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)

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. 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.
How is SSK K6 energized?
If the safety covers are closed, the emergency stop circuit intact and K5 closed, 24 V is supplied
to terminal X1, X3 and X4, when GND is given on contact 6 (X6) from Message ’security loop OK’
and when a start button is pressed. This voltage allows K1' to be energized and when it's contacts
close then K2' and K3' can energize. As soon as these relays energize, K1' is de-nergized how-
ever K2' and K3' now remain energized due to their contacts providing a self latching facility.
Pressing the ON Button
Assuming any ON button is pressed: 24 V will travel and will split into 2 path.
– 1st path: It will travel to the CAN I/O module 1. The signal from this module will travel from
the CAN bus to notify the Machine Controller that ON button is pressed; this should disable
the Press Start Key message.
– 2nd path: It will travel to the power supply main distributor X16_2, from here, this signal (On
Button) will travel to K1.4 (closed when main switch On), K2.4 (NC), K3.4 (NC), K4.4 (NC),
K5 (NO) and stop at pin 6 of SSK.
The 24 V will only travel when the following conditions are met:
4
When the machine controller gets the signal (1st path) ’START BUTTON pressed’, it will
through the CAN I/O module set an output and proceed to A1 of contactor K5 to energize
K5 (C_Software_On)
4
So when K5 is energized, the signal from 2nd path will flow to X4 of the SSK. 4
