Countermeasure
AL. 01
CAP.ERR
Sensor problem. Outputs the signal (High or Low) set
with burnout direction switch.
[status output: undefined]
Replace capsule if the error recurs
after the transmitter is restarted.
Capsule temperature sensor problem. Replace capsule.
Capsule EEPROM problem.
AL. 02
AMP.ERR
Amplifier temperature sensor problem. Replace amplifier.
Amplifier EEPROM problem.
Amplifier problem.
A/D Converter problem.
AL. 03
ET.ERR
External temperature sensor
disconnection.
Check external temperature sensor.
— No device ID is found. Continues to operate and output. Replace amplifier.
AL. 10
PRESS
Differential pressure is outside
measurement range limit of capsule.
When PV is Pres
Output AO upper limit or AO Lower
limit.
Check input or replace capsule when
necessary.
AL. 11
ST. PRSS
Static pressure exceeds limit. When PV is SP
Output AO upper limit or AO Lower
limit.
AL. 12
CAP.TMP
Capsule temperature is outside range
(–50 to 130°C).
Continues to operate and output. Use heat insulation or make lagging
to keep temperature within range.
AL. 13
AMP.TMP
Amplifier temperature is outside range
(–50 to 95°C).
AL. 14
EXT. TMP
External temperature is outside range. When PV is ET
Output AO upper limit or AO Lower
limit.
AL. 15
EXT. TMP
External temperature sensor resistance
is out specification.
AL. 16 PLS Pulse output is out specification. Continues to operate and output. Check settings and change them.
AL. 30
PRS.RNG
Differential pressure exceeds specified
range.
When PV is Pres.
Output AO upper limit or lower limit.
Check input and range setting, and
change them as needed.
AL. 31
SP. RNG
Static pressure exceeds specified
range.
When PV is SP
Output AO upper limit or lower limit.
AL. 32
F. RNG
Flow exceeds specified range. When PV is Flow
Output AO upper limit or lower limit.
AL. 33
ET. RNG
External temperature exceeds specified
range.
When PV is ET
Output AO upper limit or lower limit.
AL. 35 P.HI Input pressure exceeds specified
threshold.
Continues to operate and output. Check input.
AL. 36 P.LO
AL. 37 SP.HI
Input static pressure exceeds specified
threshold.
AL. 38 SP.LO
AL. 41 F.HI
Input flow exceeds specified threshold.
AL. 42 F.LO
AL. 43 ET.HI
Input external temperature exceeds
specified threshold.
AL. 44 ET.LO
AL. 50 P. LRV
Specified value is outside of setting
range.
Holds at the output value that existed
immediately before the error occurred.
Check settings and change them as
needed.
AL. 51 P. URV
AL. 52 P. SPN
AL. 53 P. ADJ
Continues to operate and output. Adjust settings and change them as
needed.
AL. 54
SP. RNG
Holds at the output value that existed
immediately before the error occurred.
Check settings and change them as
needed.
AL. 55
SP. ADJ
Continues to operate and output. Adjust settings and change them as
needed.
AL. 56
ET. RNG
Holds at the output value that existed
immediately before the error occurred.
Check settings and change them as
needed.
AL. 57
ET. ADJ
Continues to operate and output. Adjust settings and change them as
needed.
AL. 58
FL. ADJ
Holds at the output value that existed
immediately before the error occurred.
Check settings and change them as
needed.
AL. 59
PLS.ADJ
Specified value is outside of setting
pulse output.
Normal calculation.
— Under Temperature Fix Mode. PV is ET Temp. Output Fix at 4mA. Leave from Temperature Fix Mode.
