3. Product description

3.1 Proper use

The Pneumatic High-Speed Controller model CPC3000 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 gasses should be strictly avoided.

Warning

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.

Notice

Warning

The Internal pressure sensors have a calibration certificate (see enclosure: 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 personal 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 relat-



ed 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 three 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 graphic 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 variations and navigation

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 key pad 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 control mode controlling a pressure at the setpoint.

5.4 Installation of the system

The installation site must meet the following conditions:

Operating Temperature: 10 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 for to avoid an



accumulation of the heat conducted to the outside via 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.

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, inflammable 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: min. 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.

Notice

Applying supply pressure higher than the recommended pressure can cause permanent damage to the control channel!

5.7 Function of pressure connections

MEASURE/CONTROL port



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

this connection connects the pressure applied to the internal sensor where the pressure

is measured (within the range of the internal sensor). In CONTROL mode this connection supplies an output pressure controlled by the internal regulator at the commanded setpoint.

SUPPLY port



Below the label "SUPPLY" is a pressure connection. This connection should be supplied with a pressure that is approximately equal to 110 % of the full scale pressure of the internal sensor. In other words, 10 % above the full scale pressure of the internal sensor “SUPPLY Pressure” in the specifications chapter for supply pressure and pressure media requirements.)

EXHAUST/VACUUM port



Below the label "EXHAUST/VACUUM" is a pressure connection. 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.

(see

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. Large volumes of gas may be present in the device under

Warning

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.

VENT outlet



Below the label "VENT" is the pressure outlet. In VENT mode the pressure within the system is released through this outlet.

Warning

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

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.

The controller must be protected from over pressure.

Warning

11498171.01 08/2009 GB

WIKA Operating Instruction Pneumatic High-Speed Pressure Controller ∙ Version 1.1 21

Pipes, couplings and other components used for connecting the supply exhaust and the MEASURE/CONTROL port must be suitable for the application and rated for the applied pressures.

The user must ensure that the pressure media are clean and dry. If necessary, the internal sensors and mechanisms must be protected by using a liquid trap or coalescing filter.
