3.1.2 Operating Principles

Structure and Principle of Thermo-module

A thermo-module (Thermoelectric device) is a unit consisting of multiple semiconductor elements. Itcan perform cooling and heating freely with direct current, be placed in line for electric purposes and be placed in parallel for thermal purposes. When two different conductors or semiconductors are connected and direct current is applied to them, suction or the generation of heat other than Joule heat is seen at the connected part; this is called the Peltier effect. If P-type and N-type semiconductors are connected with a metal, as shown in the figure below, and current is applied, the suction of heat is seen at the connected part. The other connected part will have a high temperature and will generate heat. This effect is reversible; suction and the generation of heat occurs in the opposite direction when the current direction is reversed. Therefore, if the heat at the high temperature side is handled efficiently, a continuous heat pumping from low temperature side to high temperature side can be realized. With this principle, the N-type semiconductor has an electron current flowing in the opposite direction to the current and the P- type semiconductor has a hole current flowing in the same direction as the current. These electron and hole current move heat.

Operation Principle

In this product, many thermo-modules are placed in line between heat exchangers. At one side, cooling water is supplied and at the other side, a tank storing the recirculating fluid is mounted. Both ends of the thermo- modules that are connected electrically in line have a DC power supply whose current is regulated by a Controller. A temperature sensor placed at the inside of the liquid tank (platinum resistive temperature detecting sensor) sends a signal to the Controller and the Controller adjusts the direction and time of the built-in DC power supply output depending on the deviation of the signal from the set temperature, which results in precise control of the recirculating fluid temperature.

3.2 Function 3.2.1 Auto Tuning Function

This function automatically adjusts the PID values (proportional band, integrating time, and derivative time) necessary for control. To learn how to operate this function, refer to page 5-10, 5.4.7 Details of Initial Setting Mode.

[Tips]

Appropriate PID values are input at the time of shipment from the factory. If

the temperature deviation is found at these values on a regular basis, try to

perform auto tuning. The Controller will calculate and set PID values

automatically. Auto tuning may require a significant amount of time to

complete, depending on the operating conditions.

If auto tuning fails, return to the values set at the time of shipment from the

factory (refer to page 5-12, 5.4.9 Details of Control Setting Mode) or input

the optimum values.

3.2.2 Temperature Upper / Lower Deviation Limit Alarm Function (at shipment)

This function generates an alarm when the measured temperature deviates from the set temperature by an amount outside of that defined as the upper or lower limit deviation. In that case, the AL1 LED of the Controller lights up and the alarm is generated via relay contact to a pin for the temperature upper/lower deviation alarm of the alarm output connector. After the measured temperature returns to within the upper or lower deviation, the alarm will be reset automatically. In its initial setting, the alarm comes on immediately after the power supply is turned on when the temperature at that time deviates from the set temperature by an amount outside of the upper or lower deviation limit. It is possible to change this setting so that the alarm will not come on during warm-up to a temperature within the upper and lower deviation limit after the power supply is turned on.

3.2.3 Offset Function

This function adjusts the measurement range of the temperature sensor from -1.0 to 1.0

o C. The temperature sensor can be calibrated by inputting

the difference (calibration value) between the temperatures of a standard thermometer and the temperature sensor.

[Tips]

The Controller has already been given the calibration value of 25

independently. This input value is described in the Inspection Record.

3.2.4 Set Value MemoryEEPROM back-up

This function memorizes all set values input via the operation and display panel to nonvolatile memory EEPROM as back-up. Even if the power supply is turned off, the settings remain and do not need to be reset when the power supply is restarted.

3.2.5 Output cutoff Alarm Function

This function cuts off output to the thermo-module (stops control) and generates an alarm when a serious abnormality occurs. When the alarm occurs, the TROUBLE LED lights up and the alarm is generated via relay contact to the pin for the output cutoff alarm of the alarm output connector. The specifications of the relay contact are shown in Table 3-3. This alarm cannot be reset unless the power supply is turned off once and restarted. Problems that may cause this alarm include the following:

Overheating of Liquid Tank (Thermostat starts operating.)

Lowering of Controller output voltage

Stopping of Controller fun rotation

The writing limit is approx. 0.1 million times. If the setting is performed via the communication function, pay

attention to how many times the writing has been done.

Any set value input via the communication function is not stored. If they need to be stored, use a storage request message.

4.2.1 Preparation of Cooling Water

Connect fittings to the ports (Rc1/4) marked IN and OUT on the Liquid Tank to provide piping for the inlet and outlet of cooling water, respectively.

When connecting fittings to the ports, prevent leakage with seal tape or other methods. Also, hold the fitting mounting part with a spanner to avoid applying directly to the fitting mounting part of the product the force created by connecting the fittings. The recommended tightening torque is 12 to 14Nm.

The appropriate flow rate range is from 3 to 5L/min. If a higher flow rate is supplied, the cooling and heating capacity will be slightly affected, but a flow rate of lower than 3L/min will impair the cooling and heating capacity significantly.

