BASE Engineering External Safety Barrier 

The external safety barrier has 2 LED indicators and they are labeled as POWER and ACTIVITY. 

 

POWER LED is solid Blue when the system is ON, otherwise it is OFF. 

 

Activity LED: 

o

 

If no remote host (e.g. BASE Receiver Module) is connected to Barrier, Activity LED is OFF. 

o

 

If a remote host (e.g. BASE Receiver Module) is connected to Barrier (to communicate to a 

PC3 Receiver or an OBC, connect serial port to compatible RS485 port): 

 

Activity LED blinks in Blue color when the system has normal communication 

between Digital Dial and PC3 Receiver or OBC. 

 

Activity LED blinks in Red color indicates that the PC3 Receiver or OBC is 

communicating on the line, however the Dial may not have responded.
