3.2.2 Voltages in the power supply unit after switching on at the main switch
When the main switch is switched on, the following voltages are generated and may or may not
be switched through to the modules: 3
3.3 Control unit
When the main switch is switched on, the DC/DC converters in the control unit are supplied with
52 VDC by the power supply unit. The following voltages are then generated in the control unit:3
+ 5 VDC to supply the digital electronic circuits 3
± 12 VDC to supply the digital electronic circuits 3
± 15 VDC to supply the analogue electronic circuits 3
+ 24 VDC to supply the control circuits, relays, etc. 3
The measuring points are shown in the block diagram "HS-60 control unit, front view, 00334808-
XXXXXXTD3"of the detailed circuit diagrams. 3

3.4 Main distribution unit
Once the placement system has been switched on, the following voltages can be tapped at the
terminal strip for the main distribution unit (see block diagram "Main distribution unit, 00336154-
XXXXXXTD3 of the detailed circuit diagrams): 3
Stabilized voltages 3
5 VDC, ± 12 VDC, ± 15 VDC, 24 VDC 3
Non-stabilized voltages 3

3.5 Servo unit
When the main switch is switched on, the servo unit is supplied with the following voltages: 3
The test sockets are shown in the block diagram "HS-60 servo unit, front view, 00334810-
XXXXXXTD3, page 1" of the detailed circuit diagrams. 3
The ± 15 VDC supply voltages for the servo unit’s electronic circuits are generated from the ± 15 V
supply integrated in the servo unit and can be tapped at the measuring points of the power supply
unit (see HS-60 servo unit, front view, 00334810-XXXXXXTD3, page 2 of the detailed circuit dia-
grams). 3
Measuring point Measured against X1 - 0 V
X4 0 VDC for the servo amplifiers of the x/y axes
X3 4 VDC for the servo amplifiers of the star axis
X2 30 VDC for the servo amplifiers of the z and dp axes

3.6 Description of the power supply functions
The placement system cannot be used in placement mode until all the supply voltages have been
enabled by the protective circuit. The following conditions must also be fulfilled: 3
– All four component change-over tables must be docked.
– All covers must be closed.
– Both emergency stop push-buttons must be released.
– All four component flaps over the component tables must be closed.
– The software enable signal must have been sent.
The enable signal is then sent to contactor SZ4 in the power supply unit via port 2 (X2dm) of CAN
input/output module 1 in sector 4 of the distribution board (see block diagram "Distribution board,
sector 4, 00336153-XXXXXXTD3 in the detailed circuit diagrams). 3

Contactor SZ4 switches 24 VDC to 3
– L+ on the combined contactor/protective device SSK
– the Start button at X4 of the SSK and
– the emergency stop loop at X3 and X5 on the SSK.
If 24 V is present at L+ on the SSK, the green "Power" LED on the SSK will light up. The message
"M ready" is returned to the computer via port 1 (X1dm) of the CAN input/output module 1 in sector
4 of the distribution board. If the safety loop is closed (covers closed, emergency stop button not
pressed), 24 V is sent to terminals X3 and X5 on the SSK. 3
