3. Product Description

3.1 General Description

The Mensor CPC 6000 Automated Pressure Calibrator is a multi-channel/multi-range pressure system designed to test and calibrate a variety of pressure devices in either absolute or gauge pressure modes. The CPC 6000 can have two independent control channels each with its own pressure regulator. Each control channel can have up to two transducers. Transducers can be of two types:

“Intelliscale Transducers” (IS) or “Turndown Transducers” (TD).

Intelliscale Transducers (IS) have an accuracy of 0.01%Intelliscale-50 (0.01%IS-50). This specification is a percent of reading specification with a 365 day calibration stability and is explained in Section 4 of this manual. The 0.01%IS-50 specification is available in all new CPC 6000’s and applies to full scale ranges above 15 psi absolute or gauge. CPC 6000s with software version 1.25 and below require a software upgrade to version 1.26 or greater to be able to communicate with Intelliscale Transducers.

Turndown Transducers (TD) can have two ranges configured on each transducer. These ranges are referred to as turndowns and each one has an uncertainty of 0.01%FS with a calibration stability of 185 days. The second (lower span) turndown cannot have a span that is less than 50% of the primary turndown span. Turndown Transducers can be used in all CPC 6000 sofware versions.

Below is a software version comparison matrix.

3.2 Features

Here is a short list of significant features designed into the CPC 6000:

1.0.01%Intelliscale-50 Uncertainty.

2.Up to four (two per channel) highly stable, temperature compensated, pressure transducers.

3.An optional internal high accuracy barometric reference transducer provides gauge pressure emulation for all of the absolute ranges and absolute pressure emulation for gauge ranges;

4.All pressure transducers are individually removable from the front of the CPC 6000 without the use of tools (excluding the barometric transducer). This feature greatly facilitates “out of instrument” recalibration of individual transducers using the optional Calibration Sled (see Section 8, Options);

5.Two precision pressure regulators are selectable for controlled output pressure. These regulators have a history of excellent control and stability;

6.A separate electrical module using a high speed microprocessor. The operating program is loaded from a non-volatile flash disk;

7.A large color SVGA LCD display with a touch screen for intuitive operator interface;

8.Multiple languages; change the language for on-screen text and number/date formats instantly by simply touching one of the “national flag” cues available on the display The current language selections available are listed under ‘6.3.2 - Flag Symbol ‘in Section 6, Local Operation.

Operate the CPC 6000 while it is either sitting on a bench or mounted in a standard equipment rack. Leveling the instrument is not a consideration since the pressure sensors are not affected by orientation. Use either front panel input (Local Operation), or send commands and queries over a bus from a separate “host” controller (Remote Operation).

3.3 Front Panel

The CPC 6000 front panel (Figure 3.2) includes an 8.4 inch color SVGA display featuring touch screen technology. Operator input is accomplished by pressing the words or symbols presented on the display. There are no discrete keypads or switches on the front panel.

On the right hand side of the front panel, there is a clear window which shows the calibrated pressure ranges of the internal transducers and the instrument serial number.

To gain access to the internal modules simply loosen the two thumb screws on the right hand edge of the front panel and swing it open (Figure 3.3). In the front of the instrument directly below the electrical module are slots to accommodate two pressure transducer modules on each control channel. Each transducer can be removed and reinstalled through the front panel opening. See Section 9.3.1, Transducer Removal, for additional information on module removal and replacement.

3.4 Display

When the CPC 6000 is powered up it takes about one minute for initialization, then displays a screen similar to Figure 3.4. The display is made up of rectangles which display text or symbols.

Figure 3.4 - Terminology of Screen Elements

Keys, Tabs, Labels or Windows: In this manual a key is a small rectangle which acts as a switch when pressed. Keys have borders with a three dimensional, shadowed effect. Tabs are a group of touch points, each of which will overlay most of the screen with one page related to its title subject. Labels or Windows are small rectangles with solid borders that display information, but do not respond to being touched.

Keys: Keys cause something to change when they are touched. Throughout this manual keys are represented with the displayed characters enclosed in brackets such as [PSI A]. Each key has a characteristic response when actuated; either an instant, single step response when the key is pressed, or continuously repeating steps while the key is held down, or a delayed response when released. Operators will quickly become accustomed to the particular characteristics of the frequently used keys. Some keys become labels under certain conditions, then resume their key function in other circumstances.

Header Bar: The bar across the top of the screen which displays the Mensor Logo, a title frame, and a national flag is stationary and remains displayed at all times. All of the number formats and text displayed on the CPC 6000 screens will be in the language appropriate to the national flag displayed here such as American English for the USA flag, etc. Touch the flag to access a drop-down window showing all of the languages programmed into the CPC 6000 (see 6.3.2 - Flag Symbol). Touch any flag to change the display to the corresponding language.

