Operation - Advanced Detection Systems 1200E Series Installation Manual And Owner's Manual

After plotting, a curve will form. All points inside the curve indicate
settings that allow the detector to overlook any product effect. Points
outside the curve are settings which would result in false detects caused
by the product itself.
The optimum settings are found at the highest sensitivity within the
curve. It should be noted that the more consistent the product, the closer
the settings can be to the lines of the curve. Less consistent products
will cause the curve to move slightly with each product. When this occurs,
the final settings should be well within the curve to prevent false
detects from occurring due to the product differences.
Storing the settings in memory:
Once the optimum phase and sensitivity settings have been determined, they
should be entered using Menus 46-48. Next, a product number of 1-100
should be assigned and stored in memory using Menus 52 and 54.
The settings for up to 100 products can be saved. For reference, a list of
assigned product numbers should be maintained. The settings are saved
permanently unless you choose to change them; loss of power will not
affect product memory.

OPERATION

After product set-up has been completed, the detector is ready for
operation and should have the "Run" menu (#7) on the display. Check that
the product selection shown on the display is correct.
On detection of metal, the reject device, light, and or alarm will
activate after the "delay" time has elapsed. This is caused by the
detector's output relays changing state.
The reject and signal devices will continue to operate until the "operate"
time has elapsed.
Similarly, any auxiliary equipment that has been wired to stop upon
detection will do so after the "delay" time has elapsed. Unlike rejects,
however, the auxiliary equipment usually must be restarted by depressing
the start button on the equipment's motor starter. The equipment will not
start until the metal detector operate time has elapsed. (Refer to "Wiring
for Conveyor Stop"). If the device or equipment does not operate this
way, the outputs may have been turned off via the keypad.
