13. Connect the all the blue wires from the senders together, and to the blue
wire from the display. Connect the black wire from each sender to ground.
Use Marrette or crimp connectors to fasten the wires together. Make sure
that the wires from the sender are routed away from the sender, if they
drape over the sender they could affect the reading. Secure the wires with
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.
14. Do steps 4 to 12 for the other holding tanks.
15. All that remains now is calibration and testing. The tank senders will self
calibrate to whatever length they are cut, so they will always read from 0 to
100%. The display needs to be set to a one or two sender system for each
tank. See the chapter entitled "DISPLAY CALIBRATION" and the section
"To calibrate the number of senders for each tank" for details. Make
sure you do it for each tank.
16. For the initial test, have the tank at least 1/4 full of water or sewage, and
verify that the percent level reading looks correct (see the chapter entitled
"OPERATING INSTRUCTIONS" and the section "To read a water or
sewer tank level" for details). Check to see that the signal power is
adequate (see the chapter entitled "TROUBLESHOOTING GUIDE" and
the section "To review the sender diagnostics" for details). If the signal
power is too low, make sure that the sender(s) is well stuck to the side of
the tank and that the tank is reasonably clean inside, as a large buildup will
reduce signal strength.
characteristics of the tank with use, so the readings may be inaccurate
when the tank is empty or almost empty when the system is first tested.
Once the tank has been filled at least 1/4 full the system will be properly
"taught" and should read correctly after that.
17. Calibrate the LPG by filling the tank and following the instructions in the
chapter entitled "DISPLAY CALIBRATION" and the section "To calibrate
the LPG sender".
18. Connect the pump switch as required.
WARNING: The pump switch is rated for a maximum of 6 amps. The use
of a relay is required if more than 6 amps is needed.
19. 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.
Note that the system "learns" about the
