WIRING CONNECTIONS
Do not run wiring in the same conduit with AC power.
1. Disconnect power to the operator.
2. Wire the coil cord to the junction box. Twist both black/white wires from the photoelectric sensors together and connect them to the white wire
from the coil cord. Twist both black wires from the photoelectric sensors together and connect them to the brown wire from the coil cord. NOTE:
The black/white wire is common, and the black wire is positive.
3. Connect the coil cord wires to the logic board on the operator. The wiring is polarity sensitive so make certain to wire as indicated:
Medium Duty Logic:
Connect the white wire to the LMEP2 and the brown wire to LMEP1 on the logic board.
FDO, FDC, FDCL and Egress Operators:
Connect the white wire to J2 terminal 2 and the brown wire to J2 terminal 1 on the logic board.
Heavy, Standard Logic 4:
Connect the white wire to the common and the brown wire to LMEP on the logic board.
Heavy, Standard Logic 4 (connected through the control station):
See illustration.
