Alarm output is triggered if the control subject's temperature exceeds or falls below
the preset temperature range.
Alarm temperature setting values are available both with absolute temperature and
deviation temperature depending on the alarm output mode.


Deviation High-limit Alarm

(Temperature, Analog: +F.S.)
If PV/SV deviation occurs higher than set
value of deviation temperature, alarm
output will be ON.
High-limit deviation temperature can be
set in AL1.H/AL2.H.
Deviation Low-limit Alarm

OFF
(Temperature, Analog: +F.S.)
If PV/SV deviation occurs lower than set
value of deviation temperature, alarm
output will be ON.
Low limit can be set in AL1.L/AL2.L.
Deviation high/low limit alarm

(Temperature, Analog: +F.S.)
If PV/SV deviation occurs higher than
high-limit deviation or lower than low-limit
deviation, alarm output will be ON.High-
limit Deviation Temperature can be set in
AL1.H/AL2.H.
Low limit can be set in AL1.L/AL2.L.
Deviation High and lower limit

Reverse Alarm (Temperature, Analog:
0)
If PV/SV deviation occurs higher than
low-limit deviation or lower than high-limit
deviation, alarm output will be ON.
High-limit deviation can be set in
AL1.H/AL2.H.
Low limit deviation can be set in
AL1.L/AL2.L.
