3. Product description

3.1 Proper use

The CPC3000 High Speed Pressure Controller is a bench top or rack mounted Digital Pressure
Calibrator/Controller used for test and calibration of mechanical pressure gauges, pressure
switches, sensors, transducers, transmitters and any pressure related devices where time to
set point is the most critical requirement.

Only dry clean air or nitrogen should be used as the pressure medium. Shop

air should be avoided and corrosive, oxidizing, condensing, explosive gases

!

Warning

!

Warning

should be strictly avoided.
The maximum permissible supply pressure at the supply port should be
10% over full scale value of the sensor installed.

Very fast pressure changes can damage the sensor, due to mechanical

stress on the sensor; especially if the fast pressure change leads to an
internal pressure which is higher then the full scale of the internal sensor

(even if it is only for a fraction of a second). In some cases, the internal relief

valves cannot react quickly enough to protect the sensor.

!

Warning

The Internal pressure sensors have a calibration certificate for the entire measur­ing chain.

The system is not suitable for use in areas with an explosion hazard.

If the CPC3000 is not used according to this manual, safe operation of the

system is not guaranteed.

The user of the system and not the manufacturer is responsible for all
physical and material damage resulting from improper use!

3.5.1 Keys, tabs, check boxes, labels/graphics

 Keys: There are two types of keys: those that act as a switch to change a condition and

those that open a data entry screen when pressed. Keys have borders with a three dimen­sional, shadowed effect (examples:

, ). Throughout this
manual keys are represented with the displayed characters enclosed in brackets ( Example:
[MEASURE] ) or a description and the actual graphic icon (example: [SETUP]

). Press­ing a key will have one of the following results: 1) instant, single step response, 2) continu­ously repeating steps while the key is held down, 3) the key will change colors indicating that
the associated function is active or 4) a data entry dialog box will open. Operators will quickly
become accustomed to the particular characteristics of the frequently used keys.

 Tabs: Tabs are analogous to tabs in a notebook that allow switching quickly between related

screens. Tabs are keys that allow the operator to switch between a group of screens that have a
similar purpose, for example the

tabs allow the operator to quickly switch between

four screens used to enter the setpoint.

 Check Boxes: Check Boxes

allow for the inclusion or exclusion of specific elements or

conditions.

 Labels and Graphics: Labels and Graphics are text, or graphics that display information, but

do not respond to being touched (examples:

). They indicate choices
that have been made in the setup menus or indicate existing conditions as pressure is controlled or
measured.

3.6 Front panel navigation and variations

Screen Hierarchy: Navigation within the CPC3000 is similar to a computer file system or a web

page. Keys or tabs activate sub-menus. Within the sub-menus there may be related sub-menus
or selections. To return back through the hierarchy of screens the [BACK]
Throughout this manual screen hierarchy will be designated using the following convention:
"main->sub-menu->selection" or "main->sub-menu->tab->selection". Sometimes, a reference
to a key will be made in the context of a specific screen by simply giving the key name in bold
square brackets [KEY NAME] or by using the key name along with the actual graphic icon. The
Hierarchical menu structure is very intuitive and will become more obvious after reviewing follow­ing examples.

Bar Graph: The bar graph shows the relative indication of the range of the internal sensor, the user
defined limits on the internal sensor, the unused portion of the internal pressure sensor range, the
setpoint and the magnitude of the actual controlled pressure. The user defined control limits can
be selected in the Main->Setup->Control screen and can be set to correspond to the range of
the device under test. It is important to note that when the STEP keypad is active in percent
mode, each step is a percent of the user defined limit not the full scale of the internal sensor.
This is useful when calibrating or testing various range devices. Figure - "Bar Graph" shows the
bar graph when the CPC3000 is in vent mode with a setpoint of 2.5 psig. The user defined range is
0 to 4 and there is an unused portion of the internal sensor.

a suitable workspace, connect it, switch it on and configure.

5.2 Unpacking the system

Unpack all components of the CPC3000 carefully and check for damage. Report any damage to
the carrier immediately.

Apart from any additional components ordered, a shipment consists of:

 CPC3000 controller
 Pressure adapter fittings
 Power cable
 Manual
 Calibration certificate
 Optional: Rack mount kit or any other accessories ordered

5.3 Mounting (Rack mount kit option)

Your new instrument can be set up on a table top or it can be rack-mounted. Rack mount adapt­ers are optional on the CPC3000.

