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, appli-
cable 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_019) at
www.labom.com.
1.4 ATEX Approval
Devices of the type CK5xx1 are certified for use in explosive environments.
If you purchased a device with ATEX approval, please refer to the accompanying docu-
ment XA_009 for ATEX-relevant information.
2 Transportation and Storage
Store and transport the device only under clean and dry conditions preferably in the origi-
nal packaging. Avoid exposure to shocks and excessive vibrations.
Permissible storage temperature: -40…70 °C
3 Installation and Commissioning
Ensure that the device is suitable 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.
Figure 1: Versions of the electrical connection
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
Small measuring errors or deviations
caused by difference in level between pres-
sure gauge and point of measurement can
be corrected on measuring devices with
micro control position pointers. To do so
turn the adjusting screw on the pointer hub
(see figure 2).
Similarly, a displacement of the zero point
caused by use and long service life can be
corrected if necessary.

4.1.2 Adjusting the angle-of-rotation sensor
For adjustable devices the adjustement re-
quires to apply the lower limit pressure re-
spectively the upper limit pressure to the
device. Bring the enclosed or another mag-
net in the alignment position (see picture) to
adjust 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 adjustment
is possible within a tolerance of approx. ± 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 charac-
teristics 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.labom.com.
4.3 Maintenance / Service
When properly installed in accordance with applicable specifications, this device is
maintenance-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
pressure 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 dan-
ger due to residues when handling the removed device.
