ELETTROMAGNETIC COMPATIBILITY
Atos electronic drivers and proportional valves are designed according to the 2004/108/CE Directive (Electromagnetic Compatibility) and according
to EN 50081-2 (Emission) and EN 50082-2 (Immunity) standards. The electromagnetic compatibility of electronic drivers is valid only for wirings
realized according to the typical electric connections shown in this technical table.
The device must be verified on the machine because the magnetic field may be different from the test conditions.
SAFETY
The electrical signals (for example reference signals, feedback and enable signal) of electronic drivers must not be used to realize safety condi-
tions of the machine. This is in accordance with the provisions of european directives (Safety requirements of fluid technology systems and com-
ponents-hydraulics, EN 982). Special attention must be payed to switch-on/switch-off of electronic drivers because they could produce uncontrol-
led movements of actuators operated by the proportional valves.
