Error descriptions
In case of errors the display of the
DigiFlow 515
toggles between normal display and error display in Fre-
quency of 1 s. The beeper sounds alternately.
The beeper can be stopped by pressing the ENTER-key during on change to error display. The beeper is
then quiet until a new error condition occures.
All errors are not stored and releases when the error conditions ends.
The meaning of these errors are:
Analog #1
I
in
< 3.6mA or I
in
> 22mA.
Analog #2
Same as Analog #1, but only when this input is used..
Analog #3
Same as Analog #1, but only when this input is used.
Analog #4
Same as Analog #1, but only when this input is used.
Pt100 #1
R
pt100
< 20 Ohms or R
pt100
> 390 Ohms, but only when input is used.
Pt100 #2
Same as Pt100 #1
Redundanz
When selected 2 redundant analog flow inputs, the allowed maximum difference exeeded.
Bel. sat. line.
Can only occur on Steam-Computers, and when during factory setting the calculation of
water is disabled in the forward path. The calculator then calculates on the saturation line,
determined by temperature input.. (This shall inhibit the enormous massflow output, when
in errorous case water as flow medium is determined, when by tolerances of the sensors
the tempature or pressure is below the saturation line.)
