/or barometric reference)
• Automatic Contamination Prevention System

8.1 Barometric Reference (CPX-A-C4-6)
The CPC4000 can be ordered with a barometric reference transducer. It is a very stable, absolute pressure transducer used to accurately measure local atmospheric pressure. It is used to display the barometric pressure (reading appears on the bottom right side of the display) or as a barometric reference for
gauge or absolute emulation.
This transducer is in a dierent housing compared to the regular transducers. It is removable by taking o
the top cover of the chassis.
8.1.1 Gauge Pressure Emulation
In the Home Application (main screen) an absolute transducer channel will indicate “Absolute” in the
Pressure Type button (this is the default mode). When the Pressure Type button is pressed the button label will toggle to “Gauge” and have a lighter background color. The lighter background color is an indication that the channel is in emulation mode.
In the gauge emulation mode the atmospheric pressure reading from the barometric reference transducer is subtracted from the absolute pressure reading to emulate a gauge pressure.
The barometric reference transducer has six signicant digits. If a very low pressure gauge transducer
is active and is used in absolute emulation, the combined output may appear quite noisy because of the
resolution of the barometric reference.
8.1.2 Absolute Pressure Emulation
In the Home Application (main screen) a gauge transducer channel will indicate “Gauge” in the Pressure
Type button (this is the default mode). When the Pressure Type button is pressed the button label will
toggle to “Absolute” and have a lighter button background color. The lighter background color is an indication that the channel is in emulation mode.
In the absolute emulation mode the atmospheric pressure reading from the barometric reference transducer is added to the gauge pressure reading to emulate an absolute pressure.
8.1.3 Emulation Mode Accuracy
The accuracy in emulation mode is dierent for gauge and absolute emulation mode.
The barometric reference has six signicant digits and has a guaranteed drift of 0.0000041 psi over a 24
hour period which has no signicant eect on the emulated gauge pressure uncertainty.
The absolute uncertainty of the barometric reference must be considered in the emulated absolute pressure uncertainty.
Operating Instructions - CPC4000 99
Industrial Pressure Controller
CPC4000
8.1.4 Barometric Reference Calibration
The Barometric Reference Transducer can be calibrated in exactly the same manner as the other
installed transducers as described in Section 10, Calibration.
8.1.5 BarometricReferenceSpecications
Accuracy: 0.02% of reading. Uncertainties include all pressure eects and temperature eects over the
calibrated range and calibration stability for 365 days after re-zeroing.
Pressure Range: The standard Barometric Reference Transducer is calibrated from 8 to 17 psia.
Resolution: 6 digits
8.2 Additional Transducers (CPR4000)
A secondary transducer of any standard range, can be purchased as an option. In all other regards, the
add-on transducer will meet all of the specications and operating parameters outlines throughout this

CAUTION: Typically, the pressure regulator in each instrument has limits of 50,
150, 1500 or 3,045 psig. If a transducer is placed into an instrument where the

Caution
transducer has a higher upper pressure range than the instrument’s regulator, the
maximum control limit will be limited to the maximum range of the instrument’s
regulator.
While any transducer will function in any instrument, the results may not always be optimum. For example, if a 1 psi transducer is placed in an instrument that has a 1500 psi upper limit, the controlled pressure
stability may not be acceptable. Or if a 1500 psi transducer is placed in an instrument that has a 30 psi
upper limit, it will control very well, but be limited in resolution.
8.2.1 Secondary Transducer Installation
If the add-on transducer is of a higher full scale range than the existing primary transducer, then this
newer transducer becomes the Primary, and the existing transducer must be moved to the Secondary
Transducer slot. For complete installation instructions see Section 9.3 ,Transducer Removal.
8.3 Rack Mount Kit (CPX-A-C4-R)
A rack mount kit allows the customer to install a CPC4000 into a standard 19” instrument rack. It includes
a tray and a cover panel for the front. The instrument will rest on the tray and be retained by the panel.
