If the feedback circuit is not needed, a jumper connection is to be fitted between the inputs X1 and X2. Circuit • Start Pushbutton s Options A start pushbutton (NO) can option- ally be connected to the inputs X1 and X2. With the guard device(s) closed, the enabling circuits are then not closed until the start push- button has been operated. If neither start button nor feedback circuit are connected, a jumper must be wired between X1 and X2. 61 Guard Door and E-Stop Safety Controllers AZR 31 T2 to Monitor One Device Typical Application Typical L1 L+ Wiring L1 Diagram 0 0 A1 S13 S24 X1 41 13 23 33 K1 S L1 L3 L2 AZR31T2 K2 A2 S14 S23 X2 42 14 24 34 L- N N M 3 SK4 CC4 0 Notes • The safety controller fulfills • AZR safety controller being used Category 0 to EN 60 204-1. to monitor an emergency-stop. • Secures to Control Category 4 to • The diagram is shown for the EN 954-1. de-energized condition.
