Before operating refer to the instruction manual!
Any person entrusted with the set-up or operation of the device, must have read and understood this operation
manual, in particular all safety notes.The guarantee is invalid in respect of damage resulting from a failure to
follow the instructions, incorrect handling or inappropriate use. We accept no responsibility for consequential damages
resulting from any of the above.
General information
In order to ensure safe operation, the device may only be operated in accordance to the specifications stated in this opera-
tion manual. Futhermore, all legal and safety regulations concerning this specific application should be observed.This also
applies to the use of accessories.
Correct use to the intended purpose
These devices are designed for indication and monitoring of process variables. All other forms of usage do not comply with
the intended purpose. These sensors may not be used solely as means for prevention of dangerous machine and system
conditions. Machines and systems must be constructed in such a way, that faulty states cannot lead to a dangerous situation
for the operating staff (e.g. due to independent limit switches, mechanical interlocking devices, etc.).
Qualified staff
The devices may only be installed, connected, set-up and operated by qualified staff and in compliance with the
technical specifications. Qualified staff is defined as persons, who are familiar with set-up, mounting, start-up and
operation of this device and who possess a recognized degree or certificate of appropriate professional training.
Remaining hazards
These sensors employ state-of-the-art technology and are safe to operate. However, if they are installed and operated by
unqualified staff, an element of risk remains.
In this manual the remaining risks are marked by the following symbol:
This symbol is posted where there is a risk of serious injury or death or the damage of material and property,
if the warning is ignored
Installation instructions
Even though the device is excellently protected against electro-magnetic interference, installation and cabling must be carried
out correctly to ensure interference immunity.
1. Use shielded cables for the signal and control lines with the connecting lead of the screen being kept as short as possible.
The connection point of the shielding depends on the existing connection conditions.
2. Never route signal and control cables together with the trunk line or feeder cables of motors, cylinder coils, rectifiers
etc. The cables must be routed in conductive and grounded cable conduits. This applies especially to long-distance
cables, or environments in which the cables are exposed to strong radio waves from broad casting stations.
3. Signal lines should be installed in mounting cabinets and as far away as possible from contactors, control relays, trans
formers and other sources of interference.
Montage
• Prior to mounting or removing the sensor it must be verified that the system is depressurized.
• Do not mount sensors in locations subject to high pressure pulses.
• Significant thermal changes in the sensor environment can lead to a zero shift. As a result, the measuring value displayed
in a depressurized state will not read zero. This kind of drift can be corrected by zero point reset.
• Supply from SELV or class 2 source limited energy circuit 15 W or less
• Use Copper conductors only
