Alarm Types
Select alarm types out of the 12 alarm types listed in the following table.
Note: 1. With set values 1, 4 and 5, the upper and lower limit values
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. The annunciator output turns ON to inform users when a
limit over occurs. This function is enabled by selecting 12
(annunciator output) for alarm 1 type. The annunciator
output turns ON when a limit over occurs, and turns OFF for
the RESET operation.
Set the alarm types for alarms 1 and 2 independently in the initial
setting level. The default setting is 12 (annunciator) for alarm 1 type
and 2 (upper limit) for alarm 2 type.
