Page 3: Chapter 1 Overview
CHAPTER 1 OVERVIEW The SeeLeveL I Tank Monitor represents a massive leap forward in level measurement technology for the Recreational Vehicle industry. SeeLeveL has a combination of features, accuracy, reliability, and diagnostic capability that have never been available before. The SeeLeveL I will monitor the battery voltage, the water and sewer holding tanks, and the LP Gas tank. -
Page 4: Chapter 2 System Description
CHAPTER 2 SYSTEM DESCRIPTION The 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. The Sender: Each sender panel is a flexible self adhesive printed circuit board which is stuck to the side of the holding tank. - Page 5 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 The 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: Press the button corresponding to the tank to be checked and release it, the display will show the level in percent on the LED bar graph. - Page 7 If another button (including BATT or LPG) is pressed before the 5 second time is up for the first button, the display will immediately switch to showing the new level or voltage. The 5 second timeout is restarted every time a button is pressed. To continuously display a reading, press and release the desired button, and then press the same button a second time.
- Page 8 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 9: Chapter 4 Display Programming
CHAPTER 4 DISPLAY PROGRAMMING To program the LED brightness: 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. To program the LED brightness, the display needs to enter the brightness programming mode. - Page 10 display matches with the number of senders connected, otherwise the display will show an error. To enter the sender programming mode, press and hold down the button for the tank to be programmed, the display will show a level or an error message.
- Page 11 When the display shows the correct number of senders, press the BATT button to exit the programming mode. Each tank will need to be calibrated individually using this procedure. To calibrate the LPG sender: The LPG tank must be full when the sender is calibrated, otherwise the calibration will be invalid.

Page 12: Chapter 5 Sender Programming
CHAPTER 5 SENDER PROGRAMMING Long Stackable Senders These senders are 12 inches long and can be either single or double stacked. They are identified by the “TOP” on the middle tab. To program the sender for the correct tank: 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. - Page 13 To program the sender as top or bottom: Note that for 4 tank models, the gray and galley tanks can only have single senders, so this section does not apply to them. 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.

- Page 15 Short Single Senders These senders are 6 inches long and cannot be stacked, they must be single. They are identified by the “ALT” on the middle tab. To program the sender for the correct tank: 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.

Page 17: Chapter 6 Installation Guide (New Oem Installations Only)
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” high and bringing the wiring out through the hole to connect to the display panel connector. - Page 18 7. For tanks less than 13” tall, a single long sender is 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).
- Page 19 the sender over the side of the tank and carefully stick it down. MAKE SURE THAT THE END WITH WIRES IS POINTING UP!! Position the bottom of the sender at least 1/4” above the bottom of the tank, and more if required to equalize the space at the top and bottom of the tank.
- Page 20 13. Connect the 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.

Page 22: Chapter 7 Troubleshooting Guide
CHAPTER 7 TROUBLESHOOTING GUIDE Display trouble codes: If a sender or its wiring is not operating properly, the following codes are shown on the display: 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 the open circuit code. - Page 23 If the display has been programmed for a single sender, and dual stacked senders have been connected, the display will show the stack error code. In this case, change the senders or reprogram the display as required. If only a top sender has been connected, the display will show the no bottom error code, indicating that no bottom sender has been received.
- Page 24 For the LPG tank, the open circuit code indicates an open circuit in the wiring or a bad resistance sender in the LPG tank. If there is a short in the wiring, the display will read zero all the time. The display contains a permanent memory which is used to store the programming for battery voltage calibration value, the number of senders per tank, the LED brightness, the LPG calibration value, and the tank...
- Page 25 To review the sender diagnostics: The sender diagnostics can be reviewed periodically to check for any degradation of the tank senders. If a sender appears to be malfunctioning, reviewing the diagnostics should be the first step in the troubleshooting process. Note that there are no diagnostics for the battery voltage or LPG.
- Page 26 100% 100% 100% Too low to Low but Good operate adequate The signal power will show for 5 seconds, then the display will shut down. The display will not respond to any buttons during this 5 second period.
