ECO GOLD

3 Device description

3.1 Device types

Heating thermostats The type designation of the LAUDA heating thermostats is composed of the prefix E for ECO, the ap-

proximate bath volume in liters and a G for the GOLD device variant. Example: E 10 G is a heating thermostat with a maximum bath volume of 10 liters in the GOLD device

variant. With the heating thermostats with a transparent bath there is the prefix of ET for the ECO transparent

bath, followed by the bath volume in liters and a G for the device variant GOLD. Example: E 6 G is a heating thermostat with a transparent bath with a maximum bath volume of 6 liters

in the GOLD device variant. Cooling thermostats

The type designation of LAUDA cooling thermostats is composed of the prefix R (to identify the cooling thermostat: Refrigerated), an E for ECO, the bath volume in liters, the minimum attainable temperature (without arithmetical sign) and a G for the device variant GOLD.

Example: RE 415 G is a heating thermostat with a maximum bath volume of 4 liters and a minimum temperature of -15 °C.

Where applicable the type designations are supplemented by a W for "water-cooled" and/or N for "Natural refrigerant".

3.2 Pump

All devices are equipped with a pressure pump. The pump has an output with a pivotable outflow elbow. With the heating thermostats this is joined to the pump connection set for external temperature control circuits. An additional output is used for internal bath circulation. By switching the selector at the front on the control head, the flow can be manually selected or divided between the two outputs.

Using the operating menu, one of six flow-rate levels can be selected for the pump. For thermostats with a small bath a power level of 1 to 3 is practicable.

When operated as a circulation thermostat with an external consumer, a higher power level is practicable to keep the temperature difference between the bath and external consumer small even a hig her temperatures.

The pump connection of the outflow can be closed without any detrimental effects on the pump.

equipment line and other accessories, such as a solenoid valve for cooling water control or a reverse-flow protection device.

3.6 Chiller

The chiller mainly consists of a fully hermetically sealed compressor. The dissipation of the condensation and motor heat takes place via a fan-ventilated lamellar condenser. Here, atmospheric air is drawn in at the front of the device, heated up and discharged at the back and sides. To ensure proper air circulation the ventilation openings must not be covered up.

The compressor is equipped with a thermal release which responds to the compressor temperature and current consumption. The chiller is normally switched in automatically, but can also be switched in manually via the operating menu (Ì A.3).

er i

The chill The Cooling Thermostat RE 1050 G is equipped with the SmartCool technology which makes optimum

use of the compressor and only chills when cooling output is demanded by the controller. To achieve this, several sensors in the cooling circuit monitor the operating status.

6.4 Heat transfer liquids, cooling water and hoses

Note:

− Tap water is unsuitable for operation with the thermostat due to the calcium carbonate content. The bath vessel may calcify.

− High purity water (from ion exchangers) and distilled or bidistilled water are unsuitable for operation due to the corrosive properties of these media. High purity water and distillates are suitable as a medium after the addition of 0.1 g of soda (Na

− Water containing iron (rust formation), chlorine (pitting) and untreated river water ("algae formation") is unsuitable.

− The bath vessels of the LAUDA ECO thermostats are produced in stainless steel 1.4301 and are accordingly resistant to mechanical and chemical stresses.

− Metals have different electrochemical potentials. Therefore, in the case of direct contact between the tank and a frame (copper for example) electrochemical oxidation may occur. The bath corrodes despite the use of high quality materials on the tank. Avoid the use of this type of frame or direct contact with it or contact with non-ferrous metal samples and the inside of the container. Use original LAUDA stainless steel frames or commercially available frames in temperature-resistant plastics.

 At higher temperatures vaporization losses occur. In this case use a bath cover (Ì 9). Use distilled water or pure

demineralized water only after adding 0.1 g of soda (Na2CO3 sodium carbonate) per liter of water. Otherwise there is the risk of corrosion!

 The proportion of water reduces with longer working at high temperatures and the mixture becomes fla mmable

(flash point 128 °C). Check the mixing ratio using a hydrometer.

 Do not use in conjunction with EPDM hose.

Never use silicone oil with silicone hoses. EPDM hose is not

suitable for Ultra 350 nor for mineral oils.

− When choosing the heat transfer liquid, it must be noted that at the lower limit of the operating temperature range impairment of the heat transfer properties is to be expected due to the increasing viscosity. Therefore, only use the full operating temperature range where necessary.

