4-20highlimit(J12)]isnotsatised.
CheckwhetherparametersJ11and
J12arecorrect.
55:Multi Rng Err Check parameter F30 to F34 {F36} The condition [No. 1 range < No. 2
range < No. 3 range < No. 4 range] is
notsatisedformultipleranges.
Check whether parameters F30
through F34 {F36} are correct.
56:H/L HH/LL Set Check parameter G10 to G14 The condition [High Alarm (G11) – Low
Alarm (G10) > H/L Alarm Hys (G14)]
or the condition [High High Alarm
(G13) – Low Low Alarm (G12)
>H/LAlarmHys(G14)]isnotsatised.
Check whether parameters G10
through G14 are correct.
57:Dens Set Err Check parameter C40, C45, and C46 Mass units have been selected for
Base Flow Unit (C40) but density is
set to 0.
Check whether parameters C40, C45,
and C46 are correct.
60:PLS > 10000p/s Check parameter E10, E11, and E12 Pulse rate is 11000 pps or more with
50% duty selection.
Pulse rate is 10000 pps or more with
0.05 ms selection.
Check whether parameters E10, E11,
and E12 are correct.
61:PLS > 5000p/s Check parameter E10, E11, and E12 Pulse rate is 5000 pps or more with 0.1
ms selection.
62:PLS > 1000p/s Check parameter E10, E11, and E12 Pulse rate is 1000 pps or more with 0.5
ms selection.
63:PLS > 500p/s Check parameter E10, E11, and E12 Pulse rate is 500 pps or more with 1
ms selection.
64:PLS > 25p/s Check parameter E10, E11, and E12 Pulse rate is 25 pps or more with 20
ms selection.
65:PLS > 15p/s Check parameter E10, E11, and E12 Pulse rate is 15 pps or more with 33
ms selection.
66:PLS > 10p/s Check parameter E10, E11, and E12 Pulse rate is 10 pps or more with 50
ms selection.
67:PLS > 5p/s Check parameter E10, E11, and E12 Pulse rate is 5 pps or more with 100
ms selection.
70:PLS<0.0001p/s Check parameter E10, E11, and E12 Pulse rate is 0.00005 pps or less.
71:Meas Mod Set Check parameter C20 Measure Mode (C20) is set to
Enhanced DF without selecting an
optional code HF1 or HF2.
Check whether parameter C20 is
correct.
72: Size Set Err Check parameter C32 A value of 3000.1 mm or more is set
for Nominal Size (C32).
Check whether parameter C32 is
correct.
73: Adh Set Err Check parameter K11 to K14 The condition in Adhesion detection
level, Level:1<Level:2<Level:3<Level:4
isnotsatised.
Check whether parameters K11, K12,
K13 and K14 are correct.
80:Adhesion Wng
–
Slight adhesion to electrodes. Clean and check the electrodes. Refer
to parameter K13.
82:Auto Zero Wng
–
Results of automatic zero adjustment
are higher than the rated values.
Carry out adjustment as follows:
• Check if the flowtube is filled with
uid.
• Check if the flow velocity is
completely zero.
• Check the condition of grounding.
83:Fix Cur Wng
–
Thecurrentvalueisxed. Confirm whether the flow rate is in
excess of the upper limit (108%) or
below the lower limit (-8%), or whether
upon entry to the Test Mode or not.
84:Disp Over Wng
–
Overflow in the display digits during
instantaneousowratedisplay.
Check whether parameter C43 is
correct.
90:Disp SW Wng (only for display unit)
–
Display unit switches are not
operating.
Investigate whether the display unit
cover is fitted or whether the cover’s
glass surface is dirty.
Note: In case of the AXFA11 Remote Converter, parameter number is values in brackets { }.
