ELECTRICAL WIRING

The conductors forming the signal carrying cable connected to the microswitch

( Fig.3 ) must have an adequate cross-section so that the current density,

in each conductor, is no higher than 4 A/mm². One of these is used only

for the earthing of the level gauge.

The cross-section of the conductors must also be adequate in relation to the

length of the cable used to avoid a drop in voltage along the cable over

the values prescribed by the regulations on the subject.

It is likewise reccomended to use flexible cables with an adequate outside

diameter for the fair-leads used ( not supplied ) to ensure a perfect seal of

the cable clamp on the signal carrying cable.

certified ATEX Exd IP65 or IECEx Exd IP65 M16x1.5.

Use Faston cable terminals ( 6.3 x 0.8 mm. ) to connect the microswitch terminals and the ground connection.

CAUTION:

In the terminal board compartment, the connection for Faston type terminal whose position is marked

by the ground symbol on the printed circuit ( Fig.3 ) is used for the earthing the level gauge. The yellow-green

conductor ( green only for the USA ) of the signal carrying cable must be

connected to this terminal. The ground connection of the float level gauge,

through the yellow-green conductor, is compulsory.

On the external level gauge casing side, placed side by side to the cable

inlet, a second connection point is present for the external ground connection

executable with a screw M5 and an eyelet cable terminal.

The external earthing has to be carried out by the installator.

The equipment has to be protected against impact and electrostatic inside

the tank.

The user has to protect the equipment circuits with fuses against short circuit.

The max. surface temperature is without dust and not safety distance.

MAINTENANCE

CAMLOGIC float level gauges for liquids need no

routine maintenance. Take care the external cleaning

of the level gauge, the dust accumulation doesn't

have to exceed a thickness of 5 mm.

WARRANTY

CAMLOGIC S.n.c., in addition to the terms of the

supply contract, guarantees its products for a

period of twenty-four ( 24 ) months from the date

of shipment.

This warranty is expressed only in the repair or

replacement free of charge of parts that, after

careful examination by the Manufacturer, turn out

to be difective.

Warranty, excluding all liability for direct or indirect

damage, is considered to be restricted to only

defects in materials and has no effect if the parts

returned turn out to have been anyhow dismantled,

tampered with or repaired by anyone other than

the Manufacturer.

Warranty likewise excludes damage deriving from

negligence, carelessness, bad or improper use of

the level gauge, or from bad handling by the

operator and faulty installation.

Warranty is moreover forfeit if non-genuine spare

parts have been used. A returned level gauge, even

if under warranty, must be shipped carriage free.
