Fieldbus Connection; Power Supply; Led - Emerson AVENTICS AES Serie Systembeschreibung

The tightening torque for the M4x0.7 nut (SW7) on the ground screw is 1.25 Nm
+0.25.

Fieldbus connection

The X7E1 (5) and X7E2 (6) fieldbus connections are designed as integrated M12
sockets, female, 4-pin, D-coded.
See Table 6 for the pin assignments for the fieldbus connections. The view
u
shown displays the device connections.

The AES series bus coupler for PROFINET IO has a 100 Mbit full duplex 2-port
switch, so that several PROFINET IO devices can be connected in series. As a re-
sult, the controller can be connected to either fieldbus connection X7E1 or X7E2.
Both fieldbus connections are identical.
Fieldbus cable
Danger caused by incorrectly assembled or damaged cables!
The bus coupler may be damaged.
Only use shielded and tested cables.
u
Faulty wiring!
Faulty wiring can lead to malfunctions as well as damage to the network.
1. Comply with the PROFINET IO specifications.
2. Only a cable that meets the fieldbus specifications as well as the connection
speed and length requirements should be used.
3. In order to assure both the protection class and the required strain relief,
the cable and plug assembly must be done professionally and in accor-
dance with the assembly instructions.
4. Never connect the two fieldbus connections X7E1 and X7E2 to the same
switch/hub.
5. Make sure that you do not create a ring topology without a ring master.

Power supply

Electric shock due to incorrect power pack!
Danger of injury!
1. Only use the following power supply for the bus coupler:
- 24 V DC SELV or PELV circuits, each with a DC fuse that can interrupt a cur-
rent of 6.67 A within max. 120 s, or
- 24 V DC circuits meeting the requirements for energy-limited circuits as
described in section 9.4 of UL standard UL 61010-1, third edition, or
- 24 V DC circuits meeting the requirements for power-limited power
sources in accordance with section 2.5 of UL standard UL 60950-1, second
edition, or
- 24 V DC circuits meeting the requirements of NEC Class II in accordance
with UL standard UL 1310.
2. Make sure that the power supply of the power pack is always less than
300 V AC (outer conductor – neutral wire).
The X1S power supply connection (7) is an M12 plug, male, 4-pin, A-coded.
See Table 7 for the pin assignments for the power supply. The view shown dis-
u
plays the device connections.

• The voltage tolerance for the electronic components is 24 V DC ±25%.
• The voltage tolerance for the actuator voltage is 24 V DC ±10%.
• The maximum current for both power supplies is 4 A.
• The power supplies are equipped with internal electrical isolation.
Functional earth connection
8
To discharge the EMC interferences, connect the FE connection (8) on the bus
u
coupler via a low-impedance line to functional earth.
The cable cross section must be designed according to the application.

4.1.2 LED

The bus coupler has 6 LEDs.
The table below describes the functions of the LEDs. For a comprehensive de-
scription of the LEDs, see "LED Diagnosis on the Bus Coupler".
