Mechanical mounting (VSX models)
DIMENSIONS OF THE ACTUATOR
•
The actuator is set to its closed position in our factory.
•
Possible fixations : F07 (4xM8 with Ø70) and F10 (4xM10 with Ø102), star 22, depth 24mm.
•
Do not mount the actuator « upside down ».
•
Necessary height above the valve for the mounting of the actuator : H=360mm.
•
Do not mount the actuator less than 30 cm of a electromagnetic disturbances source.
EMERGENCY MANUAL OVERRIDE AND MECHANICAL STOPS SETTING
The actuator operates in electric priority. Ensure that the power supply is cut off prior to manually operation. No declutching is
required, the hand wheel has simply to be turned (appendix p.32 mark 9).
The end mechanical stops are preset to 90° and stuck (Tubetanche Loctite 577 or equivalent). It is posible to adjust then by
moving the 2 screws M8 (appendix p.32 mark 17) but you need to stick them again in order to ensure a proper sealing.
MOUNTING / DEMOUNTING OF THE COVER AND POSITION INDICATOR
For the wiring and setting of the actuator, it is necessary to remove the cover.
•
Mounting of the cover (appendix p.32 mark 2) : make sure that the seal ring (appendix p.32 mark 7) is correctly placed in its
position, mount the cover and tighten the 4 screws M6 (appendix p.32 mark 3, torque : max. 6Nm).
•
Mounting of the position indicator (appendix p.326 mark 1) : mount the seal ring and the indicator then the window with the
4 screws M4.
