2 Function

2.1 BD (E2)

The BD (E2) chamber gives the possibility to heat up the chamber to a maximum temperature of 100°C. The measuring of the temperature will be realized by a PT100 temperature probe which is placed directly in the inner of the chamber .

The controller R3 measures the resistance of the PT100 temperature probe and compares the incoming signal with the actual engaged value and decides to give a Signal to activate the heating elements or not.

PT100 –> Controller R3 à Solid State Relay à Heating Element

114,380 Ω. To measure the resistance, disconnect all three cables from the controller and measure between the white cable and one of the red cables, don’t measure between both red cables.

PT100 –> Controller R3 à Solid State Relay à Heating Element

The PT100 temperature probe is a resistance-measurement system. This means that the PT100 changes his resistance at different temperatures. For example: at 37°C, the resistance of the PT100 have to be 114,380 Ω. To measure the resistance, disconnect all three cables from the controller and measure between the white cable and one of the red cables, don’t measure between both red cables.

4 Most common service works

4.1 Changing of the controller R3

You have to open the two screws at the top of the inner door. After that you can lift out the inner door, but be careful the temperature safety device is inside the door.

Now open the screw behind the white plastic cover. The plastic cover could be broken after that. Now you have to press like shown picture at the perpendiculars side to bring out the controller housing. Please press only in arrow direction.

Now you can take off the complete housing, be careful, the temperature safety device is connected.

At the rear side of the housing you’ll find two screws, you have to open them to work on the controller. To bring back the controller in starting situation, please fit it together in opposite direction.

4.2 Changing of the fan at FD (E2) chamber

You have to unscrew the two side-walls (1 + 2), the bottom (3) and the rear-wall (4) to reach the fanwheel.

The side-walls are screwed at the topside. Before you could bring out the rear-wall, you have to remove the PT-100 holder.

After this you can see the heating elements and also the fan-wheel

Now you have to open the nut at the front of the fanwheel.

Notice: It is a left-thread. Tool: box wrench size 13

Now it is possible to remove the washer and also the fan-wheel.

State: 01/2002 Created: 06/2002 / Jochen Tussinger

To take out the fan-motor with axis, you have to remove the rear-wall of the chamber.

Tool: Screwdriver (Phillips-Screw)

Now disconnect the connection-wires at the fan, if possible mark them for right connection when you put in the new fan.

To take out the fan-motor with axis, you have to remove the three Phillips-screw at the triangle.

Now it is possible to take out the complete part.

4.3 Calibration Procedure “One Point Calibration”

Press the Buttons and for 5 sec. simultaneously.

After the 5 sec. you’ll see C211 in the display.

Don’t use this configuration for the One Point Calibration. You have to use the configuration C212.

Press the Button to go to configuration C212.

Set the measured value with the Buttons and like displayed on your reference measurement system.

A electronic measuring- and display device for temperature which is traceable to a acknowledged standards/calibration institution (DKD , PTB for Germany) with valid calibration certificate is recommended.

Measuring range for incubators at least 20°C to 100°C Measuring range for warming and drying chambers at least 20°C to 300°C

The sensor probe of the reference instrument placed in the centre of the usable chamber volume should be connected to the device via a thin cable suitable to be laid over the door sealing without causing any leakages.

Normally a “One-Point-Calibration” is enough to get a exact regulation of the chamber. If the customer works at two temperatures which are with a difference of more than 5°C you could do a “Two-PointCalibration” to get a exact regulation.

4.4 Change Display from °C (Celsius) to °F (Fahrenheit)

Press the Button for at least 5 seconds The Display shows „unit“.

Change the setting “C” with the Button into “F”

Attention: The controller changes the value automatically into °F.

Confirm your new setting by pressing the Button

Press the Button 4 times to go back to the normal display

Remember: If you set the chamber to °F, the highest Temperature is 300°F. This corresponds to approx. 148,62°C.

Correlation: 0°C = 31°F 100°C = 212°F

[Value in °F] = 1,81 x [Value in °C] + 31

4.5 Activation or deactivation of 0.1 steps at the temperature display.

At the controller R3 it is possible to activate or deactivate the 0.1 step at the display. At BD chambers which could heat up to 100°C the function is activated. At ED and FD chambers the function is deactivated. Please note that the 0.1 steps is only displayed up to

99.9 °C, at 100°C the 0.1 step is deactivated automatically.

Step 1 – Deactivation of the Level-Protection

To access the parameter level you have to unlock the Level-Protection.

You have to press the Button and for at least 10 seconds simultaneously

Now you’ve reached the menu “Code” Press the Button to set the value “001” to “000”

To confirm your setting press the Button to go back to the normal display

Press the Button for at least 5 seconds again so that “C111” will be displayed

Press the Button for 1 time to set the “0” to “1” Confirm your setting by pressing the Button

Press the Button 18 times to go back to normal display. The displayed value now is with 0.1 step

Please restore the Level-Protection. If not it is possible that the parameters could changed. The chamber doesn’t work correctly.
