Alternatively or supplementary to the inscription labels
attached to sub−bases, inscription labels with large surface
areas can be attached to the pneumatic interface.
Information about corresponding accessories can be found
in the Festo Catalogue (see www.festo.com\catalogue).
The manual override (MO) enables the valve to be actuated
when not electrically activated or energised. You only need
to switch on the compressed air supply. You should use the
manual override especially when commissioning the pneu
matic system, in order to check the function and operation
of the valve or the valve−actuator combination.
The valve is activated by pushing the manual override.
On release of the manual override the spring−loaded
valve switches automatically from the switch position to
the normally open position.
By turning the manual override clockwise the switch position
can be detented. It remains actuated until it is reset by hand.
These basic functions of the manual override can be changed
by installing a corresponding manual override cover cap:
With a cover for manual override, code: N, locking is pre
vented. The manual override can then only be operated by
non−detenting.
With a cover for manual override, code: V, the manual over
ride can be safeguarded against undesired operation
The operation of the manual override is described in
Chapter 4.2.
