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" can cause unexpected reactions
of the valve terminal.
S Make sure that these switch-on test pulses are reliably
suppressed or switched off.
Use only a 4-pin M12 socket for the power supply and con-
nect this only to the connection for the power supply (see
Fig. 1/1).
The current consumption depends on the type of valve ter-
minal. Please refer to the "Pneumatics manual, P.BE-CPV-.."
and the previous chapter for the values.
When connecting the 24 V load voltage (pin 2), observe the
following:
S
Observe the tolerance (20.4 V DC ... 26.4 V). Check the
24 V load voltage of the valves while your system is oper-
ating.
Caution
Protect the load voltage of the CPV valve coils externally
with a fuse max. 2 A.
In this way you can avoid functional damage to the CPV
Direct in the event of a short circuit.
