d
Parameter EN..ED: The enable time is the maximum time in
which the guard is allowed to be bridged. When the time has
elapsed, the enable is removed and EN..QS is opened.
If the enable time is not activated, the enable contact EN..QS is
closed for as long as the EN..I1 and EN..I2 function block coils
are picked up.
Can be used with the enable switch as an adjustable constant.
e
Contact EN..QS: Closes when the enable switch is actuated
correctly and initiates the enable signal for special operation.
Use only in the safety circuit diagram.
f
Contact EM..ER: Closes in the event of an error.
Can be used in the safety and standard circuit diagram.
g
Actual value output EN..QV: Indicates the current actual value
of the enable time.
Indicated on the device or in easySoft-Safety.
h
Diagnostics output EN..DG: Provides information about the
states of the function block.
Evaluation only in the standard circuit diagram with the diag-
nostics function block DG.
Wiring of the function block
Wire its coils EN..I1 and EN..I2 directly to the device termi-
nals IS1 to IS14. Example of the assignment of the enable
switch to the safety function block inputs:

Wiring of input coils
You can associate the function block contact EN..QS directly
with one or several safety device outputs, for example:
