3.2.4 System status LEDs
The LEDs are each dedicated to a sensor, and can display the following statuses:
Status
Meaning
Steady green
Normal sensor function and no motion detected
Orange
Normal sensor function and some motion detected
Flashing red
Sensor in error. See "Control unit LED" on page 73
Steady red
System error. See "Control unit LED" on page 73
Flashing green
Sensor in boot status. See "Control unit LED" on page 73
3.2.5 Fieldbus status LEDs
The LEDs reflect the status of the PROFINET/PROFIsafe Fieldbus and their meaning is reported below.
Note
: F1 is the LED at the top, F6 is the LED at the bottom.

3.2.6 Inputs
The system has two type 3 digital inputs (according to IEC/EN 61131-2). Each digital input is dual channel, and
the ground reference is common for all the inputs (for details, see "Technical references" on page 86).
When using digital inputs, it is mandatory that the additional SNS input "V+ (SNS)" is connected to 24 V dc and
that the GND input "V- (SNS)" is connected to the ground in order to:
