If the operating status of the pneumatic system deviates from
the desired pneumatic operating status, the following condi-
tions are probably not fulfilled:
Condition
– Tubing connected with care
– Regulated pilot air supply
Sufficient pressure supply via
pressure supply points
Non-return valves in common
exhaust line
Separately supplied closed-loop
controlled pilot air (3 ... 7 bar)
Guaranteeing the controller
function for the pilot air, despite
complete supply being switched
off
The external pilot air must be at
full pressure immediately after
being switched on
Remarks
Exhaust the valve terminal
additionally in the right-hand end
plate via a large surface-mounted
silencer (3/5, 82/84)
Applies if several systems with
centrally ducted exhaust are used
Controller can only be operated
with pressure (between 3 ... 7 bar)
The controller regulates the pilot
air of all the valve plates on a valve
terminal
