Pressure Sensors Series PS
4 Installation and setup instructions
■
Even though the device is excellently protected against electro-magnetic
interference, installation and cabling must be carried out correctly to
ensure interference immunity.
■
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 broadcasting stations.
■
Signal lines should be installed in mounting cabinets and as far away as
possible from contactors, control relays, transformers and other sources of
interference.
■
The housing surface may not be painted or coated, because the reference
port could be clogged.
5 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 see chapter 11.2,
parameter CoF).
■
The read direction of the on-site display can be rotated via software by
180° (see chapter 11.2, parameter diS).
