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).

Fig. 2.3: Connection of Segmen4

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.

(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.

3.6 Hold Function

3.6 Hold Function3.6 Hold Function

Hold function is the one of functions that the HitecⅣcontroller supports by using the MODE key. It can work only if the setting time of the operation start time of the Auto-Start operation and the Program operation and the operation stop time are not set in hours but in a period of time.

General Description of the Hold Function

General Description of the Hold FunctionGeneral Description of the Hold Function

Once the Hold Function is on, i mmediately the HitecⅣcontroller stops the built-in timer and keeps the condition. The definite examples are shown below.

1. When the Hold Function activated while the unit is in standby condition of starting operation, the waiting time to start is extended by a period of time when the Hold Function was on

2. When the Hold Function activated while performing the fixed gradient rate operation toward the desired temperature, the controller stops the gradient operation and changes to the fixed temperature operation to keep the internal target temperature of the controller at the point of time. ( The internal target temperature is not always same as the ramp level in the program segment) Once the Hold Function is off, the controller resumes performing the gradient operation that had been performed just before the Hold Function was on.

3. When the Hold Function activated while performing the gradient operation with full power , the controll er changes to the fi xed temperature operat ion to keep the chamb er at the ramp level in the program segment after reaching the ramp level (the desired temperature)

4. When the Hold Func tion activated while keepin g the chamber at the ramp lev el, the setting soak time in the Auto-Stop operation and the Program operation are extended by a period of time when the Hold Function was on

5. When you change a certain ongoing operation to the other operation by pushing the MENU key with the Hold Function is on, the Hold Function is automatically released at the point of time when the operation is changed.

4. SAFETY MEASURES AND PRECAUTIONS

This section discusses the safety measures provided for Model High-Tech IV Programmable Controller, and the operational precautions of the controller and your system regulated by the controller. See the operating instructions of your system, which also describe safety measures and precautions.

4.1 POST Function

POST stands for Power On Self Test, which is a special function to check the controller's microprocessor, memory, peripheral LSI's and peripheral circuits whenever you turn on Power key. With this POST function, you can make sure that the controller is free of serious troubles before starting operation. If the function defects something abnormal, the sub display shows one of error codes corresponded to the trouble from among error codes of

. These error codes mainly indicates a trouble of electronic circuits If this is the case, turn off the breaker and co ntact th e d eal er of your s ystem, Yama to Sci enti fic C D., L td. or Yamato Engineering Co., Ltd. in your vicinity.

4.2 Precautions

1) To prevent overheating, Model High-Tech IV Programmable Controller is equipped with automatic attempering function In ad dition, some of our systems also have their own attemperators in the circuit separated from the programmable controller. However, when you are working on exothermic samples or supplying electricity to samples to generate heat, those temperature regulating systems do not work effectively.

When temperature goes up abnormally high, shut down power supply or take any other appropriate measures Yamato Scientific is prep ared to modify your system to manage such troubles.

2) In case of power failure, the programmable controller of the standard specifications automatically resets itself and restarts operation when electric power becomes available again. If you install the optional Restart Selector Function In the controller, you can select either Automatic Reset or Manual Reset to restart operation after power failure for a certain period of time.

5. Behavior after Power Restoration

When having a blackout during operation, the controller resumes the following operations after the power restoration.