A rack mount kit (part number 0018055001) allows the customer to install a CPC3000 into a stand­ard 19" instrument rack. The kit includes rack mount angles as well as rack mount adapter panels
and hardware to mount the instrument.

5.4 Installation

The installation site must meet the following conditions:

 Operating Temperature: 0 to 50°C
 Humidity: 0 to 95 % relative humidity non-condensation
 Flat, horizontal location; secure fixed working surface (desk top model) or installation in a 19"

rack mount.

 At the back of the instrument sufficient air circulation must be provided to avoid an

accumulation of the heat conducted to the outside by the fan.

 During operation, pressure escapes through the vent port in the back of the instrument.

Personnel should not have access to the rear vent and exhaust port during operation.

 The power cord is the disconnection device. Its outlet should be accessible and contain a

protected earth ground.

Avoid the following influences:

 Direct sunlight or proximity to hot objects
 Unstable installation position
 Mechanical vibration
 Proximity to sources of strong electromagnetic fields, such as high tension appliances, mobile

telephones or mains

 Soot, steam, dust and corrosive gases
 Environment with explosion hazard, flammable atmospheres

Pressure supply requirements:

 Stable supply pressure 10% higher than the full scale of the internal transducer
 Permissible media: dry, clean air or nitrogen
 Vacuum: minimum 50 litres/min (if required)

An angle of inclination of the system of more than 3 degrees can cause a deviation
in the measured pressure and should be avoided. Zeroing the unit at the angle of
inclination will nullify this deviation.

Applying supply pressure higher than the recommended pressure can cause

Notice

All of the pressure ports on the rear are female 7/16 - 20 SAE/MS straight threads per MS16142
and SAE J514 table 14. They require a tube fitting boss seal with an o-ring per MS33656. Mensor
provides female pressure adapter fittings with the instrument. The pressure connections can be
made to these adapters with the proper mating hardware. Do not use sealant on fittings sealed
with an o-ring.

performed by persons familiar with, and who can work according to, the
safety regulations for working on pneumatic/hydraulic systems.

When making up a connection to an o-ring adapter port use a back-up wrench to
prevent over-stressing the threads in the manifold block.

5.7 Function of pressure connections

 MEASURE/CONTROL port

Below the label "MEASURE/CONTROL" is a pressure port. In MEASURE mode this port

connects a pressure, applied externally or previously generated by the controller, to the

internal sensor where the pressure is measured (within the range of the internal sensor). In

CONTROL mode this port supplies an output pressure controlled by the internal regulator at the

commanded setpoint.

 SUPPLY port

Below the label "SUPPLY" is a pressure port. This port should be supplied with a pressure that

is between 110% and 120% of the full scale pressure of the internal sensor. In other words,

10% to 20% above the full scale pressure of the internal sensor

supply port”) in the specifications section and pressure media requirements.)

 EXHAUST/VACUUM port

Below the label "EXHAUST/VACUUM" is a pressure port. If a sub-atmospheric control pressure

is required a vacuum pump must be connected to this port. Otherwise, this port may be left

open to atmosphere.

The user must use caution when controlling from a very high pressure down
to a very low pressure when a vacuum pump is connected to the exhaust port.

!

Warning

Large volumes of gas may be present in the device under test and will exhaust

through the Exhaust/Vacuum port in excess of the capacity of the internal
relief valve, possibly causing damage to the vacuum pump.

(see “Maximum pressure -

 VENT outlet

Between the MEASURE/CONTROL port and the REFERENCE port is the pressure outlet. In

VENT mode the pressure within the system is released through this outlet.

HIGH SOUND LEVELS! Pressures from 600 psig and up can generate sound

levels above 100 db for brief periods when they are exhausted directly to

!

Warning

 REFERENCE port

On gauge units this port is connected to the reference side of the transducer, and on absolute

units it is internally capped. This port is normally left open to atmosphere but may be attached

to a snubber assembly on very low pressure instruments.

!

Warning

atmosphere. If no muffling devices are attached to the exhaust or vent port,

then ear protection is advised for personnel in the vicinity of the instruments
that will be operated under such conditions.

The controller must be protected from overpressure.

Pipes, couplings and other components used for connecting the supply,
exhaust/vacuum and the measure/control port must be suitable for the appli-

cation and rated for the applied pressures.

The user must ensure that the pressure media is clean and dry. If necessary,

the internal sensors and mechanisms must be protected by using a liquid trap
or coalescing filter.
