Start Button Loop 4
The start button loop consists of 6 contacts and they are switched in parallel mode.
If 1 ore more start button is pressed, the contact is closed and the 24 V signal sets an input on
CAN I/O module in section 4 and shows, that any start button is pressed.

4.2.8.3 How does the emergency stop loop work?
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:
4
– All four component change-over tables must be docked.
– All covers must be closed.
– Both emergency stop push-buttons must be released.
– The minimum air pressure must be present.
– The software enable signal must be ready.
– The Message ’
Security Loop OK’ must be sent (for GND on X6 on SSK, CAN I/O output)
– 24 V must be present at the start button.
After the start button is pressed, the SSK combinaton activates the following voltages
: _ 4
– secundary circuit 250 V for servo X/Y axis (via K2, K3, K4).
– secundary circuit 150 V for star axis.
– servo unit receives ’Servo Enable’ signal for servo amplifier (K4.5)
– The message
’Ctrl_On’ must be sent to CAN I/O (24V from axis unit after receiving the
’servo enable)
– 34 V operating voltage for the transport handling.
– 24 V operating voltage for the tape cutter.
– M_X/Y: +24 V for K3 and K4
– M_tape cutter: +24 V for K2

4.2.9 The Safety Combination (K6 Relay)
Legend
1. power for transport 34 VDC from T2
2. power 24 VDC input from power supply DC/DC converter.
3. input from emergency stop loop (24 VDC)
4. message ready to SLIO (SSK is fine).
5. software release (24 VDC when start button pressed and SW release signal is given).
6. GND for SSK (X6), from Message ’security loop OK’
7. start button pressed (24 VDC form start button).
8. M_X/Y: 24 VDC from SSK (power for K3 and K4).
9. power for transport 34 VDC from SSK
10. M_tape cutter: 24 VDC for contactor K2 and power for tape cutter (24 VDC)
About SSK K6 4
Contactor K6 is an industry standard safety combination contactor. Internally it consists of 3 relays
which are configured in a complex fashion to give maximum protection in a fail safe mode. Unfor-
tunately, for ease of understanding, these internal relays are labeled K1', K2' & K3'. The status of
the contactor is indicated by LEDs labeled as H1, H2 and H3.
When the contactor is in an energized state internal relays K2' and K3' are energized, relay K1' is
de-energized. This status closes the contacts 13 and 14, 23 and 24, 33 and 34.
IWhen this status is achieved K6 can be said to be ‚ON' and the 3 LEDs H1, H2 and H3 are all lit.
