Make sure that no moisture can penetrate into the device! The seals and sealing
surfaces must not get dirty; this is because any contamination may, depending on
the particular application or location, lead to a reduction in the level of protection
and hence to failure of the device or irreparable damage to the device!
5. HART communication
An additional signal complying with the HART
logue output signal. Configuration of the device can be carried out with the aid of a

HART
communication device. We would recommend our CIS 150 programming kit
(available as an accessory) for this purpose.
In order to ensure trouble-free operation, the following specifications should be taken into
account:
