KS 90-1 / KS 92-1 15 Error list / Maintenance manager
Error status Description Behaviour
0 No error
3 Output is blocked Check the drive for blockage

Error
status
Description Behaviour
0 No error
3 Faulty control
action
Re-configure controller (inverse i direct)
4 No response of
process variable
The control loop is perhaps not closed: check sensor,
connections and process
5 Low reversal point Increase ( ADA.H) max. output limiting Y.Hi or decrease (
ADA.C) min. output limiting Y.Lo
6 Danger of exceeded
set-point (parameter
determined)
If necessary, increase (inverse) or reduce (direct) set-point
7 Output step change
too small (dy > 5%)
Increase ( ADA.H) max. output limiting Y.Hi or reduce (
ADA.C) min. output limiting Y.Lo
8 Set-point reserve too
small
Acknowledgment of this error message leads to switch-over to
automatic mode.If self-tuning shall be continued,
increase set-point (invers), reduce set-point (direct)
or decrease set-point range
