GARNET 710-JS Holding Tank Monitor User Manual

INTRODUCTION

The SeeLeveL Senders 710-JS, 710-ES, 710-SS are used with SeeLeveL II Tank Monitoring systems that can monitor either two, three or four tanks.
The 710-JS sender is 6″ high (not including tabs) and has a resolution of 1/4″. This model can measure tanks from 5″ to 7.5″ high tanks and cannot be stacked. The higher resolution is optimal for low-profile tanks.
The 710-ES sender is 12″ high (not including tabs) with a resolution of 3/8″ and can measure tanks from 5.5″ to 14″ high with a single sender, and up to 26″ with double-stacked senders.
The 710-SS sender is 16″ high (not including tabs) and has a resolution of 1/2″. This model can measure tanks from 7″ to 18″ high with a single sender, and up to 34.5″ with double-stacked senders.
The senders are mounted on the outside of the holding tanks and can be stacked to fit taller tanks. They work on most plastic or polyethylene holding tanks that contain water-soluble fluids. They are not compatible with metal holding tanks. See more information about sender lengths on page 3.
The communication protocol used between our senders and displays is proprietary allowing us to control the accuracy and functionality of our systems ensuring our customers experience reliable operation.

The installation for the complete system consists of mounting the display inside the RV, cutting and mounting the senders to the sides of the tanks, connecting the wiring, and programming the display.
This manual provides information on how to install the SeeLeveL 710-JS, 710-ES, and 710-SS senders.
NOTE: The new 710-AR, 710-ES2 can be combined with old sender models 710-ES, 710-JS, 710-SS.

Before senders are installed the display should be installed first.

Refer to the Display Installation Guide and User Manual for the model you’ve purchased for all installation and connection details. Manuals can be found at our online Resource Library from our website at: http://https://www.garnetinstruments.com/holding-tanks-resource-library/

Tools and equipment required:

• Wire cutters/stripper
• Wire crimper
• Scissors or hole punch
• Acetone/rubbing alcohol
• Duct tape or tie-wraps for securing wires
• Non aggressive tape (painters, masking)
• Electrical tape
• Butt connectors

DETERMINE BEST CONFIGURATION & LOCATION

The senders will need to have a flat area on the side of the tank large enough so the whole width of the sender is in contact with the side of the tank.
Make sure that any metal is at least 1” away from either side, top and bottom of the sender, and at least 2” away from the face of the sender.
Some tanks may have irregular shapes. DO NOT
wrap the corners over the top or bottom of the tank.
See placement examples to the right.

Sender Configuration

To determine which sender configuration you need, measure the height of your tanks, then find out the measurable space (see following page). The measurable space is the “ideal” position of the sender on the tank. This will determine what length the senders should be. If a sender is too long, it will need to be cut. The following table has recommended senders and configurations for various tank heights.

CAUTION: Bending the sender sharply will damage the circuit on the sender.

DETERMINE MEASURABLE SPACE ON TANKS

Find Measurable Space

Measure the height of the tank from top to bottom then determine measurable space.

• The minimum gap is 1/4″, however, we recommend that the senders be installed 1/2″ from the top and 1/2″ from the bottom of the tank. Depending on the characteristics of the tank the gap can be a little more or less (see note below and installation tips on page 12). This gap ensures that the sender can read properly through the tank wall as the corners or rounded edges of the tanks can be too thick for the sender to read through.
• Subtract the gap space from the overall tank height. This will result in your measurable space. Use the calculation formula at the right

CAUTION: Installing a sender outside of the recommended measurable space may affect your readings.

Single configuration

1. Measure the height of the tank.
2.  Tank height = __
3.  Calculate the recommended measurable space as follows:
   Tank height − top gap − bottom gap = measurable space. *See note regarding gap recommendations.

NOTE: If senders do not fit full height of the tank, to optimize the level you can justify sender location to be either closer to the top or bottom, depending on the type of liquid (Fresh or Grey/Black).
FRESH = closer to bottom as it is preferable that this tank is not empty!
GREY/BLACK = closer to top as it is preferable that these tanks are not full!

Stacked configuration

Two senders may be required for taller tanks and additional senders may be purchased for this application. There needs to be a gap of 1/16” to 1/8” between the double stacked senders.
Calculate what the total length of measurable space for both senders will be:

1.  Measure the height of the tank.
2. Tank height = __
3. Calculate the recommended measurable space
4. Tank height − top gap − bottom gap − middle gap = measurable space. *See note regarding ap recommendations.\\\

SENDER SPECIFICATIONS

CUTTING SENDERS

The senders need to be cut to the required length to match the height of the measurable space of the tank.
The cut must be between the sender segmented pads. Senders have a minimum length they can be cut. The minimum length for the 710-ES and 710-SS is after the first three segmented pads and the 710-JS minimum is four segmented pads. Once this has been determined, cut the sender with a pair of scissors.

\

PROGRAMMING THE SENDERS

Senders are programmed by cutting off the tabs at the top of each sender to tell it which tank it will be mounted on, or if in a stacked configuration, whether they are on the top or bottom. A pair of scissors or a hole punch can be used to cut the sender tabs.
The senders can be programmed for FRESH, GREY, BLACK, and GALLEY tanks. The tabs are labeled at the top to show you which tab or tabs to cut for which tanks. Cut the middle tab labeled “TOP” for double-stacking senders (top sender only).

For examples of programming for each tank types refer to the table

at the bottom and the illustrations on the next page

PROGRAMMING THE SENDER 710-JS

PREPARE SENDER FOR INSTALLATION

Clean the tank

Clean area throughly where the sender will be mounted making sure there is no dust, grease and oil.
Acetone or rubbing alcohol will remove sticky residue.

❷ W CAUTION: Route wires to the right, away

Once the sender is cut and programmed, temporarily tape the sender to the tank wall. Place a piece along the length of both sides of the
sender and perform a test to verify operation.

WIRING THE SENDER

Connect the wiring to the pigtail
The following diagram shows the wiring from the sender to the display pigtail. Other wiring connections may apply for each display model. All wiring diagrams are available on the website.

SENDER TEST

Verify operation before permanently sticking the sender to the tank.

Permanently adhere sender to the tank

Secure the wires

Secure the wires with duct tape, tie wraps, or something similar so that the wires do not rattle or press against the sender, this may result in sender
damage or wires breaking over time

Apply undercoating to the senders
On installations where the holding tank is exposed to under chassis road spray and flying rocks etc. We recommend the use of a rubberized undercoating.
Recommended brands: 3M 03584 Professional Grade Rubberized Undercoating
Gravel Guard Rocker Guard Coating By Dominion Sure Seal
