4mA
PV
ST1
ST1+DF1
set AOM to ReV (Dehumidification
(Cooling) proportional Control)
ST1
Input SV at 4mA output.
DF1
Input DF at 20mA output.
* SV : ST1~ ST2
Deviation High Limit Alarm
Output is ON when the deviation between PV value and SV value is higher
than setup value of control deviation
OFF
Deviation Low Limit Alarm
Output is ON when the deviation between PV value and SV value is lower
than setup value of control deviation.
Deviation High & Low Limit Alarm
Output is ON when the deviation between PV value and SV value is higher
or lower than setup value of control deviation .
Control deviation is set up at DF in setting 1 group.
If DF value ≤ 0, it is always OFF.
Deviation High & Low Limit Reverse Alarm
Output is OFF when the deviation between PV value and SV value is higher
or lower than setup value of control deviation .
Control deviation is set up at DF in setting 1 group.
If DF value ≤ 0, it is always OFF.
ON
Absolute Value High Limit Alarm
Output is ON when PV value is higher than or equal as control deviation
setup value. Alarm temperature is set up at DF in setting 1 group.
It works regardless of SV(Set value).
HY
OFF
Absolute Value Low Limit Alarm
Output is ON when PV value is lower than or equal as control deviation
setup value. Alarm temperature is set up at DF in setting 1 group.
It works regardless of SV(set value).
Sensor Open Wire Alarm
DESCRIPTION FOR ALARM OPTION OPERATION
Standard alarm operation without option
Maintain output ON after alarm occurs
No output at initial operation (until achieve the 1st setup value)
Execute both ALB & ALC at the same time
