14.7 Safety position if the bus fails
Abusfailureorbuserrorisindicatedbythecentralmulticolourdevicestatusdisplay(topLED).Buserrors
can occur for example due to communication problems with the IO-Link master or PLC.
Whenabusfailureoccurs,thesolenoidvalvesareswitchedtoaprogrammablesafetyposition(default:
solenoidvalvesde-energised).
Internal safety position
If internal errors are detected by the device, or if the power supply of the solenoid valves cannot be
ensured,forexampledueto(massively)exceedingorfallingshortofthepermittedpowersupply,the
“internalsafetyposition”ofthesolenoidvalvesisapproached(i.e.allsolenoidvalveso)aslongasthe
error persists.
