Star Frame
The mechanical E/D transformer (1) consists of a stationary and a rotating part. The 6 sliding contacts
transmit direct voltage (24V/4A), ground and the CAN bus signals (CAN high, CAN low).

The star consists of the star frame, on which all 20 DP
drives are located, the motherboard and the E/D
transformer.
This complete unit is fixed to the motor shaft with three
screws and can be removed for service work after the
raceway has been dismounted.
▪ Above the star you will find the E/D transformer (1) for
supplying energy and data to the DP drives.
▪ The motherboard is located behind the control boards
(2) of the DP drives (3) and is responsible for
controlling and positioning the DP drives.
▪ The control board is plugged into the motherboard.
and is fixed via the two brackets (4).
▪ Two screws fix the complete DP drive unit from
inside, to the star frame.
▪ An index screw (5) ensures that the ED transformer
is correctly positioned during assembly.

Comparison - E/D transformer
▪ The new E/D transformer consists of a stationary and
a rotating part.
The three sliding contacts (5) transmit the direct
current voltage (24V/4A).
▪ Communication, in other words the transmission of
CAN Bus signals, is contactless.
▪ Connector (1) (connection to intermediate distributor)
▪ The centering pin (2) fixes the stationary part (4) in
place.
▪ The rotating part (3) is fixed with five screws to the
star carrier. These can be loosened via the service
opening (6).
E/D transformer – energy transmission
▪ Two transmission leads are needed to transmit the
energy supply:
P24V (1) and GND (2).
▪ Another lead (sliding contact) connects the rotating
part and the housing ground (ESD protection (3)).

Holding Circuit
Holding Circuit
Venturi block
▪ The venturi block consists of 20 small venturi nozzles
is located behind the silencer.
▪ Each venturi nozzle supplies one segment with
vacuum in the hold circuit.
▪ If a segment is in the pickup/placement circuit, the
holding circuit vacuum is increased (for pickup) or
eliminated via air blast (for placement).
