1 Safety information

1.1 General safety information

A laboratory thermostat is used to heat, cool and circulate liquids as specified. Hazards arise from this due to high or low temperatures, fire and the general hazards due to the application of electri c al 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. with the exceeding or undercutting certain temperature thresholds or with the fracture of the container and reaction with the heat transfer liquid. It is not feasible to include all possible situations. They remain essentially subject to the judgement 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 601-1.

Classes in the EMC standard DIN EN 61326-1. Class A: Operation only on electrical supply networks without connected domestic areas. Class B: Equipment for operation on electrical supply networks with connected domestic areas. With unfavourable network conditions interfering voltage variations can occur.

4.1 Ambient conditions

Use of the thermostating unit is only admissible under the conditions stated in DIN EN 61010-1:2001 and DIN EN 61010-2-010:2003 :

− Operation only indoors.

− Elevation up to 2000 m above seal level.

− Siting base impermeable, flat, non-slip and non-flammable.

− Keep distance to walls (Ì 6.1).

− Ambient temperature (Ì 11).

The ambient temperature must be take Permissible mains voltage variations (Ì 11).

−

− Maximum relative humidity 80 % up to 31 °C and decreasing linearl

− Overvoltage Category II and transient overvoltages according to Category II.

− Contamination Level: 2.

4.2 Device types

n into account.

y to 50 % up to 40 °C.

Heating thermostats The type designation of the heating thermostats is composed of the prefix E for ECO, the approximate

bath volume in litres and a G for the GOLD device variant. Example: E 10 G is a heating thermostat with a maximum bath volume of 10 litres 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 litres and a G for the device variant GOLD. Example: ET 6 G is a heating thermostat with a transparent bath with a maximum bath volume of 6 litres

in the GOLD device variant.

Cooling thermostats The type designation of cooling thermostats is composed of the prefix R (to identify the cooling device:

Refrigerated), an E for ECO, the bath volume in litres, 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 litres and a minimum temperature of -15 °C.

4.3 Pump

All devices are equipped with a pressure pump. The pump has an output with a pivotable outflow elbow. With the bath and circulation thermostats this is joined to the pump set for external tempering 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.

In the heating range the pump operates up to viscosities of 150 mm²/s. In the controlled mode 30 mm²/s should not be exceeded.

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

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

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

4.8 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 7.5.5).

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.

Cooling times for the various cooling thermostats can be taken from the cooling curves

er is switched off whe

n a malfunction occurs which affects safety.

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

− Do not use any contaminated heat transfer liquids. Contamination of the pump chamber may lead to the pump jamming and the device then switching off.

Important There are different sorts of water!

− Tap water may be unsuitable for operation due to the calcium carbonate content. There is a risk of calcification of the stainless steel vessel.

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

− There is a risk of electrochemical oxidation with the use of frames of non-ferrous metals or non-ferrous metal samples.

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

− Due to the different electrochemical potentials of metals electrochemical oxidation may occur in the case of direct contact between the tank and a frame (e.g. copper) and the bath may corrode despite the use of high quality materials for the tank.

− TIP:

Avoid the use of this type of frame or the direct contact with this sort of frame or contact with non-ferrous metal samples and the inside of the container. Use original LAUDA stainless steel frames and commercially available frames in temperature-resistant plastics.

7.8 Programmer

The programming function enables you to save five temperature/time programs. The programs consist of several temperature/time segments. This also includes how often the program is to be run (loops). The sum of all segments of all programs can be up to 150. Step changes in temperature, i.e. the time is zero, or also temperature holding phases, i.e. the temperature at the start and end of a segment is the same, are possible. On starting the current set value is taken as the starting value of the first segment.

If the pump level is to be changed in the course of the program, then the specified pump level is entered in the respective program line. If the pump level is to remain unchanged, "0" is entered and it is indicated as "---" in the display.

− A tolerance range which is too tight can however also cause undesired delays. In particular with external control the range should not be chosen too tightly. In Segment 5 a larger tol-

erance has been entered, so that the desired time of ten minutes is maintained even with settling action p.

− 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.

The standard parameters are set as default also for the temperature stabilisation 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 behaviour.

The control system for external actual value 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 correcting quantity limit the maximum permissible deviation between the temperature on the external load and the temperature of the outflow liquid can be limited. The limit can be set via a menu point. (Ì 7.9.2.1)

7.9.2.2 Procedure for setting the control parameters for external control

1. Activating external control (Ì 7.7.1).

2. Set the slave controller:

2.1. Parameter to auto ; Xpf in dependence of:

− Check or adjust device type (Ì 9.3.4).

