The following is a step-by-step example of how to wire your
first standard circuit diagram and first safety circuit diagram.
In this way you will learn all the rules, quickly enabling you
to use a easySafety device for your own projects.
Normally you wire the safety circuit diagram following the
procedure described here. However, certain rules must be
observed here and these are explained fully in section "Rules
in the safety circuit diagram" on page 341. The following
shows the most important rules for creating your first
standard circuit diagram and the first safety circuit diagram.
Warning!
Important rules for the first safety circuit diagram
• Wire coils ...Ix of the safety function blocks directly to
the contacts of the device inputs ISx. Branches and
wiring to other contacts are not allowed!
• Inputs IS.. for which the debounce function is set must
not be used in the safety circuit diagram.
• Inputs IS.. may be used in the safety circuit diagram and
in the standard circuit diagram at the same time.
• A safety device output such as QS2 can either be used
only in the safety circuit diagram or in the standard
circuit diagram as a coil, i.e. a safety output that was
used in the safety circuit diagram is then no longer
available for use in the standard circuit diagram and
vice versa.
• A safety device output must only be used once as a coil
in the safety circuit diagram.
Danger!
Device outputs QR and QS that are set by the standard
circuit diagram are not safety outputs and must only be
used for standard tasks. Make sure that these outputs do
not trigger any safety-related actions on the machine or
plant.
