time
Note: 1. Use the K2CU-F@@A-@GS (with GATE input terminal) for
burnout detection of 3-phase heaters.
2. If the heater burnout alarm setting is set to 0.0 A, the alarm
is always OFF, and if it is set to 50.0 A the alarm is always
ON.
3. If the ON time for control output is less than 190 ms, heater
burnout detection and heater current measurement will not
be performed.
