Ω for input signal DC current
• Option: Heater burnout Alarm
(1) This alarm is not available for detecting current
under phase control.
(2) Use the current transformer (CT) provided, and pass a
lead wire of the heater circuit into a hole of the CT.
(3)When wiring, keep the CT wire away from any AC source
or load wires to avoid the external interference.
