Fig3-3 Mounting

Be sure to correctly tighten all screws the required torque.

3.4 Piping

1) Ensure the flow rate of the circulating 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 circulating 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, 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 circulating fluid is connected

correctly. If any valves are used ensure that they do not restrict the flow,

otherwise low flow my cause an alarm.

3.5 Handling

Transport Thermo-con with both handles.

4.6 Functions

4.6.1 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.

4.6.2 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 circulating 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 circulating fluid just before the object can match with setting value.

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

4.6.3 Learning control function

This function lets the product measure the temperature of circulating 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.

4.6.4 External tune control function

This function makes the temperature of circulating 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.

4.6.5 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.

Internal sensor value for alarm includes the fine control value.

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

4.6.6 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.

4.6.7 Upper/ Lower Temperature Limit Alarm Function

This function raises an alarm when temperature of the circulating fluid is out of allowable upper and

lower range. When the alarm is raised, WRN is indicated on LCD. If circulating 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.

Preparation for Operation

HEC002-A/HEC006-A 7-1

7 Preparation for Operation

7.1 Preparation for circulating fluid

The piping for circulating fluid is

connected as below.

1. The piping for circulating fluid

is located at the left side face.

2. The same fittings are used for IN and OUT of the

circulating fluid.

The fitting which can mate them needs to be prepared separately. When the fitting is connected, be

sure to hold the fitting (block) mounted at Thermo-con with spanner, etc.

Thread size of fitting for circulating fluid:

HEC002-A; Rc1/4

HEC006-A; Rc3/8

A plug is mounted on DRAIN port for circulating fluid. When the

piping for drain is connected, remove this plug beforehand.

Drain the circulating fluid before performing any

maintenance.

Width across flat of plug: 6mm

DRAIN port size: Rc1/4

Fluid other than water is not to be used as circulating fluid. Using such a

fluid might lead to fluid leakage and damage of the pump.

If a tank released to atmosphere is mounted outside, minimize the

piping resistance at RETURN of circulating fluid. If the piping

resistance is high, the causing the built-in reservoir of Thermo-con can

have negative pressure resulting in deformation and crack. The built-in

reservoir of Thermo-con is made of plastic and must not be subject to

negative pressure larger than -0.02MPa.

Once the plug is removed from the drain port, the leakage from it is not

guaranteed. Therefore, seal it with PTFE seal tape etc. and ensure there

is no leakage from it before operation.

Preparation for Operation

HEC002-A/HEC006-A 7-2

7.2 Power supply

The power supply shall be connected with attached power supply cable.

Confirm the power supply at factory has enough capacity and the voltage is within specified value

beforehand (with reference to electrical specifications of the power supply). This unit is provided with the

power supply cable. The power supply cable shall be connected properly in accordance with Chapter 10

Power Supply Cable.

Electric specifications of the power supply

7.3 Grounding

Be sure to provide the grounding. Use medical plug with protection earth when the unit is used for medical equipment. 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.

7.4 Supply circulating fluid and drain

1. Confirm the power switch is turned off.

2. Take off the reservoir cap of the product.

3. Fill the circulating fluid for the reservoir. The inlet of the

reservoir is not so large and there is a possibility of spillage

of circulating fluid. Pay attention when filling the circulating

fluid.

Stop the filling once the level of fluid reaches H level.

4. Turn on the power switch to fill the piping with the fluid.

5. When the piping is filled with the circulating fluid, the level of

the reservoir lowers and low circulating fluid alarm (ERR20)

arises accordingly. Then, turn off the power supply once

again.

6. Repeat the step from 3 to 6 until ERR20 alarm doesnt

appear anymore. Then, replace the cap on the reservoir and

tighten it securely.

7. Keep the fluid level between H and L of the level indicator.

8. Water pressure during normal operation becomes under 0.1

MPa.

1. Drain circulating fluid from the drain port. Open the reservoir cap would be helpful for draining.

2. To drain from the piping, blow the air (0.1MPa, about 1 minute) from Fluid IN to Fluid OUT. Tighten

the tank lid and drain port while blowing

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

Preparation for Operation

HEC002-A/HEC006-A 7-3

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.

Take enough care not to spill the feed water over the case when

supplying water to the reservoir. When it is spilt by mistake, wipe it off

immediately and supply the power after it dries. If this procedure is

neglected, it may cause breakdown of the equipment.

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.

If the fluid with low conductivity such as DI water is used as circulating

fluid, it causes static electricity due to friction and damages the

temperature sensor and other electric components of this unit. Take a

measure to minimize static electricity from circulating fluid.

If the power switch is turned on without circulating fluid, the pump is

damaged.

The product is damaged when driving for a long term with the

temperature staggered periodically after reaching the target temperature.

Please set the PID value again by using auto-tuning function (see

section 5.3).

7.5 CheckRepair

The following checks shall be performed before operation.

7.5.1 Daily check

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

occurs.

2) Filter : Confirm there is not attachment of the dust on the filter at suction port. A lot of attachment

may impair performance. We will recommend the removal of dust once every three months.

3) Check if the circulating fluid is dirty. Dirty circulating fluid may result in worse capacity or shorter

product life. If water is used as the circulating fluid, algae and bacteria will be generated and dirty

the circulating fluid. Therefore, replace the circulating fluid regularly (once a month as a guide).

4) Confirm there is no leakage of circulating fluid or no bending or crush of the piping of circulating

fluid.

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

Preparation for Operation

HEC002-A/HEC006-A 7-4

Remove the dust attached to a filter by vacuum cleaner to prevent

degrading of performance. The recommended interval of removal is

once per 3 months. Do not use water or boiled water since it leads to

generation of rust at a frame.

If the thermo-con is operated with bacteria and algae present, its cooling

capacity or the capacity of the pump may deteriorate. Replace all

circulating fluid regularly according to the conditions of water quality

(once a month as a guide).

7.5.2 Check 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) Circulating fluid: Confirm there is no leakage.

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

7.5.3 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. Also, when this unit is returned for these

purposes, drain the fluid from Thermo-con.

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.

After washing with DI water, return the product when the fluid was other

than water. The acceptance might be refused according to the state of

the product.

(2) Remove foreign matters which might stop the

fan.

(3) The inside of the power supply can get hot.

Eliminate the dust on the filter.

(4) 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 circulating fluid is zero.

(1) Check the set value for high temp. cutoff

temperature and confirm the temperature really

reaches this value.

(2) If the flow rate of the circulating fluid is zero, the

temperature of circulating fluid cant be detected

and might increase. Confirm the flow of circulating

fluid isnt stopped by valves etc.

ERR13

(1) Internal temp. sensor value is lower

than low temp. cutoff temperature.

(2) Flow rate of circulating fluid is zero.

10.2 Calculation of dew point (from psychometric chart)

Fig.10-1 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.
