Manual – Fieldbus Interface INTERBUS UFI11A

List of Errors

91 System error None Please check the red SYS-FLT LED

on the UFI11A. If this LED is on,

then one or more stations on the

SBus could not be addressed within

the timeout delay. If the red SYS-

FLT LED is flashing, then the

UFI11A itself is in error status. In

this instance, error 91 alone was

transmitted to the control via the

fieldbus.

Check the voltage supply and the

SBus cabling, check the SBus ter-

minating resistors. Check the con-

figuration if the UFI11A was

configured with the PC. Switch the

UFI11A off and on again. Check

the error code using the diagnostic

interface if the error remains, and

take the action described in this

table.

cation stopped
