OG-T-K10 Opti Guard Monitored Thru-Beam Photo Optic System
WARNING
Read and understand all instructions before beginning installation. Disconnect power to motor and test upon completion.
Photo optics should be installed by qualified personnel to ensure the requirements herein have been met. Keep these instructions with the installation. Always abide by local and national electrical code specifications when wiring accessories to motor controls.
The Miller Edge Opti Guard monitored and fail-safe thru beam photo optic system is a UL Recognized Component that meets the UL 325 requirement. The Opti Guard consists of an emitter and a receiver with two mounting brackets. The emitter and receiver are intended to be positioned in such a way that an obstruction in a hazardous area will interrupt the beam of light. An interruption of the beam will signal the operator to stop and/or reverse motion.

INSTALLATION
Select a stable mounting location with a clear line of site, across the protected area, to detect obstructions. The light beam should not be obstructed by plants, leaves, etc.
- Mount the emitter and receiver vertically or horizontally in their desired locations.
a) Install the emitter and receiver into their brackets. (Image 1)
i. Place provided nuts into the top and bottom recessed corners of the photo eyes. (A)
ii. Slide the photo eyes into their brackets. (B)
iii. Place washers onto screws and insert through bracket and emitter and receiver from the side opposite the nuts. Finger tighten to secure in place. (C)
b) Using the appropriate hardware required by the mounting surface, attach the mounting bracket. The emitter lens will point across the protected area toward the receiver mounting location. (Image 2) - Power the emitter and receiver. To avoid risk of electrocution, turn off and disconnect power to the operator before wiring.
a) Connect the emitter and receiver to the operator per the wiring diagram. (Figure 1)
b) Apply power to the operator.
c) Confirm the green LED lights on the emitter and receiver has turned on. (Figure 2) - Align the receiver with the emitter. (Image 2)
a) Aim the emitter toward the receiver. You can stand or kneel beside the unit, sighting along it and viewing the yellow receiver LED, to help with alignment. (Image 4)
b) With the hardware loosened, turn the emitter and receiver left and right and/or up and down until the yellow receiver LED turns on solid. (Image 3)
c) Tighten the mounting screws. Do not overtighten the through-unit screws.
