Installation, wirings and start-up procedures must be performed according to the general prescriptions shown in table F003 and inthe installation notes supplied with relevant electrical signals of the valve ( monitor signals) must not be directly used to activate safety functions or components, as prescribed bythe European standards (Safety requirements of fluid technology systems and components-hydraulics, EN-982).

6 3 GENERAL NOTES(1) Average response time value; the pressure variation in consequence of a modification of the reference input signal to the valve is affectedby the stiffness of the hydraulic circuit: greater is the stiffness of the circuit, faster is the dynamic response, see section 12 Notes: above performance data refer to valves coupled with atos electronic drivers, see section .