3.6 Pneumatic Module

Pneumatic modules come in two types and are referred to in this manual as the “Pump Regulator” or the “Solenoid Valve Regulator”. The pump regulator is used with low pressure sensors specified in Section 4, Specifications. The solenoid valve regulator is used with higher pressure sensors and comes in three varieties:

■High Pressure Solenoid Valve Regulator (HP SVR)

■Medium Pressure Solenoid Valve Regulator (MP SVR)

■Low Pressure Solenoid Valve Regulator (LP SVR)

Pressure limits for all of these are specified in Section 4, Specifications.

Each pneumatic module (Figure 3.6) includes platforms for up to two high performance pressure transducers 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 pressure 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.

3.7 Chassis Assembly

The chassis assembly acts as the housing for the system. The electrical and pneumatic modules are each self-contained inside the chassis, and either can be replaced using basic hand tools. In addition, each pressure transducer is individually removable without tools. Instructions for transducer and module removal are provided in Section 9, Maintenance.

The only moving parts in the CPC 6000 are the fan, the pneumatic flow controller diaphragms and valves, the pump/motor, and the solenoid valve plungers. There are no internal user adjustments or setup switches.

5. Installation

5.1 Unpacking the System

In addition to this manual you should have:

■CPC 6000 Automated Pressure Calibrator

■Power cord

■1/8 inch FNPT fitting adapters fastened to rear panel

■Any accessories ordered

■An envelope containing the Calibration Certificate

Your new instrument was subjected to many hours of functional testing before it left the factory. In addition to testing, the unit was inspected for appearance prior to being packaged for shipment. Upon removal from its carton please examine the instrument for shipping damage. Report any apparent damage to the carrier immediately.

5.2 Dimensions

Figure 5.2 - Dimensions

5.3 Mounting

The instrument can be set up on a table top or it can be rack-mounted. Rack mount adapters are optional on the CPC 6000 and require an adapter panel (see “8.2 - Rack Mount Kit” in Section 8, Options). The special sensors used in the CPC 6000 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.

5.5Pressure Connections

i 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.

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 1/8” NPT adapter fittings with the instrument. The pressure connections can be made to these adapters with the proper mating hardware. We recommend the use of either Loctite® Hydraulic Sealant or new teflon tape on the threads of any male pipe fitting. Do not use sealant on fittings sealed with an o-ring. The integrity of each seal is particularly important since even microscopic leaks can cause errors in pressure measurements. The rear panel connections and a complete pneumatic schematic, including the optional secondary transducer, are provided in the Maintenance Section (see Figures 9.2.1C and 9.2.2B). Requirements for connecting to the ports on the CPC 6000 manifold are as follows:

5.5.1 Supply Port

Connect a source pressure to the SUPPLY port of each channel. See “Source Pressure” in Section 4, Specifications, for supply pressure requirements for various pressure ranges.

CAUTION: The control channels are completely independent. Separate supply

!pressures should be applied to the control channels based on the maximum pressure range of each channel. Applying source pressure higher than the

Caution	recommended pressure can cause permanent damage to the control channel.

iPerformance can be enhanced with a well-regulated source pressure.

Notice

5.5.2 Measure/Control Port

Connect a device to be tested to the MEASURE/CONTROL port. In MEASURE mode the CPC 6000 will precisely measure the pressure at this port.

A pressure value can be selected using the on-screen keypad. That pressure will then be output to the MEASURE/CONTROL port by switching to the CONTROL mode of operation.

WARNING: HIGH NOISE LEVELS! As pressure decreases compressed gas will

!escape out the exhaust port. For ranges above 600 psi high noise levels may result during such pressure releases. To overcome objectionable exhaust noise either

install a muffler or route the port to a remote location.

Warning

CAUTION: Improper use of this equipment may impair protection provided by this ! instrument.

Caution

5.5.3 Exhaust Port

If sub-atmospheric control pressure is required a vacuum pump must be connected to the EXHAUST port. Otherwise, this port may be left open to atmosphere.

5.5.4 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.

5.5.5 Remote Bus Connections

See Section 7, Remote Operation, for connections and commands for operation over ethernet, RS232 serial port or IEEE-488.

5.5.6 Digital I/O Connection
The Digital I/O connection consists of four
pins.
Pin 1: +5 VDC
Pin 2: Input TTL levels. Voltage input
should be limited to > -0.3 VDC
and < +5.3 VDC.
Pin 3: Output, pulled up to 5V with a
10k ohm resistor. Source limited to
450uA, Sink 10mA.
Pin 4: Ground
(See ‘Digital I/O’ in Specifications section.	Figure 5.5.6 - Digital I/O Connection
5.6 Turning on the CPC 6000

After the pressure connections are secure, 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 Figure 6.3B. Allow at least 15 minutes of warm up before performing critical pressure measurements.

WARNING: EARTH GROUND! Any power adaptors or surge protection devices that

!negate the protective earth ground should not be used.

Warning

The power cord is the disconnection device and its outlet should be accessible and

contain a protective earth ground.

!

WARNING: VENTILATION! Do not block airflow to ventilating fan located on rear of Warning instrument.
