Safety Information - C2AI CPD Série Mode D'emploi

English English
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.

Safety information

General information
In order to ensure safe operation, the device may only be operated in accordance to the specifica-
tions stated in this operation 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 comp-
liance 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 and set-up 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, transformers and other sources of interference.
4. Fix plug screw only with closed cover
Mounting
• 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
Further information
Voltage version 0 ... 5, 0 ... 10V
Please consider a possible fall of voltage in the GND supply especially in connection with the use of
the display and display lighting. Recommended is a short cable with a large crosssection.
To prevent over-heating the display lighting swtiches off automatically with higher temperatures.
