4. SETTING UP THE MACHINE
The detector and reject system (if fitted) should now be completely installed. The aim
of this section is to describe how to set up the detector for a particular product,
including automatic setting of detection parameters and calibration of timers for
accurate rejection.
For more detailed explanation of the software, please consult the ‘Using The
Software’ section of this manual. If problems are encountered during setup, read the
troubleshooting section of the manual.
4.1 Detector Display and Keypad
Switch on the detector, but not the conveyor (if fitted). The display should look similar
to that shown below.

TEST SETUP
Figure 1 : VFD Detector display and keypad
The display has two lines of 20 characters, and after power on or reset, the top line
shows the current product name and the bottom line shows a "bargraph". The
bargraph can be used to see how good a product setup is, the circles show the size
of signal being detected, the more circles the larger the signal. Solid circles indicate
that metal has been detected. Hollow circles indicate product effect or metal
contamination that is not large enough to trigger the metal detector. If many hollow
circles are displayed each time a product passes then the detector may be at risk
from false triggering. When no signal is detected two circles will be displayed on the
bargraph to indicate that the detector is actively looking for metal.
The keypad has three keys, labelled from left to right: SELECT, , . If at any time it
is required to reset the unit, all three buttons on the keypad should be pressed
simultaneously. This causes the unit to reset as though it has just been switched on.
