1 Safety information

According to Paragraph 14 of the operational safety decree (BetrSichV)1, the device is a system which requires supervision. (Classification according to the Pressure Equipment Directive 97/ 23 / EC: Category I). Before being put into operation, the system must be subjected to inspection for siting, for ascertaining that the device is in order and for correct functioning. A certificate must be issued regarding this inspection, documenting the extent and the result of the inspection.

The national regulations of the respective country in which the system is sited must be followed.

Danger: This sign is used where there may be injury to person-

nel if a recommendation is not followed accurately or is disregarded.

Note: Here special attention is drawn to some aspect. May

include reference to danger.

Reference Refers to other information in different sections.

1.1 General safety information

A process thermostat is used to heat, cool and circulate heat transfer liquids as specified. Hazards arise from this due to high or low temperatures, excess pressures, fire and the general hazards due to the application of electrical energy. The user is largely protected by the application of the relevant standards. Further hazard sources can arise from the type of material for which the temperature is to be stabilized, e.g. by the exceeding or undercutting certain temperature thresholds or by the fracture of the container and reaction with the heat transfer liquid. It is not possible to include all possibilities. They remain essentially subject to the judgment and responsibility of the operator. The devices may only be used as intended, that is as described in this operating manual. This includes operation by instructed specialist personnel.

The devices are not designed for use in medical applications in accordance with DIN EN 60601-1 or IEC 601-1.

1.2 Other safety information

 Check the device carefully for shipping damage before putting into operation. The device should not

be put into operation if shipping damage has been found.

 Only connect equipment to PE grounded mains so ckets.  At higher operating temperatures, parts of the device (e.g. connection, drain points) can take on sur-

face temperatures of over 70 °C. Be careful when touching the device  Danger of burns.

 After a mains failure or after switching off the device, the device surfaces can further heat up briefly.  Use suitable hoses ( 6.2).  Check the hoses from time to time for any material fatigue. Hot liquid can e scape due to hose fracture

and become a danger to personnel and materials.

 Heat transfer hoses and other hot parts must not come into contact with the mains cable.  The following actions may start the thermostat unintentionally from the standby mode: Previously ac-

tivated timer mode ( 7.14), "Start" command via interfaces ( 8).

 Withdraw the mains plug before cleaning, servicing, repairing or moving the thermostat.  Have repairs carried out only by speciali sts. The device may only be service d by trained specialist

personnel.

 Keep to service and maintenance intervals ( 9.2.6).  Observe the permissible storage and operating temperatures ( 11).  The device should not be subjected to fire; otherwise there is the danger of an explosion.  The device may only be operated with its housing in place.  Do not site the device in areas where there are aggressive media.  Only site the device on a level surface.

8 Safety information YAWE0028 / 11/11/2016

Integral XT

 Do not put any heavy parts on the device.  The operating personnel must wear suitable protective equipment.  Do not operate the device when leaks have been found; ventilate the siting room immediately.  With pressure sensitive loads (e.g. glass apparatus) with a maxim um permissible operating pressure

below the maximum pressure of the pump (3.5 bars for water, with XT 1850 W 7.0 bars with water), the hoses of the load must be routed such that kinking or squashing is not possible. In addition, a separate safety valve must be installed to protect against faulty operation ( 7.9.4, 7.9.5 and page

34).

 When selecting the heat transfer liquid, observe the permissible temperature range.  Heat transfer liquids from LAUDA are recommended which have been tested for use with the device

( 6.2).

 Always set the over temperature cut-off point immediately according to the heat transfer liqui d used

when filling ( 7.16.1).

 If required, the heat transfer liquid should be checked for fitness for use (e.g. when changing the

method of operation), or half-yearly. Further use of the heat transfer liquid is only permissible if the inspection indicates this ( 9.3.1 and 9.3.4).

 Keep the cover of the filling point closed during operation.  Under certain operating conditions (degassing, rapid heating phases), the temperature may increase

in the expansion vessel. In extreme cases, the outflow temperature of the device is reached. If heat transfer liquids are heated beyond a certain temperature (25 °C under the fire poi nt of the heat transfer liquid), then sources of ignition must be kept away from the filling opening and overflow (and at the aeration point of the expansion tank). In such cases, a nitrogen overlay of the expansion vessel is recommended (cover XT with connection for nitrogen overlay LWZ 072).

