1. INTRODUCTION

Congratulations on your purchase of a Yamato Scientific's product. 'I his document discusses the operation of Model High-Tech IV Programmable Controller, especially the inputting and presetting methods of its various functions, whi ch are not described in the operating instructions of the systems equipped with the programmable controller. The programmable controller supports the operations and performances of Yamato Scientific's machinery and equipment, This means that some of the functions discussed in this document may not work on the system you have purchased. Please refer to the operating instructions of your system for the operations and performance which are supported by the programmable controller.

This Operating Instructions 1 is the basic user's guide of Model High-Tech IV Programmable Controller. Upon your request, Yamato Scientific will furnish you with Operating Instructions 2, which discusses detailed operating procedures and programming concepts of the programmable controller

Indication of Characters The control panel of Model High-Tech TV Programmable Controller uses 7-segment light emitting diode (LED) to show alphanumeric characters 04 its d splay. This 7segment LED naturally has its limitation in expressing individual characters. Please take note that the alphabetical characters of 'W." "m," t," "G," "r," "ｉ," "A,"V and k" are expressed by the substitutes below. Character Indication Character Indication Character Indication W G A

2. INPUTTING, EDITION AND DELETING PROGRAMS

2.1 Program Composition

A program is a combination of segments and repeat commands, in which ramp time, ramp level, repeat frequency, end segment and other parameters should be preset. [Segment] Fig 2.1 shows the concept of a segment. Temperature and time patterns of a segment are determined by the 3 basic parameters below. Ramp level : Desired temperature Ramp time : Time required to achieve the preset ramp level Soak time : Time to hold the ramp level

Fig. 2.1: Concept of A Segment

In Section (① of Fig. 2.1~ temperature varies at a fixed gradient rate toward the desired temperature set as the ramp level . After reaching the ramp level , temperature

is kept in Section② of Fig 2.1 for the time preset as the soak time. These sections of and② compose a segment.

If you want to vary the temperature in Section① on a step (for full-power increase or decrease), instead of a faced gradient rate, set for the ramp time. Fig. 2.2

shows the pattern of a step variation of the ramp time.

①

Fig. 2.2: Step Variation of Ramp Time The soak time is set at zero (0) for a s egment with only gradient-operation, wh ile the ramp time is set at zero (0) for a segment with only fixed -value operation. Figure 2.3 shows a connected pattern of these 2 segments. In this figure, Section (4) is a segment only with the soak time set at zero (0).

Attribute Parameters of Segments

■■■■

Attribute Parameters of Segments Attribute Parameters of Segments In addition to the three basic parameters discussed above, you may preset the following parameters.

Wait Function ON/OFF: This function temporarily suspends counting time of the program operation when influence of loads in the chamber or external disturbance such as door operation has the chamber temperature failed in achieving the preset desired temperature until the chamber temperature reaches the preset value. You may either turn ON or OFF the function.

Fan Revolution

Fan Revolution: You may preset the revolution of the internal agitation fan in the

Fan RevolutionFan Revolution range from 1 (low speed) to 10 (high speed). See the operating instructions of your system for the fan revolution (rpm), which varies with systems. If your system cannot control the fan revolution, the programmable controller automatically skips this functi on. If your system is equipped with optional automatic damper controller, you may preset the damper aperture at 5 different levels.

End Segment

End Segment :When you want to complete programming, input "End" in the ramp

End SegmentEnd Segment time, which creates the end segment. You may preset the fan controller at ON/OFF or one of its 10 levels as a parameter of the end segment.

Note: Model High-Tech IV Programmable Controller allows you to compose a program

NoteNote of maximum 16 segments, which can be divided to make several different programs.

[Repeat Command]

[Repeat Command][Repeat Command] Repeat Command allows you to repeat a series of segments as many time as yon wan t. This command is composed of 2 parameters; Repeat Start Segment and Repeat Frequency.

Repeat Start Segment: Program repeats the section between the segment designated as the repeat start segment and the segment immediately before the repeat start segment.

Note

Note: (1) Repeat Command works for only the segments that were input and preset

NoteNote

before the command. In other words, you cannot repeat the segmen4 which you preset after the repeat command.

appears next to a time setting of (999

(2) You cannot preset the nesting of a repeat command, which means to insert a

repeat command into the existing repeat command , as sh own in F ig. 2.4.1. It is also impossible, as shown in Fig. 2.4.2, to preset a repeat command across the existing repeat command.

Fig.2.4.1:Nesting of a Repeat Command

Fig.2.4.2:Cross Setting of Repeat Commands

Repeat frequency

Repeat frequency :You may preset Repeat Frequency in the range from 1 to 9999

Repeat frequencyRepeat frequency times. If you set the repeat frequenc y at zero(0),wh i ch means endless repetition of th e segments ,the program continues repeat operation until it is fo rced t o st op.
