-40- Adjustment
Operating level 1
Detection level
Unless agreed otherwise, the detection threshold of the metal detector is factory preset to an optimum value.
The factory presets represent the best possible compromise between the maximum achievable detection
accuracy and the least possible susceptibility to interference. The data sheet sensitivities are achieved with
detection level settings of between 20 and 10. Adjust the setting until your reference metal part, which you
want to detect with the system, causes a signal deflection that lies above the trigger level. During subsequent
operation, metal parts of the same size and larger will be separated out – but not smaller ones. If you do not
have a suitable metal part, you can obtain standardised test bodies from the manufacturer.
Please note!
The lower the
detection level is set, the higher the detection sensitivity will be, but the susceptibility to
false triggering will also be higher
In order to optimise the detection threshold setting you should proceed as follows:
1) Convey a metal part that should only just be detected. (Standardised test bodies can be obtained
from the manufacturer)
2a) Metal detection
Raise the detection level in small steps until the metal part is not quite detected any longer, then reduce the
detection level setting by a safety margin of 10%.
2b) No metal detection
Lower the detection level in small steps until the metal part is only just detected, then reduce the detection
level setting by a further safety margin of 10%.
Choose product
You can choose between all parameter sets stored under Product memory . The product list can be sorted
according to product number (1-9) or product name (A-Z).

Batch number
A charge text can be entered and the charge can be started or ended here. For example, different customer
orders can be recorded separately from one another in reports via the batch number.

Reject counter
The menu item Reject counter shows the number of metal messages issued by your metal detection device.
On operating level 2 the metal counter can be restored to zero.
