Control Top with Cap
According to protection class IP67 and/or 69k (EN 60529) the control top T.VIS
E-20 is suitable for use in this design and if the electrical and pneumatic
connections are installed correctly.
Observe the general instructions regarding ESD protection.
3.2.5
Safety Air Exhaust/Installation Position
To provide protection against excess pressure which can build up in the inside of
the control top, a vent plug (E2) is fitted in the base.
In operating mode, the exhaust air from the lifting actuators is discharged via this
vent plug. In the unlikely event of a damaged solenoid valve or in case of sealing
problems, pressure relief is ensured.
