(Replace the Sensing Band immediately after detection.) 2. The F03-16PE Sensing Band is made from the following materials. Core: SUS316 Insulated sheath: Polyethylene 3. In order to prevent secondary fire damage, consider the effect of the atmosphere of the environment and the solution to be detected on the Sensing Band. 4. If the Sensing Band changes shape or color when a liquid is detected, replace the Sensing Band. Connecting the Sensing Band Bending the Sensing Band Interval Between Stickers To change the direction of the Sensing Band, bend the Sensing Band in one or two places where the core is not exposed. When securing the Sensing Band with Stickers, attach the Stickers at intervals of 20 to 30 cm in places where the core is not exposed. 20 to 30 cm Bent in 1 place Bent in 2 places Note: Bend the Sensing Band approximately 4 cm (i.e., twice the distance between places where the core is exposed) away from places where a Sticker is attached. If the Sensing Band is bent at places further away than this, the Sensing Band may come away from the surface. Stripping and Connecting Terminals 1. Cut into the Sensing Band approximately 4 to 6 cm in from the end as shown in the diagram below. 2. Strip away approximately the last 9 mm of the sheath to expose the core (SUS line). 3. To connect to the Terminal Block, insert the screwdriver (see note 3) from the top of the Terminal Block and insert the stripped end of the core from the side. (Refer to Dimensions on page 1.) Sensing Band Sticker Note: 1. When using the F03-26PES (adhesive-tape model), be sure to wipe all moisture, oil, and dust from the surface to which the Sticker is to be attached. Failure to do so may result in insufficient adhesion, and the Sticker may peel away from the surface. 2. When using the F03-26PEN (screw model), before installing the Sensing Band, it is necessary to perform stud welding. For details on the pitch of the studs, refer to the information on the dimensions of Sensing Band Stickers. 3. Commercially available screwdrivers can be used. It is recommended, however, that either a 210-350/01 screwdriver or a 209-132 operating tool to connect jumpers, both manufactured by Wago Japan, is used. Contact http://www.wago.com. Insert 4 to 6 cm 9 mm Exposed part of core F03-20 Terminal Block Note: Check that the wiring is secure before using the K7L in applications. 2 F03-15 Liquid Leakage Sensing Band Precautions Refer to the following installation methods and install the Sensing Band securely using the proper method for the location and environment. 1. Post or Beam Mounting Use fasteners, such as concrete anchors, to secure the Sensing Band every 500 to 1,000 mm to ensure that it does not come loose. If the surface of the post or beam is very uneven, apply two-sided tape to the mounting surface first and then secure the Sensing Band to the tape with the fastener. 2. Conduit Installation For vertical conduits, wrap the Sensing Band around the conduit at a pitch 2 to 3 times the diameter of the conduit. For horizontal conduits, secure the Sensing Band at appropriate intervals along the bottom of the conduit using an insulated adhesive strap, such as Insulock, to ensure that the Sensing Band does not come loose. 3. Dike and Catch Basin installation Use the specified stickers (sold separately) to secure the Sensing Band at appropriate intervals to keep it flat in the dike or catch basin. 4. Floor Installation Estimate the leakage detection area and use stickers to secure the Sensing Band at appropriate intervals on the floor and around equipment. Cover the Sensing Band with plastic or metal molding to protect it from contact with other objects and from being stepped on by workers. Leave a 50- to 100-mm gap in the molding at approximately 500-mm intervals where it touches the floor to allow liquids to pass through. 5. Do not install the Sensing Band in locations where condensation is likely to occur. 6. Mount the Sensing Band as close as possible to the mounting surface. Make sure that any gaps are no more than 2 mm in horizontal installations, such as the floor, and no more than 1 mm with vertical installations, such as posts and beams. 7. Attach an insulated protector, such as plastic molding, securely to the Sensing Band to protect it from contact with power cables carrying over 300 V. 8. Normally leaking materials detected by the Sensing Band will evaporate and the Sensing Band will return to its original state. The Sensing Band may not return to its original state and will have to be replaced, however, if the leaking material contained conductive impurities. Follow the appropriate replacement procedures. 9. The Sensing Band is not designed to be used as electrical wiring and must not be used for any purpose other than leak detection. 10.Do not apply petroleum-based products, such as wax, to the Sensing Band. Otherwise, liquids may be repelled and detection may fail.

Use this information when selecting a model. Can one K7L Amplifier be used for detection in more than one place? Yes. By using Terminal Blocks to connect Sensing Bands in parallel, detection can be performed in more than place with only one K7L Amplifier. Total: 400 m max. Can a different terminal block (e.g. a commercially available terminal block or a terminal block constructed by the user) be used instead of the one provided? Yes. When using another terminal block, however, be sure to check that all the terminals are mutually isolated, and that there is no danger of ground faults in connecting cables or Sensing Bands. Terminal TerminalBlocks Block K7L-U Can the K7L Amplifier detect pure water? Yes. Note: 1. When wiring, be sure not to exceed the maximum possible wiring distances for both the connecting cable and the Sensing Band. Exceeding these distances may lead to faulty operation. Connect one Sensing Band to each Terminal Block. 2. Not applicable to the K7L-UD. Even pure water, which has a resistance exceeding 10 MΩ⋅cm, can nearly always be detected if the K7L is used at its maximum sensitivity. This is because impurities are mixed with the water when it is leaked and the resistance drops. Pure water Impurities in the air Can the K7L Amplifier be used as a replacement for the 61F-GPN-V50 Water Leakage Detector? Can the K7L Amplifier detect oil? Yes. Because the surge withstand capability is different, however, do not use in locations where it will be exposed to impulses and surges, such as outdoor roofs or in pump panels. Also, items such as the power supply voltage and the connection sockets are different. Check these items before application. No. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
