The
metal test bullet
should have the smallest detectable diameter. To perform
the test, the bullet is sent together with the material through the metal separator
to check, whether metal is signalised.
•
The test schedule defines when and by whom the metal separator has to be
checked. Example: one hour after the beginning of each shift, the shift electrician
has to check the metal separator using a test bullet. The test result should
logged, indicating date, time and signature. Example: Test bullet 1.5 mm Fe,
detected, 24.08.96, 8:30 hrs, signed (name).

Defective ring coils or electronics can only be performed by the manufacturer.
The ring coil is completely coated with synthetic resin, and it is produced and
tested in a very complicated process. Subsequently, the coil is connected to the
electronics. After that, a function test over several days is performed. Only if all
tests were passed successfully, the units are approved and despatched. Hence,
repair on spot is impossible. After prior agreement, we will of course provide you
with a reserve unit for the repair period.
