Capacitive level gauges PFG-06
The PFG-06 level gauge is made in compliance with the regulations in force in the European Union and specifically with:
- Casing in LATIOHM 62-03 PD01 G/20. IP65 protection.
- Electrical construction in compliance with Directive 2013/35/EU on low-voltage electrical material and Directive 2014/30/EU
Envisaged power supplies: 110/220 V. 50/60 Hz - 24/48 V. 50/60 Hz - 24 V.c.c.
-
Use contact capacity: 8 A. a 250 V.c.a.
-
-Operating temperature: from -20 to +70 °C.
Maximum pressure: 1.1 bar.
SAFETY RULES
All the appropriate safety precautions must be taken when electrically operated equipment is used, in order to reduce
the risk of fire outbreaks, electric shock and injuries to people.
- Keep the work zone clean and orderly. Accidents are more likely to occur in untidy areas and environment.
- Before beginning to work make sure that the level gauge is in perfect condition. Damaged or broken parts must be
repaired or replaced by competent personnel authorized by the Manufacturer.
- All verifications, inspections, cleaning and maintenance operations, part changes or replacements must be carried out
with the level gauge disconnected and the plug removed from the power socket.
- It is absolutely forbidden for children, unauthorized and/or inexpert persons to touch or use the level gauge.
- Make sure that the electricity system complies with the laws in force. Make sure that the earthling is efficiently connected
when the instrument is installed. Check to be sure that the power socket is suitable, that it complies with the laws in
- The level gauge must never be stopped by detaching the plug from the power socket. Never use the cable to pull the
plug from the socket.
- Periodically check to be sure that the cable is in a perfect condition and replace it if damage is discovered. This operation
must only be carried out by competent and authorized persons. Only use cables of the permitted type and marked.
- Protect the cable from high temperatures, lubricants and sharp edges. Do not twist or knot the cable. Do not allow
children or unauthorized persons to touch the cable when the instrument is plugged in.
Before proceeding with the installation operations, visually inspect PFG-06 in order to be

OPERATION
Operation of the capacitive level gauge PFG-06 is based on the capacity variation to
which the sensor is subjected by immersion or when near any material, whether this
is or is not a conductor, granular or in powder form.
The sensitivity regulation trimmer (Fig. 1) allow the response of the sensor to be
adapted to the characteristic of the material to be checked. Turn clockwise to increase
and counterclockwise to decrease the sensitivity.
The activation field sensor varies from 0 to 25 mm.
Led 1 and Led 2 on the power and wiring printed circuit board (Fig.1) indicate the
commutation of the output contacts of the relays.
The wiring plate (Fig. 2) placed on the inside of the level gauge lid, shows the position

side or top. It is important to choose the position so that the device is not hit by the falling load, likewise taking care that

of the power connections and the resting position of the relays when not powered.
With power connection and a level of the material lower than the probe position of
PFG-06, there is commutation of the R2 relay contacts, indicated by illumination of Led 2.
When the level of the material raises enough to cover the probe, there is commutation
on both relays contacts. Led 1 lights up indicating the commutation of the R1 relay
contacts, while Led 2 turns off to indicate the de-energizing of R2 relay.

powered and in both cases of product presence or absence.

reveals anything irregular, the PFG-06 must be sent to CAMLogic to be restored to efficiency.

Diameters of 0.5 mm² to 1.5 mm² are sufficient for the connecting cables owing to the low current values applied.
In any case the section must prevent the current density from exceeding 4 A/mm² in each conductor. The cross-section
of the conductors must also be adequate in relation to the lenght of the cable used to avoid a drop in the voltage
along the cable over the values prescribed by the regulations on the subject.

an adequate outside diameter for the cable entries used (not supplied)
signal carrying cable.
CAUTION : In the terminal board compartment, the connection for

Always check that the mains voltage and
frequency correspond to those given on the
plate of the level gauge before powering it.
The power cable must be fixed to the main by
a qualified installer in compliance with the
current safety standards in merit.
For electric connections to the terminal use

CAMLogic, 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 defective.
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.
Moreover, warranty is forfeit if non-genuine spare
parts have been used.
A returned level gauge, even if under warranty,
must be shipped carriage free.
Inside the cover there is the wiring plate (Fig. 2) which has printed on it the wiring diagram for the power supply and
use of the level gauge.
