1) Separate the engine control cables or power cables from the VLW602 connection cables.
2) Remove the caps from the cable glands and open the cover by unscrewing the screws.
3) Lead the cables into the transmitter through the cable glands.
4) Close the cap and tighten the cable glands
5.2 RECOMMENDATIONS FOR EXTERNAL MOUNTING
To avoid the humidity infiltration inside the housing is recommended:
- For electrical connections, tighten the PG9 cable gland..
- fully tighten the cap.
- position the cable so that it forms a downward curve at the PG9 output; in this way the condensation and/or
rain water will tend to drop from the curve bottom.
- The two central cable glands are arranged for the PTU sensor connection cables.

VLW602 - configuration and calibration
6-CONFIGURATION AND CALIBRATION
Via the VLW602 the operator can: access any transmitter function, change configuration parameter settings and other
functions.
6.1 VLW602 FEATURES
The VLW602 program module has 4 buttons which allow to perform all operational, control and programming
instrument functions.
In the configuration menus, is possible:
1.
Submenus and parameters access; press
2.
Parameter options choice: Press
Press
3.
to select and press
to select the option and press
to access.
to store the option.
to exit without storing.
Configure the parameter values; in some parameters the configuration is done by setting a value
(eg., in the SET DISTANCE 4mA parameter is possible to change the the corresponding distance value, in mm):
press
to select the digit to be modified (the digit is highlighted in inverse ),
press
to change the high lighted digits number, press
Press
to exit without storing.
to save the set value and exit automatically.

8.8.5 - F_ WINDOW
Position the cursor on F_WINDOW, press ENTER to access.
It is the increase value (in cm), step to step, of the window width during the
echo signal research phase.
The “F_WINDOW” is the area where the echo reception is active.
Normally it is positioned around the real echo signal and all echoes
detected within the F_WINDOW are deemed valid.
Example: F_WINDOW parameter set to 5.
- The PTU5_ detects an echo signal which is 4 meters from the sensor.
- Suddenly, the echo signal disappears and a new echo signal to 3.5 mt
away from the sensor is detected.
- Each time the echo signal will be emitted, the PTU5_ will enlarge
“F_WINDOW” with 5cm step, until covering the new eco detected area.
Now the F_WINDOW will start to tighten around the new echo signal and
the new measurement of 3,5mt distance will be used to calculate the level
measurement, alarm thresholds, etc..
F_WINDOW serves to filter false echo signals products, for example, by the
agitator blades
