2.4 Piping

1) Ensure the flow rate of the recirculating fluid is as high as possible to maintain the temperature stability. Therefore, the length of the external piping should be minimized and internal diameter should be as large as possible. Piping must have sufficient strength for the maximum discharge pressure of the recirculating circuit.

2) Likewise, if a tube is bent or multiple elbow fittings are used, the piping resistance will increase and the flow rate will decrease. If the flow rate falls below 2L/min, the temperature stability will decrease.

3) If installing a tank externally, only a sealed tank should be used. Do not use an open tank.

Ensure that the INLET and OUTLET for recirculating and radiating water are connected correctly. If any valves are used ensure that they do not restrict the flow, otherwise low flow my cause an alarm.

2.5 Quality of Radiating Water

Use water that satisfies the quality standards shown below for radiating water. If other liquids are used, the product could be damaged and leak fluid, resulting in electrical shock or earth leakage.

3.5 Operating Principles

The operating principle of the product is explained below

3.5.1 Construction and Principle of Thermoelectric Module

The product controls the temperature of the recirculating fluid using thermoelectric modules (Peltier Modules).

A thermoelectric module (electronic cooling and heating element) is a device consisting of multiple semiconductor elements. Itcan perform cooling and heating using direct electric current, by placing the elements in series for electric purposes and in parallel for thermal purposes. When two different electric conductors or semiconductors elements are connected in an electrical circuit and direct current is passing trough them, thermal energy absorption or generation of the Joule effect is seen at the connecting metal junctions. This is called Peltier effect. If P-type and N- type semiconductors elements are connected in an electrical circuit using metal connections, as shown in the figure below, and direct current is passed through this circuit, heat absorption and radiation is seen at the connecting metal junctions. This effect is reversible. Heat absorption and radiation 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 stream flowing in the opposite direction to the current and the P- type semiconductor has a hole stream flowing in the same direction as the current. These electron and hole streams move heat from one surface to another.

3.5.2 Construction of temperature controlling device

Several thermoelectric modules are installed in a heat exchanger. Radiating water flows on one side of the thermoelectric module, and recirculating fluid flows on the other side of the thermoelectric module. DC output transmitted from a switching power supply is connected to the thermoelectric module, and a controller controls the DC output from the switching power supply. This control is based on the signal sent from the temperature sensor that is mounted on the outlet of the heat exchanger, achieving an accurate temperature control of the recirculating fluid.

3.6 Functions

3.6.1 Auto tuning This function sets the values necessary for the control system such as PID (proportional band, integral time, derivative time and ratio of cooling/ heating gain) automatically. *Depending on piping and other conditions, sometimes auto tuning cannot be controlled properly even if it is finished correctly.

e.g.>> The target temperature is not achieved. Hunting occurs. In that case, return to the default value or set PID constants manually referring to the following table.

Table 3-1 Setting of PID

No. Problem Setting

1 It is far from the target temperature

(1) Check the Heating/Cooling Ratio is 50 or more.If it is less than 50, correct it to 50 or more.

(2) If the value of PB range and I Constant is too large, it takes a long time to achieve the target temperature.

2 Hunting (temperatur e fluctuation) occurs.

(1) The value of PB range might be too small. Increase PB range. At that time, ARW Range should be approx. 1.1 times as PB Range.

(2) The value of I Constant might be too small.

Increase I Constant.

3.6.2 Offset function This function controls the temperature slide by an offset value from set point temperature. The range of offset is -9.99 to 9.99 C. When the recirculating fluid is carried to the target object, a certain deviation occurs between the temperature before the object and the setting temperature of the product due to the influence of ambient temperature on the piping. In this case, if the deviation is input as the offset value, the temperature of recirculating fluid just before the object can match with setting value.

Internal sensor value for alarm does not include the offset value.

3.6.3 Learning control function This function lets the product measure the temperature of recirculating fluid flowing before temperature target object by an external temperature sensor and adjusts the offset function automatically to the set value at a certain sampling interval. The external temperature sensor needs to be prepared separately by the customer.

