DI Assignment of LSP group selection

The LSP group selection can be set for internal contacts 1 to 3 using the DI
Assignment.

• Details of LSP group selection with the internal contact function

The following shows the LSP group selection value according to the ON/OFF
status of each internal contact:

LSP group selection (0/+1)

OFF: 0

ON: 1

LSP group selection (0/+2)

OFF: 0

ON: 2

LSP group selection (0/+4)

OFF: 0

ON: 4

The value, that "1" is added to the sum of the LSP group selection values
according to the ON/OFF status of each internal contact, becomes the LSP group
number.
For example, when the sum of LSP group selection values of internal contact 1 to
3 is "1", the LSP group number becomes "2".

• Even though the LSP system group is "1", the display and setting can be made,

but the LSP group selection with the internal contact function becomes invalid.

■

SP ramp unit

The unit of the SP up/down ramp can be set.

• "0.1U" shows that the decimal point position of the PV is shifted one digit

rightward.

Example: When the thermocouple input is in a range of -200 to +1200˚C, "0.1U"

is "0.1˚C ".

Example: When the DC voltage input is in a range of 0.0 to 100.0, "0.1U" is

"0.01".

Handling Precautions

When using the DC voltage/DC current input with setting of 3 digits

after the decimal point, "0.1U" is "0.0001".

However, the SP up ramp/SP down ramp setting cannot display 4

digits after the decimal point, the value is displayed without use of the

decimal point.
