SYMPTOM CAUSE ACTION
MultiRanger Plus will not
respond to programmer
programmer improperly
positioned
infrared window
obstructed
programmer battery low
refer to installation
clean
test programmer P-95
Reading erratic echo confidence weak refer to P-85, 86 87 & 88
liquid surface agitated increase damping,
P-68 & 69,
turn on fuzz filter P-72
material filling relocate transducer *
increase damping,
P-68 & 69
electrical noise check P-84 under
quiescent conditions, noise
should be under 15 dB
transducer cable must be
in grounded metal conduit
and cable grounded only
at TB-1 *
increase damping,
P-68 & 69
agitator blades set P-73 to 1
Reading ‘EEEE’ reading to large re-calibrate,
i.e. P-3, 4, 37, 52 & 53
Reading response slow damping to high increase P-68 & 69
agitator on turn off P-73
fuzz filter on turn off P-72
Reads correctly but
occasionally reads high
when vessel is not full
detecting close range echo
or ringing
increase blanking
increase short
measurement threshold,
P-81
transducer mounting *
High level reading lower
than material level
material is within near
blanking zone ( P-5 ).
Echo multiple being level
processed
decrease blanking limit
material high
*
refer to associated transducer manual
