  • Page 9: 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, or black tank.
  • Page 10 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 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 2 1/4” wide by 4 3/4”...
  • Page 13 senders are calibrated to account for this distance from the bottom of the tank. The sender is cut to the nearest even 1.5 inch in length, for example, a system with a tank height of 11.75 inches, cut the sender to be 10.5 inches long, this allows 5/8”...

If the signal power is too low, make sure that the sender(s) is well stuck to the side of the tank and that the tank is reasonably clean inside, as a large buildup will reduce signal strength.

It will be necessary to replace the display if this occurs. The diagnostics can be used to check the wiring and the senders: 1.
  • Page 20 b. The sender height is the number of receive segments present in the sender. To determine the length of the sender, multiply the calibration by 1.5 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.
