Alarm Value
• High Limit Alarm/Low Limit Alarm and Delay High Limit Alarm/Delay
Low Limit Alarm
The following values can be specied.
• For DC voltage, TC, and RTD input: Values within the measurable range in the
specied range (example: –2.000 to 2.000 V for the 2 V range).
• For ON/OFF input (DI): 0 or 1.
• For linear scaling (1-5V
, scaling, and square root): A value within –5 to 105% of
the scaling span (version 1.11 or later) except within the range of –20000 to 30000
(excluding the decimal point).
Note
For channels whose the leftmost value of the scale is set to –20000 (excluding the decimal),
the alarm value of –20000 is invalid. Set a value that is greater than or equal –19999.
• Difference High Limit Alarm/Difference Low Limit Alarm
Values in the measurable range can be specied. Measurable range refers to
“Selectable Span Range” in the table on page 5-4.
• High Limit on Rate-of-Change Alarm/Low Limit on Rate-of-Change Alarm
A value greater than or equal to 1 digit can be specied. For example, 1 digit
corresponds 0.001 for the 2 V range (measurable range: –2.000 to 2.000 V). The
maximum value that can be specied is the width of the measurable range (4.000 V
for 2 V range).
For ON/OFF input, only “1” can be specied.
Relay No.
