Creating a safety circuit diagram for an emergency-
stop circuit
The easySafety device is required to monitor the activation of
an Emergency-Stop pushbutton and switch off the machine
via a load contactor using the ES.. (Emergency Stop,
page 371) safety function block.
To do this, the Emergency-Stop pushbutton is wired via the
easySafety device terminal IS07 to the function block input
ES..I1 (coil). The function block output, contact ES..QS,
controls a load contactor via the easySafety device output
QS02. This load contactor switches the machine. This load
contactor switches the machine.
The rules to be observed are provided in the description of
the safety function blocks (
circuit diagram” on page 341).
The example contains a single-channel emergency-stop
circuit.
ES.. is used here in Manual Start (MST) mode.
After the Emergency-Stop button is executed and later
mechanically released, you should be able to reset the ES..
safety function block via a Reset button. For this the Reset
button is wired via the easySafety device terminal IS08 to
function block input ES..RE.
