(d) When the simultaneous temperature rise parameter cannot be calculated
The simultaneous temperature rise parameter cannot be calculated under the following conditions:
• When the maximum gradient is not determined
• When the saturation time for output is short
The temperature control module turns CH AT simultaneous temperature rise parameter calculation error
status (b1, b5, b9, b13 of RWr3) to 1 (ON).
