LED STATUS INDICATORS
Sender and receiver units consist of an optical part (lenses) and a LED
indicator panel. The LEDs on the sender and receiver units indicate the
operating status of the AOPD as shown below:
SENDER
LED
Test
Yellow
when intrusion simulation is active
Off
when there is no intrusion simulation
Alignment
Steady orange
when the lowest beam is not aligned
Quick blinking orange
when the lowest beam is aligned
Slow blinking orange
when at least 6 beams are aligned
Off
when screen is fully aligned
Power
Green
when power is ON
RECEIVER
LED
OSSD2
Green
when OSSD2 is ON
Red
when OSSD2 is OFF
OSSD1
Green
when OSSD1 is ON
Red
when OSSD1 is OFF
Power
Green
when power is ON
TEST MODE SELECTION (YBB)
The YBB sender unit is equipped with a test mode function controlled
through the voltage supply on the test input. Enabling the test mode
stops the light beams, simulating an intrusion into the protective field.
Note that, as Type 2 protective devices, YBBs are self-testing. How-
ever, the test input may be useful for system setup, to ensure that the
machine control circuit operates properly or, to determine the actual
response time of the overall safety setup. Table 5 below shows the test
functions triggered by the pin connections on the sender unit.
