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 temperature in technical processes 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_002 for GA220x or
KE_005 for GA221x) at www.labom.com.
1.4 EX Approval
Devices of the type GA2201 and GA2211 are certified for use in explosive environments.
If you purchased a device with EX approval, please refer to the accompanying document
XA_004 for GA2201 or XA_002 for GA2211 for EX-relevant information and hints.
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…100 °C
When supplied with a transmitter the max. permissible storage temperature is reduced to
85 °C.
3 Installation and Commissioning
Ensure that the device is suitable for the intended application with respect to temperature
range, pressure range, medium compatibility 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.
The process connection determines the permissible process pressure. Operating the de-
vice beyond its nominal pressure limit, e.g. clamp-connections, requires specially designed
and approved mounting elements.
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.

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: -20…200 °C
Permissible ambient temperature: -40…100 °C
When supplied with a transmitter, the permissible ambient temperature is reduced to 85°C.
Restricted ambient conditions may apply in explosion protected environments (see
XA_004 for GA2201 or XA_002 for GA2211).
4.1 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 a device malfunction, you can only replace the measuring insert respective-
ly the head transmitter.
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.
