31.1 Recovery of interrupted cycle with automatic gradient
Temperature
T i m e
To desable this function,
enter 0 (zero) on parameter 23
.
Recovery function is particularly useful
for temperature control on kilns. At
restarting after a power failure ATR620
can resume the interrupted cycle,
assuring optimal cycle execution.
4. Power failure during a rising step:
recovery gradient will be the same
as the step in progress. Setpoint
value will be the same as sensor
temperature.
5. Power failure during a dwell
(holding step): two options are
available. If the gap process-
setpoint is not bigger than value
entered on P-22, cycle will be
resumed from the point of
interrumption. If the gap is bigger
than this value, cycle will be
resumed from previous step and
will follow point1.
6. Power failure during cooling steps:
setpoint follows the temperature of
sensor and controller will not
foresee any rising step (safety
feature for glass kilns) , skipping to
next step if required.

After a power failure chronometer
always starts from 00:00
