  • Page 4: Safety And Warnings

    SAFETY AND WARNINGS Make sure before installing or operating the equipment to read and understand all instructions and safety precautions listed in this manual. If there are any questions concerning the operation of the equipment or about the information given in this manual, please contact your local dealer or our sales department first.

  • Page 5: Precautions And Hazards

    PRECAUTIONS AND HAZARDS Before attempting to operate the bath read all parts of this manual carefully to ensure proper operation and avoid damage to the equipment or its accessories. If a malfunction occurs consult the section trouble shooting found on page 24 of this manual. If the problem persists, call your supplier or Tamson Instruments b.v.

  • Page 6: Installation

    INSTALLATION Important Tamson Instruments b.v. is not responsible for any consequential damage or harm caused by using this bath. Repairs on the electrical system of the bath may only be carried out by well trained and authorized persons. Tilting Before unpacking inspect the tilt watch located on the outside of the packing.
  • Page 7 Placement and ventilation 20 CM 10 CM 10 CM Air circulation has to be enabled by 10 cm of free space at both sides and 15 to 20 cm at the rear of the bath. AIR FLOW The bath has to be placed in a well ventilated area. Tamson Instruments bv VAT: NL 80 66 34 984 B01 Van ’t Hoffstraat 12...
  • Page 8 Airflow Air must pass the apparatus freely. The air transports the heat from inside the apparatus to the environment. When airflow is blocked the apparatus will not perform to its specifications and it may harm the equipment or even cause mechanical damage. Dust Do not place the bath in a dusty environment.
  • Page 9 Bath liquids The bath must be filled with a liquid suitable for the VISCOSITY minimum operating temperature. < 10 mm²/s FLASH POINT > OPERATING TEMP. It is very important to select a liquid with a viscosity preferably less (e.g. 3 mm²/s) at the operating temperature and a flash point which is well above the operating temperature.
  • Page 10 Extreme HAZARD Methanol: Do not use methanol at temperatures above 20°C. Do not The methanol will vaporise and cause toxic and operate > flammable vapours. Explosion hazard can build up 20ºC in or around the bath When working at temperatures above 20°C, oil or water can be used as an alternative.
  • Page 11 4.7.2 Maximum level Caution: When using methanol one must be worn that the Max. level: fluid shrinks dramatically when cooled down. If the 1 cm below bath is filled at these low temperatures up to its top lid maximum level the bath will overflow when heating If the fluid level is too high, it will leave the bath via the overflow outlet (10mm outer diameter pipe) placed on top on the left hand side of the bath.

  • Page 12: Check Voltage

    When operating at high temperatures the lid (of the bath), top plate and the window section of the bath become very hot. Always use heat protective gloves. Care must be taken when placing or re- moving material from the bath. WEAR HEAT PROTECTIVE GLOVES...
  • Page 13 If full heat removal capacity is used at 0°C over 2 kW (TV4000LT, 3 kW TV7000LT) of heating should be applied, instead of the current 300 Watt.

    Alarm high, press button to reset Alarm low, press button to reset Window heating The TV4000LT and TV7000LT have heated windows to prevent build up of condensate. The heating is thermostat driven and kept around 50-49°C. If heating is off and the inner bath cooled down, the outside window also will drop in temperature forming a cold surface.
  • Page 17 Menu items Use the turn-push button to select a menu item and select the item by pressing the button. After pressing a sign appears next to the value indicating the value can now be changed. Pressing the button again activates the value immediately.
  • Page 18 7.1.3 Menu item "Max Power" (press: low, med, hi, max) Limits the applied power by a maximum value: Maximum of 25% applied Medium Maximum of 50% applied High Maximum of 75% applied Maximum 100% power is applied Limiting the power can be used to lower overshoot temperature..
  • Page 19 If there remains an offset in the temperature readout try to increase the I to 25 or 50. The offset is due to the PID setting and depends on the applied power percentage. An offset of 0.1°C can be adjusted with the offset value available in the menu or when increasing the PID integrator value to 25 or 50.
  • Page 20 PID configuration The two graphs below show the influence of the integral setting. The graph on top has a setting of 200 for the integral parameter. The bottom graph has a setting of 16. The value of 200 causes less stable control. I = 200 I = 16 Tamson Instruments bv...
  • Page 21 Manual tuning The temperature control of the bath is based on a digital PID system. When using different fluids in the bath each with their own heat capacity, the use of external cooling external connected processes(circulation), working at different set point temperatures requires new settings of the PID parameters.

  • Page 22: Maintenance

    MAINTENANCE Drain bath liquid The bath can be emptied via the drain tap located at the left side of the apparatus. For safety reasons the tap can only be opened by using a screwdriver. The thread SCREWDRIVER inside the tap is 3/8". TO OPEN DRAIN 3/8"...
  • Page 23 Regularly check the apparatus and condenser unit for dust. Remove dust with a vacuum cleaner. Do NOT remove dust with compressed air. Remove panel from TV4000LT or TV7000LT. Use vacuum cleaner to remove dust. 4 x screw Tamson Instruments bv VAT: NL 80 66 34 984 B01 Van ’t Hoffstraat 12...

  • Page 24: Troubleshooting

    When this problem occurs more often it will indicate that dust is blocking the condenser circuit. Clean the inside of the TV4000LT / TV7000LT and remove all dust from the condenser unit and fan with a vacuum cleaner. Do not use pressurized air to remove dust. The flying dust...
  • Page 25 Temperature not stable - Restart system (option from menu, see menu item "Restart" page 19 ) - Place top lid on the bath. - Check PID settings. When PID settings are incorrect the system can start to be unstable. Graph (SP-40 PID25-200-0) shows unstable control at -40°C due to a high setting of I=200.
  • Page 26 Bath temperature does not drop - Check set point setting (option from menu, see menu item "Setpoint" page 17 ) - Restart system (option from menu, see menu item "Restart" page 19 ) Faulty temperature reading / temperature offset The temperature read out on the display does not correspond to the temperature measured.
  • Page 27 9.10 It takes long to reach the new bath temperature - There is a possibility to cool down rapidly by entering the minimum set point of -40°C. Both compressors are switched on and the systems cools down fastest. When the compressor reached a temperature just 1 degree below the desired SP, set the new SP.
