Electrical connection

The multiple plug connector I for the valve controls is located on
the left end plate.
There are two controls (multiple plug connector pins)
permanently assigned to valve solenoids 12 and 14 for each
valve position.
W
Only solenoid 14 must be connected in 5/2 valves with
spring or air-actuated return. The second control for
solenoid 12 remains unused.
W
The following are assigned to each other in the 3/2 valve
units:
– Solenoid 14 and pneumatic connection 4
– Solenoid 12 and pneumatic connection 2
24 V DC supply voltage with electrical isolation via power
supply unit according to DIN EN 60742, classification
VDE 0051.
All GND pins are bridged in the multiple plug connector.
When wiring, ensure that at least 2 GND pins are connected
in order to be able to accept the total current from all valve
solenoids (20 mA per solenoid).
Solenoid control must be protected by an external fuse.
The permissible current load of a 1 A per multiple plug
connector pin may not be exceeded!
The crimped contact connections fit wire cross-sections of
2
0.14 ... 0.56 mm .
Please only use multiple-strand cables with an external
insulation diameter from 0.9 to 15.5 mm; use the
appropriate mating plug sealing element to ensure that the
IP 65 degree of protection and the strain relief are
guaranteed.
