An output is activated when it switches from OFF to ON-state and it is deactivated when it switches from ON to OFF-state. 3.4.2 Output functions The function of each digital output must be programmed through the Inxpect Safety application. The available functions are the following: System diagnostic signal: switches the selected output to OFF-state when a system fault is detected.
Page 23
(e.g., System diagnostic signal, Muting enable feedback signal and Restart feedback signal) WARNING! To use Inxpect SRE 100 Series for a category 3 safety system, both the channels of a safety output must be connected to the safety system. Configuring a safety system with only one channel safety output may result in serious injuries due to an output circuit fault and a failure of the machine to stop.

For details, see "Control units" on page 15. 3.9.2 MODBUS communication enabling In the Inxpect Safety application, click on Admin > MODBUS Parameters and check that the feature is enabled (ON). Within the Ethernet network, the control unit acts like a server. The client must send requests to the IP address of the server on the MODBUS listening port (default port is 502).
Page 31
3.10 System configuration 3.10.1 System configuration The control unit parameters have their own default values that can be modified via the Inxpect Safety application (see "Configuration application parameters" on page 112). When a new configuration is saved, the system generates the configuration report.
Page 33
WARNING! Before activating one of the preset configurations through the safety Fieldbus, ensure that none of the digital inputs is configured as Dynamic configuration switch; otherwise, the Inxpect SRE 100 Series ignores all the switches made through the safety Fieldbus.

4. Functioning principles 4.1.5 Interference with pacemakers or other medical devices Radiation from Inxpect SRE 100 Series does not interfere with pacemakers or other medical devices. 4.2 Detection fields 4.2.1 Introduction The field of view of each sensor can be composed of up to two detection fields. Each of the two detection fields has a dedicated detection signal.
Page 37
According to EN ISO 13849-1, the architectures of the control unit and S101A sensor are classified respectively as category 3 equivalent and category 2. Since Inxpect SRE 100 Series is composed of the control unit and sensors together, it can be classified category 2 or category 3 equivalent based on the installation configuration and layout.
Page 38
4. Functioning principles Inxpect SRE 100 Series compliance with PL d, category 2 architecture is always guaranteed, and does not require the installer to perform any additional operation. There is no parameter combination that can lead to a configuration which has a risk reduction lower than PL d, category 2.

1. In the Inxpect Safety application in Settings > Restart function, select Automatic. 2. In the Inxpect Safety application, in Configuration for each detection field in use with automatic restart, select the desired Safety working mode and set the Restart timeout (or the T parameter, if present).
Page 49
Restart signal (Settings > Digital Input-Output). See the Fieldbus protocol for details. 4. In the Inxpect Safety application, in Configuration for each detection field in use with safe manual restart, select the Safety working mode among those allowed and set the Restart timeout parameter value.
Page 51
The muting function is enabled only if both logic signals of the dedicated input meet certain characteristics. Below is a graphic representation of the signal characteristics. In the Inxpect Safety application, in Settings > Digital Input-Output it is necessary to set the parameters that define the signal characteristics.

6.4 Multi-control unit Synchronization 6.4.1 Introduction The multi-control unit synchronization function is necessary when multiple Inxpect SRE 100 Series are sharing the same area and it allows the interferences between their sensors to be removed using a time synchronization signal.
Page 55
6.4.5 Enable the multi-control unit synchronization function 1. For each control unit, in the Inxpect Safety application click Settings > Multi-control unit synchronization and assign a different Control unit channel. Note: if there are more than four control units, the control units with the same channel must have their monitored areas as far from each other as possible.
