5.1 Check the instrument
Prior to commissioning, the pressure switch must be subjected to a visual inspection.
Leaking fluid is indicative of damage.
■
Only use the pressure switch if it is in perfect condition with respect to safety.
■
Check the diaphragm for any visible damage, since this is a safety-relevant component.
■
5.2 Requirements for mounting point
The mounting point must meet the following conditions:
Protected from weather influences.
■
With a high ambient temperature and a high UV irradiation, the pressure switch must be installed with additional
■
covering in order to avoid damage to the digital indicator and buttons.
Sealing faces are clean and undamaged.
■
Sufficient space for a safe electrical installation.
■
For information on tapped holes and welding sockets, see Technical information IN 00.14 at www.wika.com.
■
Permissible ambient and medium temperatures remain within the performance limits. Consider possible restrictions
■
on the ambient temperature range caused by mating connector used.
