■When the input range automatic change setting has been set to Enable (1) ('Automatic setting
at input range change' (in the Q compatible mode) (Un\G1024, b0) in the Q compatible mode)
When the input range is changed, the following buffer memory areas are set automatically depending on a selected
temperature sensor. Set the buffer memory areas again if necessary.
• 'CH1 Upper limit setting limiter' (Un\G511)
• 'CH1 Lower limit setting limiter' (Un\G512)
• 'CH1 Set value (SV) setting' (Un\G430)
• 'CH1 Proportional band (P) setting' (Un\G431) (only R mode)
• 'CH1 Heating proportional band (Ph) setting' (Un\G431) (only R mode)
• 'CH1 Alert set value 1' (Un\G434)
• 'CH1 Alert set value 2' (Un\G435)
• 'CH1 Alert set value 3' (Un\G436)
• 'CH1 Alert set value 4' (Un\G437)
• 'CH1 Cooling proportional band (Pc) setting' (Un\G439) (only R mode)
• 'CH1 Setting variation rate limiter/setting variation rate limiter (temperature rise)' (Un\G513) (only R mode)
• 'CH1 Setting variation rate limiter (temperature drop)' (Un\G514) (only R mode)
• 'CH1 Adjustment sensitivity (dead band) setting' (Un\G516) (only R mode)
• 'CH1 Overlap/dead band setting' (Un\G524) (only R mode)
• 'CH1 Alert dead band setting' (Un\G531) (only R mode)
• 'CH1 Loop disconnection detection dead band' (Un\G538)
• 'CH1 AT bias' (Un\G546)
• 'CH1 Simultaneous temperature rise gradient data' (Un\G554)
• 'CH1 Simultaneous temperature rise dead time' (Un\G555)
• 'CH1 Disturbance judgment position' (Un\G557)
• 'CH1 Sensor correction value setting' (Un\G565) (only R mode)
• 'CH1 Sensor two-point correction offset value (measured value)' (Un\G568)
• 'CH1 Sensor two-point correction offset value (corrected value)' (Un\G569)
• 'CH1 Sensor two-point correction gain value (measured value)' (Un\G570)
• 'CH1 Sensor two-point correction gain value (corrected value)' (Un\G571)
■When the input range automatic change setting has been set to Disable (0) ('Automatic setting
at input range change' (in the Q compatible mode) (Un\G1024, b0) in the Q compatible mode)
A value set in a buffer memory area may be out of the setting range. (Because changing the input range changes the setting
range and the set value before the change may become out of the setting range after the change.) In this case, an out of
setting range error (error code: 1950H) occurs in the buffer memory area where the set value is out of the setting range.
Change the input range after setting a value within the setting range after the input range change in each buffer memory area.
■Enabling the settings
Turn ON and OFF 'Setting change command' (YB) in the setting mode ('Setting/operation mode status' (X1): OFF) to enable
the settings.
■Precautions
Soon after the input range is changed, the input temperature may be unstable. Do not start the control until 'Temperature
conversion completion flag' (Un\G43) becomes First temperature conversion completed (1H).
■Default value
• For the R60TCTRT2TT2 and the R60TCTRT2TT2BW, the default value is 2.
• For the R60TCRT4 and the R60TCRT4BW, the default value is 7.
