•
Set the alarm mode selector 1 to 0 (i.e., no alarm function is ON)
so that alarm output 1 will output only heater burnout alarms.
•
If the difference in current is small, increase the apparent
electrical current by increasing the number of turns of the heater
wire around the CT. The current displayed by the heater current
value display increases in proportion to the number of turns of
the heater wire.
•
Use the K2CU-F

GS (incorporating gate input terminals)
for detecting three-phase heater burnout.
Output Retention Reset
Once the heater burnout alarm detects heater burnout, alarm output
1 will turn ON. To turn OFF alarm output 1, set the heater burnout
alarm value to 0.0 A or turn off the Temperature Controller and then
turn on the Temperature Controller.
