1 General Information
This document contains necessary information for the proper installation and use of this
device. In addition to this instruction, be sure to observe all statutory requirements, applica-
ble standards, the additional technical specifications on the accompanying data sheet (see
www.labom.com) as well as the specifications indicated on the type plate.
1.1 General Safety Notes
The installation, set up, service or disassembly of this device must only be done by trained,
qualified personnel using suitable equipment and authorized to do so.
Warning
Media can escape if unsuitable devices are used or if the installation is not
correct.
Danger of severe injury or damage
Ensure that the device is suitable for the process and undamaged.
1.2 Intended Use
The device is intended to measure pressure of gases, vapors and liquids as specified in the
data sheet.
1.3 Conformity with EU Regulations
The CE-marking on the device certifies its compliance with the applicable EU Directives for
placing products on the market within the European Union.
You find the complete EU Declaration of Conformity (document no. KE_053) at www.la-
bom.com.
1.4 EX Approval
Devices of the type CK5xx1 are certified for use in explosive environments.
If you purchased a device with EX approval, please refer to the accompanying document
XA_009 for EX-relevant information.
2 Transportation and Storage
Store and transport the device only under clean and dry conditions preferably in the original
packaging. Avoid exposure to shocks and excessive vibrations.
Permissible storage temperature: -40…70 °C
3 Installation and Commissioning
Ensure that the device issuitable for the intended application with respect to pressure range,
overpressure limit, media compatibility, temperature range and process connection.
After the mechanical installation and electrical connection is completed, the device is ready
for operation as soon as the power supply is switched on.

3.1 Mechanical Installation
Before starting operation, check the process connection carefully for leaks under pressure.
Use gaskets, if required, that are suitable for the process connection and resistant to the
media.
3.2 Electrical Connection
Complete the mechanical installation before you connect the device electrically.
Set up all electrical connections while the voltage supply is switched off.

4 Operation
During operation, take care that the device remains within its intended pressure and tem-
perature ranges. No other monitoring is necessary.
Permissible media temperature: -40…100 °C
Permissible ambient temperature: -40…70 °C
4.1 Zero-point setting
Set the zero-point of the measuring device and the angle-of-rotation sensor separately.
4.1.1 Zero-point correction
Zero point deviations can occur due to the
mounting, the installation position or due to
the type and duration of use. Measuring de-
vices with micro control position pointers
can be corrected in a depressurised state
by means of the adjusting screw on the
pointer hub (see figure 1).
You can find further information about zero-
adjustment of pressure gauge with micro
adjustment pointer in the document TA_029
on www.labom.com.

4.1.2 Adjusting the angle-of-rotation sensor
For adjustable devices the adjustment re-
quires to apply the lower limit pressure re-
spectively the upper limit pressure to the de-
vice. Bring the enclosed or another magnet
in the alignment position (see picture) to ad-
just accordingly. After approx. 2 seconds a
light signal in the scale acknowledges the
adjustment of the measurement range
begin and/or the adjusted range. The ad-
justment is possible within a tolerance of ap-
prox. ± 5 % F.S. Any settings that differ from
this will not be accepted.

4.2 Devices with Diaphragm Seal
Remove the protective cap or protective wrapping from the diaphragm only just before in-
stallation to prevent contamination or damage.
The diaphragm must not be touched. Do not place the device on its diaphragm. Even small
scratches or deformations may negatively influence the zero point or other characteristics
of the device.
Pressure transmitter and diaphragm seal are a closed system that must not be separated.
You can find further information about diaphragm seals in the document TA_031 on www.la-
bom.com.
4.3 Maintenance / Service
When properly installed in accordance with applicable specifications, this device is mainte-
nance-free. However, we recommend an annual recalibration of the device.

5 Disassembly
When measuring hot media, make sure that the device has cooled down prior to any dis-
mounting or wear appropriate protective clothing to avoid burns.
Switch off the power supply to the device before disconnecting the electrical connections.
Once this is done, the device may be mechanically removed.
Warning
Opening pressurized lines might cause severe injuries.
Danger of severe injuries or damage
Relieve the process pressure before attempting to remove the device. Shut
off the pressure supply for all feed lines to the device and relieve the pres-
sure in them.
Warning
Hazardous deposits and residues might remain on opened process connec-
tions and removed devices.
Danger of injury
After the device has been removed, seal off the measuring point and mark
the open process connection accordingly. Consider a possible danger due
to residues when handling the removed device.