− Select heat transfer liquid with as low-viscosity and with as high a t

Ranking list: Water, water/glycol, oils, Fluorinert®.

− Set pump level as high as possible,

− set the circulation as strong and fast as possible,

− select the hose length as short as possible, e.g. 2 x 1 m,

− hose cross-sectional area as large as possible, e.g. ½ inch,

− set the throughput through the external load as large as possible.

2.2. Set Xpf:

− With a tendency to oscillate with a short period of oscillation (e.g. 30s) Î Xpf smaller, otherwise larger,

− with poor thermal coupling and a large mass to temper Î large (e.g. 2...5, possibly even larger),

− with good thermal coupling and a small mass to temper Î small (e.g. 0.2...0.7,

− if fast temperature changes are required, external baths should be controlled if possible with in-

ternal control. Otherwise choose Xpf to be very small (0.05 ... 0.1).

3. Setting the master controller (PID controller):

− First start with Auto, then possibly continue with manual.

3.1. Setting Kpe:

− With a tendency to oscillate (long period of oscillation, e.g. 10 min) Î Kpe larger, otherwise smaller,

3.2. Setting Tne/ Tve/ Tde:

− Generally quite high values (Tne = 70 s ... 200 s; Tve = 50 s ... 150 s),

− with smaller values Î faster transient responses, otherwise slower transient responses and

therefore less oscillation,

− Tve: To reduce transients Î increase Tve, otherwise vice versa,

− Tde (damping for Tve): generally approx. 10 % of Tve.

4. Correcting quantity limit (or outflow temperature limit) (Ì 7.9.2) and temperature limits (Til/Tih) (Ì

Analogue Module (LAUDA order no. LRZ 912) has two inputs and two outputs, which are brought out to a six-pole DIN socket to Namur Recommendation (NE28). The inputs and outputs can be set independently of one another as a

0...20 mA and 4...10 V interface, Various functions can be selected for the inputs and outputs. Accordingly, the signal on the input is interpreted differently and different information appears on the output. In addition the interfaces can be freely scaled according to the set function. 20 V DC is available for measurement transducers.

The following values can be defined via the inputs:

− setpoint temperature with the function Setpoint temperature.

− external actual temperature with the function Ext. actual temperature..

− Pump power with the function Pump pow..

The following values can be output via the outputs:

− setpoint temperature with the function Setpoint temperature.

− The temperature controlled: Controlled temp. .

− Actual temperature (bath temperature): Internal temp. .

Your ECO thermostat triggers alarms, warnings or error messages as necessary.

All warnings, alarms or error messages are shown in plain text in the display.

Alarms: Alarms are relevant to safety. Pump, heating and chiller switch off.

Warnings: Warnings are normally not relevant to safety. The device continues to run.

Errors: If a malfunction occurs, switch off the unit at the mains switch. If the malfunction recurs

after switching on the device, contact LAUDA Service Constant Temperature Equipment (Ì 9.6) or your local service organisation.

Once the cause has been rectified, alarms and wa

The device type (Ì 4.2) without the suffix "G" (GOLD) is shown in the menu under Setup Æ

Device Status Æ Type.

A type change can be carried out here in this menu point. The type change is linked to a 3 second key depression delay to prevent an unintentional type change. In this way all parameters are reinitialised, i.e. even adjusted control parameters are lost.

Automatic adaptation of Tmax to the selected device type, i.e. with the ECO GOLD thermostat Tmax = 202 °C and with the ECO GOLD with transparent bath Tmax = 102 °C.

Following this, Tmax must be re-entered manually (Ì 7.4.1), because otherwise the device goes into the

9.4.2 Inspecting the heat transfer liquid

If the heat transfer liquid becomes contaminated or degenerated, it should be renewed (Ì 6.3 and 6.4). If necessary, the heat transfer liquid should be checked for fitness for use (e.g. with a change of application),

or at least once yearly. Further use of the heat transfer liquid is only permissible if the inspection indicates this.



The heat transfer liquids should be inspected according to DIN 51529.

9.4.3 Cleaning the condenser

− The cooling circuit is largely maintenance-free. Depending on the operating time and the amount of dust present in the device environment, remove the dust from the condenser at intervals of two weeks or longer.

− To do this, remove the front grille by grasping it at the bottom with both hands and pulling the grille to the front.

− Then brush down the condenser and, where necessary, blow it out with compressed air.

− To avoid damage, remove the front grille slowly and carefully.
