Parameter LC..DT: Discrepancy time within which both coils
LC..I1 and LC..I2 must have the same status. If the discrepancy
time is not activated, the status change of an LC..I input coil will
immediately cause a check whether the other reacted at the
same time. If this does not occur, no enable is initiated and an
error signal is output.
Can be used as an adjustable constant.
e Contact LC..QS: Closes when conditions for safe operation are
fulfilled and enables the hazardous movement.
Use only in the safety circuit diagram.
f
Contact LC..ER: Closes in the event of an error.
Use in the safety and in standard circuit diagram.
g
Actual value output LC..QV: Indicates the current actual value
of the discrepancy time.
Indicated on the device or in easySoft-Safety.
h Diagnostics output LC..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 LC..I1 and LC..I2 directly to the device terminals
IS1 to IS14. Example of a light curtain function block:
Figure 200: Wiring of input coils
You can associate the function block contact LC..QS directly
with one or several safety device outputs, for example:
