Checking the circuit diagram
EZ contains a built-in measuring device enabling you to
monitor the switching states of contacts and relay coils during
operation.
XComplete the small parallel connection and switch EZ to
RUN mode via the main menu.
XReturn to the circuit diagram display.
You are now unable to edit the circuit diagram.
The circuit diagram display performs two functions depending
on the mode:
STOP: Creation of the circuit diagram
RUN: Power flow display
XSwitch on I3.
In the power flow display, energized connections are thicker
than non-energized connections.
You can follow energized connections across all rungs by
scrolling the display up and down.
I2---u---ÄQ4
I3---k

If you switch to the circuit diagram display and are unable to
modify a circuit diagram, first check whether EZ is in STOP
mode.

The power flow display will not show signal fluctuations in
the millisecond range. This is due to the inherent delay
factor of LCD displays.
