If the operating status of the pneumatic system differs from
the desired pneumatic operating status, the following condi
tions are probably not fulfilled:
Prerequisites
Tubing connected with care
Regulated auxiliary pilot air
Sufficient pressure supply via
pressure supply points
Non−return valves in common
exhaust line
Externally supplied regulated
auxiliary pilot air (3...7 bar)
Guarantees the controller
function for the external auxiliary
pilot air despite the complete
supply being switched off
If there are control signals, the
auxiliary pilot air must be at full
pressure immediately after being
switched on.
Remarks
Exhaust the valve terminal
additionally with a large surface
mounted silencer in the right−hand
end plate (3/5, 82/84)
This applies when several systems
with centrally ducted exhaust are
used
Controller can only be operated with
pressure (between 3...7 bar)
The controller regulates the auxiliary
pilot air of all the valve sub−bases on
a valve terminal
