ALARM INFEED – IN-CONVEYOR HAS AUTOMATICALLY REVERSED 2 TIMES BUT
IS STILL UNABLE TO RUN
Follow the instructions on the screen:
Inspection of the in-conveyor is needed. Problem can be caused by food
waste material getting stuck in the in-conveyor. Clean the infeed
hopper and the in-conveyor. If necessary run the in-conveyor in reverse
and thereby loosen any material that is stuck inside the pipe leading to
the cylinder. Once the blockage has been cleared the infeed can be
used again without reseting any fuse/inverter.
Note that this ALARM needs to be acknowledged in the ALARM list in order to turn off the Alarm
Indicator which is visible in the left hand upper corner on all screens.
Use the ALARM button to go to alarm log menu.
From this alarm screen, it is possible to navigate to the
‘manual run infeed’ screen pressing the symbol with
the infeed and two arrows on the alarm screens.
Use the back and forward arrow trying to loosen the
blockage in the inconveyor.
Note that the lid of the infeed hopper must be closed – the infeed auger does not work otherwise!
This is the most common alarm text when there is a blockage in the in-conveyor. The function reverses the
in-convey when something gets stuck and makes two more attempts of feeding the food waste into the
cylinder before giving the alarm.
This alarm text is connected to the parameter Threshold Current and defines threshold current in [%]
relative to rated motor current to be used in comparisons of the set threshold current. The parameter Delay
time current defines delay time prior to activation of current comparison. More information can be found in
‘Machine specification’ and in the Inverter manual. The function of the in-conveyor motor trying to reverse
two times if something gets stuck before sending an alarm can be adjusted in ‘tools’ menu.
The frequency inverter setting is set using this menu. These parameters may need adjusting to the quality
of the food waste material if the inverter gives this alarm when nothing is actually blocking the in-conveyor
or only gives this alarm when the blockage is too tight. The screen shows the actual curren reading in % and
the following parameters can be adjusted:
-
Threshold current limit in % = this setting gives the current in (%)
relative to actual motor current
-
Delay time current = defines delay time prior to acitavtion of
comparision of threshold current and rated motor current.
-
Run time reverse = time for infeeder to run in reverese.
The values set at delivery can be found in ‘Machine Specification.’
If adjustments are necessary – contact your distributor for advice before proceeding.
If the infeed hopper, propellers and in-conveyor have been cleared and the alarm comes back
contact service personnel.
