CH1 Simultaneous temperature rise status
The execution status of the simultaneous temperature rise can be monitored in this area.
• 0: Simultaneous temperature rise not in process
• 1: Simultaneous temperature rise in process
During control by the simultaneous temperature rise function, Simultaneous temperature rise in process (1) is stored in this
area.
The following figure shows the timing on when Simultaneous temperature rise not in process (0) is stored in this area. In the
figure, CH1 and CH2 have been set to Group 1. ( Page 302 CH1 Simultaneous temperature rise group setting)
CH1 Set value (SV)
CH2 Set value (SV)
'Setting/operation mode command' (Y1)
'CH1 Simultaneous temperature rise
status' (Un\G414)
and 'CH2 Simultaneous temperature rise
status' (Un\G614)
'CH1 Temperature rise judgment
flag' (Un\G404)
and 'CH2 Temperature rise judgment
flag' (Un\G604)
Completion of the temperature rise does not set 'CH1 Simultaneous temperature rise status' (Un\G414) to Simultaneous
temperature rise not in process (0).
As shown in the figure above, the simultaneous temperature rise function raises the temperature to a certain point, and
Simultaneous temperature rise in process (1) is set during the temperature rise. After the point, the temperature rises based
on the PID constants of CH1, and Simultaneous temperature rise not in process (0) is set.
