calibration parameters on board and have 0.01% IS-50 or optional 0.008% IS-33 accuracy.

The three transducers, in combination with the internal control valve regulator, provide a dynamic output.
The operator can choose to control pressure either using a single, selected transducer or auto-range
control across all three transducers. The ratio between the highest FS range and the lowest FS range
within the CPC8000 cannot exceed 10:1. The three ranges can be chosen to optimise accuracy levels

across the full pressure span of the instrument.

In addition to the capacity for three active ranges, a fourth, barometric transducer is available as an

option. With this option installed a CPC8000, with absolute or gauge pressure transducers, can emulate

pressure of the opposite type.

3.1.1 IntelliScale Transducer Choices

The CPC8000 can be supplied with standard 0.01% IS-50 Transducers or optional 0.008% IS-33 trans­ducers to give a percent of reading accuracy down to 50% or 33% of full scale respectively. Refer to Sec-

tion 4, Specications, for a full description of the accuracy specication and Section 4.7, IntelliScale.

the individual features on the various displays is included in Section 6.1.2.

Main screen

Test / Calibration Parameters

Figure 3.2.4.1 - Main Screen Features

3.2.4.2 Screen Navigation

Individual screens are accessed by a series of touches on tabs, buttons or icons, which open screens
within the hierarchy of the instrument. Nomenclature that designated a screen and how to navigate to
it will be given in this manual in the following structure: “Icon name” [Icon Graphic] / [Tab] / [Button
Name].

Data entry

For example the screen used to set the resolution of the instrument transducer would be designated by

the navigational screen hierarchy, starting from the main screen, as follows: Setup [ ] / [Sensor]
/ [Resolution]. This convention is similar to a computer folder system and will be used to describe a

screen and, inherently, how to navigate to it.

All of the screens are set up into two display areas. The larger area (left 2/3 of the screen) shows live
information about the current conguration, the progress of the test being performed and gives an indica­tion of the output of the device. The smaller area (Data Entry) on the right side, has the number key pad,

variable sliders or discrete choice buttons (radio buttons) that all act to input alpha numeric information or
mode changes relating to the test or calibration information being shown on the left.

4.4 Transducer Removal/Replacement

When replacing transducers the order of position MUST be maintained according to
the pressure limit of each transducer; starting with the highest pressure transducer
on the left (Primary Transducer), and the next lower pressure limit transducer next
(Secondary Transducer), and the low ranged transducer at the far right (Tertiary
Transducer). If the system will be operated with less than the full complement of
three pressure modules, any empty slots must begin at the far right where the
Tertiary Transducer is normally located.

The manifold seal is a metal plate used to seal the pneumatic openings on the manifold at
an unused transducer slot. If there is just a single pressure transducer installed then two

manifold seals are installed. All transducer slots must be sealed with either transducers or

seal plates for the instrument to function. Two manifold seal plates are shipped with each

unit for this purpose.

The D-sub connectors for unused slots can remain unplugged. For more information on transducer re­moval/replacement see Section 10.2.2 in the Maintenance section.

Up to three transducers can be present within the CPC8000. The full scale pressure of the highest

ranged transducer (the Primary transducer) must fall within the range of the installed regulator module

(see Table 4.5, Regulator Module version and range limits). This primary transducer occupies the leftmost

slot within the CPC8000 (see gure 4.4). The other two slots can be empty or occupied with lower ranged

transducers but their full scale range cannot exceed a ratio of 10:1 of the primary transducer. In other
words, the lowest full scale range in the CPC8000 cannot be less than one tenth of the range of the
primary transducer full scale range (see Section 4.6, Transducer Choices).

Figure 4.5 - Primary transducer limit for each regulator

The primary transducer (Transducer 1) full scale range must fall within one of the regulator range limits
shown in gure 4.5. The secondary and tertiary transducers may fall outside of these limits but must not

have a full scale value less than 1/10 of the primary transducer full scale range.

4.6 Transducer Choices

Transducer measuring modes can be gauge, absolute, or bi-directional. The CPC8000 will be equipped
with one, two or three transducers of the same mode. Transducer type will be “Standard” (accuracy of

0.01% FS, or 0.01% IS-50) or “Premium” (accuracy of 0.008% IS-33, or 0.008% IS-50). The transducers

must be all “Standard” transducers or all “Premium” transducers and not a mix of both types.

The three transducers, in combination with NVR Module, provide a wide dynamic range (10:1 FS) where

the operator can choose to control output pressure using a single transducer, or “autorange” control

across all three transducers. The three transducer ranges can be chosen to optimize accuracy levels.
Full scale transducer ranges up to 6000 psi are available plus an optional barometric transducer. The
accuracy specications, plus a proprietary needle valve regulator, provides accurate and stable control.

