TruGuard Reflective
MODEL: TG-R-K10

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 TruGuard Reflective monitored and fail-safe photo optic system is a UL Recognized Component that meets the UL 325 requirement. The TruGuard Reflective consists of an emitter/receiver unit and a reflector with a hood. The emitter/receiver is 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 or stop and reverse motion.

INSTALLATION

Select a stable mounting location with a clear line of sight, across the protected area, to detect obstructions. The light beam should not be obstructed by plants, leaves, etc.

Mount the emitter/receiver vertically or horizontally in its desired location. (Image 3)
a) Using the appropriate hardware required by the mounting surface, attach the mounting bracket.
b) Install the emitter/receiver into the bracket. (Image 1)
i. Place provided nuts into the top and bottom recessed corners of the emitter/receiver. (A)
ii. Slide the emitter/receiver into the bracket. (B) The lens should point across the protected area toward the reflector mounting location.
iii. Place washers onto screws and insert through bracket and emitter/receiver from the side opposite the nuts. Finger tighten to secure in place. (C)
Power the emitter/receiver. To avoid the risk of electrocution, turn off and disconnect power to the operator before wiring.
a) Connect the emitter/receiver to the operator per the wiring diagram. (Figure 1)
b) Apply power to the operator.
c) Confirm the green LED light on the emitter/receiver has turned on. (Figure

Mount the reflector in its desired location. (Image 2)
a) Install the reflector hood using the appropriate hardware on the opposite side of the protected area from the emitter/receiver.
b) Secure the reflector to the hood with the provided center screw, noting the marking on the back of the reflector for up orientation.
Align the emitter/receiver with the reflector.
a) Aim the powered emitter/receiver toward the reflector. You can stand or kneel beside the unit, sighting along it and viewing the reflector, to help with alignment. (Image 4b) With the hardware loosened, turn the emitter/receiver left and right and/or up and down until the yellow light turns solid. (Image 3)
c) Tighten the mounting screws. Do not overtighten the through-unit screws.
