In Configuration 4, only safety Input 1 is in use. It can either be configured for
GuardLink or OSSD with autodetect of EMSS devices. Input devices are not
shown in the drawing.
The input IN X (terminal X1) is configured for SWS In. This input is ANDed
with IN 1.
The output OUT X (terminal X2) is configured for SWS Out and can drive
any other SWS compatible device. In this example, the SWS out is driving an
EM safety relay. OUT X is switched off immediately when demanded by the
safety functions. The relay outputs 14/24 can be configured for a time delay to
switch off after the delay time.
The relay configuration is considered a middle SWS as it requires an SWS
input and provides an SWS output.
The Reset mode is configured for manual monitored reset and is assigned to
the safety outputs. The outputs are enabled when all inputs of the safety
function are ACTIVE, the feedback signal is present, and a valid reset
operation has been performed.
