Operating states of the pneumatic system
The following conditions should be fulfilled, in order that the
desired pneumatic operating states listed below can be
achieved:
Desired pneuma
tic operating sta
tus
Prerequisites
Remarks
free of leakage
tubing connected with care
regulated auxiliary pilot air
fast reaction
sufficient pressure supply via pres
sure supply points
·
Exhaust the MPA valve terminal via
all the exhaust plates or via the
large surface−mounted silencer
faultless
non−return valves in common ex
haust line
This applies when several systems
with centrally ducted exhaust are
used
two or more pressure
zones
limiting the pressure zones by means
of sheet seals with blocked channels
subsequent conversion possible (see
chapter 5)
vacuum or low−pres
sure operation
externally supplied regulated auxi
liary pilot air (3 ... 8 bar)
controller can only be operated
with pressure (between 3 ... 8 bar)
vacuum/low−pressure operation
not with 3/2−way valves
EMERGENCY STOP of
pressure zones
guaranteeing the controller function
for the auxiliary pilot air despite the
complete supply being switched off
The controller regulates the auxiliary
pilot air of all the valve plates on an
MPA valve terminal
slow start−up after
EMERGENCY STOP
If there are control signals, the auxi
liary pilot air must have a pressure of
3 ... 8 bar immediately after being
switched on
