Master fault descriptions
If we encounter a problem when it's in use, we can first observe the large LED on the module of the Balluff master:
US:
- Green means the input voltage is normal
- Red flashes means the input voltage <18v
UA:
- Green means the output voltage is normal
- Red means the output voltage <118
- Red also means the output voltage <11V
SF:
- No light means no error
- Red Indicates watchdog timeout channel, general or advanced diagnosis exists or system error,
- Red flashing indicates that the service DCP signal is started via the bus
BF:
- No light indicates no error
- Red indicates slow physical link speed; or no physical contact
- Red blinking means no data exchange or configuration
100:
- No light means communication rate: 10Mbit / s
- Yellow means communication rate: 100Mbit / s
LK:
- Green means data exchange
The second is the Port status display:
Standard port:
- Off indicates that the input or output pin status is 0
- yellow is the input or output pin status is 1
- two flashing red LEDs indicate the sensor power supply is short-circuited or
the red pin 2/4 is short-circuited to pin 3 or there is no high signal at the diagnostic input.
IO-LINK port status:
- Green indicates that the IO-Link communication connection is activated,
- Green flashing indicates that there is no IO-Link product connection or wrong IO-LINK device,
- Green rapid flashing indicates that during data management, IO-Link pre-operation,
- Red rapid flashing means failed verification / IO-Link data length configuration error, data management failure / data management device error,
- Red means IO-Link short circuit, pin 4 to pin 3.