The number of unique readings/sec over the remote interface is dependent on the transducer type. The
transducer update rate of a standard transducer is 30ms, or 33 unique readings/sec. The transducer
update rate of a premium transducer is 100ms, or 10 unique readings/sec. This is a technical limitation
of the premium transducer required to meet performance specications. All remote protocols can query

faster than the transducer update rate.
An optional precision barometer can be used for emulation of gauge pressure with an absolute pressure

instrument, or used for absolute pressure emulation with a gauge pressure instrument. For full range

absolute emulation, the instrument gauge transducers should be ranged down to -15 psig.

4.7 IntelliScale

IntelliScale is a calibration technique that provides another degree of certainty to a pressure
measurement specication. Or said another way, IntelliScale is designed to further reduce the accuracy
specication. It does this by considering the full pressure range as two separate ranges; a specically
dened lower range, and the remaining upper range. It then denes the accuracy of the lower portion

as a percent of the full scale of that lower range, and the accuracy of the upper portion as a percent of
reading at any pressure point within that upper range.

In practice, the standard Mensor IntelliScale specication is 0.01% IS-50. This means that the full scale
lower half (50% of the total range) has an accuracy of 0.01% of that portion of the range, while the upper
half of the total range has an accuracy of 0.01% of the pressure reading. Thus, any pressure within the
lower half of the pressure range has a xed number for the accuracy (.01% of that half scale), while the
accuracy anywhere in the upper half of the full range is a sliding scale number; that is, a percent (0.01%)

of any reading.

For example, a device with a pressure range from 0 to 100 psi with an accuracy specication of IntelliS­cale 0.01% IS-50 will have an accuracy of 0.005 psi (0.01% x 50 psi FS) on any pressure from 0 psi to 50
psi, and an accuracy of 0.01% of reading (0.01% x R) for any pressure above 50 psi (see gure 4.7.1a).

4.7.1 Optional IntelliScale

An option available for some ranges is IntelliScale 0.008% IS-33, where the lower portion of the full scale
range is 33% of the total range, and the upper portion of the full scale range is 67% of the full range. The
result is an accuracy of 0.00264% (0.008% x 33% FS) of the total full scale pressure for the one third low
end range, and an accuracy of 0.008% of reading (0.008% x R) for any pressure in the upper two thirds
of the transducer range. See gure 4.7.1b.

5.4 Turning on the CPC8000

After the pressure connections are secure in accordance with Section 5.5 below, apply power to the power
connector on the rear of the instrument and switch the power switch 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 an operating screen similar to the screen shown in Section 3.2, Front Panel. Allow the instrument at least
30 minutes of warm up time before performing critical pressure measurements.

Earth Ground! Any power adaptors or surge protection devices that negate the
protective earth ground should not be used. The power cord must be accessible
and contain a protective earth ground.

Ventilation! Do not block airow to ventilating fans located on rear of instrument.

The instrument can be set up on a table top or it can be rack mounted. Rack mount adapters are option­al.

After the controller has warmed up, cycle the pressure from the minimum to the maximum then back to
the minimum pressure of the primary transducer with the desired volume connected to the Measure/

Control port. This will allow the controller to properly compensate for the dierence in external volume
between what was used at the factory versus what is currently in use. This pressure cycle should occur

after each power cycle, or when the external volume size has been changed.

5.5 Pressure Connections

Warning! The pressure connections must be installed according to the following

instructions, observing the relevant regulations. The installation is to be performed
by trained, authorized personnel, knowledgeable in the safety regulations for
working on pneumatic/hydraulic systems.

Up to 6 pressure connections are on the rear panel. Pressure connections that are not

assigned are plugged.

■ Supply

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 (see the label on
the lower right of the front panel).

■ Exhaust

The pressure connection labeled “Exhaust” is for the vacuum supply. In a gauge pressure version it

can be left open to atmospheric pressure.

If the instrument’s primary pressure range has the minimum pressure in the vacuum region but

is not negative atmosphere, a vacuum regulator will be included. The vacuum regulator included

(6100500023) will need to be connected in-line between a vacuum pump and the exhaust port of the

instrument in order for the instrument to control properly. This vacuum regulator will need to be set to
10% below the minimum range of the primary transducer of the instrument. The vacuum regulator can
be set using a at-head screwdriver.

■ Vent

The pressure connection labeled “Vent” is the exhaust port where the system pressure is vented to the
atmosphere under certain conditions. Leave this port open or connect the optional muer for noise

reduction.

■ Reference

This is the pressure connection to the reference ports of transducers with ranges <50 psi (4 bar)

gauge.

The Reference port should be left open to the atmosphere and should NEVER be connect­ed to a pressure source.

The higher the supply pressure connected to the Supply port, the higher the pressure which leaves the

system through the exhaust port. If a vacuum pump is connected to the exhaust port, adequate safety
precautions have to be taken to prevent damage to the pump.

