FlexLoader Standard Safety Center and connected systems are master
WARNING
This operating mode should be avoided because there can be small residual
risks in the communication between the masters.
If possible, select a system where only FlexLoader Standard Safety Center is
master.
FlexLoader Standard Safety Center transmits emergency stop via a two-channel,
potential free signal to other systems. The emergency stop is transmitted as long
as the safety center emergency stop button is pressed), the emergency stop signal
then returns to its normal operating mode again.
FlexLoader Standard Safety Center is responsible for resetting its own emergency
stop.
Other masters transmit the emergency stop via a two-channel, potential free signal
to the FlexLoader Standard Safety Center. Emergency stop for further masters in
the system is transmitted by signalling a 2 second emergency stop. This is to avoid
locking modes in the emergency stop circuits.
In a system with several masters, each master is responsible for resetting its own
emergency stop circuit.
