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 at
the left and right−hand end
plates (3/5, 82/84)
Faultless Non−return valves in common
exhaust line Applies in the case of several
systems with centrally
ducted exhaust
Two pressure zones Limiting the pressure zones
with a separator plate Subsequent conversion
possible
Vacuum operation/
low−pressure operation Externally supplied auxiliary
pilot air (3...8 bar) Controller can only be
operated with pressure
(between 3...8 bar)
Maximum vacuum (created by
vacuum generator) Sufficient compressed air
supply
Minimum supply pressure
No back pressure in exhaust
channel 3/5
·
The supply pressure must
not break down even when
several vacuum generators
are switched on at the same
time. If necessary, increase
the supply pressure.
·
Silencers must not generate
a high back pressure in ex
haust channel 3/5. If necess
ary, fit efficient silencers or
increase the supply pressure.
·
In order to prevent the ex
hausting of the valve affec
ting the generation of
vacuum, you must fit a separ
ator plate with Ident. code S
between the valve plate and
the vacuum generator plate.
