Vehicle industry. The SeeLeveL has a combination of features, accuracy, reliability, and diagnostic capability that have never been available before. Garnet’s 709-N2K series models will monitor the battery voltage, and the fresh water and sewer holding tanks. The information is displayed on a 3-digit alpha-numeric LED display. The 709-N2KP includes a pump switch. -

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 four 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 The 709-N2K reports as NMEA device class 75 (sensor communication interface) with an NMEA function code of 150 (fluid level). Garnet Instrument’s manufacturer code is 873, and the 709-N2K product code is 15197. The 709-N2K adheres to NMEA database version 2.200.

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.

CHAPTER 6 - INSTALLATION GUIDE 1. Please refer to the “Troubleshooting and Installation Tips” section in Chapter 7 for details on avoiding installation issues. 2.

- Page 20 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 to be cut is the bottom end, which is the opposite end from the top where the wires come out (see the diagrams).
- Page 21 Make sure that the wires from the sender are CAUTION: 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. 13.
- Page 22 18. The common alarm output provides a connection to ground when the alarm is active. The maximum current that can be put through the alarm output is 100mA, be sure to use a relay if more current is required. Program and test the alarm output to ensure that it functions as desired.

Page 24: Chapter 7 - Troubleshooting Guide
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 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 26 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 27 2. Always ground the senders and the console to the same ground circuit. This is very important; RV’s can have several ground circuits with resistance between them. We have had instances where two consoles are installed with a different ground for the service bay console and interior console.
- Page 28 able to measure on the optimal side. On the drain valve side, the best choice is to elevate the sender to avoid reading a puddle at the drain valve. 4. The close proximity of metal to the sender can be misinterpreted as water, since they have similar electrical characteristics.
- Page 29 the soaking hopefully the build-up will be flushed away when the tank is drained and flushed. If you still have symptoms the treatment may required a few more times. The waste did not build up on the tank wall in one day, so it may not dissolve in one treatment! The build-up looks like water to the system since it holds a significant volume of water in the build-up area.
- Page 30 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. Page 30 709-N2K NLP/709-N2KP NLP Manual...
- Page 31 How to avoid damaging the display or pump switch due to excessive current: 1. Please be aware that the water pump switch circuit has a limitation on current draw of 7.5 amps, some large pumps can draw over 10 amps. These high drain pumps must use a relay or the display console printed circuit will overheat and damage the display permanently.
