Connection of external Terminal type AXG-1A(E)
An external terminal is required for starting-up and setting-up versions that do not have an integrated
terminal.
•
Model AXG-1A, Part-No. 349034 for wall mounting
•
Model AXG-1AE, Part-No. 349008 for panel mounting
Connection Terminal Type
AXG-1A(E)
The connection is made via a 4-strand line at the terminals of plug (D-, D+, GND and
+24 V).
e.g., telephone
fl
ex e.g. J-Y (St) Y 2x2x0.6 (or similar), maximum line length ca. 250 m.
- Voltage supply: Terminal

(RS 485)
If the Modbus
®
interface is used for network a
“
Z-Modul-A
”
(Part.-No. 380054) is necessary to use an
external terminal at the same time.

Digital inputs (D1, D2)
Various functions can be allocated to the digital inputs
“
D1
”
and
“
D2
”
(

fl
oating contacts (a low voltage of ca. 24 V DC is
connected).
Danger due to electric current
Never apply line voltage to the digital input!
It is not permissible to connect inputs of several devices to each other!

Relay outputs (K1, K2)
Various functions can be allocated to the relay outputs

Communication
5.14.1
Networking via MODBUS-RTU
The device comes equipped with a RS-485 interface for networking via MODBUS. Conntection at:
“
A
(D+)
”
,
“
B (D-)
”
and
“
GND
”
.
The address must be set in the
“
IO Setup
”
menu.
Information
A maximum of 64 members can be directly connected to one another, and another 63 members via a
repeater.
5.14.2
RS-485 - network design and interface parameter
Please ensure the correct connection; i.e. "A (D+)" must always be connected to "A (D+)" of the next
devices. The same applies to "B (D-)" .
In addition, a "GND" connection must be established, as dissimilar potential (over 10 V!) will lead to
the destruction of the RS-485 interface (e.g. lightning).
