* When the event type is CT1/2 heater burnout/over-current or CT1/2 heater short-circuit, the status becomes that the
event judgment cannot be made from the time of power ON until that CT input current value is measured for the first
time. In this case, the internal event output is OFF for both of direct action and reverse action in the direct/reverse setting.
To avoid that the output becomes OFF at power ON when used in reverse action, set as follows:
(Setting example)
For direct/reverse setting of CT1/2 heater burnout/over-current or CT1/2 short-circuit event, select the direct action, and
set the reverse operation in DO assignment calculation of the event output terminal (event terminal or control output
terminal).
