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. Model 709-RVC NLP will monitor the battery voltage and the fresh water and sewer holding tanks. -
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 If a sender is operating properly and connected to the display with good wiring, then the display will show the level normally. If the wiring is disconnected, shorted, or cut, or if the sender panel is defective, then the display will indicate an error code. The various error codes are shown in the troubleshooting chapter.

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 RV-C Bus Communication: RV-C is a communications protocol based on CAN that is used for control, coordination, and diagnostics. Note: Anyone that intends on connecting to the RV-C bus should have a knowledge of the RV-C specification. For more information on RV-C protocol go to: http://www.

Page 8: Chapter 4 - Display Calibration
CHAPTER 4 - DISPLAY CALIBRATION To program the 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 9 4. When the programming mode is entered, the display will show “FrS” if entering the number of senders for the fresh tank, “GrS” if entering the grey tank, or “bLS” if entering the black tank. When this occurs release both buttons. 5.
- Page 10 7. To set the alarm point, the GREY button increases the value, FRESH button decreases the value, and the BLACK button cycles through the trip polarity and the inclusion in the common alarm output. The BATT button saves and returns to the previous menu.
- Page 11 To check the primary/secondary mode: 1. Press and hold down the BATT button, the display will show the battery voltage. While continuing to hold down the BATT button, press and hold down the BLACK button. Continue to hold down both buttons for about 5 seconds until the display shows “Pri”...

Page 12: Chapter 5 - Sender Programming
CHAPTER 5 - 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 13 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.

Page 16: Chapter 6 - Installation Guide
CHAPTER 6 - 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 17 configuration to use and how long the senders should be.

- Page 20 of both ES senders will be 21”. Make both senders 10.5” long. 7. To make the senders the right length (assuming they are too long) they will need to cut off with a pair of scissors. The end CAUTION: DO NOT cut the sides, and DO NOT cut the 710ES sender shorter than 4 ”.
- Page 21 Make sure that the wires from the sender CAUTION: are routed to the RIGHT side of the sender, away from the sender. NEVER route the wires to the left of the sender. If they drape over the sender they could affect the reading. the display and the senders have the same ground.
- Page 22 16. If equipped, connect the pump switch as required. 17. Verify that the battery voltage reads correctly. If it appears low, make sure you have good wiring for the 12 volt power and the ground. 18. The common alarm output provides a connection to ground when the alarm is active.

CHAPTER 7 - TROUBLESHOOTING GUIDE If a sender or its wiring is not operating properly, the following codes are shown on the display: DISPLAY CODE POSSIBLE CAUSE SOLUTION Open circuit 1. If a sender is unresponsive. See “Wiring Diagnostics” O P n 2. - Page 25 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 26 The diagnostics can be used to check the wiring and the senders: 1. 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. If all the senders are removed but a short circuit still shows, then the wiring may be shorted.
- Page 27 3. To check the diagnostics, press and hold the button for the tank to be checked, the display will show the level for that tank. 4. While continuing to hold down the button for the tank, press the BATT button. When the display shows ”dIA”, release the buttons, the display will then change to showing the signal power diagnostic.
- Page 28 What to do in dual console systems if the two displays do not read the same: 1. For dual display console applications, if the consoles disagree the most likely reason is a bad console ground. Both console grounds, and the sender grounds, must be connected together with ground wiring.
- Page 29 “see” the water will ensure proper level calculation and sender operation. 2. The signal strength should be in the 50% range for best performance. If the signal strength is in the 20% range it is indicative of a high resistance in a connector, a bad ground, or improper bonding of the sender to the tank (a possible air gap on one or both sides of the sender).
- Page 30 for the wall thickness when positioning the sender board (usually ½” to 1” margin from the outer shell). If the sender is positioned above the vent then the maximum reading may be less than 100%. 7. There may be a buildup on the inside walls of black and grey tanks.
- Page 31 3. Another possibility is a tank wall thickness issue that may occur at the corners or edges of the tank. This has not been a common issue, and the only correction you can make is to move the board slightly lower, away from the thick area. What to do if sender delamination occurs: 1.
- Page 32 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.
