Elements on the field bus coupler BK5200
If an error occurs, the field bus status/operating status LEDs signal the type of
error and where it occurred.
WICHTIG! In some cases, the field bus coupler does not complete the flashing
sequence once the error has been rectified. Restart the field bus coupler by swit-
ching the supply voltage off and on again, or by resetting the software.
