WAGO-I/O-SYSTEM 750 Connect Devices 81750-666/000-003 4FDI/2FDO 24V/10A PROFIsafe V2 iParManualVersion 1.2.0, valid from HW/SW Version 01/01Connect connection O2B to connection O+. In addition, connect connection O1Bto connection O2A. In addition, connect connection O- to the 0V potential of thefield supply voltage.You can achieve a risk reduction of SIL3/Cat.4/PL e, for example, by readingback the switching states of the power jumper contacts from positively drivencontacts of a relay.Line break detection on the digital outputMonitoring of line breaks only works between connections O1B and O2A onlyworks in conjunction with loads switched directly using the PROFIsafe I/Omodule. If you switch interference-free I/O modules of the WAGO-I/O-SYSTEM750, then set the value of the Line break detection parameter to "inactive".Line break detection is not safety related and cannot be part of the safety functionunder any circumstances.Test pulses switch off outputs of the interference-free I/O modulesThe PROFIsafe I/O module 750-666/000-003 performs a test pulse on the digitalpower outputs every minute. These cause the outputs of the interference-free I/Omodules of the WAGO-I/O-SYSTEM-750 to shut down. If you needuninterrupted operation of the outputs, then you can switch off the cyclical testpulse by setting the Test pulse duration parameter to the value "0 ms (off)".Always observe the "No test pulses at test pulse duration = 0 ms!" safetyinformation.
