A2.2 Setting and Change

of Basic Parameters

this section describes the procedure taken to set
and change the parameters for each block. ob-
taining access to each parameter differs depend-
ing on the configuration system used. For details,
refer to the instruction manual for each configura-
tion system.

access the parameter to be set or changed.

Make setting or change in accordance with
each parameter.

Set the target of block mode (MoDE_BLK)
back to auto

(*note 2)

.

access the block mode (MoDE_BLK) of each
block.

Fa0201.EPS

Set the target

(*note 1)

of block mode

(MoDE_BLK) to auto, Man or o/S

(*note 2)

according to the Write Mode of the parameter
to be set or changed.

note 1: Block mode consists of the following four modes that

are controlled by the universal parameter that displays
the running condition of each block.
target: Sets the operating condition of the block.
actual: Indicates the current operating condition.
Permit: Indicates the operating condition that the block

is allowed to take.

normal: Indicates the operating condition that the block

will usually take.

note 2: the followings are the operating conditions which the

individual blocks will take.

A2.3 Setting the AI Func-

tion Blocks

Each RotaMaSS contains six aI function blocks
(aI1 to aI6) having independent parameters.Set
up the parameters of each aI block you use, indi-
vidually as necessary.

The AI1 block performs the mass flow rate
output calculation
.

(1)-1. Setting the calibration range

FA0202.EPS

Access the XD_SCALE parameter.

Set the required unit in Unit Index of
XD_SCALE.
Set the upper range limit in EU at 100% of
XD_SCALE.
Set the lower range limit in EU at 0% of
XD_SCALE.

Example:
to measure 0 to 100t/h,
Set t/h (1328)*

1

in units Index of XD_SCaLE,

Set 100 in Eu at 100% of XD_SCaLE, and
Set 0 in Eu at 0% of XD_SCaLE.

(1)-2. Setting the output scale

FA0203.EPS

Access the OUT_SCALE parameter.
Set the required unit in Unit Index of OUT_SCALE.

Set the output value corresponding to the upper
range limit in EU at 100% of OUT_SCALE.
Set the output value corresponding to the lower
range limit in EU at 0% of OUT_SCALE.

Example:
to set the output range to 0.00 to 100000.00kg/h,
Set kg/h( 1324)*

1

in units Index of out_SCaLE,

Set 100000 in Eu at 100% of out_SCaLE,

Set 0 in Eu at 0% of out_SCaLE.

The AI2 block performs the volume flow out-
put calculation.

(2)-1. Setting the calibration range

FA0202.EPS

Access the XD_SCALE parameter.

Set the required unit in Unit Index of
XD_SCALE.
Set the upper range limit in EU at 100% of
XD_SCALE.
Set the lower range limit in EU at 0% of
XD_SCALE.
