3.10 Instructions for wiring

When using the aforementioned wiring concepts, the following instructions must
be observed:
1. Connect the valve system as shown in the 3 wiring concepts.
2. Make sure that the valves that are to be safely switched off are located down-
stream of the electrical supply plate.
3. Connect X1S2 via a 2-wire cable.
When using a cable with more than 2 cores, the following circumstances should
apply. See g Fig. 17:
• unused cores are connected to PE for EMC reasons
• no further voltage is present in the cable.
In case of single-pole disconnection of the voltage UA, the corresponding cable
must be laid cross-circuit proof.

UA-
The electrical supply plate (2) interrupts the UA supply to the valves. The preced-
ing valves (1) are supplied with the existing valve voltage. The downstream valves
(4) are supplied with the new valve voltage (6).
In the electrical supply plate, the new voltage from (6) is monitored for the limit
UAon.
When the voltage UA falls below the switch-on voltage UAon, the electrical sup-
ply plate sends the diagnostic bit UAon.
The pneumatic supply plate (3) interrupts the P supply (11) to the valves. The
preceding valves (1) are supplied with the existing compressed air. The down-
stream valves (4) are supplied with the new compressed air from (8).
In the pneumatic supply plate, the existing voltage UA is monitored for the limit
UAoff.
If the voltage UA falls below the switch-off voltage UAoff, the pneumatic supply
plate sends the diagnostic bit UAoff.
Monitoring of the voltage UA in the pneumatic supply plate is only
available if the valve terminal system has been configured accordingly.
The position of the diagnostic bits in the data area for the controllers
can be found in the corresponding descriptions for the AES series bus
couplers.

4 Conversion and repair

You may convert and repair the valve system as described in the system descrip-
tions of the bus coupler AES and valve driver AV.
