Sec-3.9
Photocells:
Actuating the operator by using constant contact on the CLOSE button will override non-functioning
external reversing devices, including photocells.
WARNING
AVERTISSEMENT
L’activation de l’operateur en util isant un contact constant sur le bouton FERMER annulera les dispositifs
d’inversions externes, y compris les cellules photoelectriques.
Photocell systems provide entrapment protection when mounted near the doorway in such a way that
the lower portion of an individual’s leg will break the photocell beam during normal walking conditions.
WARNING
AVERTISSEMENT
Les systèmes de cellules photoélectriques fournissent une protection contre le coincement pour le
montage à proximité de la porte de manière à ce que la partie inférieure de la jambe d’un individu ne
puisse pas rompre le faisceau de la cellule photoélectrique lors de passages normaux par la porte.
Section 3: Wiring
MONITORED PHOTOCELLS:
Monitored (STB) photocells FIG. 5. Wiring to these photocells can be connected to either terminal (they are
not polarity sensitive).
See ENTRAPMENT PROTECTION Sec-1.5 for approved reversing devices.
NOTE: Installer must enable ODC STB in CALIBRATION MODE. (See programming section)
NON-MONITORED PHOTOCELLS:
Nominal 24 Volt DC commercial photocells with normally open contacts can be connected as shown. FIG. 6.
NOTE: External radio connector harness supplies 20-40VDC across blue(+) and yellow(-) wires.
NOTE: If no voltage is present across blue & yellow wires, check the fuse near the external radio harness on the
board.
MOUNTING PHOTOCELLS:
1. Determine location for mounting. They do not need to be directly adjacent to the door but must be
somewhere along the wall where there will be an unobstructed line between them. FIG. 7.
2. Photocells must extend out away from the wall suciently that no door hardware breaks the plane of
the photo-beam.
