Turning the power to the IMD on
Ensure that all connections to the IMD are made.
1. Switch the supply to X1.MAINS on
2. If there is a separate supply to X7.24V switch it on (can also be turned on at the same time as
Mains supply)
3. Switch the supply to X1.SAFE ENERGY on

Updating Firmware
There are two ways to update the firmware (FW) of the IMD:
1.
Update through the “Service” USB connector:
mainly used in production, service and lab.
2.
Update through CANopen:
mainly used in cases when updating remotely, thus eliminating the
need for physical presence in the hub.
When updating through the Service USB connector, an internal bootloader initiated by setting the CAN
ID switch to 15 and restarting the IMD is used to load the new firmware.
When updating through CANopen, a special bootloader must be loaded first through the Service
connector (one time only), and is initiated when needed by a CANopen command.
Using CANopen update method requires development and implementation (by the customer) of
update SW in the Pitch Motion C
ontroller or the turbine’s Main Controller.
It is also possible to load both CANopen bootloader and FW through the Service USB connector (the
IMD is then prepared for FW update through CANopen in the future).
The full FW package contains different files which are used depending on the update method chosen
(the bootloader will typically be released in a separated release package):

•
IMD.out
Only FW application is installed. Internal built-
in bootloader is used for the installation.
Programming mode (built-in bootloader) is
initiated by setting CAN ID to 15 and
restarting the IMD.
NOTE If the
IMD.out
file is installed after
the CANopen bootloader is installed,
the bootloader will be erased and
overwritten.

CoU_IMD.crc
In the first time, the bootloader
(
IMD_Bootloader.out
) is installed through
the “Service” USB connector, followed by FW
application (
CoU_IMD.crc
) installation
through CANopen. In later updates only the
Attention
If the safe energy was disconnected from the SE terminals, the mains supply must be
turned on before the safe energy is turned on.
