Manual Output
7-8
Allows the control output to be manually set at an arbitrary value.
●
Manual Mode Display
A decimal point will light up at the bottom right of the display during manual mode.
The same decimal point appears on the parameter setting display.
●
Switchover between Auto and Manual
Modes can be changed by four methods: the front key (user key), DI function, communica-
tion function, or the parameter "

Ramp Soak Function
Automatically runs after setting the times for the SV changes.
You can choose up to sixteen steps for the SV setting and seven types of ramp soak operation
patterns.

Creating a ramp soak operation pattern
Set the following items to create a pattern.
Pattern
Sets which steps to use from the following seven types.
Steps 1 to 4 / Steps 5 to 8 / Steps 9 to 12 / Steps 13 to 16 / Steps 1 to 8 / Steps 9
to 16 / Steps 1 to 16
Target SV
Sets the controlled temperature.
Ramp time
Sets the time to reach the target SV from the current SV.
Soak time
Sets the time to maintain the specified SV.
The following steps will explain how to run the specified pattern 0 in SV-1 to SV-4.

This function guarantees the soak time. Only soak time within the specified range of tempera-
ture for SV is counted towards soak time.
As seen in the figure below, only the sum of the shaded areas is counted as soak time. The
operation moves onto the next step when the total soak time equals the specified soak time.
The following steps will explain how to set an example guaranty soak range with an upper limit
of 5°C and a lower limit of 3°C.
