67 SICK LSI Technical Description - 06/98
Restart after intrusion into protective field
You can program the following options in the PLS/LSI user
software (see section 9.3):
– Without delay
– Delayed by n seconds
– With restart button
Restart ”without delay”
The LSI enables the output after the pre-set response time
(scan rate) as soon as the protective field is free. The red LED
on the configured output (OSSD A or B) goes out and the green
LED lights up.
Restart ”delayed by n seconds”:
The LSI starts when the time ”n” set here has elapsed after the
protective field has become free again. After that time the red
LED on the configured output goes out and the green LED lights
up. The output is then free.
Restart ”with restart button”:
On the configured output the yellow ”Restart” LED flashes.
You must then press the restart button. Only then is the output
enabled.
Note:
When fitting the restart button, note that the button must be
mounted such that, when the button is pressed, the hazardous
area is fully visible.
The system is thus ready for operation.
