Warning
If the valve terminal is supplied with load voltage via an
output of a "safety I/O module", switch-on test pulses of
the "safety I/O module" may lead to unexpected reactions
of the valve terminal.
Make sure that switch-on test pulses are reliably
•
suppressed or switched off.
Current consumption depends on the type of valve terminal.
Please refer to the "Pneumatics Manual, P.BE-CPV-..." and the
previous section for the values.
Connect the power supply to the 4-pin M12 plug
•
(Fig. 1/1).
Observe the tolerance when connecting the 24 V load
•
voltage at pin 2: 20.4 ... 26.4 V DC. Check the 24 V operat-
ing voltage of the valves whilst the system is operating.
Caution
Protect the load voltage of the CPV valve coils with a
max. 2 A external fuse.
In this way you can avoid functional damage to the
CPV Direct in the event of a short circuit.
