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.
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 read zero. This kind of drift can be
corrected by zero point reset.
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.
