  • 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 2 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, servicing is greatly aided with the diagnostic information.

    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 Note: If using two displays (i.e. a primary and a secondary display), then only the primary display should have a connection to the LPG tank. If both displays are connected to an LPG tank, then an incorrect reading will result. The primary display relays LPG levels to the secondary display through the sender wiring.

  • Page 22: Chapter 5 - Display Calibration

    CHAPTER 5 - 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 23 To program the display LED brightness: 1. If the display is to be used inside the coach, the LED brightness should be low. If it is to be used in the service bay area where sunlight can reach it, the LED brightness should be high. 2.
  • Page 24 5. The display will now show “0SE” (zero senders/disabled), “1SE” (one sender) or “2SE” (two senders), based on what is currently programmed into the display. These are the only three options; the display will not work with more than two senders per tank.
  • Page 25 Trip Polarity: While the BLACK button is held down, the display shows “Hi” on the left for a high level alarm or “Lo” for a low level alarm. After the button is released, the left digit shows “H” for a high level alarm which means the alarm turns on (closes) when the fluid level is equal to or higher than the set point, and the alarm is off (open) when the fluid level is below the set point.

  • Page 27: Chapter 6 - Sender Programming

    CHAPTER 6 - SENDER PROGRAMMING To program the 710ES or 710SS 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, or black tank.
  • Page 28 2. The senders default to single or bottom operation if the programming is not altered. Consequently, if the sender is for single or bottom operation, nothing further needs to be done to it (beyond programming it for the correct tank). 3.

    CHAPTER 7 - INSTALLATION GUIDE 1. Please refer to the “Troubleshooting and Installation Tips” section in Chapter 7 for details on avoiding installation issues. 2. 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.

  • Page 36 connected back to the display ground or the breaker panel ground. 14. All that remains now is calibration and testing. The tank senders will self calibrate to whatever length they are cut, so they will always read from 0% to 100%. The display needs to be set to a single or double sender system for each tank.

    CHAPTER 8 - TROUBLESHOOTING GUIDE Display trouble codes: If a sender or its wiring is not operating properly, the following codes are shown on the display: 1. 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 39 7. The only diagnostic code available for the LPG sender is the open circuit indication “OPn”. If the wiring to the LPG sender is shorted then the LPG reading will always show “0”. 8. There are no diagnostics for the battery voltage. The diagnostics can be used to check the wiring and the senders: 1.
  • Page 40 The sender height is the number of receive segments present in the sender. To determine the length of the sender, multiply the calibration by 2.0 (SS sender) or 1.5 (ES sender) or 1.0 (JS sender) to get the length in inches. The senders always auto calibrate to the length that they are cut, so this diagnostic allows the user to confirm the length and to make sure that the auto calibration is working properly.

With the console installed you can check the level on each tank, if you get an indicated level of 10% to 20% and you know this is too high, reposition the sensor board as follows: In the case of a convex tank bottom, usually found on large flat tanks, raising the sender is the best solution to accomplish a...
  • Page 43 7. There may be a buildup on the inside walls of black and grey tanks. We get calls occasionally about older coaches that have not been in service for a few years in which the black tank will now indicate a level even though it is empty. The likely cause is that the tank has a significant build-up, probably exceeding ¼”...
  • Page 44 What to do if sender delamination occurs: 1. We have had reports of the senders literally falling off the tanks or showing serious delamination. This is likely caused by a lack of tank surface preparation. Surface prep is very simple, wipe the area to be adhered to with products like Pro Bond, alcohol, or acetone.
  • Page 45 2. When fastening the display to the panel, make sure that it is centered in the hole and not resting on one edge. 3. Non-conductive mounting spacers are available to help prevent damaging the display. Contact Garnet for further details. How to avoid damaging the display or pump switch due to excessive current: 1.
