Function
The evaluation system SB4 is an ESPE of type 4 (EN 61496-1 or IEC 61496-1) or category 4 (EN 954-1). This system is also
designed and tested according to IEC 61508. It meets the requirements for the SIL3.
The operating instructions supplied with the device must be observed for planning, installation and operation.
A maximum of 4 safety light barriers can be connected to the evaluation device. Instead of the light barriers, other contact safety
equipment can be connected.
Operating modes
By default, the restart interlock is activated.
Each assembly contains DIP switches for selecting the functions. For selecting functions, 2 selector switches must always be
actuated.
Switches on the first assembly:

Position
1 and 3
OFF
Without restart interlock (restart, RI)

Displays
The OSSD-R/supply module on position 1 has a red/green LED for indicating the OSSD on/off statuses, a yellow LED for the
start-ready status and a 7 segment display for system diagnosis.
The 7 segment display indicates the status and the error codes of the system.
