HERMA 400 TROUBLESHOOTING
3.28 US (130519) 139/154
11.2.46 SM814 Unwinder failure Power stage
This message appears if there is a control error of the power output stage.
11.2.47 SM825 Loop unwinder failure TEACH process
This message appears if on teaching the unit‘s function an error occurred. This message is unlikely to
occur. Please turn to our Technical Service or to your HERMA partner if this malfunction occurs
repeatedly.
11.2.48 SM827 Loop unwinder failure
This message appears if much more label web was transported than taken from the loop. Maybe
slippage, maybe blocked backing paper. Check the unit.
11.2.49 SM828 Loop unwinder failure Too slow
This message appears if the sensor for maximum loop remained uncovered too long. Possibly the label
web slips, the labeling performance is too high, wrong operating temperature for the unit.
11.2.50 SM829 Loop unwinder failure Circuit voltage too low
This message appears if the operating voltage is too low. Possibly the internal power supply is
defective.
11.2.51 SM830 Loop unwinder failure Overload
This message appears if the unit was overloaded for an extended period of time. Possibly the rotating
disk is rough-running, the labeling performance too high, maybe a double penulum is to be used.
11.2.52 SM831 Loop unwinder failure Temperature too high
This message appears if the unit‘s operating temperature is too high due to an overload.
11.2.53 SM832 Loop unwinder failure End of reel
This message appears if the loop cannot be built up any longer.
11.2.54 SM834 Loop unwinder failure Power stage
This message appears if there is a control error of the power output stage.
11.2.55 SM845 Winder failure TEACH process
This message appears if on teaching the pendulum area an error occurred. The measurement
segment is too small (<90°).
11.2.56 SM848 Winder failure Torn tape / too slow
This message appears if the pendulum remains in its released position too long. A web break or the
rewinder does not reach the required rewinding speed.
