Interface for Compact Flash Card
The IndraControl L40 is provided with a slot for a Compact Flash card.
This slot can be used to insert the memory card containing the firmware
(card to be ordered separately). In addition, data and programs are stored
to this card. Operation without Flash card is not possible.
DANGER
Operation without memory card causes
uncontrolled movements!
⇒
Be sure not to remove the Compact Flash card as
long as the IndraControl L40 is in operation.