3.6.4 External tune control function This function makes the temperature of recirculating fluid consistent to the external (ambient) temperature all the times. This function lets the product measure the temperature from a temperature sensor mounted in the customer preferred location, then it adjusts the temperature of the fluid automatically to the temperature detected by the sensor. The separate temperature sensor needs to be prepared separately by the customer.

3.6.5 Temperature sensor fine control function This is a function to finely control the measurement temperature of the control sensor within the range of -9.99 to 9.99 C separate from offset function. Control sensor can be corrected by inputting difference (calibration value) between temperature of standard and that of control sensor.

Preparation for Operation

Internal sensor value for alarm includes the fine control value.

Internal sensor value for alarm = Internal sensor value Fine control value

3.6.6 Setting value memory function

(Function that backs up with EEPROM) This function backs up all the manually set values to nonvolatile memory (EEPROM). Even if the power is turned off the set values are saved and will be restored at power on.

3.6.7 Serial Communication Function This function allows the product to communicate with a host computer or your system by serial communication that conforms to the standards of RS-485 and RS-232C. Communication is possible with the cable length of 500m for RS-485 and 15m for RS 232C. Communication allows a host computer to set and monitor operating conditions of up to 16 products (with RS-485).

The communications function allows the following actions:

Read and change the set point temperature Read the control sensor value Read the alarm status Read and set the offset value

In cases when using communication, a separate Communication Specifications is available for more details.

3.6.8 Upper/ Lower Temperature Limit Alarm Function This function raises an alarm when temperature of the recirculating fluid is out of allowable upper and lower range. When the alarm is raised, WRN is indicated on LCD. If recirculating fluid temperature returns to within allowable upper/ lower range, this alarm is automatically canceled. The allowable upper and lower range of temperature can be set between 0.1 and 10 C.

3.6.9 Warning of output interruption This function raises alarm and stop operation safely when a critical error detected (However, operation continues in case of ERR 15 and ERR 18.). When a alarm is detected, the display shows ERR and a alarm number. At the same time, the alarm is transmitted to alarm output connector with volt-free contact. This warning cannot be removed unless the power is turned off once and supplied again.

6 Preparation for Operation

6.1 Piping 6.1.1 Preparation for radiating water

The piping for radiating water is connected as below.

1) Connect fittings to the ports marked [RADIATING WATER IN] and [RADIATING WATER OUT] at the rear side of the equipment. (the same fittings should be used for IN and OUT)

[Port size ---3/8]

2) When connecting a fitting to the port, hold the port a wrench to protect the port on the product from directly receiving the

force created by the tightening the fittings. [Tightening torque --- 22 to 24Nm]

3) Apply the following flow rate of radiating water.

3L/min - 7Lmin When the flow rate of the radiating water is not enough, cooling capacity will decrease. Also, when the flow rate is extremely small, alarm (ERR14) may occur and the temperature of the radiating water might be extremely high. If resin tubing is used for piping under these circumstances, the tubing may be softened and break. Therefore, be sure to cool the radiating water and flow the radiating water with the correct flow rate.

Use fresh water such as tap water for the radiating water. If radiating water is circulated, control the quality of the radiating water to prevent corrosion of the wetted material. For quality standards for the radiating water, refer to 2.5 Quality of Radiating Water.

Keep the radiating water temperature between 10 and 35C. (No dew condensation) Note that the cooling and heating capacity is changing depending on radiating water temperature. Also, if lower-temperature radiating water is supplied, dew may condense in the product and the equipment could be damaged. Keep the radiating water temperature above the atmospheric pressure dew point. To find the dew point, refer to 9.3 Calculation of Dew Point Temperature (from a psychrometric chart).

The maximum operating pressure is 1.0MPa. Do not attach a valve at the outlet of radiating water port. Otherwise, water hammer can occur and damage the product.

