A fault monitoring module is only required once in a group.
There is no need for individual evaluation of up to 115
connected Mini Analog Pro signal conditioners.
For the behavior of the fault monitoring contact for the different DIP
switch configurations, please refer to the corresponding table.

6.8 Current measurement

The device allows current measurement without disconnection of
the conductors by means of integrated test disconnect terminals.
Test sockets which support current measurement are
marked TI+ or TI-.
For the current measurement, use 2 mm probe tips of the
type Fluke TL75-1 or probe tips with a comparable tip shape.

Furthermore, individual circuits can be specifically

disconnected, e.g. for commissioning.
You can set the isolating position by turning the integrated
spindle screw through 180°. The isolating position is
indicated by the marking on the plugs.

7.2 Configuration via software

Use the IFS-USB-PROG-ADAPTER

programming adapter (Order No.: 2811271),
the NFC-USB-PROG-ADAPTER (Order No.:
2900013), or the IFS-BT-PROG-ADAPTER
(Order No.: 2905872) for connection of the
device and PC.

Figure 8 Programming connection

In addition to DIP switch settings, software configuration

offers enhanced setting options and a monitoring function
for maintenance purposes.
The following free software solutions are available for you to
download from the Internet.
– ANALOG-CONF standard software
– FDT/DTM solutions: FDT frame application and DTM
packages

7.3 Configuration via MINI Analog Pro app

In addition to DIP switch settings, app configuration offers
enhanced setting options.
Using the MINI Analog Pro Smartphone app via the NFC
interface of your Smartphone you can configure the module
without an additional programming adapter or cables.
Alternatively, you can use the Bluetooth programming
adapter (Order No. 2905872).

Switching points must not exceed the maximum measuring range.

Switching behavior
Function of the switching output: signal high level after the
switching point is exceeded; before this signal low level.

8.2 Monitoring
A monitoring function can be used with the software or app
solutions. This means that you can display and note down
current measured values via the software interface.

8.3 Limiting behavior of the analog output

In some applications it is important that the standard signal
at the output remains within its limits. In the case of a
4 mA  20 mA signal, for example, this means that the
signal does not drop below 4 mA or exceed 20 mA.
You can set this behavior under “Error signaling > Analog
output > Limitation”. The best way to do this is via the
software or app solutions.
If you configure the device via the DIP switches, you must
select the combination with which the error signaling outputs
the measuring range starting value as the value for underrange
and the measuring range final value as the value for overrange.
