Default
With banding set to OFF the inital operating frequency for all products defaults to the lowest
available of 31kHz. This of course can be changed to whichever frequency it is desired to start
from.
When banding is set then it is recommended to set the default frequency as suggested by the
following:
Aperture dimension in the range of 75 - 150mm - depending upon the band selected, use
l
the 333kHz upwards range.
Aperture dimension in the range of 175 - 200mm - depending upon the band selected, use
l
the 224kHz upwards range.
Aperture dimension in the range of 225 - 300mm - depending upon the band selected, use
l
the 195kHz upwards range.
Aperture dimension in the range of 325 - 550mm - depending upon the band selected, use
l
the 109kHz upwards range.
Any change made to the value after the Head menu is exited will change all product memories
back to the new value selected. Therefore it is advised not to revisit this entry unless necessary.
Ferrite Frequency
The IQ3X uses a product called "Ferrite" to provide a pre-set compensation value that the
detector can recall to use with any product that when learnt exhibits no signals when passed
through the detector aperture. The ferrite frequency is normally set to the same value as the
default frequency.
Irrespective of whether banding is used or not the "Ferrite" product has to be set up using the
"Tune for resistive" clear plastic wand found within the control box area.
Learning the wand is the same as learning a product and can only be done when the Photeye
option in the Menus > Service > Configuration > System menu has been set to NO. Once Ferrite
has been learnt then further access should be denied to prevent accidental use.
To do this, navigate to the Menus > Service > Options menu and set the Access Ferrite option to
NO.
Factory frequency setting for ferrite is selected from the smallest aperture dimension and will be
the same as the default frequency. Therefore, depending upon the band selected, it will be
from the same range listed above. Should there be a change to the set band then the ferrite
memory would have to be re-learnt using a frequency from the new band used.
