) cycle will resume from the point of interruption;
if the gap is bigger but controller has not yet executed a cooling step, the
cycle will go back to the closest rising step and will repeat the procedure
as explained on point 1.
3. If a power failure occurs during a cooling step or a holding step (dwell)
after that a cooling step has already been completed, the setpoint will
match the the temperature read by the sensor, without including any ri-
sing and even skipping to next step if necessary (this a safety tip particu-
larly for glass working).

Recovery with recovery gradient
To enable cycle recovery with a recovery gradient, enter on parameter 38
r.i.cY.
a value (degrees/hour if temperature) greater than 1. At restarting if
the kiln temperature (process) is lower than the setpoint, ATR421 locks the
working cycle executing a step with the rising gradient set on parameter 38
r.i.cY.
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
