COMMON PRODUCT RECOGNITION ISSUES
Product Recognition Errors can appear in 2 ways:
1. After initiating cook cycle, the controller displays “PRODUCT NOT RECOGNIZED - NO RECIPE FOUND”.
2. The controller displays the incorrect product for the product that was layed on the grill.
In both cases, the most common reasons for these 2 issues are as follows:
OVERLAPPING
PRODUCT
Overlapping�Product�
-�
Ensure that you do
not have any patties
overlapping when you
lay product. This will
fool the controller into
thinking that there is
much thicker product
on the grill than there
is
Platen�makes�contact�
with�Chicken�Ring�
-
Always make sure that
the chicken ring is clear
of the adjacent platen
prior to initiating a
cook cycle.
Wrinkled�or�Worn�
Teflon�Sheet�-�
Ensure
that the teflon sheet
is installed and/or
wrapped correctly to
platen. A loose, worn,
or teflon sheet with
tears and/or scratches
can effect product
recognition.
Auto�calibation�done�
with�carbon�build�up�
or�product�residue�on�
grill�surface�
- Ensure
that the grill surface
is free of any carbon
build up. Debris on
the grill surface during
auto calbration will
cause the control to
mark the location
of the grill surface
incorrectly.
In any of the cases as outlined above or in any other event, perform an Forced Auto Calibration to reset the upper platen
distance to the grill surface. Prior to performing a Forced Auto Calibration, be sure to:
1. Make sure the upper platen is free and clear of any carbon build up or debris.
2. Ensure that the grill surface is scraped and cleaned.
3. Teflon sheet should not be worn and be fit to the upper platen tightly.
Perform a Forced Auto Calibration routine as indicated in section “PRODUCT RECOGNITION”, “TO PERFORM FORCED AUTO
CALIBRATION”.
