To Next PageTo Next PageWhy is there a signal power problem with my Garnet Tank Equipment?
A signal power problem with Garnet Tank Equipment may be due to several factors, including a sender detached from the tank, excessive buildup inside the tank, faulty wiring to the sender, low battery voltage, or a defective sender. Typical signal power should be between 50% and 60%, with a minimum of 20% required for proper operation. P00 represents 100%.
What to do if my Garnet SeeLeveL II 709 displays an Error?
If you see an 'Error' message on your Garnet Tank Equipment display, it indicates signal corruption between the sender and the display. This can be caused by bad wiring, faulty senders, or multiple senders programmed with the same settings. To resolve this, check that all senders are programmed correctly. If the programming is correct, try replacing the sender that is causing the error.
What to do if Garnet Tank Equipment readings jump or are inaccurate?
If your Garnet Tank Equipment readings are jumping or inaccurate, it could be due to 120VAC interference causing stalls and gaps in the readings, or resistance between multiple ground circuits in your RV. Always ground the senders and the console to the same ground circuit to resolve this issue.
What to do if dual Garnet SeeLeveL II 709 displays don't read the same?
If you have a dual console system and the two Garnet Tank Equipment displays show different readings, the most likely cause is a bad console ground. Ensure that both console grounds and the sender grounds are connected together using ground wiring.
How to avoid damaging Garnet SeeLeveL II 709 Tank Equipment display due to excessive current?
To prevent damage to the display or pump switch of your Garnet Tank Equipment due to excessive current, especially with large pumps that can draw over 10 amps, you must use a relay. This will prevent the display console's printed circuit from overheating and causing permanent damage.
What to do if my Garnet SeeLeveL II 709 freezes?
If your Garnet Tank Equipment system freezes or becomes unresponsive, try rebooting it. Shut off the 12V power to the system for a few seconds, then turn it back on.
What to do if Garnet SeeLeveL II 709 Tank Equipment shows water level after draining?
If your Garnet Tank Equipment indicates a residual or non-zero water level even after the tank is completely drained, it may be due to a convex or sloped tank bottom, or the close proximity of metal to the sender being misinterpreted as water. Temporarily install the sender using duct tape or masking tape to check the tank level before final positioning.
What to do if Garnet SeeLeveL II 709 Tank Equipment operation is erratic?
If the operation of your Garnet Tank Equipment becomes erratic or stops completely, ensure that all wiring connections are solid. Avoid using spade connectors, as they degrade over time. Use insulated crimp-on butt connectors or solder and insulate the wire connections.
What does 'Stacked senders' mean on Garnet Tank Equipment?
The 'Stacked senders' message on your Garnet Tank Equipment indicates that the display is programmed for a single sender, but double-stacked senders are connected. The display has not been configured to recognize two senders. To fix this, either change the senders or reprogram the display as needed.
What does 'No top sender' or 'No bottom sender' mean on Garnet SeeLeveL II 709?
If your Garnet Tank Equipment display shows 'ntP' or 'nbo', it means the display is programmed for double-stacked senders, but only one sender is reporting. 'ntP' indicates only the bottom sender is reporting, while 'nbo' indicates only the top sender is reporting. Correct the programming on the sender to resolve this.

The SeeLevel II™ is a series of holding tank monitors designed for Recreational Vehicles, providing accurate and reliable level measurement for various tanks.
The SeeLevel II system monitors tank levels (Fresh, Grey, Galley, Black, and LPG), battery voltage, and offers diagnostic capabilities. It uses flexible self-adhesive sender panels attached to the side of holding tanks, which auto-calibrate to the tank's height. The display unit receives information from these senders via a two-conductor wire and shows levels in percent on a 3-digit LED display.
