5.7 Signal connection or sensor connection to analog inputs (Analog In 1, Analog In 2)
The unit has 2-analog inputs:
•
E1 Analog In = terminals “ E1 ” / “ GND ” (Analog In 1)
•
E2 Analog In = terminals “ E2 ” / “ GND ” (Analog In 2)
Ensure correct polarity when connecting; a 24 V DC power supply is integrated for sensors. For
sensors in two-wire-technology (4 - 20 mA signal), the connection is made on the “ +24 V ” and “ E1 ” or
“ E2 ” terminals (the GND terminal is omitted). The connection is independent of the programmed
operating mode and from the sensor signal employed. Place the internal plug (jumper) for the external
default signal in the correct position factory setting 0 - 10 V ( F Jumper for Input signal).
Attention!
Never apply line voltage to analog inputs!
5.8 Output voltage 0 - 10 V (Analog Out)
The analogoutputs 0 - 10 V can be allocated with various functions ( F IO Setup: Analog output “ A ” ).
Connection to terminal “ A ” - “ GND ” = “ Analog Out ” (I
max
10 mA).
It is not permissible to connect outputs of several devices to each other!
5.9 Voltage supply for external devices (+24V, GND)
A voltage supply is integrated for external devices, e.g., for a sensor. “ +24 V ” Output voltage tolerance
+/- 20 %. Max. load current 120 mA (for connection to an external “ AXG.. ” terminal minus approx. 50
mA).
It is not permissible to connect outputs of several devices to each other!
During an overload or short-circuit (24 V - GND), the control voltage (and thus the device) is
disconnected . Automatic start after elimination of the cause of error.
5.10 Add-on module type Z-Modul-B Part-No. 380052
The expansion module can be retro  tted. This could be necessary if the analog and digital inputs and
outputs are not suf  cient for certain applications. The board is easy to install into the device and is
connected with the control device via a plug. Program the additional inputs and outputs in “ IO Setup ” .
Add-on module type Z-
Modul-B
•
1x analogue input 0-10 V (R
i
> 100 k Ω ) for external Set point

5.11 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  ex e.g. J-Y (St) Y 2x2x0.6 (or similar), maximum line length
ca. 250 m.
- Voltage supply: Terminal “ 24 V ” , “ GND ” , (I
max
, for terminal approx. 50 mA)
- Signal “ D+ ” and “ D- ” (RS 485)
