Installation and operating instructions
19 ALTOSONIC III
3.10.01 DIG OUTPUT Function of digital status output
CUST ERR (Only errors related to custody transfer operation, also see error list)
ALL ERR (indication of all errors)
F/R IND (forward/reverse flow indication)
OVERRANGE (overrange indication)
TRIP POINT (trips when actual flow (Q) goes over a set limit, see 3.10.02 and 3.10.03 for settings)
3.10.02 TRIP PNT 1 First trip point
Range: 0 through 120% of Q100%
3.10.03 TRIP PNT 2 Second trip point
Range: 0 through 120 % of Q100%
4.00.00 PARAM ERR Main menu 4.00.00 Parameter error
4.01.00 FLOW VELOC Volume flow velocity (v) value incorrect. The flow speed is calculated from the full scale volume flow and
the meter size.
Ensure condition 0.5 m/s
≤ v ≤ 20 m/s (1,5 to 66 feet/s) is met!
4.01.01 FULL SCALE Full-scale value for 100% volume flow rate, see Function 3.01.01
4.01.02 METER SIZE Meter size, see Function 3.01.08
4.02.00 CURR OUTP Current output range incorrect. Setting for 100% is compared with setting for 0%. Ensure condition 100
pct-0 pct
≥
4 mA is met!
4.02.01 RANGE Range of current output, see Function 3.04.03
4.02.02 0 pct Current value for 0% scale, see Function 3.04.04
4.02.03 100 pct Current value for 100% scale, see Function 3.04.05
4.03.00 LF CUTOFF Low-flow cut-off range incorrect: If low flow cut-off is set to on, the value for CUTOFF-OFF is compared
with the value of CUTOFF-ON on.
Ensure condition CUTOFF-OFF – CUTOFF-ON
≥
1% is met!
4.03.01 LF CUTOFF Low-flow cut-off, see Function 3.01.05
4.03.02 CUTOFF ON Cut off “on” value, see Function 3.01.06
4.03.03 CUTOFF OFF Cut off “off” value, see Function 3.01.07
4.05.00 PULSE/VOS Unit of pulse output for velocity of sound function incorrect
Ensure "PULSE RATE" is selected for "VOS"!
4.05.01 PULS FUNCT Function of pulse output, see Function 3.05.01
4.05.02 PULSE OUTP Unit of pulse output, see Function 3.05.07
4.06.00 VOS Velocity of sound range incorrect:
Ensure condition MAX VOS - MIN VOS
≥
1 m/s (3.3 ft/sec) is met
4.06.01 MIN VOS Minimum velocity of sound, see Function 3.01.11
4.06.02 MAX VOS Maximum velocity of sound, see Function 3.01.12
4.07.00 PULSE OUTP Pulse output frequency value (f) incorrect. The max frequency is calculated from the pulse/unit setting
and the max value of the measured value.
Ensure condition 1 pulse/hr
≤ f ≤ 2000 pulse/s is met.
4.07.01 PULSE/UNIT Pulse value for volume flow rate unit, see Function 3.05.09
4.08.00 PULS WIDTH Pulse output pulse width incorrect
Ensure condition pulse width
≤
0.5 x pulse period time is met.
4.08.01 PULS WIDTH
Pulse width for frequencies
≤
10 Hz, see Function 3.05.11
4.09.01 CURR RANGE Range of current output, see Function 3.04.03
4.09.02 CURR 0 pct Current value for 0% scale, see Function 3.04.04
4.10.00 INP/OUTP The digital input (C) and current output (I) are not allowed to be switched on simultaneously. The current
output is deactivated by setting the function of current output to off en setting the range of current output
to 0-20mA.
4.10.01 INP FUNCT Function of digital input, see Function 3.06.01
4.10.02 CURR FUNCT Function of current output, see Function 3.04.01
4.10.03 CURR RANGE Range of current output, see Function 3.04.03
4.10.04 PULS FUNCT Range of pulse output, see Function 3.05.01
4.13.00 EPROM EPROM checksum error, reset device.
