About SSK K6
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.
How is SSK K6 Energi zed?
5.2.9.2 How is SSK K6 Energized?
If the covers and the emergency STOP circuit are closed and K5 is deactivated, 24 V will be supplied to
terminals X1, X3 and X4, as soon as the GND is present at contact 6 (X6) - a state triggered by the
message Safety loop OK - and the start button has been pressed. This voltage allows K1 to be
energized and when its contacts close, K2 and K3 will energize. As soon as these contacts energize, K1
is de-energized. However K2 and K3 remain energized as their contacts have a self latching facility.
Pressing the ON Button
5.2.9.3 Pressing the ON Button
Assuming the ON button is pressed: 24 V is activated and will split into 2 paths.
▪ 1. : 24V is activated at the CAN I/O module 1. The signal from this module activates the CAN bus to
notify the machine controller that the ON button has been pressed. This deactivates the message
Press Start Key .
▪ 2. : 24V is present at the power supply main distributor X16_2 and, from here, this signal (start
button) is sent to K1.4 (closed when main switch ON), K2.4 (break contact, NC), K3.4 (break contact,
NC), K4.4 (break contact, NC), K5 (make contact, NO), ending at pin 6 of the SSK. The 24 V is
activated when the following conditions are met:
Condition: When the machine controller gets the signal (1st path) START BUTTON pressed , it will set
an output via the CAN I/O module and supply A1 of contactor K5 with 24V (C_Software_On)
So when K5 is energized, the signal from 2nd path will flow to X4 of the SSK.
How Does the Protective C ontacto r Combination (S SK) Latch ?
5.2.9.4 How Does the Protective Contactor Combination (SSK) Latch?
Condition: When K5 is energized, the following will happen:
▪ L+ will get 24 V and will light up the first LED
▪ Since L+ and X1 are internally connected, this 24 V signal will be fed back from X1 to the CAN I/O
module as a SSK READY.

▪ The X4 on SSK will have 24 V temporary (only when ON is pressed), but it is enough to energize K1'
internal of the SSK. When K1’ is energized, K2' and K3' will also be energized internally of SSK -
only if X3 and X5 of SSK has 24 V with them.
How does X3 and X5 of SSK get the 24V?
▪ If all covers are closed, the changeover tables are docked and the STOP button is not pressed, there
will be 24V present at K5 pin 3 and 4 via the emergency STOP circuit and from there at X3 and X5
of the SSK.
24V voltage on the X14 and X34 of the SSK (protective contactor combination)
▪ When K2' and K3' are latched inside the SSK, pin 34 of SSK will have 24 V. Main task of them is to
power the tape cutter and to energize K2. (switching through of U, V, W of X/Y axes)
▪ When K2’ and K3’ are latched inside the SSK, pin 14 of SSK will have 24 V. Main task of it is to
energize K3 and K4 (with a slight delay).
Various Signals
5.2.10 Various Signals
Software Rele ase (Software E nabled)
5.2.10.1 Software Release (Software Enabled)
The software release signal is given by the CAN I/O card when the machine controller software is fully
booted. This means that not only must the machine controller software be booted but communication
must be established to the Vision system, axis boards, CAN BUS, station computer and line computer
(unless it is operating in stand-alone mode). When the start button is pressed, the CAN I/O module
issues the 24V output signal and 24V is present K5, contact A1.
If the emergency STOP circuit is interrupted, the software release will not be issued.
Software release signal
OK Signal Safety Loop
5.2.10.2 OK Signal Safety Loop
The message Safety loop OK will be emitted by the CAN I/O module, if the following conditions have
been fulfilled:
▪ All covers closed
▪ All component tables connected
▪ All emergency STOP buttons released
▪ Emergency STOP circuit closed
The 24 V output from the CAN I/O module is present at the main voltage supply (inrush current limitation
board) and GND is switched through to contact 6.

1. BTS 117: voltage switch for GND
This signal is transmitted to the power supply X8-20 and connects GND to SSK, contact X6.
Control On Signal
5.2.10.3 Control On Signal
If connector K4 of the power supply is enabled, the auxiliary contact K4.5 will close and 24 V (servo
release signal) will be present from the DC/DC converter to the distributor of the main power supply X13,
to the axis unit X21 and to the anti-crash board.
The introduction of the A364 also involved direct software realization of the anti-crash function on the
axis card.
Here it is split in 2 paths:
Path 1: 24 V present as Servo enable signal at the X/Y axis servo board, to enable the servo
amplifier (to switch GND to the servo board via optical coupler).
Path 2: 24 V present as Ctrl_ON signal at sector 2, connector X4qa and ends as M_Ctrl_On at the CAN
I/O module. The 4 main axis is allowed to move now into any position.

Power Distribution
5.2.11 Power Distribution
The power distribution to the different sectors, gantries and heads is highly structured. 5V and 24 V,
generated by DC/DC converter U20 and U30 in main power supply, will first activate at distributor main
power supply, connector X16. Then at section 2, main distributor, connector X2qa and then at the
terminal block X1qa for general use, at connector X71qa and at last at connector X71ra, section 4.
52 V for camera illumination, generated by U7, is activated at main power supply distributor, X18, and
split into two paths.
