Mount attachment components

Fitting hoses to pressure compensation opening
For pressurising and depressurising the pressure compensation opening on ESBF-...-S1/F1:
• Tighten suitable screw connection into the thread 4.
• Connect a tube for the supply and exhaust of fresh air.
Alternatives to the routing of this hose:
– in a protected area (dust-free and dry)
– in a large expansion tank
– with low positive pressure (max. 0.2 bar) as sealing air.
Mount attachment component
• Place the centre of gravity of the attachment component, if
possible, centrally to the piston rod.
• Transmit as little torque as possible to the piston rod. Brace
against key surface 7. Excessively high torque can damage
the mechanism inside the cylinder (è Tab. 2).
• Mount the attachment component to the piston rod.
Do not exceed permitted level of transverse force (deflection of
piston rod è Appendix 13 characteristics curves).

To protect the end positions against uncontrolled overtravel:
• Check whether proximity sensors are necessary (as safety limit switches or hardware limit switches).
• Use appropriate proximity switches, sensor strips or mounting construction kits. Proximity switches
for polling the internal magnet must be arranged centrally on the flat profile surface
(è www.festo.com/catalogue).
• Use proximity sensors with normally-closed function. These protect the ESBF from overrunning of
the limit position if the proximity sensor cable is fractured.
• Avoid external influence caused by magnetic or ferritic parts in the vicinity of the proximity sensors.
