How to Compose a Program Program Composition One program is composed of segments and a repeat command. Each segment comprises ramp time, ramp level, soak time, and end segment. On the other hand, a repeat command comprises repeat start segment and repeat frequency. Contents of a Segment Components of a Segment • A program is composed of segments, and the pattern of each segment is set by the following 3 elements. 1. Ramp level : Desired set temperature 2.
Contents of a Segment • Not in Ramp Operation (See Figure 2). 1. When you want to achieve the ramp level in a ramp block as soon as possible, set the ramp time at Measured Temperature(°C) Soak Block(c) Ramp Level Time Soak Time Setting the ramp time at (Fig. 2: Schematic of a Segment Not in Ramp Operation) • Combining Ramp Operation (See Figure 3.) 1.
Contents of a Segment • Other Elements relating to Segment 1. Wait Function (See the following example for setting the wait function). If unexpected additional load or disturbance prevents measured temperatures from reaching the desired temperature, this function keeps the operation in a block until the desired temperature is achieved. After inputting the soak time, set ON or OFF. 2. End Segment At the end of inputting a new program, set in the ramp time of the last segment.
Contents of a Segment Contents of a Repeat Command • Composition of a Repeat Command With the repeat command, you can repeat a series of segments as many times as you like. composed of repeat start segment and repeat frequency. This command is 1. Repeat Start Segment In the segment input mode, input the segment number from which you want to repeat the cycle. The controller repeats the cycle from your desired start segment to the segment immediately before the repeat start segment.
Inputting a Program This paragraph discusses how to input a program. See Figure 4. Measured Temperature（°C） Repeat Command (Repeat Segment 2 and 3 three times) 1 hour 30 min Segment 1 Segment 2 1 hour 30 minutes 1 hour 30 minutes STEP Segment 4 Segment 3 End Segment 1 hour Wait function On 0 1 2 3 Wait function On 4 5 6 7 8 9 10 11 12 Time Fig. 4 : Inputting a Program Indication after Step/Step Procedure Explanation Setting a Program Number 1.

Editing a Program With the program edit function, you can edit the registered ramp time, ramp level, soak time, wait function, repeat start segment and the number of repeat cycles on the segment basis. CAUTION : You cannot delete the registered segments or the repeat command and insert new segments or a repeat command. Based on Figure 4 of “Inputting a Program,” this paragraph discusses how to edit Segment 3 from the step operation to the constant ratio ramp operation.