Be sure to avoid operating the product without cooling water or with cooling water at extremely low flow rates. At low flow rates, the cooling water temperature can reach approx. 90oC and soften and rupture resin tubes, which can be used for connection. Therefore, naturally cool down the product and supply the cooling

water at an adequate rate.

Supply the cooling water at 8L/min or less in order to prevent the

radiating system from being damaged.

Use fresh water such as tap water for the cooling water. If cooling water is circulated, control the quality of the cooling water to prevent corrosion of the wetted material. For quality standards for the cooling water, refer to page 4-5, 4.2.2.Quality of Cooling Water

[Wetted material] SUS303, SUS304, FEPA6063(anodized)

4.2 Piping

4-4

Keep the cooling water temperature between 10 and 35. (No dew

condensation) Note that the cooling and heating capacity is changed depending on temperature. Also, when low-temperature cooling water is supplied, dew condensation may occur, damaging the internal electric equipment. Keep the temperature above the atmospheric pressure dew point. Alternatively, the user may take measures to prevent dew condensation, such as an N2 purge. To obtain the dew point, refer to page 7-22 7.6 Calculation of Dew Point Temperature

(from psychrometric chart).

The maximum operating pressure is 0.5MPa. Keep the pressure as

low as possible to prevent water hammer.

Eliminate all conditions which could cause the cooling water or

fluid leakage.

4.2.3 Preparation of Recirculating Fluid

Supply recirculating fluid slowly by using a funnel or a manual pump.

The recirculating fluid has effective range of levels. Check that it reaches that range under operating conditions.

Confirm that the recirculating fluid reaches the level marked LOW at the inner face of the liquid tank. HIGH is not marked but consider to be at the upper end of the outside tank. Keep within this range. (Refer to page 7-1, Fig. 7-2 Internal dimensions of Liquid Tank.)

Check the fluid level at least once a day. The recirculating fluid may evaporate. The product is unable to maintain performance at a significantly lower fluid level and this could cause breakage of the circulating pump. Maintain the

appropriate level at all times.

Check at least once a day for the presence of foreign matter in the recirculating fluid. If foreign matter enters the circulating pump, the pump could

break.

Use fresh water (tap water) that satisfies the quality standards shown in Table 4-1 for cooling water. If other liquids are used, the product could break and leak fluid, resulting in electrical shock or earth leakage.

Do not operate without recirculating fluid, or the product may idle

and break.

Do not use in such a manner that the recirculating fluid overflows or splashes during operation. This could cause the machine to

break.

If water is used for the recirculating fluid, keep the temperature at 5oC or more (considering the offset value). Use at a lower

temperature could break the circulating pump.

When the set temperature is increased from a low value to an ordinary value, some kinds of the recirculating fluid can swell, increase and overflow, which can not only break the thermo electric bath and other equipment, but also cause a serious accident. Take a measure to prevent this situation in advance by decreasing the amount of the recirculating fluid, etc.

4.2.4 Draining the Recirculating Fluid

Stop the product (cut the power supply and cooling water) and remove the connected cables and piping before draining.

This product does not contain a draining function and the recirculating fluid thus needs to be drained with a manual pump.

Draining from the bottom of the tank or inside of the recirculating pump, which cannot be handled with a manual pump, can be performed by turning the tank so that the slits inside the tank are facing down and inclining the tank gradually.

Never perform operation under conditions that may create cavitation and lower the fluid level, which could allow the air to enter the fluid and break the pump.

To avoid the danger of electrical shock, do not perfom wiring

repairs or operate the product with wet hands.

Slit

Inclination of the tank for draining must be performed by two or more workers to prevent possible injury and/or damage to the product due to the tank being dropped. Also, because the recirculating fluid may spill from the tank, prepare a pan to receive it or work in a location where fluid spills can drain. Additionally, wear protective equipment Tipping of the tank for draining must be performed by two or more workers to prevent possible injury and/or damage to the product due to the tank being dropped. Also, because the recirculating fluid may spill from the tank, prepare a pan to receive it or work in a location where fluid spills can drain. Additionally, wear protective equipment such as shoes and gloves.

Stop the product (cut the power supply and cooling water) and remove the connected cables and piping before draining. Draining without stopping the product might cause the power supply to turn on unexpectedly or the piping to disconnect, which would result in a jet of water.

supply a flow over the maximum flow rate of 8L/min. Note 5) When the temperature is set high, the liquid temperature inside of the liquid tank and the

temperature inside of the thermostat could differ greatly depending on the heating mode at start-up, and the thermostat could then begin operating and stop the output.

Note 6) 1. Do not use the thermo electric bath under the condition where the circulating fluid splashes or leaks out. Otherwise, peripheral equipment as well as the thermo electric bath can break.

2. When the set temperature is increased from a low value to an ordinary value, some kinds of the circulating fluid can swell, increase and overflow, which can not only break the thermo electric bath and other equipment, but also cause a serious accident. Take a measure to prevent this situation in advance by decreasing the amount of the circulating fluid, etc.

