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
-
1 program pattern using 30 steps maximum can be created.
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.

PAt3
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 27and 28 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 10
℃
within 1 minute, about 10 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 26 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 DR200
The temperature fall curve and temperature rise curve for DR200 are shown below.
The numeric value indicates the necessary time between temperatures (ex: about 9 minutes is
needed to increase temperature from 400
℃
to 500
℃
). 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.
