Wiring Concepts Of The Valve System - Emerson AVENTICS AV Notice D'instruction

The "Electrical supply plate" module (5) interrupts the incoming supply volt-
age UA. The supply voltage of this module is used for all valves located to the
right of the electrical supply plate. The "Electrical supply plate" module can be
used several times in the valve area.
The voltage UL is galvanically isolated from the voltage UA in the valve system.

3.9 Wiring concepts of the valve system

The 3 figures below show the various wiring concepts of the valve system.
The following applies to all 3 representations:
• The power supply at the bus coupler (K1) for UL and UA is provided via plug
X1S1.
• The supply of the safe supply voltage for the valves is always made via the
connection of the additional electrical supply plate (X1S2) of the valves.
For the following wiring concepts, the equipment with the reference
designations based on EN 81346 is used. The examples only show the
relevant section of the power supply and are not complete. For the ap-
plication within a machine, additional equipment is necessary.
See g Fig. 14. In the wiring diagram, a common power pack (L01) is used for
both voltages UL and UA. The voltage for the valves at connection X1S2 is
switched off in 2 poles (i.e. UA+ and UA-) via the safety module.

In the following example, 2 separate power packs are used for both voltages UL
(L01) and UA (L02). The voltage for the valves at connection X1S2 is switched off
in 2 poles (i.e. UA+ and UA-) via the safety module.

In the following example, a shared power pack (L01) is used for both voltages UL
and UA. The voltage for the valves at connection X1S2 is switched off single-pole