 Degas carefully (slowly) ( 7.6.3).  It is essential to avoid gas cushions in the load sy stem. This can be done by reducing the pump pow-

er by one or two levels and checking that the level indication of the device does not increase.

 If an overflow catchments container is connected, it must be suitable (including the connecting hose)

for the maximum operating temperature. The connection hose must be securely fitted.

 The overflow must not be closed.  Draining / drain mode is only permissible with an established temperature range ( 7.7).  During operation the draina ge openings must be closed with plugs (standard accessories).  On changing the heat transfer liquid, thoroughly clean the device a nd completely drain it. It is recom-

mended that the device is rinsed with the new heat transfer liquid ( 7.8).

 It is essential to prevent the ingress of secondary liquids (e.g. via a customer's defective heat ex-

changer). Only water-cooled devices:  The return hose of the water cooling m ust be securely fixed on the outlet port in order to prevent the

hose sliding off uncontrollably, also during pressure surges.  The return hose of the water cooling m ust be fixed on the outlet port that hot cooling water cannot

splash out.  It is essential to prevent kinking or squashing of the return hose for the water cooling. Excessive

pressure can cause the cooling water hoses to tear and hot water to escape.  To prevent damages by a leakage of the cooling water system it’s recommended to use a leak-wate r

detector with shut-off valve (Aqua Stop).

4.2 Types of devices

Process thermostats

The type designation of the Integral XT Process Thermostat consists of the numerical figures for the cooling power (in kW at 20 °C, mathematically roun ded) and the minimum temperature (rounded, without arithmetical sign). The identifying let ter "H" stands for devices with a maximum operati ng temperature of 300 °C or "W" stands for water-cooled variants.

Examples: XT 750 is a device with approx. 7 kW cooling power, approx. -50 °C lowest temperature and 220 °C highest temperature. XT 350 HW is a device with approx. 3 kW cooling po wer, approx. -50 °C lowest tempera ture, 300 °C highest temperature and wat er cooling.

High-temperature thermostats

The type designation of the Integral XT High-temperature thermostat consists of the numerical fi gures for the heating power (in kW, starting from 230 V devices, mathematically rounded) and an identifying letter. The identifying letter "H" stands for high-temperature thermostats and "W" stands for watercooled variants. High-temperature thermostats with cooling wate r connection (type W) always require a cooling water supply, even if they are only used in heating mode.

Precise figures can be taken from the Technical Data (þ 11).

4.3 Hydraulic circuit and Vario pump

The hydraulic circuit in the unit partly consi st s of a pipe system through which the temperature stabilizing liquid flows under pressure.

The main components are:

All devices are equipped with an eight-level, herm etically sealed (magnetically coupled) pump. T he pump power can t example, long hoses lead to external loads.

pipe system, equalizing tank (with no flow), pump, heater and heat exchanger.

On the right side of the device outflow and return connection pieces are fitted for external loads. In the heating range the pump operates up to cinematic viscosities of 200°mm²/s. In normal op erat i on

50°mm²/s should not be exceeded. From 30°mm²/s the temperature control is optimum. The device pump connections are fitted with t hreaded connections M30 x 1.5 or M38 x 1.5 according

to DIN 3863.

Pump characteristics (þ 11).

4.4 Substances / materials

All parts coming into contact with the medi a l i quid are made of high quality material suitable f or the operating temperature. Non-rusting stainless st eel is used almost exclusively. To a slight extent brass/copper is used where the media temperature i s 200 °C maximum. Sealing materials: Graphite, copper, PTFE, FKM, polymer seals.

4.5 Temperature display, control and safety circuit

The devices are fitted with a removable command operating console with back-lit graphical display entry of the set value and other settings occurs using menu guidance via context sensitive cursor and

"soft" keys. A Pt100 temperature probe measures the outf l ow t emperature in the device. A high resolving A/D

converter processes the measurement. Further measurement processing occurs via a special control algorithm for driving the heating power actuator and the special cooling system with further me asurement transducers.

An external Pt100 can be connected via a socket (10S) for measuring an external temperature. This value can be displayed and if required, used as the controlled variable when the external controll er (master) is switched on. In this way the system c ontrol is based on the external measurement and not on the outflow temperature.

