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.

Select one among 6 alarm operations [AL-1

/2/3/4/5/6] of event 1, 2[EU-1, EU-2] at parameter 2 group and set alarm

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 or SBA function in EU-1

, EU-2 of parameter 2 group, alarm cannot be operated.

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 first 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 first alarm condition is ignored and from the second alarm condition,

alarm latch operates.
