The button func-tion is a useful addition for service and commissioning tasks.Figure 86: The cursor buttons are wired in the circuit diagram as contacts P 01 to P 04.Requirement:The P buttons must have been enabled in the system menu.Example 1This standard circuit diagram example enables a lamp at output Q1 to either beswitched on or off via the inputs I1 and I2 or via the cursor buttons ÍÚ.Figure 87: Switch Q1 via I1, I2, Í, or ÚExample 2This circuit diagram example causes output Q1 to be actuated by input I1. I5 switchesto cursor operation and disconnects the rung I 01 via M 01.Figure 88: I5 switches to cursor buttons.The easyE4 device only evaluates P button entries if the statusdisplay is shown.142 easyE4 11/18 MN050009 EN www.eaton.com
