Verifying the value defined for the blanking
zone
When the value for the height measurement presents an incorrect and continuous reading,
it may be indicating that the blanking zone parameter is not correctly set up.
Prerequisites
The TV80 has been set up with its hardware units connected as specified by the relevant
installation instructions.
Context
Whenever you want a catch monitoring sensor to measure height, you must define a
blanking zone.
When the sensor is set up to measure height from the middle of a trawl door, the physical
properties of the door can cause false echoes and hence wrong height information. A
blanking zone is a “blank space” that will make the sensor disregard all echoes received
from objects inside the defined zone.
Procedure
1 Connect the sensor to the computer using the programming cable.
2 On the processor unit desktop, double-click the TV80 icon to start the program.
3 On the
Setup
menu, select
Installation
.
4 In the
Sensor list
, select the sensor you want to check its configuration parameters.
5 Select
Modify Sensor
.
6 In the very first
PX Sensor Configurator
dialog box, select communication port
and sensor type, then select
Connect
.
The relevant sensor
Configurator
dialog box opens.
7 Check the value defined for the blanking zone of the height measurement.
8 If necessary, enter new values based on your knowledge of the physical location of
the sensor and the properties of your gear.
9 Select
Program Sensor
to transfer the chosen parameters to the sensor.
