5. Electrical connections
5.1 Mains connection
Power from the mains is connected to terminals: PE, L1 and N. Here, it must be strictly observed that the mains voltage
lies within the allowable tolerance specifications (
)
General description: Technical data and nameplate affixed to the
side).
The supply voltage has to correspond to DIN EN 50160!
5.2 Signal cable (sensor cable)
Pay attention to sufficient distance from powerlines and motor wires
to prevent interferences
.
The control cables may not be longer than 30 m. Screened control cables must be used when the cable length is longer
than 20 m. When using a screened cable, the screen must be connected to the protective conductor at one end, i.e. only
at the control unit (as short and of as low an inductance as possible!).
5.3 Signal connection to analog inputs (Analog IN1, Analog IN2, ..)
The controller can work with 2 analog inputs, dependent on the type of signals must the appropriate terminals
connected.
Signal type
Connection terminals
Input 1 for Temperature sensor TF..
7 – 8 (to pay attention to no polarity)
Input 2 for Temperature sensor TF..
9 - 10 (to pay attention to no polarity)
Input 1 for 4..20mA (0..20mA)
11 - *12 (with Two-wire-technology)
Input 2 for 4..20mA (0..20mA)
13 - *14 (with Two-wire-technology
Input 1 for 0-10 V
15 (+) - 16 (GND)
Input 2 for 0-10 V
17 (+) - 18 (GND)
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 terminals „11“ (Input 1)
or “13“ (Input 2) the GND terminal is omitted.
For three wire technology connection to GND terminal is necessary (terminals 8,10,16,18)
The connection is independent of the programmed operating mode and from the sensor signal employed (
)
Presets of
the selected operating mode).
5.4 Output voltage 0-10 V (Analog OUT1 und Analog OUT2)
Analog output 1 (Analog OUT 1) is pre-programmed control outpute.g. for controlling a speed controller for fans.
Connection to terminal „A“ - „GND“ = Analog OUT (I
max
10 mA)
Analog output 2 (Analog OUT 2) is pre-programmed for contsant v10 V. E.g. supply for external potentiometer
connection to terminals „A2“ - „GND“ = Analog OUT 2 (I
max
10 mA)
Both 0-10 V analog outputs can be allocated with various functions (
)
IO Setup: Analog output A1 or A2).
5.5 Voltage supply for external devices (+24 V, GND)
A voltage supply is integrated for external devices, e.g., for a sensor.

20 %.
Max. load current 120 mA (for connection to an external AXG terminal minus ca. 50 mA)
During an overload or short-circuit (24 V
↔
GND), the control voltage (and thus the controller) is disconnected
(Multifuse). Automatic start after elimination of the cause of error
5.6 Relay outputs (K1, K2)
Various functions can be allocated to the relay outputs K1 and K2
(
)
IO Setup: Function and inversion of the relay outputs). Max. contact load 5A / 250 V AC
Connection of the floating contacts of relay K1 to the terminals 1, 2, 3
Connection of the floating contacts of relay K2 to the terminals 4, 5, 6
