3.1.5 Power supply of the CPX terminal
Note
Check within the framework of your EMERGENCY STOP
concept 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).
Note
When supplying power to CPX terminals with connected
pneumatics:
· 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:
− MPA pneumatics: ±25%,
− VTSA pneumatics: ±10%
− Midi/Maxi pneumatics:±10%
− CPA pneumatics: +10/−15% or
− CPX−CP interface: +10/−15%.
Power is supplied to the CPX terminal (in the form of operat
ing and load voltages) via supplies in the interlinking blocks
(see section1.1.3 for an overview of the supplies). These con
duct the operating and load voltages to the neighbouring
modules.
