Safety notes
Operational safety
The device is safely built and tested according to state-of-the-art technology and has left the factory in perfect
condition as regards technical safety.
The device meets the legal requirements of all relevant EC directives. This is confirmed by attaching the CE
mark.
Installation, connection, commissioning, operation
Installation, electrical connection, commissioning and operation of the device must be made by a qualified and
authorized expert according to the information’s in this technical manual and the relevant standards and rules.
This expert must have read and understood this technical manual and especially the safety notes.
The device may only be used within the permitted operation limits that are listed in this technical manual. Every
use besides these limits as agreed can lead to serious dangers.
The materials of the device must be checked for compatibility with the respective application requirements
(contacting materials, process temperature) before use. An unsuitable material can lead to damage, abnormal
behavior or destruction of the device and to the resulting dangers.
The sensors may not be used as sole device for prevention of dangerous conditions in machines and plants.
Using the device in a manner that does not fall within the scope of its intended use, disregarding this
instruction, using under-qualified personnel, or making unauthorized alterations releases the manufacturer from
liability for any resulting damage. This renders the manufacturer‘s warranty null and void.
Safety notes for electrical operating supplies
for explosive hazardous areas
If a device is installed and operated in explosive hazardous areas, the general Ex construction standards
(EN/IEC 60079-14, VDE 0165), these safety notes and the enclosed EC conformity certificate must be
observed.
The installation of explosive hazardous systems must be carried out principally by specialist staff.
The device meets the classification
II 1 G Ex ia IIB/IIC T6...T1 Ga resp.
II 1/2 G Ex ia IIB/IIC T6...T1 Ga/Gb resp.
II 2 G Ex ib IIB/IIC
T6…T1 Gb
The devices are conceived for detection of limit values in explosive hazardous areas.
The measured medium may also be combustible liquids.
The permitted operating temperatures and pressures are type and variant dependent and can be found in this
technical manual.
For applications, which require devices of category 1 or category 1/2, the process pressure and temperature
range of the media has to be between 0,8 bar and 1,1 bar and between -20 °C and 60 °C.
If a device is mounted in the separation wall to the hazardous area that requires devices of category 1, the
process connections have to be designed in such a way, that they are sufficiently tight according to
EN/IEC 60079-14 section 4.6.
The operating device may only remain in the zone when connected to an evaluation device and connected to
the potential compensation.
The device is earthen for safe technical function. Provide sufficient potential compensation along the complete
cable way. Install the intrinsically safe circuit earth free.
At variants of the devices with chargeable plastic parts (e.g. connection housing, isolation), a warning marking
points out to the safety measures, that must be applied because of the electrostatic charging in operation and
especially in the case of maintenance activities.
