32 SICK LSI Technical Description - 06/98
”Links” tab:
This is where you define which monitoring area (comprising a
protective field and a warning field) is to be monitored on which
sensor.
”I/O Definitions” tab:
This is where you define the input information on which the
monitoring case is to be activated:
X = low or high
0 = low
1 = high
You also set which input is to be switched in the event of
intrusion into the protective field.
Note:
Each input comprises two signals, which must always be inverse
to each other, e.g. for input A signals A
1
and A
2
:
– Input A low: A
1
= 1 and A
2
= 0
– Input A high: A
1
= 0 and A
2
= 1
In this, the value set in the dialog box always corresponds to the
signal level of the assigned input A
2
, or B
2
, C
2
, D
2
. (For cabling of
inputs see section 8.2).
”Evaluation” tab:
This is where you set how often (that is, in how many
consecutive scans) the sensor must detect a foreign body in the
protective field before the configured outputs are shut off
(between 2 and 16 scans are possible).
This sets the response time of the LSI.
Note:
If you combine the LSI with PLS type 101-316 for vehicle
protection, the response time of the LSI is not programmable,
but is fixed at 270 ms.
