Configurable functions
This section describes the functions of the Bulkscan® which can be selected via SOPAS
ET software.
4.1
Setting the belt speed
In order to measure the flow, it is essential to determine the speed at which the bulk is
moving on the conveyor belt.
There are several ways to transmit/transfer the belt speed to the Bulkscan®.
•
Set a fixed and known belt speed.
• Connect an encoder to the Bulkscan®.
• Connect a current signal via the analog module BAM100 (see "12.2 Accessories“ on
• Transmit the belt speed via telegram (see "13.1 Telegram reference“ on page 99).
The Bulkscan® can monitor the belt speed and signal on a digital output if the control
range is left.
How to set a fixed value for the belt speed:
Switch to the
Measurement
tab.
Set
Fixed value
as the source as in the
Belt speed
group.
Configure a value for the
Fixed belt speed
.
If necessary, you can use a
Status signal
with the required
Logic
for the belt opera-
tion (see "4.12 Digital inputs“ on page 25).
How to set an encoder:
Switch to the
Measurement
tab.
Set
Encoder
as the source in the
Belt speed
group.
Configure the Resolution of the encoder. This is calculated from the circumference of
the measuring wheel (shaft) and the number of lines.
Measuring wheel circumference in mm
Resolution =
Number of lines
If necessary, you can configure
Direction
detection (positive and negative flow) via
phase or level. (only for Bulkscan® LMS511)
How to set an analog value for the belt speed:
Switch to the
Measurement
tab.
Set
Analog value
as the source in the
Belt speed
group.
Configure the
4 mA point
as well as the
20 mA point
with the associated belt
speeds.
How to configure the belt speed signaling on a digital output:
Switch to the
Measurement
tab.
Configure the
Belt speed
as
Encoder
or as
Analog value
.
Switch to the Interfaces tab
Click on
Digital outputs
to open the
Digital outputs
tab (see "4.13 Digital outputs“
Select the assignment
Belt speed
for the required output.
Select the required
Logic
.
Define the
Lower limit
, the
Upper
limit and the associated
Hysteresis
.
