TYPE and Unit
: Displaying full range and unit of Input Sensor type configured in ‘AI SET’
screen.

PV RANGE
Display and Setup
z
PV low/high range is to limit the input from sensor and the limit range is
+/- 5%
of total PV
low/high range and the out range of
+/- 5%
is displayed by OVER or UNDER.
z
If the sensor type in AI SET(Section 3.3) is changed, PV low/high range also is changed to
total range of the sensor type automatically.
z
Low range of sensor type < PV LOWER < SP LOWER,
SP UPPER < PV UPPER < High range of sensor type
(4)
SP RANGE
Display and Setup
z
Limits user’s set input like Target Set Point of Fix control or Segment etc.
z
If the sensor type in AI SET(Section 3.3) is changed, SP low/high range also is changed to
total range of the sensor type automatically.
z
PV LOWER < SP LOWER < SP UPPER, SP LOWER < SP UPPER < PV UPPER

Square Root
computation(extraction)
z
Pressing function selection ON/OFF button selects/cancels square root operation.
Default = OFF
(5-1)
LOW CUT
: sets the conversion limit value to input
z
Linear Value is applied when under set value, and the equation below is applied
when over the set value.
range = 0.0~5.0%(of input range)