If vacuum is connected to the Exhaust port of the controller, negative pressure peaks might occur at the
Measure/Control port for a very short time, when changing from the Measure mode to the Control mode.

Before the system is connected, the user must ensure that suitable protection measures are in place

which exclude overpressuring of the test piece or the system.

■ Measure/Control

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 instrument transducer.

■ Barometric Reference

The Barometric Reference port is connected to the internal barometric transducer and should be
left open to atmospheric pressure.

5.6 Pneumatic Connections and Pressure Fittings

The CPC8000 is supplied with ve 1/4 in. tube OD x 7/16-20 male SAE/MS straight thread adaptors or
ve 6 mm tube OD x 7/16-20 male SAE/MS straight thread adaptors (per order). The 7/16-20 male SAE/
MS straight thread end of the adaptors should be connected to the instrument’s 7/16-20 female SAE/MS
straight thread connections. The adaptors need only be “wrench tight” for proper sealing. Connections
should be made according to your specic requirements ( for example, a vacuum pump is only required

when controlling to a subatmospheric pressure).

For functional testing and to become familiar with the operation of the CPC8000, a volume

close to the volume expected during normal operation can be connected to the Measure/
Control port.

WARNING! The user must ensure that released pressure medium does not endan­ger personnel, environment or the instrument.

Test items with large volumes or long piping runs with small diameter tubing can have a
negative eect on the control performance.

CPC8000

5.7.1 Notices Regarding the Electrical Connections

5.7.1.1 Power Supply

WARNING! Before connecting the power supply, make sure that the power voltage

agrees with the voltage specication of the CPC8000. Switch o the system before

connecting the power.

The 3-pin power cable supplied is tted with a ground lead. The system should only be operated from a

3-pin socket with the ground lead properly connected.

5.7.1.2 Interfaces

WARNING! The interface cables must not be longer than 3 meters and must be
separate from cables with voltages greater than 60 volts.

5.7.1.3 Ethernet Interface

The Ethernet jack is a standard Ethernet interface used for remote communication.

5.7.1.4 USB Host Interface

The USB Host interface is a service port used to upgrade software and download information from the
device. It has the same function as the USB Host port on the front of the CPC8000.

5.7.1.5 USB Device Interface

The USB Device jack is a standard USB Type B receptacle interface used for remote communication. The
USB Driver can be downloaded at http://www.mensor.com/download_software_drivers_en_um.WIKA

5.7.1.6 RS-232 Interface

The RS-232 interface is a 9-pin D-Sub socket used for remote communication.

5.7.1.7 IEEE-488 Interface

The IEEE-488 interface is an IEEE-488 socket used for remote communication.

5.7.1.8 Input/Output Port

CAUTION! The Input/Output port has eight digital inputs that will accept either 3.3 VDC or
5 VDC signaling. Each input consumes about 8-10mA. If a voltage greater than 6VDC is
applied to an input it will be permanently damaged.

The Input/Output port also has eight relay outputs. Both normally open and normally closed contacts are
available for each output on the port. The contact ratings for the relays are as follows:

■ Rated load (resistive): 0.5A @ 125VAC, 1A @ 24VDC

■ Rated carry current: 2A

■ Max. switching voltage: 125VAC, 60VDC

■ Max. switching current: 1A

■ Max. switching power: 62.5VA, 30W

The instrument can be set to respond to the digital inputs and to change the outputs based on certain

conditions. See section 7.5.2.5.8.

6. Local Operation

6.1 General

This section describes the procedures for operating the CPC8000 from the front panel. Instructions for
operating the instrument from an external computer are covered in Section 8, Remote Operation. By
following the procedures provided in these two Sections and in Section 7, Setup, you can expect your

CPC8000 to deliver maximum accuracy and dependability for many years of exceptional service.

When the instrument is powered on it will take about 30 seconds to boot up. At the end of the boot
process the display screen similar to gure 6.1 will appear. This is the main operating screen. At this point

the CPC8000 is ready for operation. However, for critical tests and measurements allow the unit to warm
up for at least 15 minutes with power on to ensure rated accuracy.

Notice that the portion of the screen with a blue eld covers about two-thirds of the total screen area. This

area contains the pressure output reading, the setpoint, the active transducer range, units of measure,

limits and a choice between the control modes: Measure, Control or Vent.

The sidebar to the right (black eld) is used for entering data, adjusting environmental settings, dening
parameters for remote operations, and making choices in the conguration. Several dierent sidebars
can be accessed from the main screen to achieve dierent objectives.

This section of the manual will explain features of this main operating screen and the associated

sidebars.

Data entry

Beyond the main screen are a series of setup screens used to adjust parameters and conditions, such as

performing calibrations, running programmed routines, operating from a remote computer, etc. All such
setup screens are on black backgrounds, and have their own sidebars (also black) for choice menus and
data entry. Explanations and instructions for using these setup screens are covered in Section 7, Setup.
