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