2.6.4.2 Structure of the signaling circuit
The signaling contacts in the protective switches of protective covers, of cover flaps over the PCB
conveyor, of component trolleys and of EMERGENCY STOP buttons are polled individually. All
the signaling contacts are closed when the machine is on standby. If a protective cover, for exam-
ple, is raised, the associated signaling contact opens. This change of state is signaled to the con-
trol computer via the CAN bus. An error message to this effect appears on the user interface.
2.6.4.3 Description of the functions of the EMERGENCY STOP loops
The following conditions must be fulfilled in order to start and operate the machine:
– All four component trolleys must be docked in and connected.
– All protective covers must be closed.
– Both cover flaps over the PCB conveyor must be closed.
– Both EMERGENCY STOP buttons must be released.
– The cover flaps (option) over the feeder modules must be closed.
– The minimum operating pressure must have been reached.
– The "software enable" signal must be active. This ensures that the safety circuit is closed.
– The power supply must be sending 24 VDC to the start buttons and the protective contactor
combination.
– If one of the start buttons is now pressed, the protective contactor combination PCC K6 will
switch and activate the following components:
– 250 VDC link voltage for the servo amplifiers for the gantry axes
– 145 VDC link voltage for the star axes
– The axis unit receives a "Servo enable" signal for the servo amplifiers
– 34 VDC operating voltage is switched to the component trolleys.
– 24 VDC operating voltage is switched to the used tape cutters.
– The PCB conveyor control receives the enable signal for the PCB clamping, the PCB
stopper and the lifting table control.
The machine is then ready for use.

2.6.5 Hand guard at the component trolley locations
WARNING 2
All locations must be equipped with feeder modules in order to guarantee operational reliability. If
there are not enough feeder modules available, unassigned locations should be fitted with a
hand guard (dummy feeder module). When a waffle-pack holder is set up, the remaining loca-
tions have to be protected again with a hand guard.
