IMPROPER CONNECTION OF LOAD
For safety reasons, the loads must be connected between terminals 4-6 and between terminals 5-6 .
Failure to comply with these instructions could result in death or serious injury.

Test contact may be used for additional external relay checking. When the link between the two contacts is open, the light curtain
is in the alarm condition and the red test indicator on the emitter is illuminated as well as the red operation indicator on the
receiver. To return to the green condition, the link between the contacts must be re-established.
The Normally Closed contact must remain open for at least 40 ms to generate a test sequence, and it takes 200 ms for the
light curtain to restart after closing the test contact.
WRONG TEST INPUT CONNECTION
The test input is NOT voltage free. Do not power the test input with any voltage supply.
Failure to comply with these instructions will result in product damage.
