7.1.5 Burnout Detection
UP or DOWN can be selected as the measured value when the burnout error occurs.
When a burnout is detected, the measured value becomes 105.0% of the input range
when up scale is set and -5.0% of the input range when down scale is set.
The burnout operation function is active when the input type is thermocouple, resistance
temperature detector and standard signal.
It is not active for DC voltage and resistance inputs.
When the input type is standard signal, a burnout is judged at a voltage of 0.1 V or less.
Parameter Name Setting Range Default Explanation
Burnout detection OFF, UP, DOWN UP
This parameter is for setting burnout
detection.
7.1.6 Data Acquisition Interval
Analog inputs are sampled at a sampling period of 1 ms. However, the data acquisition
interval can be changed to one of 1 ms, 10 ms, 50 ms, or 100 ms. This setting is
common to all channels.

1 ms
Values input at the sampling interval of
1 ms can be acquired at a preset
interval and set as the measured
value.
7.1.7 Bias
The result of adding the bias setting value to the value after scaling is taken to be the
measured value.
Parameter Name Setting Range Default Explanation
Bias
The default follows
each input type in the
input type table.
±99999 range.
0
The decimal point position follows the
decimal point position set for scaling or
the measured value.
