Safety rules
Programming is only to be carried out by qualified personnel.
High voltage on the printed circuit board.
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.
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.

Description
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 Control PCB.
Selecta Control PCB
The PCB Module is located under the top cover on the front of the machine, 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.
