For EN 61000-4-3 Radiated RF Immunity, the controller meets Performance Criteria B. In environments where severe radio-frequency
interference (RFI) is present, the controller may reboot/restart. If this occurs, the controller should be relocated away from the electromagnetic
interference (EMI) source.
*Class A equipment: Equipment suitable for use in establishments other than domestic, and those directly connected to a low voltage
(100-240 VAC) power supply network which supplies buildings used for domestic purposes.
2.3 Intended Use
The Walchem Intuition-6 is a microprocessor-based measuring and control instrument used to measure water quality param-
eters and other process variables in a wide range of water and wastewater treatment applications. Operating the instrument
in any way other than as described in these instructions may compromise the safety and function of the measuring system
and is therefore impermissible. Electrical connection work and maintenance work may only be carried out by qualified per
-
sonnel. The manufacturer is not liable for damage caused by improper or non-designated use.
