they drape over the sender they could affect the reading.
each sender to ground at the display. It is very important that
the display and the senders have the same ground. Use crimp
on butt connectors to fasten the wires together.
13. 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. Refer to
the enclosed wiring diagrams.
14. 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 single or double sender system for each tank.
See the chapter entitled "DISPLAY CALIBRATION" and the
section "To program the number of senders for each tank"
for details. Make sure you do it for each tank.
15. For the initial test, have the tank at least
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 at least 20%
(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. The gauge will work with maximum signal
strengths as low as 20%, but it is good to have at least 50% to
60% at installation so that there is some margin available for
buildup in the tank. Note that the system "learns" about the
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
