3.4 Buffer Memory Assignment
3.4.2 Details of the buffer memory
(38)Alert dead band setting (Un\G164)
This setting is for using the alarm function.
For details on the alert function, refer to the following.
Page 194, Section 4.12
(a) Setting range
Set the value within the range 0 to 100 (0.0% to 10.0%) of the full scale of the set input range. ( Page 96,
Section 3.4.2 (12))
Ex.
When the value of the buffer memory is set as follows
•CH Input range (Un\G32, Un\G64, Un\G96, Un\G128): 2 (temperature measurement range 0 to 1300°C)
• Alert dead band setting (Un\G164): 5 (0.5%)
(Full scale) × (Alert dead band) = (1300°C - 0°C) × 0.005 = 6.5°C
The dead band is the alert set value (SV) ±6.5°C.
(b) Default value
The default value is set to 5 (0.5%).
(39)Number of alert delay (Un\G165)
Set the number of sampling for an alert judgment.
By setting number of sampling, when the temperature process value (PV) stays within the alert area until the
number of sampling exceeds the number of alert delay, the alert status will be active.
For details on the alert function, refer to the following.
Page 194, Section 4.12
(a) Setting range
The setting range is 0 to 255 (times).
(b) Default value
The default value is set to 0 (times).
Under 0 (times) condition, if the temperature process value (PV) enters the alert area, the alert status becomes
active instantly.
