General Safety Instruction User manual of water sensor RSA 1.1 Safety Instruction Please read this manual and remark, sticker on product before installation or operation. Please abide by required electrical safety procedure and requirement to prevent any damage or injury. Safety instruction in this manual is not equal to these safety procedure and requirement. Manufacturer takes no responsibility for any consequence of break above safety procedure or requirement. 1.2 General Precaution To avoid fire and electric shockmake sure all cables selected with right gauge and being connected well. Smaller diameter and broken cable are not allowed to use. 2. Product Introduction 2.1 General Introduction The RSA is a resistive water level sensor developed by TBB. As one of the core functional components of TBB's system solutions, the RSA has been widely used in RVs, boats, special vehicles, and other fields. It consists of five stainless steel probes of different lengths, a plastic housing, and a wiring harness. The sensor has four levels: 25%, 50%, 75%, and 100%, enabling real-time detection of water tank levels. 2.2 Working Principle The RSA is a resistive water level sensor. The longest stainless steel probe serves as the common electrode. By detecting whether the other stainless steel probes come into contact with the water level, changes in voltage are generated to determine the remaining water level in the tank. 1 2.3 Product Appearance User manual of water sensor RSA Fig.2-1 Picture of RSA 2.4 Stainless Steel Probe Length The exposed length of stainless steel probes varies by product model.

Installation User manual of water sensor RSA 1. Drill a hole at the cover of service open. The recommended cutout diameter is 37~38mm. The product dimensions are as follows. Fig.3-1 RSA product dimensions 2. Pass RSA through that hole on service open from bottom to up. Fig.3-2 Pass RSA through the hole on service open 3 User manual of water sensor RSA 3. Pass screw cap of RSA through cable and fix it with thread body. Fig.3-3 Pass screw cap of RSA through the cable 4. Well fix the screw cap with thread body by proper tool to prevent any leakage or loose. Fig.3-4 Fix screw cap with thread body 4 User manual of water sensor RSA 5. Fix cover of service open back. The installation of RSA is finished. Fig.3-5 Fix back cover of service open Remarks 1) Please keep installation of RSA away from water inlet with distance at least 10cm. Or it will cause measurement is not accurate. 2) The probe length has been calibrated by manufacturer before delivery to customer. It's not allowed to cut probe length by user. 5 User manual of water sensor RSA User manual of water sensor RSA User manual of water sensor RSA 3)Microsoft Word LTSC
