Ventilation on the valves
Connection R may never be closed since this will cause
damage to the valves!
O
Ensure sufficient ventilation via channels 3, 5 and R in
order to avoid air accumulation or valve damage.
The air supply and exhaust connections in the valve system
are available on each of the two end plates! Connect the
supply and exhaust air lines to both sides.
With the help of the separators between the subplates, several
pressure zones are possible.
The valves direct the air to the pneumatic drives. The connection
is made via the valve's subplate (plate connection).
Each valve has a manual override. Depending on the version,
'turn and detent' (yellow knob) or 'turn' (red knob). In both cases
it is activated by a turning motion (DO NOT push!).
Solenoid control takes place via the multiple plug connector.
The multiple plug connector pins are fed through all subplates
from the end plate to provide a clear assignment. The current-
carrying solenoids are displayed by a yellow LED on the valve.
Valve assignment is clear as it is marked with 14 and 12.
