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 pneumatic
operating status
Requirement
Description
Zero leakage
Tubing connected with care
Regulated pilot air supply
Fast reaction
Sufficient pressure supply by means
of pressure supply modules
Exhaust the valve terminal MPA−L
via all the exhaust plates or via the
flat plate silencer
Trouble−free
Non−return valves in common ex
haust line
This applies when several systems
with centrally ducted exhaust air are
used
Two or more pressure
zones
Limiting the pressure zones by
means of separating seals with
blocked channels
Appropriate number of pneu
matic air supply plates for
supplying the different pressure
zones.
Subsequent conversion possible
(see Chapter 5)
Vacuum or low−pres
sure operation
Externally supplied regulated pilot
air supply (3 ... 8 bar)
Vacuum/low−pressure operation not
with 3/2−way valves
EMERGENCY STOP of
pressure zones
Guaranteeing the controller function
for the pilot air supply despite the
overall supply being switched off
The controller regulates the pilot air
supply to all the valve plates on a
valve terminal MPA−L
Slow start−up after
EMERGENCY STOP
If control signals are present, the pi
lot air supply must have a pressure
of 3 ... 8 bar immediately after being
switched on
