Heater Burnout Alarm
Max. heater current
Single-phase 50 A VAC (see note 1)
Heater current value display accuracy
±
5% FS
±
1 digit max.
Heater burnout alarm setting range
0.1 to 49.9 A (in units of 0.1 A) (see note 2)
Min. detection ON time
190 ms (see note 3)
Note:
1. Use the K2CU-F
jj
A-
j
GS (with gate input terminals) for the detection of three-phase heater burnout.
2. The heater burnout alarm is always OFF if the alarm is set to 0.0 A and always ON if the alarm is set to 50.0 A.
3. No heater burnout detection or heater current value measurement is possible if the control output (heat) is ON for less than 190 ms.