Operation

6-2

6.1.2 Preparation for recirculating fluid

The piping for recirculating fluid is connected as below.

1) Connect fittings to the ports marked [RECIRCULATING FLUID IN] and [RECIRCULATING FLUID OUT] and [DRAIN] at the rear side of the equipment. (the same fittings should be used for IN and OUT)

(1) [Port size Rc 3/8] (2) [Drain Rc1/4]

2) A plug is mounted on DRAIN port for recirculating fluid. When the piping for drain is connected, remove this plug beforehand. Drain the recirculating fluid before performing any maintenance.

3) When connecting a fitting to the port, hold the port a wrench to protect the port on the product from directly receiving the

force created by the tightening the fittings. (1) [Tightening torque --- 22 to 24 Nm] (2) [Drain ----12 to 14 Nm]

4) Take off the reservoir cap of the product. Fill the recirculating fluid for the reservoir.

The inlet of the reservoir is not so large and there is a possibility of spillage of recirculating fluid. Pay attention when filling the recirculating fluid. Stop the filling once the level of fluid reaches H level. Turn on the power switch to fill the piping with the fluid. When the external piping is filled with the recirculating fluid, the level of the reservoir lowers and low recirculating fluid alarm (ERR20) arises accordingly. Then, turn off the power supply once again. Repeat the step from 5 to 7until ERR20 alarm doesnt appear any more. Then, replace the cap on the reservoir and tighten it securely. Keep the fluid level between H and L of the level indicator.

Never touch the power switch with wet hands to avoid electrical shock.

GALDEN (Solvay Solexis) and Fluorinert (3M) cant be used with this product.

Take enough care not to spill water over the case when filling the reservoir. When it is spilt by mistake, wipe it off immediately and supply the power after it has dried. If this procedure is neglected, it may cause failure of the product.

If the power switch is turned on without recirculating fluid, the pump can be activated.

(1)

(2)

Operation

6-3

The maximum operating pressure of the recirculating fluid is 0.1MPa. If pressure goes over this limit, water may leak from the tank and piping inside the thermo-con.

An operation at higher ambient temperature or temperature up/down (heating/cooling) cycle shall be avoided. The lifetime of the pump and Thermo-electric modules is shortened.

If the external piping length is too long, the built-in reservoir tank could have negative pressure resulting in deformation and crack on tank. The built-in reservoir tank is made of plastic and must be use at more than - 0.02MPa.

Once the plug is removed from the drain port, the leakage from it is possible. Therefore, seal it with PTFE seal tape etc. and ensure there is no leakage from it before operation.

When DI water is used as recirculating fluid, static electricity occurred by the flow friction may damage or malfunction the unit. To eliminate the static electricity, use metal for the piping material and grounding wire should be connected if necessary.

The level of the tank should be checked once a day and kept within the appropriate range (H to L). The level may go down due to evaporation of the recirculating fluid. When the level goes lower than L level, it may affect the performance or damage the installed pump. Operate the unit with the correct fluid level in the tank.

Select piping length and size in order to have a recirculating fluid flow more than 2L/min. If the flow is less than 2L/min the temperature stability will be poor. The product may be damaged from continually changing between cooling and heating.

Operation

6-4

6.2 Wiring 6.2.1 Power supply

The power supply shall be connected with supplied power supply cable. Before wiring confirm the power supply at factory has enough capacity and the voltage is within specified value (with reference to electrical specifications of the power supply). This product is provided with a power supply cable. The power supply cable shall be connected properly in accordance with Chapter 9 Power Supply Cable.

Do not bend, pull or bind the power supply cable with a strong force. It may damage the power supply cord or potentially cause electric shock or fire.

6.2.2 Circuit Breaker For the power source, install a breaker with a rated breaking capacity of 5kA or more.

6.2.3 Grounding Be sure to provide protective ground, which must be class D for Japan (ground resistance of 100ohm or less). PE line of the power supply cable is available for grounding. Do not hold the ground in common with the ones for equipment which generates strong electromagnetic noise or high frequency.

