Learn Messages
The table below lists the messages that may appear during a Learn process and provides some
guidance.
Message Explanation
+Use ferrite+
This only applies when performing a ferrite tune
and indicates that either the
ferrite wand is not being passed through the machine or that there is
insufficient ferrite material in the wand. Check that the wand being used is the
one supplied with the machine.
+Head overload+
The message indicates that the gain cannot be reduced any further to stop the
head overloading. Possible reasons for this could be:
The sample pack being used contains a large contaminant.
A product not specified for use with the machine is being used.
The product packaging is highly conductive.
If in doubt, contact your local Loma Service Centre.
+Working dry+
This message indicates that the product has so little moisture that it produces
no product signal. The detector will automatically set the Working Mode to
DRY.
+Bad pack+
This message indicates that the product signal being received exceeds the
Max Threshold option value set in the Menus > Learn > Set Up menu.
This could be because the sample pack being used contains a contaminant or
the Max Threshold option value has been set too low.
Check that the sample packs being used are representative of production
packs. For example, if a frozen product is being learnt are the sample packs
still frozen?
If in doubt, contact your local Loma Service Centre.
+Adjusting+
The head is reducing the Gain and/or Frequency settings to account for the
product effect of the product.
+Head locked+ The head is using the Head Gain value entered in the Menus > Learn >
Setup menu rather than determining the value itself as the Head Gain option
has been set to LOCKED.
+Mode locked+ The head is using the Working Mode value entered in the Menus > Learn >
Setup menu rather than determining the value itself as the Working Mode
option has been set to LOCKED.
+Dry product+
The product has little or no product signal and therefore the wrong Working
Mode option may have been locked in the Menus > Learn > Setup menu.
+Learn
complete+
The Full Learn process has been completed successfully.
