Note 2) When using the heater break alarm, set the parameter “TC” to 20 or more.
Set the CT (current transformer) so that it measures the current of the heater connected
to the control output 1.
Disconnection of the control output 2 cannot be detected.
Never set “TC” / “TC2” = 0.
· Some parameters may not be displayed on the screen, depending upon the types.
