Converting the HCU
If you have ordered the base adapter without HCU(s) you will have to convert the HCU(s). Proceed as
follows:
► Repeat this procedure for the second HCU, if necessary (for Twin only).
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following instruc
-
tions:
► Loosen the screws (2) fastening the board.
► In addition, the board is fastened with the topmost of
both HCU screws (1). You also need to loosen this.
► Carefully pull the board down and off.
Make sure that the head adapter board is connected
to the head interface via a press-fit connection from
below.
► Loosen the two screws fastening the HCU on the
back of the board and carefully pull the HCU off the
base adapter.
CAUTION!
Washers and pins
Make sure that you do not lose the washers. Make a note
of the number of washers used for each screw, as this
may well differ. These will need to be fitted back in again
as well.
Make sure that you do not damage the pins under the
HCU.
CAUTION
Installation instructions
► Check the firmware and perform a download, if needed (see Service Manual).
