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,
applicable 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.
The following guidelines apply to these devices:
ATEX Directive 2014/34/EU
EMC Directive 2014/30/EU
PED Directive 2014/68/EU
You find the complete EU Declaration of Conformity (document no. KE_044) at
www.labom.com.
1.4 ATEX Approval
If you purchased a device with ATEX approval, please refer to the accompanying
document XA_012 for ATEX-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…80 °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
Use gaskets, if required, that are suitable for the process connection and resistant to the
media.
There are no restrictions concerning the mounting position of the device.
Use the spanner flats to screw in the device.
Before starting operation, check the process connection carefully for leaks under pressure.
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.
output (2-wire) 4...20 mA (20...4 mA)
supply voltage UV= 10…30 VDC (Standard version)
UV= 20…27 VDC (Ex-design)
allowable load RB≤(UV- 10 V) / 20 mA
The transmitter is grounded via the process connection. Do not wire unconnected
terminals!

4 Operation
During operation, take care that the device remains within its intended pressure and
temperature ranges. No other monitoring is necessary.
Permissible media temperature: -20…120 °C
Permissible ambient temperature: -20…80 °C
4.1 Zero point correction
You can correct the zeropoint within ±10 %
of the nominal range with a magnet. To do
so, hold a permanent magnet (e.g. a pin
board magnet) to the position marked on
the pressure transmitter (letter in a circle)
for ½ to 2 ½ minutes after the power has
been switched on. A magnetic field applied
outside of this time period has no effect on
the setting.
Apply atmospheric pressure when
correcting the zero point.
The power must be switched off and on
before the zero point can be corrected
again.

4.2 Devices with Diaphragm Seal
Remove the protective cap or protective wrapping from the diaphragm only just before
installation 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.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.
In the event of any damage or defect the customer cannot replace or repair any
components or assemblies.

5 Disassembly
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
connections and removed devices.
Danger of injury

A
fter 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.
