Version 0.1 WIKA Operation Instruction Low Pressure Controller 5
This instruction manual describes the features of the Low-Pressure Controller CPC2000 and
provides guidelines for its use. Improper use of this instrument or failure to follow these
instructions may cause injury or equipment damage. All individuals responsible for operating
this instrument must therefore be properly trained and aware of the hazards, and must
carefully follow these operating instructions and the safety precautions detailed within.
Contact the manufacturer if you do not understand parts of this instruction manual.
Handle this manual with care:
It must be readily available throughout the lifecycle of the instrument.
It must be provided to any individuals who assume responsibility for operating the instrument
at a later date.
It must include any supplementary materials provided by the manufacturer.
Conformity
This instrument corresponds to the state of the art and meets all legal requirements set forth
in EC directives as evidenced by the CE label.
1.1. Safety Instruction
This device has been designed and tested in accordance with the
relevant safety regulations for electronic devices. However, its trouble-
free operation and reliability cannot be guaranteed unless the standard
safety measures and special safety advice given in this manual is
followed when using the device.
1. The system must only be operated by trained and authorized personnel who know
the manual and can work according to them!
2. Trouble-free operation and reliability of the device can only be guaranteed so long as
the device is not subjected to any climatic conditions other than those stated under
―11 Specifications‖.
3. The CPC2000 always has to be handled with the care required for an electronic
precision instrument (protect from humidity, impacts, strong magnetic fields, static
electricity and extreme temperatures, do not insert any objects into the instrument
and its openings). The device and sensors must be handled with care (don‗t throw,
hit, etc.). Protect plugs and sockets from contamination.
4. If the device is moved from a cold to a warm environment, condensation may cause
the equipment to fail. You should therefore ensure the device temperature has
adjusted to the ambient temperature before trying to switch it on.
5. If the instrument is to be connected to other devices (e.g. via serial interface) care
must be taken when designing the equipment connections. It is possible that internal
wiring within the external device (e.g. connection of GND to earth) may cause
excessive voltages which could harm or destroy the instrument or other connected
devices.
6. The mains plug of the CPC2000 must always be accessible when connected to a
power outlet, i.e., you must be able to pull the plug from the power outlet without
difficulty, at any time.
If the device is operated with a faulty mains power supply (e.g. short
circuit from mains voltage to output voltage) this could result in
dangerous voltages at the device (e.g. at the sensor socket or serial
interface)!
7. Significant electromagnetic radiation can adversely affect the measuring signal of the
CPC2000 or even disrupt the display of the signal completely.

8. The display window behind the plastic film is made of glass (which can splinter). If
there is a possibility that this glass incl. the plastic film might break during operation,
anyone in the close vicinity of the equipment must wear eye protectors, both before
and during operation.
9. Test and calibration assemblies must always be constructed and also dismantled in
an unpressurised state (atmosphere).
10. If the CPC2000 comes in contact with oil (which is forbidden), then subsequent use
with fuels or gases is strictly prohibited, since this could cause an explosion and risks
harm to both people and machinery.
11. If the equipment is damaged and might no longer operate safely, then it should be
taken out of use and securely marked in such a way so that it is not used again.
Operator safety may be at risk if:
There is visible damage to the device.
The device is not working as specified.
The device has been stored under unsuitable conditions for an extended period of
time.
If there is any doubt, please return the device to the manufacturer for repair or maintenance.
12. Customers must not attempt to alter or repair the device themselves. Please return
the device to the manufacturer for any repair or maintenance.
13. Any operation not included in the following instructions or outside the specifications
must not be attempted.
1.2. Specific safety instructions
The Low-Pressure Controller CPC2000 is used for testing and calibrating pressure sensors.
Always observe the operating requirements —particularly the permissible supply voltage—
indicated on the product label and in the ―11 Specifications‖ section of this manual. The
instrument may only be handled as indicated in this manual. The manufacturer is not liable
for damages caused by improper use or failure to follow these instructions. Violations of this
type render all warranty claims null and void.
1.3. Shipping, assembly, electrical connection and startup
Do not close the pressure ports when shipping, as changes in barometric pressure
could damage instruments with low measuring ranges.
Only technical personnel who are appropriately trained and authorized by the
operator of the facility may assemble the instrument and set up its electrical
connections.
Pressurized air or breath is not to be used for performance tests, as this could
damage instruments with low measurement ranges.
Measurement errors may occur if the instrument is not kept protected from sunlight.
Specific safety precautions are given in the individual sections of this manual.

into the sub menu via the key SELECT. The following sub menu items are available.
2.8.1. Range
It is possible to change the controller end value of the sensor range to protect device under
test with smaller pressure ranges.
2.8.2. Unit
This feature allows the operator to select the units used for displaying pressures. Certain
measurement ranges cannot be displayed meaningfully in some units, in which case the
units in question are not available. The following units may be selected:
Pa, kPa, hPa
bar, mbar
psi, inH2O, inHg, mmHg
Torr
2.8.3. Steps

step size.
Info: Basic information about the instrument and manufacturer.
2.9. Button LEAK
The test feature blocks both pressure ports, allowing the operator to measure a
drop in pressure on the test object itself. (This feature is only in the control mode
available)
2.10. Button ZERO
Button for manual zero adjustment of the integrated sensor.
By external influences such as temperature, location, or ambient pressure the zero
point of the device can move. During the zero-point adjustment, the unit
automatically determines this shift, and expects them into the displayed pressure.
The zero adjustment requires a switch of the internal valves, which is not possible without a
pressure drop. If this interferes with the use case of the automatic zero point adjustment can
be switched off.
2.11. Overpressure protection
It is not allowed to override the permissible overpressure safety: CPC2000-1mbar /
CPC2000-10mbar / CPC2000-100mbar have a 5 time overpressure safety; CPC2000-
1000mbar has a 2 time overpressure safety.
