AUTO
Priority of the low alarm. 0, 1, 3 to 15
30
4030 4130 4230 LO_LIM
-1. #INF
AUTO
The setting for the low alarm in engineering units.
(Note 2)
31
4031 4131 4231 LO_LO_PRI
0
AUTO
Priority of the low low alarm. 0, 1, 3 to 15
32
4032 4132 4232 LO_LO_LIM

(Note 2)
33
4033 4133 4233 HI_HI_ALM
—
The status for high high alarm and its associated time
stamp.
34
4034 4134 4234 HI_ALM
—
The status for high alarm and its associated time
stamp.
35
4035 4135 4235 LO_ALM
—
The status of the low alarm and its associated time
stamp.
36
4036 4136 4236 LO_LO_ALM
—
The status of the low low alarm and its associated time
stamp.
37
4037 — 4237 TOTAL
0
—
Indicates the totalized fl ow rate.
38
4038 — 4238 TOTAL_START
1 (Stop)
AUTO
Starts/stops the totalizer.
39
4039 — 4239 TOTAL_RATE_VA 1
O/S
Totalization rate (Note 4)
40
4040 — 4240 TOTAL_RESET
1 (Off)
AUTO
Resets the totalized fl ow rate. This parameter value
reverts to 1 (Off) after it has been set to 2 to perform
resetting.
Note 1: An intended set value can be written only if Min(OUT_SCALE.EU0, OUT_SCALE.EU100)
≤ the intended value ≤ +INF.
Note 2: An intended set value cannot be written if –INF
≤ the intended value ≤ Min(OUT_SCALE.EU0, OUT_SCALE.EU100).
Note 3: Indicates the corresponding data for the temperature.
Note 4: The setting range of TOTAL_RATE_VAL is above 0 and its unit is determined by the setting in the Units Index element of XD_
SCALE. For example, if m
3
/h is set in Units Index of XD_SCALE, then the unit of TOTAL_RATE_VAL is m
3
/p (square meters per
pulse), or if kg/s is set in Units Index of XD_SCALE, the unit of TOTAL_RATE_VAL is kg/p. Nevertheless, for TOTAL_RATE_VAL,
set a power of ten such as 0.1, 1, 10, or 100. If any other number is set, the totalizer reading on the LCD indicator shows the
totalized pulse count without the unit.
