Explanation
43 2043 LIMSW_2 _
HYSTERESIS
0 O/S Sets the hysteresis of limit switch 2 to be applied
for resetting the LIMSW_2_VALUE_D to OFF after
LIMSW_2_TARGET went beyond LIMSW_2_SETPOINT
and LIMSW_2_VALUE_D turned ON (when used as a
high-limit switch), or after LIMSW_2_TARGET went below
LIMSW_2_SETPOINT and LIMSW_2_VALUE_D turned
ON (when used as a low-limit switch).
44 2044 LIMSW_2_UNIT — — Indicates the unit set in LIMSW_2_TARGET.
45 2045 ALARM _PERFORM 0x1070 AUTO A series of bits, each of which works as a switch to
enable and disable specic alarm(s); write zeros to the
respective bits in this parameter to disable desired alarms.
(For details, read APPENDIX 3 "OPERATION OF EACH
PARAMETER IN FAILURE MODE.")
46 2046 ARITHMETIC
_BLOCK
1 (Available) — Indicates whether the arithmetic block is available.
47 2047 SENSOR_STATUS — — Indicates whether the ow detector has the built-in
temperature sensor:
1 = Standard
2 = Built-in Temp. Sensor
48 2048 THERMOMETER

operating conditions. Setting range: 0.00001 to 32000
56 2056 PRESSURE_UNIT MPaa (1545) (Note 5) O/S Selects the unit of pressure between 1545 (= MPaa) and
1547 (= kPaa).
57 2057 PROCESS _
PRESSURE
0.1013 (Note 5) O/S Sets the normal operating absolute pressure of the
process. Setting range: 0.00001 to 32000
58 2058 BASE _PRESSURE 0.1013 (Note 5) O/S Sets the absolute pressure under the standard conditions
of the process. Setting range: 0.00001 to 32000
59 2059 DEVIATION 1 (Note 5) O/S Sets the deviation factor of the process uid. Setting range:
0.001 to 10.0
60 2060 SECONDARY
_VALUE_FTIME
4 s AUTO Sets the time constant of damping for the temperature
calculation. Setting range: 0 to 99 s
61 2061 CABLE_LENGTH 0 O/S Sets the length of cable between the ow detector and
remote amplier. Set 0 for an integral type digitalYEWFLO.
Setting range: 0 to 30 (meters)
62 2062 FIRST_TEMP
_COEF
