YELLOW GREEN BLUE BROWN RED
-mA +mA 4-20mA A(RS485) B(RS485)
5.1 CONNECTIONS
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 VLW602FEATURES
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 to select and press to access.
2. Parameter options choice: Press to select the option and press to store the option.
Press to exit without storing.
3. 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 to save the set value and exit automatically.
Press to exit without storing.

7.3 - ECHO MAP
Pressing LEFT ARROW, from RUN mode, to access directly to the echoes digital map display, which are in
PTU50-51-56 receiving.
This function is useful for:
- properly orient the transducer pointing.
- verify the echoes in acquisition correctness.
- identify any false echo signals that may cause measurement errors.

The rectangle placed at the echo line base,
indicates the measurement range within which the
echo signal in reception is considered always valid for
the distance measurement. This interval value is varia-
ble depending on the measurement conditions: min. ±
2.5% of the measured distance.
