1 Chamber Description
1.1 BD (E2)
The BD (E2) chamber was developed for microbiology. The chamber is equipped with a R3 controller and
as an Option available with a RS422 Interface. The highest achievable temperature is 100°C.
The BD (E2) Chamber is available in the sizes 53, 115, 240, 400 and 720.
1.2 ED (E2)
The ED (E2) chamber was developed for drying and hot air sterilizing with natural convection. The
chamber is equipped with a R3 controller and as an Option available with RS422 Interface. The highest
achievable temperature is 300°C.
The ED (E2) Chamber is available in the sizes 53, 115, 240, 400 and 720.
1.3 FD (E2)
The FD (E2) chambers was developed for drying and hot air sterilizing with forced convection. The
chamber is equipped with a R3 controller and as an Option available with RS422 Interface. The highest
achievable temperature is 300°C.
The FD (E2) Chamber is available in the sizes 53, 115, 240, 400 and 720.

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.
2.2 Flow Chart of the Heating System of a BD (E2) (Standard BD 115 (E2))
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.

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.
