Recovery with programmable recovery gradient
9.4.2
To enable cycle recovery with a recovery gradient, enter on parameter 22
  
a value (degrees/hour if temperature) greater than 1. At restarting if
the kiln temperature (process) is lower than the setpoint, ATR902 locks the
working cycle executing a step with the rising gradient set on parameter 22
  
to return to the setpoint value entered before the power failure and
the cycle restarts form that point. In recovery mode the point on the right of
the red display fl ashes and display shows
Recovery will start only for holding or rising steps.

This function has been conceived to control kilns working cycles, whenever
the kiln cannot follow gradients programmed by the user. If at step end the
diff erence between process and setpoint values is greater than the value on
