POINT
(1) Do not input more than ±15V. The element may be damaged.
(2) If the analog input provided corresponds to the digital output value* beyond its
range, the digital output value is fixed to the maximum or minimum.
For 0 to 4000, the digital output value is within the range -96 to 4095.
For -4000 to +4000, the digital output value is within the range -4096 to +4095.
(3) Within the analog input and digital output scopes of each input range, the
maximum resolution and accuracy are within the performance specification
range. Outside those scopes, however, they may not fall within the performance
specification range. (Avoid using the dotted line part in Fig. 3.1.)
(4) Set the offset and gain values of the user range setting within the range
satisfying the following conditions.
(a) Setting range when user range setting 1 is selected: -10 to +10V
(b) Setting range when user range setting 2 is selected: 0 to 5V
(c) (Gain value) > (Offset value)
If you attempt to make setting outside the setting range of (a) or (b), the "RUN"
LED flickers at 0.5s intervals.
Set the values within the setting range.
If you attempt to make setting outside the setting range of (c), the "RUN" LED
flickers at 0.5s intervals.
Make setting again.
