PRECAUTIONS AND HAZARDS Before attempting to operate the bath read all parts of this manual carefully to insure smooth operation and avoid damage to the equipment or its accessories. If a malfunction occurs, consult section "TROUBLE SHOOTING", page 34 If a problem persists, call your supplier or Tamson Instruments B.V.
functioning properly. In case of return of the apparatus, we will only accept original packaging. INITIAL USE Before filling the bath make sure that the bath is clean. Place the bath spirit level, and connect it to the mains after the mains-switch is placed in “off” position. Use a mains-supply with proper grounding.
FILLING THE BATH The bath-fluid level must be 10- tot 20 mm below the edge of the top-plate. 10 - 20 mm Max. 60 mm In al cases the heating element must be kept fully submersed during use. A low fluid level will cause severe damage to the heating element and also cause fire when flamable bath fluid is used.

It is very important to select a liquid with a viscosity of less than 10 cSt at the operating temperature and a flash point which is well above the operating temperature. METHANOL Do not use demineralized water. This water can lead to corrosion of the bath and moving parts.

Ensure a correct fluid level. The heating element must be kept fully submersed during use. TB30 bath Bath content level must be above the heaters! When level is too low, there is great risk of fire! TLB50 Low temperature bath Bath content level must be above the heaters!

CHECK VOLTAGE FREQUENCY CONNECTING Before plugging the appartus into the mains socket, make sure the voltage of the bath corresponds to the local voltage and frequency. Use a mains supply that is well earthed, clean of USE PROPERLY interference and suitable for the acquired electrical load EARTHED MAINS of the bath.
INTRODUCTION TO THE SERIES The TAMSON baths are used for precise temperature control. This series offers a choice in multiple bath volumes, different cooling capacities and operating temperature ranges. GENERAL The TAMSON baths are constructed throughout from corrosion-resistant – stainless steel and brass materials. Outher casing is zinc plated powder coated steel.
USING THE OVERFLOW OUTLET When the bath fluid rises, excessive fluid can leave the bath via the overflow (5) outlet. This can be the case when fluid retrieves from an external load when switching off the pump. Or when (re)filling the bath fluid.

EXTERNAL PUMP To ensure uniform temperature control all models have a built in stirring mechanism. Additional to the stirring, the TLC and TTU (can) offer the possibilty to circulate fluid PRESS trough an external closed system BUTTON TO RESET MOTOR Both stirrer and pump are protected bij a fuse.
COOLING THE BATH (TTU - TB) When using the bath fluid around ambient temperatures it is difficult to realise stable temperature regulation. This is caused by the self heating of the bath due to the insulation and friction of the pump/stirrer. This can cause a raise of temperature in the bath up to 30 ..

OPERATION SWITCHING ON If the bath has been properly filled with fluid it can be switched on with the mains switch located on the front panel. Chose a working temperature (set point). CAUTION WITH POWERING ON/OFF WAIT Be careful and do not toggle with the on/off switch. To BEFORE start the cooling compressor high currents are needed TURNING ON...

The temperature displayed can be increased or decreased with an offset ranging from +5.00 down to -5.00 °C in steps of 0.01°C. This way the temperature reading on the display can be synchronised with an independent separate thermometer.

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. Delta = 0,075°C ±...
QUICK START Fill the bath with fluid to flood the heating elements and the cooling coil. However do not fill the bath fully to the maximum. Adjust the safety thermostat to the maximum working temperature. Place the power plug, and switch the bath on using the mains switch.

10.3 MANUAL TUNING The parameters for the PID control can also be changed manually. The method described below provides fast finding of the PID settings and is refereed to as the method of "Ziegler Nichols" This method provides fast manual findings of the PID values.
10.4 DRAINING BATH FLUID Before removing flammable bath liquids take the appropriate fire hazard precautions against these liquids. When draining the bath fluid, be sure that the bath fluid has cooled down to ambient temperature. If viscosity is too high at ambient temperature to remove the fluid, make sure that the hose to drain and waste container can withstand the temperature of the bath fluid.
