ABOUT THE SYSTEM

The Senders
Each sender panel is a flexible self-adhesive printed circuit board which is
adhered to the side of the holding tank. The sender panel can be cut to length
to match the height of the tank, and it auto calibrates itself so that it can read
from Empty to Full regardless of the height of the tank.
In addition to the level, the sender also transmits diagnostic information about
its operation. This information can be used to determine if there is buildup of
sludge on the inside of the tank, or to determine if the sender is damaged or
delaminating from the side of the tank. If sludge buildup in the tank becomes
extreme the gauge will cease to operate properly, so by monitoring the signal
power the tank can be cleaned before the buildup gets excessive.
Multiple senders are available with the ability to double stack the senders to
provide accurate level measurement for tank heights ranging from 4" to 25".

The Display
The display receives the information from sender panels via a single 2 conductor
wire and shows the level information in percent of full on a 3-digit LED display,
from 0% to 100%. When the button for a particular tank is pressed, the display
shows the level for that tank.
Battery Voltage
The system also shows the RV battery voltage by measuring the voltage which
powers the display. The voltage is shown with a resolution of 0.1 volt.
Diagnostics
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, cut, or if the sender panel is defective, then the display will indicate
an error code. The various error codes are shown in the section entitled
"TROUBLESHOOTING GUIDE".
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, servicing is greatly aided with
the diagnostic information.

LPG (if equipped)
The display can use an existing LPG electrical sender to show the LPG level. It
can be automatically calibrated to any sender and shows the level information
in percent of full on a 3-digit LED display, from 0% to 100%.
Bluetooth® (if equipped)
The display has Bluetooth® wireless technology, which allows you to check
your tank levels, battery voltage, and LPG tank levels on any compatible
smartphone or tablet device with a free downloadable app available on both
iTunes and Google Play. This model include one alarm output which can be
used to signal a high or low water or sewer level as required.
(See separate manual for app installation and operation-link on page 4)
RV-C (if equipped)
Models equipped with RV-C are compatible with RV's that have an RV-C
network system. These models include one alarm output which can be used to
signal a high or low water or sewer level as required.
Different Display Types (If equipped)
Displays with RV-C, Bluetooth, or Alarms operate differently from displays
without these features. In order to keep the tank level and alarm information
current, these displays regularly scan the senders every 10 to 15 seconds. When
a tank button is pressed, the information displayed is recalled from the most
recent scan. A tank on hold is scanned more frequently. Systems with two
displays are configured so that the primary display initiates the scanning and
the secondary display passively listens to the sender information, this way both
displays stay updated without interfering with each other.
Alarm Output (If equipped)
The single common alarm output can be programmed to indicate a high or low
sewage level, a high or low water level, or a high or low LPG level. More than
one alarm can be assigned to the alarm output. This output can be connected
to an indicator light and used to show a high sewer level and/or a low water
level, alerting the user that attention is required. Another example is the alarm
could be used on the black tank to prevent toilet use when the tank is full.
NMEA 2000 Network (If equipped)
Model 709-N2K NLP is NMEA 2000 Network compatible, the tank levels and
capacity are available on the NMEA Bus.
