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 specified. 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 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.

I01 and I02 on the /A1 option

I01, I02, I03, and I04 on the /A2 option

I01, I02, I03, I04, I05, and I06 on the /A3 option
