3. Using the 8 phillips head screws, attach the receiver and the transmitter to the two mounting plates (Fig 2A).
4. Using the wing nuts, attach the receiver and the transmitter of the photo system to the mounting L-brackets (with
arrow pointing up) as shown in Fig 2B. Note that the receiver and transmitter can be installed on the left or right
side of the door. For applications requiring the photobeams to be further away from the wall, use the extension
brackets provided as shown in Fig 2C
5. Adjust the position of the transmitter and receiver on the slot of the brackets and tightly secure the wing nuts
6. Loosen the 4 fastening screws and remove the cover from the photobeam transmitter and receiver housings and
insert electrical wire through the strain relief (Fig 3A). Pair the two white/grey wires together from transmitter and
receiver
7. Connect these paired wires to the P1 and P2 terminals on the logic board (or interface module if applicable) as
shown in Fig 3B. Use minimum 18 gauge wires and secure the wires to wall or ceiling.
For Nema-1 and Nema-4 photobeams:
Aligning the photo beams:
1. Turn the power on to the operator. If the transmitter and receiver are installed properly, the lights on both the
transmitter (red L.E.D.) and receiver (green L.E.D.) will be ON.
2. If the photo beams are not aligned properly, the receiver light (green) is OFF. Adjust the position of the transmitter
and/or the receiver on the slot of the mounting bracket until the light on the receiver is ON and then secure to the
bracket.
Photo system operation:
MICANAN photo beams must be connected for the door to close in momentary mode (unless a MICANAN monitored 2-
wire edge is connected). When the photo system is properly installed and aligned, the infrared beam will detect any
obstruction in the path of the beam. Upon detecting an obstruction, closing door will stop and reverse to full open. The
MICANAN operator control circuit continuously monitors the correct operation of the photo system. If the photo beams are
not connected or not functioning properly, the operator will go into fail-safe mode and closing door will reverse to full
open. In fail-safe mode door can only be closed by constant pressure on close.
To test the photo system:
1. Open the door to full open position.
2. Close the door.
3. When door is closing, obstruct the beam. The door should stop and reverse.
