Stop Button Loop
5-17: Stop Button Loop
The stop button loop consists of 6 contacts which are switched in parallel mode. If one or more STOP
buttons has been pressed, the contact will close and 24 V will be present at the input of the CAN I/O
module in sector 4, showing that one of the STOP buttons has been pressed.
Start Button Loop
5-18: Start Button Loop
The start button loop consists of 6 contacts and they are switched in parallel mode. If one or more START
buttons has been pressed, the contact will close and the 24 V will be present at the input of the CAN I/
O module in sector 4, showing that one of the START buttons has been pressed.

5.2.8.3 How Does the Emergency STOP Circuit Function?
The placement system cannot be used in placement mode until all the supply voltages have been
enabled by the protective contactor combination.
The following conditions must also be fulfilled:
All four component changeover tables must be docked.
All covers must be closed.
Both emergency stop buttons must be released.
The minimum air pressure must be present.
The software enable signal must be ready.
The message
Safety 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 pressing the start button, the protective contactor combination releases the following voltages:
Secondary circuit 250 V for servo X/Y axis (via K2, K3, K4).
Secondary circuit 150 V for star axis.
The servo unit receives
the servo release signal
for the servo amplifier (K4.5)
The message
Ctrl_On
must be issued at CAN I/O (24 V from the axis unit after receiving
the servo
release signal
)
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

Legend:
1. Power for transport 34 VDC from T2
2. Power 24 VDC input from power supply DC/DC converter.
3. 24 VDC input from emergency STOP circuit
4. Message
READY
to CAN I/O module (SSK is OK.)
5. Software release (24 VDC when start button pressed and SW release signal is given).
6. GND for SSK (X6), from message
Safety 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)
5.2.9.1 About SSK K6
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. Unfortunately, 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.
When this status is achieved, K6 is "ON" and the 3 LEDs H1, H2 and H3 all shine.
