5-5- INSTALLATION
5.1 PRECAUTIONS FOR INSTALLATION
5.1.1 CORRECT INSTALLATION
Correct installation of RSL200 sensors to control a Max. level (“a” and “c”) and Min. level (b).
To avoid triggering problems, follow the instructions below:
- Install away from loading zones and keep a minimum distance of 300mm from the walls of the tank.
- When placing the order, select the option for the extension length, allowing the sensitive element to be
positioned at least 200 mm from the bottom of the tank.

5.1.2 Incorrect installation
Incorrect installation of RSL200 sensors.
• do not install near loading zones (c); false alarm signals may be generated and the RSL200 sensors may be
damaged by the pouring in of the material.
• do not install at the centre of the tank loading point (d); the RSL200 sensors and/or ceiling of the tank may be
damaged and eventually break the RSL200 sensor, due to the elevated mechanical stress created in this point.
• do not install in points where accumulations of product may form (e); the RSL200 sensors might remain blocked
in the ‘product present’ position: false max. level alarm or, vice versa, failed min. level alarm signal.

5.1.3 Semiflex Extension
Bent extension (h) (g)
The extension must be straightened (i) to prevent the sensitive element from touching the wall of the tank and
sending a false ‘product present’ signal: false max. level alarm or, vice versa, failed min. level alarm signal.

6-ELECTRICAL CONNECTION
6.1 CONNECTIONS
1) Before energizing this product, make sure all connections have been correctly made and that the mains voltage
corresponds to that on the rating plate.
2) Tighten the cable glands and cover to ensure a protection rating of IP67.
3) To prevent the infiltration of water or humidity, which may damage the level sensor, do not remove the caps
of unused cable glands.
6.2 INFILTRATIONS OF HUMIDITY
To avoid infiltrations of humidity inside the cover, we recommend:
- Using a cable with an external diameter of 6÷12mm for the electrical connections and fully tightening the M20
cable gland
- Fully tighten the cover
- Position the cable in such a way as to form a downward curve in the output of the M20 cable gland;
in this way condensation and/or rainwater will tend to drip from the bottom of the curve.

RSL200 - local operator interface (LOI) - VL601
7-LOCAL OPERATOR INTERFACE (LOI) - VL601
The RSL200 vibration level checks are programmed and calibrated using the VL601 display module
7.1 VL601 FEATURES
The VL601 programming module can be activated and deactivated on-board the RSL200 without affecting the
unit’s operation.
The VL601 module is equipped with an LCD dot-matrix display and allows simple and fast start-up using the 4
programming keys.
The symbol
ON
on the display indicates that the relay is energized, normal condition.
The symbol
OFF
on the display indicates that the relay is de-energized, alarm condition.
1. From “RUN” mode: press to select the parameter to be programmed.
2. Press to confirm the selection.
3. To select the parameter option press .
4. Press to confirm and save the selection, press to exit without saving.
LEFT-HAND ARROW key:
• Exit without saving
• When pressed with the ENTER key
performs a void calibration
UP ARROW key:
• Parameter option selection
SCROLL key:
• Scroll parameters
ENTER key:
• Confirm parameter selection
• Save parameter setting
By unscrewing the cover, it is possible to lock the VL601 module (by turning it clockwise until it clicks) or unlock it
(by turning it anti-clockwise) as shown in the figure.

8-PARAMETER PROGRAMMING
8.1 TH
Press ENTER to modify the programming.
Using the UP ARROW adjust the limit from 0 to 1000:
during programming a “transparent” cursor will be displayed, which indicates
the new positioning of the level alarm limit. Press ENTER to confirm.
NOTE: the TH value must always be less than the value shown in void conditions.
TH: 0350
DELAY: 00 S
MODE: MAX
ŹON
850
In the case of “light” products that tend not to completely block the vibrating forks,
it may be necessary to set the TH value close to the free vibration value.
TH: 0700
DELAY: 00 S
MODE: MAX
ŹON
850
8.2 DELAY
Press ENTER to modify the programming.
Using the UP ARROW, adjust the delay time from 0 to 30 seconds for the
switching of the sensor from the normal state to the alarm state
(for MAX alarm, relay de-energized in the presence of product;
for MIN alarm, relay de-energized in the absence of product).
When the process ceases to be in alarm conditions, the sensor
instantly switches without a delay, from the alarm state to the normal state
(for MAX alarm, relay energized in absence of product; for MIN alarm, relay
energized in presence of product).
TH: 0350
DELAY: 00 S
MODE: MAX
ŹON
8.3 MODE
Press ENTER to modify the programming. Set the sensor alarm mode.
Use the UP ARROW to change the alarm mode, MAX or MIN,
highlighted in negative.
Press ENTER to confirm.
TH: 0350
DELAY: 00 S
MODE: MAX
