Starting up via manual override

The manual override is ideal for starting up the device and system. The manual override operates without
the device being connected to the power supply and enables manual switching of the valves.
The manual overrides are marked differently depending on the circuit function (CF) of the valves:
CF C, CF Z, CF H (with CF H only 1 manual override):
Marking Impact of the switched manual override

14 Supply duct 1 connected to working port 4
CF D:
Marking Impact of the switched manual override
10 (12) Connection from supply duct 1 to working port 2 interrupted
10 (14) Connection from supply duct 1 to working port 4 interrupted

The manual override provides both spring-return and latching action as standard.
Spring return:
If the slide mechanism is moved to an initial resistance, the manual override returns to the unswitched state
once it is released.
Latching:
If the resistance is exceeded, the manual override remains in the switched state after being released. Man-
ually push the slide mechanism back over the locking point to reset the manual override to the unswitched
state.
