  • Page 24: Before Putting The Device Into Operation

    Before putting the device into operation Please note: The device can be operated up to an ambient temperature of 40 °C. A higher ambient temperature can have a negative effect on the cooling output of the thermostats used. When putting the chiller into operation after a lengthy shut-down, up to 30 minutes may pass until the rated refriger- ating power is available depending on room temperature and device type.
  • Page 25 Control head drops into bath Electric shock hazard Make sure that the control head mounting is securely joined  Warning! to the bath. Operation with cooling coil For the optional operation with the cooling coil (LCZ 0720 and LCZ 0721) mount the cooling coil as follows: Cut the thread with the enclosed screw Cut the thread on the holed flange already before assembly.
  • Page 26 Assembly as immersion thermostat Place the bath vessel on a flat surface. The control head is already screwed to the bath bridge. In the rear part of the bath there are two slots present on the bath edge. Guide the prongs of the bath bridge into the slots to the right and left from the rear of the bath.
  • Page 27 Assembly as cooling thermostat Notice Falling / toppling equipment Property damage Do not tilt the cooling device during transport and never turn  it upside down. After transport, site the device in place where possible two hours before putting it into operation so that, if necessary, oil deposits can form again and the compressor can develop its maximum pow- Do not cover the ventilation openings.

Do not bend the tube! Hold up with open-end wrench SW 14 mm. Please move the connecting screws for adjustment of the cylindrical chamber always gradually (about 2 rotations).
  • Page 29 Switch the button for the distribution of the pump flow to “EXT”. The position gives the greatest flow in the external circuit (cylindrical chamber). Maintenance of the calibration thermostat For cleaning purposes and check-up of the bath liquid, we recommend lifting the front cover with the chamber as follows: Remove the connecting flange and release the screws M4.

  • Page 30: Connection Of External Consumers

    Connection of external consumers For heating thermostats a pump connection set is available as an accessory ( 9) for the connection of an external consumer. This pump connection set is included as standard with cooling thermostats and with the heating thermostats E 4G and ET 15 G.
  • Page 31 Turn the pump output downwards for external bath circulation. Fit the hose section of the pump connection set onto the outflow elbow and place the pump connections in the position of the removed blind flange. Push the holed flange under the pump connections and fasten it with two cross-head screws to the underside of the control head.
  • Page 32 Operation as circulation thermostat To ensure the greatest volume flow, with operation as a circulation ther- mostat ensure the shortest possible hose connections with the largest possible hose internal diameter. Connect a hose with 11 – 12 mm inside diameter ( 6.4) to the pump connections.

The bath vessels of the LAUDA ECO thermostats are produced in stainless steel 1.4301 and are accordingly re- sistant to mechanical and chemical stresses.
  • Page 36 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 transfer liquids and hoses are general figures which can be tightened due to the oper- ating temperature range of the devices.

  • Page 95: Graphical Display Of Temperature Measurements

    Graphical display of temperature measurements From the main menu window you access the graphics window by pressing (DISPLAY). The temperature traces are shown in different colors. set-point temperature (grey) internal bath temperature (green). external bath temperature (blue). You can change the settings for the graphics window in the submenu Graph.
  • Page 96 With Rec. Interval you define the time interval between recorded tem- perature measurements (the values in brackets state the maximum recording time). The menu offers five options. With Time axis you can define the temporal range over which the meas- urements are to be displayed.
  • Page 97 With Temperature Limits you can display and manually input the tempera- ture limits for the graphical display. Temp.Scale Min Displays current minimum value Temp.Scale Max Displays current maximum value When Temp.Scale Max Temp.Scale Min (as in the illustrated example) has been selected, the entry window appears. The minimum and maximum possible temperature values and the current minimal temperature value are displayed.

  • Page 98: External Control

    External control The devices can also be optionally controlled via an external Pt100 temperature sensor, which can be connected at the back of the control head. It is necessary to install an external Pt100/LiBus module ( 6.7) for external control ( 18.2).

  • Page 99: Setpoint Offset Operating Mode (Diff.set/Actual)

    16.3 Setpoint offset operating mode (Diff.set/actual) It is possible to apply an offset value to the temperature, which is provided by an external temperature sensor and to process it as the set value. The bath temperature can therefore be operated, for example, -15 °C below the temperature of a reactor measured by the external temperature sensor.

  • Page 100: Programmer

    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 program- mable 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.

When the cursor is located on a segment number, using you return to the menu level of the programmer without changes. Note: No time specification is possible in the start segment. The temperature of the first segment is attained as quickly as possible in order to switch to segment 2 after reaching the set tolerance.
