In dark operate (DO) mode, the output is ON when the target returns less light to the sensor than the configured target and OFF when the sensor detects more light than the configured/taught target. In light operate (LO) mode, the output is ON when the target returns the same or more light to the sensor and OFF when the sensor detects less light than the configured/taught target. In opposed and retroreflective sensing modes , light operate is active when the beam is unblocked and dark operate is active when the beam is blocked. In diffuse and fixed field sensing modes , light operate is active when the target is present and dark operate is active when the target is absent. ## Installing Fibers ## Cutting Unterminated Plastic Fibers Unterminated plastic fibers are designed to be cut by the user to the length required for the application. To facilitate cutting, a Banner model PFC-1 cutting device is supplied with the fiber. Cut the fiber as follows: ## PFC-1 Cutting Device Use small ports for fiber sizes: - 0.25 mm (0.01 inches) - 0.5 mm (0.02 inches) Use large ports for fiber sizes: - 0.75 mm (0.03 inches) - 1.0 mm (0.04 inches) **==> picture [108 x 67] intentionally omitted <==** **----- Start of picture text -----**

All rights reserved. www.bannerengineering.com page 14 of 21 12-Mar-26 QS18 Series Sensor Product Manual Installation Instructions 2. Determine the length of fiber required for the application. If using a bifurcated fiber, separate the two halves of the fiber at least 51 mm (2 inches) beyond the fiber-cutting location. 3. Lift the top (blade) of the cutter to open the cutting ports. 4. Insert one of the control ends through one of the cutting ports on the cutter so that the excess fiber protrudes from the back of the cutter. 5. Double-check the fiber length, and close the cutter until the fiber is cut. 6. Using a different cutting port, cut the second control end to the required length. NOTE: To ensure a clean cut each time, do not use a cutting port more than once. 7. Gently wipe the cut ends of the fiber with a clean, dry cloth to remove any contamination. Do not use solvents or abrasives on any exposed optical fiber. ## Install the Plastic Fibers Follow these steps to install the plastic fibers. **==> picture [260 x 100] intentionally omitted <==** **----- Start of picture text -----**

1. Slide the fiber gripper up to unlock it (A). 2. If using 0.25 mm or 0.5 mm core fibers, slide the plastic fiber adapters onto the fibers, flush with the fiber ends. 3. Carefully insert the prepared plastic fiber ends into the ports (B) as far as possible without applying extra force. 4. Slide the fiber gripper down to lock the fibers in place (C). ## Install the Glass Fibers Follow these steps to install the glass fibers. **==> picture [153 x 137] intentionally omitted <==** **----- Start of picture text -----**
