SICK FX3-MOC1 User Manual

NOTE
W
here encoders with two outputs are concerned, inputs A– and B– on the FX3-MOCx
must not remain open; they must be connected to 0V. In this case, the connection
must be as close as possible to the 0V encoder connection.

back connection boxes. Details:

5.4.9 Connecting analog sensors
Two analog sensors can be connected to the FX3-ANA0 analog input module in order
to measure a joint process variable. The analog input module has two analog inputs,
which are continually compared with one another.
Only sensors with a standardized current interface in accordance with EN61131-2
5.3.1 and with a signal strength of4 to 20mA can be connected and evaluated.
NOTICE
Ex
ceeding the limit values at the inputs
The device may be damaged if this is not observed.
►
Observe the limit values for the inputs (30V DC/30mA).
►
Only use suitable sensors.
The AI1 sensor input consists of pins 1+ and 1–. The AI2 sensor input consists of pins
2+ and 2–.
NOTE
T
he FX3-ANA0 can detect a sensor connection with reverse polarity (I1+ switched with
I1– or I2+ switched with I2–) as an error.
If only one individual sensor is used for a process variable, this sensor must be con‐
nec
ted in series to both inputs; see figure 57.
Sensor connection cables
The FX3-ANA0 analog input module has no shielding connections. If shielding is
required for connecting the sensors – for reasons of electromagnetic compatibility,
for example – the shield must be connected using a ground terminal that is positioned
in the control cabinet close to the Flexi Soft main module.
