Note! It is very important
that the board is protected from static electricity
Remember!
• Always use an earthed wrist strap.
• Without the antistatic wrapping the board is unprotected.
• Keep all subjects away from the board which can cause static electricity.
• Subjects like plastic, foam plastic, nylon, or cellophane wrapping
are all big dischargers of static electricity.
• Static electricity can not always be felt, heard or seen.
• Board components can be damaged by static electricity under 100V.
• Static electricity can not be felt, heard or seen till the voltage
reaches 2500V.
IMPORTANT SERVICE NOTE!
Continuity and resistance measurements suggested by the procedures in this
manual require that power to the dryer be disconnected, and that the device
whose resistance is being measured be disconnected from all circuits that might
affect the accuracy of the measurement.
Safety rules
Programming is only to be carried out by qualified personnel.
High voltage on the printed circuit board.

Generel
From factory, the dryer has been set to specific values for:
Time, temperature, cooling, reversing, etc.
The above parameters are changeable by reprogramming the Selecta PCB.
Selecta II PCB
Fig. 1 The PCB Module is located on the back of the operating panel, see the Service
Manual for the specific dryer.
In order to reprogramme the dryer it is necessary to switch the print board into
programming mode.
In programming mode the buttons on the operating panel are used for changing the
parameters. See page later in this section “Switching to service mode”.

There are different types of operating panels.
On the dryer operating panel the buttons might not have any symbols in which case they
are only usable when the dryer is in service mode.
Fig. 1 In service mode the 4 buttons are used for changing the parameters.
Selected temperature
Light emitting diode is lit at the selected temperature or show the default-temperature
setting.
Default temperature can be set in Group A in parameter A 05.
