Specifications Section 2-1
Current detection Current transformer
(CT) --- Built-in
Current detection
accuracy --- 10% FS of rated current
Minimum detected load
current --- 1 A
Heater burnout
alarm Burnout detection
accuracy --- 10% FS at rated current
(Not applicable to loads with variable
resistance.)
Detection method --- According to heater resistance (with
heater resistance teaching and
Heater Burnout Threshold parame-
ter)
Note The accuracy of heater burn-
out detection will be lower for
heaters for which the resis-
tance significantly changes
depending on the tempera-
ture.
Setting range for heater
burnout detection --- 1% to 100% (Default: 100%)
Burnout detection
output lower limit --- Detects a burnout at or above the
specified output value.
0.0% to 100% (Default: 0.0%)
Number of alarms for
heater burnout
detection --- 0 to 999 (Default: 150)
Multiple heater burnout
detections --- Burnout of 1 of 10 heater elements
can be detected (at the rated cur-
rent).
Event inputs Number of event inputs 2 event inputs
Event input 1: The function of the event input can be changed with a
parameter setting in the initial setting level. The event input
can be used for one of the following functions.
• Switching the main setting between automatic and man-
ual operation.
• Switching between phase control and optimum cycle
control.
Event input 2: Alarm reset
