Power LED
PWR Green: Supply voltage
Off and the status LED on the module is green: Defective
coupler
Have coupler repaired or replaced
The internal fuse was triggered due to an overload
Off and the status LED on the module is off: Improper supply
voltage
Check the supply voltage
Collective error
SF Red: Conguration error, or error in the coupler, or error in a
module, or there is a new diagnostic message
Redashing: Station in Force mode
Check that the ESI conguration le is up-to-date
Check if the congured station setup matches the actual
setup
Read the diagnostic message with the web server or an
engineering tool and determine which further actions to take
Bus failure
BF Red: No connection to the eldbus Check the eldbus cable and the PLC conguration
Redashing: Conguration error, no connection to the
control unit, or error in the parameter set
Check the eldbus parameters and the PLC conguration
Check that the ESI conguration le is up-to-date
Check if the congured station setup matches the actual
setup
Maintenance
MT Yellow: Error on the system bus or eldbus Check that the modules have been snapped into place
properly
Connection/active
L/AIN Off: No connection Check the eldbus cable
Green: Connection established between port 1 of the
coupler and another eld device
Greenashing: Data being exchanged on port 1
Connection/active
L/A OUT Off: No connection Check the eldbus cable
Green: Connection established between port 2 of the
coupler and another eld device
Greenashing: Data being exchanged on port 2
Coupler state
RUN Off: Coupler in INIT state
Greenashing: Coupler in PRE-OPERATIONAL state
Green lights up briey: Coupler in SAFE OPERATIONAL
state
Green: Coupler in OPERATIONAL state
Internal error
ERROR Red: Critical error in the coupler
Red lights up briey: Error in the coupler application
Red lights up brieytwice: Output of the sync manager
watchdog out-of-date
Redashing: Conguration error
Check that the ESI le is up-to-date. Check if the congured
station setup matches the actual setup
Check that the coupler rmware is up-to-date. Compare the
master cycle time with the time set up on watchdog timer
Input supply voltage
3.1 Green: Supply voltage for input current path >18VDC
3.2 Red: Supply voltage for input current path <18VDC Check the supply voltage
3.4 Red: Internal fuse defective Replace the coupler
Output supply voltage
4.1 Green: Supply voltage for output current path >18VDC
4.2 Red: Supply voltage for output current path <18VDC Check the supply voltage
4.4 Red: Internal fuse defective Replace the coupler