If the fluid with high resistivity such as DI water is used as the circulating fluid, static electricity will be generated due to the flow friction. As both Thermo-con and the customers machines might be charged by this static electricity, ground wire shall be connected to eliminate static electricity.

6.2.4 Avoidance of Parallel Wiring Avoid connecting a signal line such as for communications or external sensor or alarm in the same route as or in parallel to a power line or high voltage line.

6.2.5 Connection of Various Connectors and Power Supply Cable 1) Ensure that the power source and the power supply of the product is turned off before connecting

the various connector and power supply cable.

2) When an external temperature sensor is connected, connect the sensor with a shield cable. Use a platinum resistant temperature sensor (Pt100, 3-wiring type, class A, 2mA)

3) Connect the host to this product with a twisted pair shield cable when applying communication function.

4) For alarm output, connect it with a twisted pair cable.

Operation

6-5

6.3 CheckRepair The following checks shall be performed before operation.

6.3.1 Daily check 1) Indication of display panel: Check temperature condition and confirm whether or not the alarm

occurs.

2) Check the recirculating fluid is not contaminated. Once the fluid is contaminated, it may degrade the performance or shorten the life time. When water is used, its recommended that anti-alga agent should be used or replace the recirculating fluid about once a month as alga or bacteria deteriorates the recirculating fluid.

3) Confirm there is no leakage of recirculating fluid or no bending or crush of the piping of recirculating fluid.

4) Confirm there is no abnormal sound or smell or abnormal heating of the case.

Operation of the pump with the plenty of air left in the piping for prolonged period may cause the pump to break. Exhaust the air enough from the piping before starting operation of the pump.

Do not perform operation under the condition which lowers the flow rate significantly, such as closing the valve. Other wise, the temperature might be beyond control.

The product is damaged if the operation with temperature fluctuation is continued for long time. Please set the PID value again by using auto- tuning function.

The tank has negative pressure (air sucking sound can be heard when the lid is loosened) during operation. If the operation is continued in such conditions, the tank may be broken. If the tank has negative pressure, remove the packing at the lid of the tank, and make it an open tank. Before removing the packing, ensure that that fluid will not overflow out of the tank due to back flow after stopping operation.

6.3.2Check after seismic vibration and impact 1) Piping: Confirm there is no defect including disconnection in piping.

2) Electrical wiring: Confirm there is disconnection of the connector from the cable.

3) Mounting condition: If the Thermo-con is mounted for operation, confirm the Thermo-con is mounted securely.

4) Recirculating fluid: Confirm there is no leakage.

5) Others: Confirm there is no abnormal sound or smell or abnormal heating of the case.

Operation

6-6

6.3.3 Repair and maintenance

The repair and maintenance services of this unit are performed only at our factory. The service requiring a trip regardless of inside and outside of Japan is not provided. When returning the product for repair or maintenance service, discharge all the fluid inside the Thermo-con in order to avoid fluid leakage during transportation, and seal it.

Additionally, it is recommended to prepare spare units to minimize downtime due to those repair and maintenance services.

Drain the fluid from Thermo-con when it is returned for the repair and maintenance service. If the fluid is left inside, an accident and damage can result during transportation.

6.3.4 Abandonment

Contact an industrial waste disposal company for disposal of the product.

8.5 Troubleshooting

Troubleshooting methods when the alarm appears is explained as follows.

Table8-4-1 Troubleshooting (Part1)

Code Reason for alarm setting Cause

ERR00 (1) High level noise on the power line, ground line or temp. sensor line.

(1) Move the product to an environment with little noise, turn ON the power supply. If there is no alarm, it was caused by noise. Please consult with us.

ERR01 (1) High level noise on the power line, ground line or temp. sensor line.

(1) Move the product to an environment with little noise, turn ON the power supply. If there is no alarm, it was caused by noise. Please consult with us..

