2.4.3 Safety and Signaling Circuit
2.4.3.1 Safety Circuit Function
The following conditions must be fulfilled in order to start and operate the placement machine:
All four component trolleys must be docked in and connected.
All protective covers must be closed.
The two 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 V to the Start buttons and the protective contactor
combination.
If one of the Start buttons is now pressed, the protective contactor combination SSK K6 will switch
and activate the following components:
– 250 VDC intermediate circuit voltage for the servo amplifiers for the gantry axes
– 145 VDC intermediate circuit voltage for the star axes
– The axis unit receives a "servo enable" signal for the servo amplifier
– 48 V for X tables (34 V for S tables, not for X4I) – operating voltage is switched through to
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.
