TEST FUNCTION
The SLC / SLG 210 RF light curtain / light grid system features an automatic self-diagnosis
function that enables it to detect response time malfunctions (in an execution time less than
800ms
). This safety system is permanently active and does not require any interventions
from the outside.
The TEST function is available should the user wish to check equipment connected
downstream of the light curtain / light grid (without physically entering the protected area).
By means of this function the OSSDs can be switched from ON to OFF as long as the
function remains active. Please see Table 2 (page 11) for details about the use of the test
function.
By means of the test function, which simulates occupation of the protected area, it is
possible to verify the operation of the entire system by means of an external supervisor (e.g.
SPS, control module, etc.).
The minimum duration of the TEST function must be 40 msec.
