CT monitor method selection
Set the method for executing the heater current measurement.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory area name
CT monitor method selection
CT monitor method selection (in the Q compatible mode)
■Settable modules
• R60TCTRT2TT2BW
• R60TCRT4BW
■Setting range
• 0: ON/OFF current
• 1: ON current
When ON/OFF current (0) is set, the present current value of the current sensor (CT) is measured.
When ON current (1) is set, the current value of the heater being OFF is fixed as the current value of the heater previously
being ON.
■Default value
The default value is ON/OFF current (0).
CH1 Heater disconnection alert setting
Set the set value used for heater disconnection detections and output off-time current error detections in percentage (%) of
the reference heater current value.
For details on the heater disconnection detection function, refer to the following:

■Supported modules
• R60TCTRT2TT2BW
• R60TCRT4BW
■Setting range
The setting range is 0 to 100 (%).
An out of setting range error (error code: 1950H) occurs when the current value to be used as a judgment
value to detect heater disconnections (Reference heater current value  CH Heater disconnection alert
setting (%)) is smaller than 0.1A or 0.01A. For details on the setting, refer to the following:
