Alarm Value
• Hgh Lmt Alarm/Low Lmt Alarm and Delay Hgh Lmt Alarm/Delay
Low Lmt Alarm
The following values can be specified.
• For DC voltage, TC, and RTD input: Values within the measurable range in the
specified 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.
• Dfference Hgh Lmt Alarm/Dfference Low Lmt Alarm
Values in the measurable range can be specified. Measurable range refers to
“Selectable Span Range” in the table on page 5-4.
• Hgh Lmt on Rate-of-Change Alarm/Low Lmt on Rate-of-Change Alarm
A value greater than or equal to 1 digit can be specified. 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 specified is the width of the measurable range (4.000 V
for 2 V range).
For ON/OFF input, only “1” can be specified.
Relay No.
The selectable relay numbers are listed below.
