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
ON: 1 kΩ max., OFF: 100 kΩ min.
ON residual voltage: 1.0 V min., OFF leakage current: 0.1 mA max.
Approx. 1.1 mA (per input)

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.
1% to 100% (Default: 100%)
Detects a burnout at or above the
specified output value.
0.0% to 100% (Default: 0.0%)
0 to 999 (Default: 150)
Burnout of 1 of 10 heater elements
can be detected (at the rated cur-
rent).