YAWE0028 / 24/06/2016 Device description 23

Integral XT

The safety system conforms to DIN EN 61010-2-010. A dual-channel system is used in which two micro-controllers monitor one another. Apa rt from the outflow temperature or temperature probe, there is a second safety temperature probe (Pt100) for t he safety circuit for switching off due to excessive temperature and for monitoring the outflow tem perature probe. This fulfills the requirements of

DIN EN 61010-2-010. The over temperature switch-off point is displayed by pre ssing the key the Master.

Changing the over temperature cut-off point: (þ 7.16.1). The level in the expansion vessel is acquired by the SelfCheck Assistant in 15 levels. If the minimum

level is undercut, the pump, heating and refrigerating machine are switched off. The behavior in the case of an excessive level can be set (þ 7.16). Dif ferent reactions can be chosen depending on the thermostatic medium.

With low level, over temperature or other alarm s t he S el fCheck Assistant switches the heater off on all poles. The pump and the refrigerating machine are also switched off.

This fault switch-off remains, i.e. once the fault has been rectifi ed the alarm must be released with the

reset key Other device functions are described in the corresponding sections and in Section 7 (Starting up).

4.6 Programmer and ramp function

The units are equipped with a programmer function which enables five temperature/time programs to be saved. Each program consists of a number of temperature/time segments. These also include details of how often the program is to be executed. Up to 150 segments can be distributed amongst the fiv e programs (þ 7.12).

With the ramp function a rate of change can be direct l y entered in °C/unit time.

4.7 Interfaces

As standard, the device is fitted with the foll owing sockets:

• One socket (10S), for an external Pt100 temperature sen sor.

• Two sockets (70S), for the Command remote control and for LiBus Components.

• An RS232/RS485 interface (65S) at the back of the Command remote control.

24 Device description YAWE0028 / 24/06/2016

Integral XT

When the fault circuit trips, the refrigerating unit is also switched off.

4.8 Interface modules (accessories)

5. Profibus (LAUDA Order No. LRZ 917).

Further details can be found in the operating inst ructions YAAE0020 of the Profibus Modules.

4.9 Refrigerating unit

The refrigerating machine mainly consists of one or two fully hermetically sealed compressors. The dissipation of the condensation and motor heat takes place via a fan-ventilated laminated condenser. Here, fresh air is drawn in at the front of the unit, heated towards the back and output at the side. To ensure proper air circulation the ventilation slots must not be restricted. (þ 6.1). The condenser must be cleaned regularly to prevent soiling (þ 9.3.2.1). The SelfCheck Assistant outputs a warning signal when the condenser is soil ed.

On water cooled devices the heat dissipation takes place via a plate-type heat exchanger or a bundle tubing heat exchanger using cooling water. Regular cleaning is also required here depending on the water contamination (þ 9.3.2.2).

The compressors are equipped with over temperature cutouts which respond to the compressor temperature and the compressor current consumption. In addition the refrigerating system is ba cked up by a pressure control device against over pressure. The refrigerating unit is normally switched in aut om at ically, but can be switched manually via the operat i ng menu (þ 2.2).

Risk to the environment due to oil contamination of the cooling water circuit

With a leaky condenser there is the danger that refrigerating machine oil from the coolant cir cuit of the cooling thermostat can pass into the cooling water. Follow all the legal requirements and the regulat i ons of the water supply utility which apply at t he poi nt of use.

Water pollution due to leakage

To avoid pollution due to a leak in the cooling water sy st em it is recommended that a leakage-water detector with a water cut-off is installed.

− The devices are rated for use with non-flammable and flammable liquids according

to DIN EN 61010-2-010. The temperature in the expansion tank must not rise more than 25 °C below the flash point (þ 1.2).

− With the use of heat transfer oils note that they expand on heating (approx. 10%/ 100 K).

− Set the lower and upper temperature limits (þ 7.10.2) such that the li m i ts for the heat transfer liquid are not infringed.

− Close the drain taps. 1 tap for XT 150, XT 250W ... up to max. 4 taps with XT 750 H and larger.

− Check whether the sealing caps on the drains (1 to 4 depending on the thermostat) are tight. Tighten only slightly with an open-ended wrench (AF19).

− With this program the following parameters are automatically set:

• The pump level is set to Level 2. The pump level should only be changed when neces-

sary (þ 7.9.3).

• The heater power is reduced, round about 50 % (þ 7.15.7.1).

