Supply Voltages
The power supply unit provides the following supply voltages:
▪ 200 V for the servo amplifier of the X and Y axes in the axis unit
▪ 100 V- / 4 V- for the servo amplifier of the star in the axis unit
▪ 30 V for the servo amplifier of the Z and DP axes in the axis unit
▪ 52 V- for the DC/DC converter in the distributor of sector 1
▪ 40 V for the changeover tables and the PCB handling system
▪ 8 V for the changeover tables
▪ 3 x 230 VAC for the lifting table motors of the single or dual conveyor (option)
▪ 230 VAC for the UPS for the station computer and monitors

Position of Protective Contactor Combination and Service Socket
Protective contactor combination 3TK2825
The protective contactor combination is contained in the power supply unit. It is used to monitor the
EMERGENCY STOP circuits and safety equipment.
There are three conditions that must be fulfilled in order to activate the protective contactor combination:
▪ The "software enable" signal must have been sent.
▪ The EMERGENCY STOP loop must be closed.
▪ The start button must have been pressed.
The front side of the protective contactor combination has three green LEDs for displaying the opera-
tional mode:
▪ The "Power" LED indicates that voltage is present.
▪ The "Channel 1" and "Channel 2" LEDs light up if the start button has been pressed, the EMERGEN-
CY STOP loop is closed and the signaling circuit is not signaling a fault status.

Service socket
The service socket is located in the power supply unit and is protected by the cover. It can only be used
if the placement system is connected to the main power supply via a 5-wire connection (L1, L2, L3, N,
and PE). If a 4-wire connection is used, e.g. without N, the socket cannot be used.
EMERGENCY STOP Loop and Signaling Circuit
Structure of the EMERGENCY STOP loop
The following contacts are connected in series and form the EMERGENCY STOP loop:
▪ normally open (NO) contacts for the four protective cover switches
▪ normally open (NO) contacts in the two protective switches for the cover flaps over the PCB convey-
or
▪ Normally open (NO) contacts for the two EMERGENCY STOP buttons
▪ normally open (NO) contacts for the four component trolleys
▪ normally open (NO) contacts for the four flaps over the push-buttons for raising the CO tables
▪ channels 2 and 3 of the protective contactor combination K1
If the EMERGENCY STOP loop is closed, 24 VDC is present at channels 2 and 3 of the PCC. The two
green LEDs for channels 2 and 3 light up in addition to the green Power ON LED.
Structure of the signaling circuit
The six signaling contacts for the covers are connected in parallel and form the "cover signal" circuit. If
one or more covers are opened, the contacts close, and the 24 V signal reaches the CAN bus and sig-
nals that one of the covers is open.
DANGER
Observe the safety instructions for lethal voltages, even when the machine is switched off.