7.4 Communication

7-12

7.4.7 Explanation of Code

STX

The code necessary for the receiver to detect the beginning of a message. It is put at the beginning of sent characters.

Address

The address to which (this product) the master communicates. The address in a response message from this product shows where the message is sent.

Content

One of two symbols, R or W.

R: Read data from the product

W: Write or store data to the product

Identification

The classification symbol (identification code) of read or written data with 3 digit alphabetical ASCII codes. Refer to page 7-18 7.4.11 Identification Code List.

Numeric data

Read or written data with 5 digits regardless of its type. Minus data: - (symbol for minus) is displayed at the 1

st digit

Position of decimal point: Not included in 5 digit data. Ex) The 5 digit numeric data 00010 means

Ex. Meaning of numerical data

Target temp., measured temp., and offset value

1.0

ETX

The code necessary for the receiver to know the message is complete. It is put at the end of sent characters (except for BCC).

BCC

Exclusive OR (EX-OR) of all characters from STX to ETX are taken in. If BCC check is set to no function in the comunication setting mode of the product, this code is not included in the response message.

ACK

The affirmation code included in the response message of the product; it is sent when the received request message contains no errors.

A_HEC-OM-J004-4

Chapter 7 Appendix

7.4 Communication

7-13

NAK

The negation code included in the response message of the

product and sent with error type information (refer to Error

type) when the received request message contains an error.

Error type

When the request message received by the product contains an error, the content of the error is included and sent subsequently to the NAK of the response message. If there are multiple errors, then the error that has been assigned the largest number is included and sent.

Table 7-3 Content and classification of errors

Error no. Content of the error in a request message

0 Memory error or controller failure It replies regardless of the content of request message.

1 The numeric data is out of the set range specified individually for each setting item.

2 Changing of a required item is prohibited or there are no items to be read.

Change prohibition occurs when

(readable) is set to a communication-mode shift setting or the measured value (PV1) is changed. PV1 can be read only,

cannot be written if (readable and writable) is selected in the communication-mode shiftsetting.

3 The numeric data is given an ASCII code other than the one for numeric data.

The position for the symbol is assigned an ASCII code other than 0 or -.

4 Format error

5 BCC error

6 Overrun error

7 Framing error

8 Parity error

9 PV error occurs during auto tuning.

Auto tuning is not completed after 3 hours have passed.

It replies regardless of the content of request message.

7.4.8 Cautions for Communication

Pay attention to the following points for communication.

Operation after the power supply is turned on

The product cannot communicate for approx. 6 sec. after the power supply is turned on. (No communication). Allow a time delay before starting communication after the power supply is turned on.

Timing for sending and receiving

Allow a time delay for response to ensure the transition between sending from the master and receiving when using RS-485 or RS-232C.

Requesting interval

When a request message is sent continuously from the master, allow an interval of 1ms or more after receiving the response message from the product.

Response requirements

The product will not send a response message if STX and ETX (BCC) are not included in the request message. That is, if the request message contains an error, the response message (to the error), including NAK and ERR, is not sent. If the response message is not returned for a significant period after the request message is sent from the master, check the message and resend the necessary request message.

Address designation error

When this error occurs, the product does not respond to a request message which specifies an address other than the set one. If the response message is not returned after a significant period, check the message and resend the necessary request message.

Number of data digits and position of decimal point

Read or written data is expressed with 5 digits, regardless of its type.

Refer to page 7-12 7.4.7 Explanation of Code.

Operation after request message to store is received

The product begins to store data after receiving a request message to store from the master. Only the data that has a different content from the EEPROM (data that has been changed) is stored. The time required for storage is approx. 6 sec. The product responds (sends an ACK) after the data storage is completed.

If the power supply is turned off during the storing process, the data might not be stored. Do not turn off the power supply before the storage completion message is received.

Storage of data other than the request message to store

When a parameter is changed with a key-in operation, the product stores all parameters into the EEPROM even if not receiving a request message to store.

Chapter 7 Appendix

7-15

Change of set value (SV) due to communication during auto tuning

The set value SV can be changed even during auto tuning. When auto

tuning (automatically or manually) is completed, the changed set value will

become valid. (While auto tuning is running, the set value does not

change.)

7.6 Calculation of Dew Point Temperature (from psychrometric chart)

Fig. 7-7 Psychrometric chart

1. Measure the ambient temperature and humidity.

2. Plot the ambient temperature on the X axis, Temp. (ex. 24 o C), and

draw a vertical line from there.

3. Find the intersection (A) between the curve with the value closestto the

ambient humidity and the straight vertical line.

4. Draw a line parallel to the X axis from intersection A and find the

intersection (B) between this line and the curve representing 100%

relative humidity.

5. Draw a vertical line to the X axis from intersection B. The temperature

at the intersection between this line and the X axis is the dew point (in

this example, 13 o C). If the temperature falls to this value, the moisture

contained in the air will begin to form condensation.
