Set the event function 3 (CT abnormality).
Event function 3 is a function to detect the current flowing in the heater that is assigned in the outputs 1 to 7 as target
connections, using the current transformer (CT) that is supplied as an accessory, and to compare the detected current to the CT
abnormality current.
This function is useful for detecting disconnected wiring to the heater or adhesion of a relay contact that turns on and off the
electricity to the heater.
For the details regarding the connection and setting of CT (current transformer), please refer
to Operation Manual CT (P5-40 to 44).
