3.9.5 Transit
speed
The individual
BS
for each type of product is stored to memory and can be successively modified during the final
verifications with the product, performed in operative conditions.
3.9.5.1 Application with Control Power Box
These transit speed parameters set the speed of the product as it passes through the Detection
Probe. These values are used to define the ejection cycle.

Where an encoder is present (KE>0) this parameter is not available.
On systems with
conveyor belt
, it is recommended to use an encoder for the correct synchronization
of the ejector with the movement of the belt.
On
free-falling applications
, check that BS is set to a value equal or not lower than the expected
product transit speed at the Probe entrance, in order to guarantee an optimal detection and ejection
response from the System.
On applications with
discontinuous transport
(i.e. pumping of the product in a duct), set BS the
speed with active transport and consider the Metal Detector synchronization with the product
transport device (see Timings and Following Conveyor enabling).
Set
BL
and
BM
values as close as possible to
BS
, according to the specified settings, as this can increase the Metal
Detector immunity to interference.
3.9.5.2 Application with Conveyor Control System
These transit speed parameters set the speed of the conveyor belt. These values are used to
regulate conveyor movements and to define the ejection cycle.

Where an encoder is present (KE>0) this parameter is not available.
By modifying the value of
KT
, the parameters
BL
and
BM
are automatically set to nominal values, respectively
30 x KT
and
60 x KT
. BL and BM can also be modified manually. The value set on BS can be successively modified also through
the proper keys on Conveyor Control System panel.
In presence of an encoder, the parameter
BS
is always available, but the ejection cycle is determined according to the
speed measured by the encoder itself (see Timings).
Set
BL
and
BM
values as close as possible to
BS
, according to the specified settings, as this can increase the Metal
Detector immunity to interference.