− The working ranges of the heat carrier liquids and hoses are general figures which can be tightened due to the operating temperature range of the devices.

− Never use contaminated heat transfer liquids. Contamination of the pump chamber may lead to the pump jamming and the device then switching off.

− Pay attention to the safety data sheet for the heat transfer liquid.

− Follow the regulations for disposal of the used heat transfer liquid.

If required, you can request the safety data sheets at any time. (Ì 8.7)

b) Cooling water

Certain requirements are placed on the cooling water with regard to purity. Depending on the cooling water contamination, a suitable method of purification and/or treatment of the water must be employed. The condenser and the complete cooling water circuit can become blocked, damage d and leaky due to unsuitable cooling water. Extensive consequential damage may arise on the whole cooling circuit. The cooling water quality depends on local conditions. If a fault or damage occurs due to unsuitable water quality, it is not covered by our guarantee.

Important: Danger of corrosion of the cooling water circuit due to water of unsuitable quality.

• Free chlorine (e.g. from disinfectants) and water containing chlorine lead to pitting in the cooling wa- ter circuit.

• Distilled, deionized or demineralized water is unsuitable due to its corrosive properties and leads to corrosion in the cooling water circuit.

• Seawater is unsuitable due to its corrosive properties and leads to corrosion in the cooling water circuit.

• Water containing iron or iron particles leads to rust formation in the cooling water circuit.

• Due to the high lime content hard water is not suitable for cooling and leads to calcification in the

cooling water circuit.

• Cooling water with suspended matter is not suitable.

• Untreated and unpurified river or cooling tower water is not suitable due to its microbiolo gical con-

tent (bacteria), which can become deposited in the cooling water circuit.

• Putrid water is not suitable.

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 refrigerant circuit of the cooling thermostat can pass into the cooling water. Follow all the legal requirements and the regulations of the water supply utility which apply at the point of use.

Water pollution due to leakage

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

E Programmer

The programming function enables you to save five temperature/time programs. The programs consist of a number of temperature/time segments and details about their repetition. The total number of freely programmable segments is 150. Temperature step changes (time is zero) or also temperature retention phases for the same start and end temperatures in the segment are possible. On starting the current set value is taken as the starting value of the first segment.

Changes to the pump level are entered in the relevant line. If the pump level is to remain unchanged, "0" is entered (display shows "---").

− Only flat (slow) ramps should be programmed where necessary with a tolerance range. Steep

ramps which lie close to the maximum possible heating or cooling rates of the thermostat may be severely delayed by a tolerance range that is too tight (here in Segment 2) q.

• Creating and editing a program.

• Insert or append a new segment.

• Delete a segment.

Note:

− New segments and be inserted and existing ones changed, also the currently active segment, even when a program is currently being executed. Furthermore, except for the currently active segment, all segments can be deleted at any time.

− Changes to the currently running segment are possible. The segment is continued as though the change has been valid since the start of the segment.

− If the new segment time is shorter than the already expired segment time, then the program skips to the next segment.

− If a segment time is required > 999h: 59min, then this time must be spread over several consecutive segments.

F Control parameters

The control parameters have been optimized at the factory for operation as a bath thermostat (with water as the heat transfer liquid) with internal control. The standard parameters are already set as default also for the thermostatic control of external applications with external control. Depending on the application, the configuration can be adapted from case to case as required. Also the thermal capacity and the viscosity of the heat transfer liquid affect the control behavior.

Note: Only change the control parameters if you have adequate knowledge of control tech niques.

F.2 External control variable

The setting options illustrated in this section are only possible with a connected external temperature sensor or with an existing module (as activated as control variable in Section D.1) for reading in the actual temperature.

The control response to setpoint changes. From the temperature setpoint and the external temperature, which is generally measured by the external Pt100, a "master controller" determines the "internal setpoint" which is passed to the slave controller. Its set value controls the heating and cooling.

Correcting quantity limit

If a step change in set-point temperature is specified, the optimum control might set an outflow temperature which is substantially higher than the temperature desired on the external vessel. With the correction limitation the maximum permissible deviation between the temperature in the external consumer and the temperature of the outflow liquid can be limited. The limit can be set via a menu point (Ì F.2.1).

These parameters can be set on the master controller (PIDT or external controller):

These parameters can be set on the slave controller (P-controller):
