Common Features; Error Contact Er; Enable Parameter, En Enable Coil - Eaton easySafety Manual

Common features

easySafety signals when a rule is broken and specifies the
number of the rule that was broken during an attempt to
switch to the RUN operating mode. Both the easySafety
device as well as the easySoft-Safety software help you to
observe these rules by means of a plausibility check.
Further details are provided in the description of the indi-
vidual function blocks.
The following features described are the same for all safety
function blocks. They are therefore summarised here and are
not mentioned in the individual descriptions.

Error contact ER

As soon as a safety function block finds impermissible states
or timeouts of monitored times at its coils, the ER error
contact closes to indicate a general error. This signal is avail-
able both in the standard as well as safety circuit diagram.
Further information on the cause of the error is provided at
the DG function block output. This can be indicated in the
status display or in the simulation function of easySoft-
Safety. Furthermore, it is possible to evaluate the individual
states of the safety function blocks and further process them
by using the DG diagnostics function block in the standard
circuit diagram a page 237.

Enable parameter, EN enable coil

(external enable, factory setting: NEN)
If the enable parameter is set to EN, the enable coil of the
function block is used so that the function block can be acti-
vated and deactivated externally. If this coil is not active, the
function block remains deactivated and its enable contact
QS stays switched off, irrespective of whether the safety
conditions are fulfilled or not.
