Dual PID Auto Tuning Control
This unit has output for control and sub(alarm) output. Sub output is optional. (This alarm output is relay contact(1a) and
operates regardless of output for control.) Alarm output operates when the temperature of target is getting higher or lower
than setting value.

of event 1, 2[
EU-1

temperature (deviation or absolute temperature) in AL1, AL2 alarm temperature[
AL1
,
AL2
] at parameter 1 group.
● Since
EU-1
and
EU-2
operate separately, both
EU-1
and
EU-2
can be used as a high or low 2nd alarm operation.
● When selecting
LBA

function in
EU-1

Mode Name Description
AL-A
Standard alarm If it is an alarm condition, alarm output is ON. If it is a clear alarm condition, alarm output is OFF.
AL-B
Alarm latch If it is an alarm condition, alarm output is ON and maintains ON status.
AL-C
Standby sequence
First alarm condition is ignored and from second alarm condition, standard alarm operates.
When power is supplied and it is an alarm condition, this rst alarm condition is ignored and from the
second alarm condition, standard alarm operates.
AL-D
Alarm latch and
standby sequence
If it is an alarm condition, it operates both alarm latch and standby sequence. When power is supplied
and it is an alarm condition, this rst alarm condition is ignored and from the second alarm condition,
alarm latch operates.
