FLG. HI
M
Flg Temp High
Alarm (AL-87)
Module-1: Flange
temperature exceeds
the specified upper limit
threshold. (AL87)
Follows the Diag Out
Option settings.
Off:
Continues to output
the current value.
Burnout:
Shifts the output to
the AO upper limit
or AO lower limit
parameter value.
Fall back:
Outputs the value
specified by the
Diag Fixed Out Val
parameter.
1) Check heater
malfunction and
disconnection.
2) Check the capsule
temp. and amplifier
temp.
3) Adjust flange
temperature
coefficient(Flg temp
coef).

(AL-88)
Differential pressure
fluctuation does not
reach the reference level
required to blockage
detection so that no
blockage detection is
carried out.(AL-88)
Continues to output
the current value.
1) Check process
condition.
2) Obtain the reference
fluctuation values
again.

B Blocking
(AL-89)
B blocking (both-side
blockage) has been
detected. (AL-89)
Follows the Diag Out
Option settings.
Off:
Continues to output
the current value.
Burnout:
Shifts the output to
the AO upper limit
or AO lower limit
parameter value.
Fall back:
Outputs the value
specified by the
Diag Fixed Out Val
parameter.
1) Check the process
and impulse line
conditions.
2) If there are large
flow change or the
change of fluid under
the measured process
conditions, obtain the
reference value again.
