OUT_SCALE:
Sets the range of output (from 0% to 100%).

available units for out_SCaLE are the table
5.16 units for XD_SCaLE.

L_TyPE:
Specifies the operation function of the aI

blocks. the factory default is “Direct”, so the
input delivered to CHannEL is directly re-
flected on out. If set to “Indirect”, scaling by
XD_SCaLE and out_SCaLE is carried out
and is reflected on out. “Indirect SQRt” is not
used for RotaMaSS.

PV_FTIME:
Sets the time constant of the damping function

within the aI blocks (primary delay) in seconds.

Alarm Priority:
Indicates the priority of the process alarm. If a

value of 3 or greater is set, an alarm is trans-
mitted. the factory default is 0. Four types of
alarm can be set: HI_PRI, HI_HI_PRI, Lo_PRI,
and Lo_Lo_PRI.

Alarm Threshold:
Sets the threshold at which a process alarm

is generated. the factory default setting is a
value that does not generate an alarm. Four
types of alarm can be set: HI_LIM, HI_HI_LIM,
Lo_LIM, and Lo_Lo_LIM.

5.6.5 Transducer Block Parameters

the transducer block sets function specific to the
flow rate measurement of the RotaMaSS. For a
list of block parameters in each RotaMaSS, refer
to appendix 1, “List of Parameters for Each Block
of RotaMaSS.” the following describes impor-
tant parameters and how to set them.

Parameters for Zero Tuning

1) AUTO_ZErO_TIME

(relative Index 69)
Defines the duration of the auto zero func-
tion as follows:

1 = 3 Minute

2 = 30 Seconds

2) AUTO_ZErO_EXE

(relative Index 70)
Starts the auto zero function to be per-
formed as follows:

1 = not Execute

2 = Execute

Parameters for Primary Variable

3) MASS_FLOW_VALUE_FTIME

(relative Index 27)
Defines the damping time constant for the
mass flow rate to be input to the flow rate
calculation.

Setting range: 0.1 to 200 (seconds)

Default: 3 (seconds)
