Alarm Outputs
Section 3-9
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 the upper-and lower-limit alarms in cases 1 and 2 above, the alarm
is always OFF if upper- and lower-limit hysteresis overlaps.
• In case 3, the alarm is always OFF.
(5) Set value: 5 (Upper- and lower-limit with standby sequence)
• The alarm is always OFF if upper- and lower-limit hysteresis overlaps.
• Set the alarm type independently for each alarm in the “alarm 1 to 3 type”
parameters in the initial setting level. The default is 2 (Upper-limit alarm).
