Star
8.2.7.7 Star
The star consists of the star frame, on which the 12 DP drives are located, the control board (Single Core
Solution), the valve terminal and the E/D transformer.
The holding circuit is in the center of the star.
The complete unit is fixed to the rotor of the star motor.

The star frame plate is fixed directly to the rotor of the star
motor.
The valve terminal and the E/D transformer are fixed to
the back of the star frame.
The twelve DP drives are fixed to the front and the
holding circuit with control unit (SCS) is fixed to the
center.
The vacuum or air blast is fed via the holding circuit
through the star frame plate to the individual DP drives
(through a hose).

Valve term inal
8.2.7.10 Valve terminal
The valve terminal consists of 12 valves (1), one for each segment.
The compressed air from the holding circuit (2) is distributed over 12 channels for the 12 segments. Each
of these channels has a valve. This enables the compressed air to be switched on or off for each
segment (3).
This means, after a component has been placed, the compressed air can be switched off for this
segment.
Before picking up a component, the compressed air is switched on again and vacuum is present at the
nozzle via the holding circuit with venturi nozzles. The disconnection of compressed air after placement
reduces the compressed air per placement head by approx. 40-50%.
The outer channels (4) are used to measure the holding circuit and supply the air blast or vacuum for the
pickup/placement circuit via the pressure control valve.

The SCS has two main tasks:
1. Controlling the DP drives
2. Evaluating the Z down light barrier.
The assembly consists of a carrier plate and two boards
(control module and power module).
The power and data supply is via the head CAN bus from
the intermediate distributor, E/D transformer to the SCS.
The SCS features 12 connectors, which establish the
connection for the power and data supply to the DP
drives.

8.2.7.11 E/D Transformer (for CPP Heads < Version 05)
▪ The energy and data transformer consists of a stationary and a rotating part.
▪ The three sliding contacts transmit the direct current voltage (24V/4A).
▪ Communication (the transmission of CAN Bus signals) is contactless. The transmitter is located on
the rear cover of the CPP head and the receiver module on the valve terminal.
▪ The connector (4) supplies power from the intermediate distributor.
▪ The centering pin fixes the stationary part in place via the rear cover of the CPP head.
▪ The rotating part is fixed with five screws to the valve terminal.
▪ The valve terminal consists of 12 holding circuit
valves, which can be switched independently at any
time and in any star position.
▪ Switching on the valves means “throughput”:
Compressed air is present at the venturi nozzles
(voltage = 0V). If a valve should fail or if it is without a
voltage supply, vacuum is always present at the
holding circuit.
▪ Switching off the valves means “valve closed”: There
is no compressed air present at the venturi nozzle
(24 V voltage is present). This saves compressed air!
