INSTALLATION INSTRUCTIONS
TruGuard™
Reflective Photo Optic System
MODEL: TG-R-K10
TG-R-K10 Photoeye UL Elite Gates
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 monitored and fail-safe reflective photo optic system is a UL Recognized Component that meets the UL 325 requirement. The TruGuard consists of an emitter/receiver unit with a mounting bracket/hood and a reflector with 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 and/or reverse motion.
CONTENTS
- (1) Emitter/receiver (unit)
- (1) Emitter/receiver bracket/hood
- (2) Emitter/receiver through-unit screws
- (2) Emitter/receiver through-unit nuts
- (2) Emitter/receiver through-unit washers
- (1) Polarized reflector
- (1) Reflector hood
- (1) Reflector center screw
REQUIRED
- Mounting hardware as required by mounting surface
- Hand tools for hardware installation
RECOMMENDED
- Operator manual
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/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 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 2) - Mount the reflector in its desired location. (Image 2)
a) Install 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.
4. 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 4)
b) With the hardware loosened, turn the emitter/receiver left and right and/or up and down until the yellow light turns on solid. (Image 3)
c) Tighten the mounting screws. Do not overtighten the through-unit screws.
