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.

RSL200 - installation

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.

DELAY: 00 S

MODE: MAX
