Chapter 5. SETTINGS BEFORE STARTING OPERATION
The following settings are necessary when using the CT (Current Transformer) input of the optional model.
For CT input, two kinds of current values are provided.
• Current value at output ON: This value is used for the heater burnout/over-current event. The value is displayed
as CT current value.
• Current value at output OFF: This value is used for the heater short- circuit event. The value cannot be displayed.
When [CT type] is set at “heater burnout detection”, the current value at output ON becomes the CT current value
measured when the output specified in [CT output] is turned ON. The current value at output OFF becomes the CT
current value measured when the output specified in [CT output] is turned OFF.
When [CT type] is set at “current value measurement”, the current value at output ON becomes the measured CT
current value regardless of output ON/OFF status. The current value at output OFF is fixed at “0.0A”.
