5.1.1 Elektronic EDR 2000
The electronic module controls all of the appliance's functions.
All of the control elements for the electrical function components are
to be found on this module.
The electronic system is responsible for executing the running of the
various programs and options. This is carried out in connection with
the evaluation of various input signals (temperature, residual moisture,
etc.).
This electronic system is specially configured ex works for each
dryer model via the PNC. It is imperative that the corresponding
spare parts numbers with the specific electronic data are taken from
the spare parts list for the corresponding model.
A key set on an light conductor unit serves as an optical and
mechanical interface with the operator.
The movements of the keys are momentarily transmitted to the keys
which are mounted on the electronic PCB. Corresponding LEDs
transmit light signals to the surface of the control panel by means
of the light conductor.
An additional display is mounted on the EDR 2000 in the form of an
additional display PCB wit LEDs and a 7-segment light conductor
head room are mounted on the light conductor unit.

It is possible that the keyboard layout can differ depending on the equipping of the
appliance. The key set is completely supplied with the keys as a spare part.
However, should it be the case that the keys are to be individually configured, care
is to be taken with regard to the correct positions of the individual keys. Due to
the convex covers, these are adapted and cannot be exchanged for each other.
The key caps have a number inside them (refer to the illustration), which serves
the correct positioning. The position schema is the same for all key sets (refer to
the example below).
