Instruction and Maintenance Rules for:

Float level indicator CLR20

CLR20-1, CLR20-2, CLR20-3, CLR20-C/1, CLR20-C/2, CLR20-C/3

STANDARD FEATURES

The CLR20 is a sensor for the detection of level thresholds on any type of liquid.

The operating principle is based on a permanent magnet (encapsulated inside the

oat) and frictionless reed contacts.

Signal output: SPST (alternatively, NO or NC contact), up to 3 intervention points);

MAX switch power*: 80 VA

MAX switch voltage*: 250V AC/DC

MAX switch current*: 1.3 A

* all indications are for resistive loads only

Cable size: 2x1mm (AWG17) / 150°C / L=600 mm

Connection to process: G 3/8 BSPP

Process temperature: -10 ... +70 °C

MAX pressure: 15 bar

Materials: ow EN1.4571 (AISI 316Ti), body EN1.4401 (AISI 316)

Mounting type: internal, vertically ±30° / horizontally for the curved version

Minimum uid density: 0,7 Kg/dm

Length: from 85 to 2000 mm

SAFETY RULES

All the operations described in this documentation must be carried out only by qualied personnel, authorized by the plant manager,

applying the appropriate safety precautions to reduce risk of re, electric shock or injury.

Operational safety of the appliance is only guaranteed if used in compliance with regulations, in accordance with the instructions for use

and any additional instructions. Arbitrary transformations or modications are strictly prohibited. In case of improper use, the appliance

can be a source of dangers associated with the specic application, or damage to the plant, following incorrect assembly or adjustment.

Check that the power supply system complies with the regulations, with built-in automatic protection switch.

Any inspection, cleaning, maintenance, change or replacement of parts must be carried out with the indicator unpowered and plug

disconnected from the power supply.

INSTALLATION

Before installation, carry out a visual check of the equipment to make sure

that it has not suffered any damage during transport or storage.

If the control reveals anomalies, the product must be sent to the manufacturer

to restore efciency.

The CLR20 indicator must be installed inside the tank, in a vertical position (A)

with a maximum error of ± 30 degrees, or in a horizontal position (C) for the

curved version only. Make sure that there are no external magnetic elds that

could alter the operation of the reed.

ELECTRICAL CONNECTION

Disconnect the power supply before proceeding with the electrical

connection of the device. For voltages above 50V, make sure that the

indicator is grounded correctly. In the case of tanks of insulating material,

always connect the indicator body to the ground with a suitable eyelet (* not

supplied) screwed under the external nut.

Also available in version with M12 connector (for voltages up to MAX 150V).

OPERATION

The rising level of a liquid causes the oat to rise, which runs vertically guided

by the body of the indicator. When the permanent magnet, encapsulated in the

oat, comes in the proximity of the reed contact, it causes it to close by

switching the state of the signal circuit.

The indicator does not require external power sources. To reverse the

operating mode, remove the stop ring at the end and reverse the oat.

The indication stamped on the sphere towards the threaded end indicates the

operating mode: NC = closed circuit in the absence of liquid; NO = open

circuit in the absence of liquid.

MAINTENANCE

Periodically check that there are no solid deposits (e.g. limescale) on the central rod of the indicator body that could obstruct the

movement of the oat. The electrical components inside the indicator do not require any maintenance.