ERR03 (1) The EEPROM data was destroyed by high level noise.

(1) Move the product to an environment with little noise, turn ON the power supply. If there is no alarm, it was caused by noise. Please consult with us.

ERR04

(1) Controller EEPROM data has been corrupted due to high-level noise.

(2) Writing frequency to EEPROM exceeds product guarantee value (1,000,000 times).

(1)(2)Request a repair if the alarm cant be reset.

ERR11 (1) DC output voltage of product is reduced.

(2) Voltage sag happens.

(1) Check the power voltage is 100 to 240VAC

(2) If voltage sag lasts over specified value of 50msec, the output of DC power supply reduces and the alarm occurs. Ensure that voltage sag does not happen.

ERR12 (1) Internal temp. sensor value exceeds the high temp. cutoff temperature.

(2) Flow rate of recirculating fluid is zero.

(1) Check the set value for high temp. cutoff and confirm the temperature reaches this value.

(2) If the flow rate of the recirculating fluid is zero, the temperature of recirculating fluid cant be detected and might increase. Confirm the flow of recirculating fluid isnt stopped by valves etc.

ERR13 (1) Internal temp. sensor value is lower than low temp. cutoff temperature.

(2) Flow rate of recirculating fluid is zero.

(1) Check the set value for low temp. cutoff and confirm the temperature reaches this value.

(2) If the flow rate of the recirculating fluid is zero, the temperature of recirculating fluid cant be detected and might increase. Confirm the flow of recirculating fluid isnt stopped by valves etc.

Alarm

8-6

Table8-4-2 Troubleshooting (Part2)

Code Reason for alarm setting Cause

ERR14

(1) Radiating water temp is high or flow rate is not enough.

(2) Flow rate is zero.

(3) The pump fails.

(1) Decrease radiating water temp. and increase a flow rate.

(2)(3) If flow rate of recirculating fluid is zero, the temperature of recirculating fluid cant be measured and the temperature of heat exchanger may increase. Ensure the recirculating fluid is allowed to flow.

ERR15 (1) Cooling or heating capacity overload.

(2) Volume of recirculating fluid system is too large.

(1) If PV temp. changes when the set temp. is raised and down, it causes overload.

(2) If the volume of recirculating fluid system is too large, the change of temperature takes a long time. In this case, change overload judging time setting to avoid the this alarm.

ERR16

(Note1)

(1) The flow rate of the re-circulating fluid is 1 +/- 0.5L/min. or less. (2) The Thermo-controller is faulty.

(1) Investigate why the flow rate of the re-circulat fluid is low and take countermeasures (2) Replace the Thermo-controller with a new one, and check if it is broken. SMC can repair faulty controllers.

ERR17 High level noise entered the temp. sensor line.

Check if temperature is fluctuated due to the noise. Please consult us if it is caused by noise.

ERR18 The external temp. sensor is not mounted. For learning control or external tune control, be sure to mount the external temp. sensor.

ERR19 Capacity of recirculating fluid is too large. Adjust PID value (proportional band, ARW value, integral time and derivative time) of setting mode Level 2 by hand.

ERR20

(Note1)

(1) Fluid level of reservoir is not enough.

(2) Fluid is leaking.

(1) Refill fluid.

(2) Check all fluid connections connected with the product.

9.3 Calculation of dew point (from psychrometric chart)

Fig.9-1 Moisture air diagram

1) Measure the ambient temperature and relative humidity.

2) Plot the ambient temperature on the horizontal axis (Ex. 24 C), and then draw a perpendicular line.

3) Find the intersection (A) of the curve, which is equal to relative humidity (Ex. 50%).

4) Draw a line from point (A) parallel to horizontal axis, and find the intersection (B) of the curve for 100% relative humidity.

5) Draw a perpendicular line from the intersection at point (B) down to the horizontal axis and read the Dew Point Temperature. (13 C in this case.)

* Therefore, moisture in the air starts to condensate when the air temperature becomes lower than this temperature.
