Operation Method
Program Operation
This operation is used to change the temperature according to the setting temperature and time.
Program types
Six patterns of program types maximum can be input.
PrG1
-
At factory shipment, the unit is set to perform one-hour sterilizing
operation program at the temperature of 180
℃
. One program
pattern using 30 steps maximum can be created if the operation
above is deleted.
PrG2
PAt1
2 program patterns using 15 steps maximum can be created.
PAt2
PrG3
PAt1
3 program patterns using 10 steps maximum can be created.

Before inputting program
…
Input program patterns before program operation.
①
Check the number of steps in a created program and their setting temperature/time. Use the
program preparation sheet in pages 29and 30 to check.
②
Check the temperature rise/fall capability of the unit. Set the time within the capability above.
Suppose, for instance, that in the unit which has capability of increasing or decreasing
temperature by 50
℃
within 15 minutes, about 30 minutes is needed to increase or decrease
temperature by 100
℃
from current temperature
Repeat function:
Repeat function is useful in case the operation uses the program repeating the same program
steps. Refer to page 28 for the function.
③
Check if the controller has sufficient free pattern for the number of steps to be created. The steps,
however, using the repeat function mentioned above are not counted.
Temperature fall/rise curve for SH type
The temperature fall curve and temperature rise curve for SH type are shown below.
The numeric value indicates the necessary time between temperatures (ex: about 15 minutes is
needed to increase temperature from 100
℃
to 150
℃
). Temperature stability time after reaching
to the setting temperature is necessary to be added. Make sure to conduct a test run before
setting the optimum time.
Condition: room temperature 25
