Please note
Check within the framework of your EMERGENCY STOP
circuit, to ascertain the measures necessary for putting
your machine/system into a safe state in the event of an
EMERGENCY STOP (e.g. switching off the operating voltage
for the valves and output modules, switching off the com
pressed air).
Please note
With CPX terminals with Midi/Maxi pneumatics,
CPA pneumatics or CPX−CP interface:
Note that the lower tolerance range of the pneumatics
·
must be observed when the operating and load voltage
supplies are provided by a power unit.
Tolerance ranges:
Midi/Maxi pneumatics:
CPA pneumatics or CPX−CP interface: + 10 /− 15 %
MPA pneumatics:
Check the 24 V load voltage of the outputs while your system
is operating. Make sure that the load voltage of the outputs
lies within the permitted tolerance even during full−load oper
ation.
Recommendation:
Use a closed−loop power unit.
