2.5.4.2 Structure of the signalling circuit
The six signaling contacts for the covers are connected in parallel and form the "cover signal" cir-
cuit. If one or more covers are opened, the contacts close, and the 24 V signal reaches the CAN
bus and signals that one of the covers is open.
The two signaling contacts for the EMERGENCY STOP buttons are connected in parallel and form
the "emergency stop push-button signal circuit". When an EMERGENCY-STOP button is pressed,
a 24 V signal is sent to the CAN bus and signals that one of the EMERGENCY-STOP buttons has
been pressed.
The four signalling contacts for the push-button flaps are connected in parallel. They form the
"Flap signal" circuit. If one or more flaps is raised, a 24 V signal is applied to the CAN bus and
signals that one of the cover flaps is not closed.
The four signalling contacts for the CO trolleys are connected in series and form the "Component
table" signal loop. If a CO trolley is missing, a 0 V signal is sent to the CAN bus. If all trolleys are
connected, the signal is approximately 16 V.
2.5.4.3 Description of the functions of the safety circuit
The following conditions must be fulfilled before the placement system can be started or operated:
– all four component trolleys must be docked in and connected.
– all covers - four over the gantries, one over the PCB input belt and one over the output belt -
must be closed.
– both EMERGENCY-STOP buttons must be released.
– all four flaps over the push-buttons for raising and lowering the CO trolley must be closed.
– the minimum operating pressure must have been reached.
– the software Enable signal must have been given, thus activating the safety circuit.
– The power supply must be sending 24 V to the start buttons and the protective contactor com-
bination.
– If one of the start buttons is now pressed, the protective contactor combination PCC will switch
and activate the following components:
– 200 V link voltage for the servo amplifiers for the gantry axes
– 100 V link voltage for the star axes
– Operating voltage for the lifting table motors
– the servo unit will receive a "Servo Enable" signal for the servo amplifier.
– 34 V operating voltage is switched to the CO trolleys
– 24 V operating voltage is switched to the used tape cutters.
The machine is then ready for use.

2.5.5 Guard on the component table locations
DANGER 2
All locations must be equipped with feeders in order to guarantee operational reliability. If there
are not enough feeders available, a guard ("dummy feeder") must be fitted in place of the feeder.
