Sensor Module
Electronic Control
There are three separate electronic controls: the motor control module, the sensor
module and the display module.
The motor control module receives
commands from the sensor module for
operating the heat source and controlling the
motor’s speed and direction.
The sensor module has overall control of the
dryer. It controls the lid lock and drum door
actuator, as well as measuring the dampness of
the clothes via the sensor bars.
An optically isolated serial communications port
links the motor control and the sensor module.
The third electrical communication is the display
module. It is the interface that passes user
settings to the sensor module and displays
information in the form of LEDs and text on the
display screen.
EPROM: The EPROM stores cycle and history data in the Sensor Module. This data is
used for diagnosing dryer faults. It’s like the black box recorder that planes have, its
permanent memory.
There is a special tool used for servicing the dryer – Smart-Tool. This device can be used
to receive this EPROM information to help servicing.
There are three things EPROM stores:
1) It records cycle and history data.
2) Stores the serial number, model number, time of manufacture etc for servicing.
3) Saves critical parameters when the power fails, so when the power is restored it can
carry on the cycle.
