  • Page 3: Chapter 1 - Overview

    CHAPTER 1 - OVERVIEW he S Tank Monitor represents a massive leap L II forward in level measurement technology for the Recreational Vehicle industry. The SeeLeveL has a combination of features, accuracy, reliability, and diagnostic capability that have never been available before.

  • Page 4: Chapter 2 - System Description

    CHAPTER 2 - SYSTEM DESCRIPTION he SeeLeveL consists of a display unit that mounts inside the RV, and sender panels that stick to the side of the holding tank. A single two conductor wire is used to connect all the sender panels to the display.
  • Page 5 defective, then the display will indicate an error code. The various error codes are shown in the troubleshooting chapter. With these diagnostic features and the digital nature of the tank level sensing technology, it is almost impossible for the system to indicate an incorrect water level, and in the very unlikely event it does occur, the user can verify what is happening with the diagnostic information.

  • Page 6: Chapter 3 - Operating Instructions

    CHAPTER 3 - OPERATING INSTRUCTIONS he display is the only system component that is accessed by the user. All user input to the display is done using the five buttons along the bottom of the display. Operation of the display is as follows: To read a water or sewer tank level: 1.
  • Page 7 4. There is no hold mode for the LPG. The LPG tank level cannot change fast enough to justify the use of the hold function, except during filling of the tank. The gauge should not be used as a full tank shutoff indicator since the LPG sender in the tank is not reliable or accurate enough to be used as a safe indicator of a full tank.

  • Page 8: Chapter 4 - Display Calibration

    CHAPTER 4 - DISPLAY CALIBRATION To calibrate the LPG sender: 1. The LPG tank must be full when the sender is calibrated, otherwise the calibration will be invalid. Fill the LPG tank by using an alternate measurement method, such as weight, a spit valve, or a mechanical gauge on the tank.
  • Page 9 To program the number of senders for each tank: 1. The fresh and black tanks can have one or two senders, so this information must be programmed into the display. The grey and galley tanks can only have one sender each, so no programming is possible for the number of senders.

  • Page 10: Chapter 5 - Sender Programming

    CHAPTER 5 - SENDER PROGRAMMING To program the sender for the correct tank: 1. Since the senders are all connected in parallel to save wiring and to simplify installation, the senders must be programmed so they know which tank they are on. The senders can be programmed for either the fresh, grey, galley, or black tank.
  • Page 11 2. Since the senders are all connected in parallel to save wiring and to simplify installation, the senders must be programmed so they know whether they are a single, top, or bottom sender. This is done with the tab at the top center of the sender. See the following diagram.

    CHAPTER 6 - INSTALLATION GUIDE (NEW OEM INSTALLATIONS ONLY) 1. The installation consists of mounting the display inside the RV, cutting and fastening the senders to the sides of the holding tanks, connecting wiring, and programming the display. 2. Mount the display by cutting a hole in the wall 3” wide by 1 7/8”...
  • Page 14 7. For tanks greater than 13” tall, two stacked senders are used. The sender ends should be 1/4” to 3/4” away from the top and bottom of the tank, to allow for the thickness of the tank top and bottom and any bows in them (see the diagrams). The senders are calibrated to account for this distance from the bottom of the tank.

  • Page 16 12. Connect all the blue wires from the senders together, and to the blue wire from the display. Connect the black wire from each sender to ground. Use Marrette or crimp connectors to fasten the wires together. Make sure that the wires from the sender are routed away from the sender, if they drape over the sender they could affect the reading.

If a sender is unresponsive or there is an open circuit in the wiring so that the sender is not connected, the display will indicate an open circuit by showing “OPn”...
  • Page 19 7. The diagnostics can be used to check the wiring and the senders: If a short circuit is showing, disconnect the senders one at a time at the sender location. If the short circuit indication goes away when a sender is removed, then that sender is bad.
