Achtung, tägliche Prüfung:

Vor jedem Schichtbeginn und nach jedem Werkzeug-

wechsel ist die Lichtschranke wie folgt zu prüfen:

Test 1: Bild 1 bis 3

Test 2: Bild 4 und 5

Test 3: Bild 6

Caution, check daily:

At the beginning of each shift or after every change

of tools the safety light barrier should be checked as

follows:

Test 1: Picture 1 to 3

Test 2:Picture 4 and 5

Test 3: Picture 6

Attention, contrôle quotidien:

Avant le début de chaque équipe de travail ou après

ou chaque changement d'outil, la barrière de sécurité

doit être contrôlée comme suit:

Test 1: image 1 - 3

Test 2: image 4 et 5

Test 6: image 6
