can be set independently for each alarm type, and are

expressed as “L” and “H.”

2. Set value: 1, Upper- and lower-limit alarm

3. Set value: 4, Upper- and lower-limit range

4. Set value: 5, Upper- and lower-limit with standby sequence

For Upper- and Lower-Limit Alarm Described Above

• Case 1 and 2

Always OFF when the upper-limit and lower-limit

hysteresis overlaps.

• Case 3: Always OFF

5. Set value: 5, Upper- and lower-limit with standby sequence

Always OFF when the upper-limit and lower-limit hysteresis

overlaps.

6. Set value: 12, LBA (loop break alarm) can be set only for