• The cooling unit is switched off (þ 7.15.7.1). The outflow temperature may rise above

the setpoint due to the heat input from the pump.

• Pressure control is not recommended (þ 7.9.4). Take care to the selection of the pump level with pressure sensitive loads (e.g. glass apparatus). Pay attention to a maximum permissible operating pressure.

− As with venting, the pump switches off briefly every 45 seconds for im proved degassing.

− With units up to 300 °C, after briefly switching the pump off, switching occurs between the

cooling unit and the high temperature cooler un der certain operating conditions. So that it can be ensured that both, the cooling unit and the hi gh temperature cooler are degassed. In addition, flushing occurs every 20 K.

− To simplify the removal of low-boiling solvents during out gassing, i t may be practical to open the cover of the filling point so that the vapor can escape more easily (use air extraction if required). In this operating state, check the devi ce continuously; it is essential to keep sources of ignition away from the filling aperture and t o protect the operating personnel from splashes (e.g. place the cover diagonally on the filling ape rt ure). Appropriate protective equipment and clothing must be worn. Close the cover again at the end of degassing.

− The end of degassing is reached when the outflow temperature has approached the set temperature (<10 K) and does not increase furthe r. Similarly, the end of the degassing is reached when the outflow temperature has exceeded the set temperature due to self-heating.

− Terminate the degassing program with the softkey Stop . The device is then in the standby mode. All the above described parameters are res et to the previous settings.

7.6.3.2 Permanently and automatic degassing

− The device carries out the degassing permanently and automatically further on. When the device finds gas, first the heating and cooling power is r educed or sometimes completely switched off. If the pump pressure falls signifi cantly (clear sign of degassing), the pump speed is limited, and the pump may switch off briefly. The device then starts up again automatically.

− With devices up to 300 °C and after the pump switches off briefly, swit chover occurs between the cooling unit and the high temperature cool er in certain operating conditions. This ensures that both the cooling unit and the high temperature cooler are degassed.

Draining residues XT 150, XT 250 W

After draining, liquid residues may still be l ocat ed in the return hose. Proceed as follows:

1. Remove t he return hose from the load.

2. Empty the residue from the hose into a container.

7.8 Changing the heat transfer liquid and internal cleaning

After draining there are residues of heat transfer liquid in the device depending on the type of liquid was used.

Remove these with the following cleaning proced ure:

1. Connect a short-circuit hose to the outflow and return (þ 2.3).

2. Fill the device with a suitable cleaning liquid whilst operating in the filling mode (þ 7.6). If water with a cleaning agent (fat solvent ) is used, it is essential to ensure that the device is o nly operated in the filling mode (refrigerating machine is therefore off). Otherwise there is the risk that the device may ice up internally and be damaged.

Suitable cleaning liquids for

Acetone (solvent)

It is essential to follow the relevant safety pre cauti ons when using acetone!

Water Kryo 30

3. Drain (þ 7.7) and remove the short-circuit hose. Dry the device with compressed air. To do this, carefully allow compressed air to flow into the device, alternately via the outflow and return. If cleaning is carried out with liquids which readily dissolve oil, such as acetone, do not let the unit stand dry or transport it dry for a longer period (more than one day), because the pump requires a minimum lubrication. Therefore, continue with point 4.

4. After cleaning, fill with new heat transfer liquid and vent (þ 7.6).

5. If contamination is still found (remove 0.5 liters with draining program (þ 7.7)), it is recommended that the new heat transfer liquid is again changed and cleaned externally, or the residues of the old heat transfer liquid are separated.

If residues of an old heat transfer liquid are not removed and remain in the device and the device is then operated above the thermal lo adi ng limit for this heat transfer liquid,

deposits may form, particularly on the heaters, which reduce the performance capacity

With this function it is possible to define a minimum a nd m aximum outflow temperature in the range of which the device controls as a maximum. When the temperature limits are attained, the heater or the refrigerating machine is switched off and a warning output is given. The thermostat controls down (breakaway) already 2 K before the limits. Thus the entry of a setpoint value can be prevented which would heat or cool the heat transfer liquid too strongly without a device switch-off occurring (cf. the Sect i on “Overtemperature protection” (þ 7.16.1)). If, for example, Kryo 30 is used as the heat transfer liquid, 90 °C is the maximum temperature and -30 °C the m i ni m um temperature.
