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 persons.
-Keep the work zone clean and orderly. Accidents are more likely to occur in untidy areas and environments.
-Before beginning work, make sure that the motion detector is in a 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 and replacements must be carried
out with the motion detector 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 motion detector.
-Make sure that the electricity system complies with the laws in force. Make sure that the earthing is efficiently
connected when the instrument is installed. Check to be sure that the power socket is suitable, that it complies
-The motion detector must never be stopped by detaching the plug from the power socket. Moreover, 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 extensions cables of the permitted
-Do not allow children oe unauthorized persons to touch the cable when the instrument is plugged in.
Before proceeding with the installation operations,
Operating temperature: from -15 to +70 °C
Field of use: 30 - 6000 pulses/minute
visually inspect SMD 20/P in order to be sure that
it has not been damaged during transport or
the storage period. If this check reveals anything
irregular, the motion detector must be sent to
CAMLOGIC Snc to be restored to efficiency.
The constructional characteristics of the unit that
detections the motions can be installed so that
the cable input is turned at 90° intervals, allowing the power cable to be fixed
in the most favourable position ( Fig.1 ).
Installation can be done in two ways: by radial signal reading ( Fig.2 ) or by
off-centre in-line reading ( Fig.3 ). Whatever the method sensor head must not be
more than 10 mm. from actuator revolving surface. Sensor axis must be at the middle
line of actuator side surface for a radial read out. If signal reading is axial, sensor axis
must coincide with insert mid-point as show in the " REFERENCE FIGURES ".
CAMLOGIC inductive motion detectors can be
installed in any position.

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 power supply and signal carrying cable.
By the terminal box there is the wiring plate ( Fig.4 ) which has printed on it the
wiring diagram for the power supply and use of the inductive motion detector.
CAUTION: There is a screw in the terminal board compartment which is used for
the earthing of the motion detector. This screw must be connected to the yellow-green
conductor ( only green for the USA ) of the power cable. The ground connection of the
inductive motion detector, through the yellow-green conductor is compulsory.
before powering up. For connections to the terminal boards use fork cable terminals; for the ground connection use
an eyelet cable terminal.
After having been powered, the inductive motion detector starts by lighting the led and energizing the relay for ten
seconds. This allow the controlled machine to reach operating rate and to keep the relay energized if the number
of revolutions to check has been correctly entered. The relay switch contact is commutated ( led on ) for detected
revolutions of the value entered ( Set-point ) on the selectors ( Fig.4 ) or higher. If the revolutions are less than the
Set-point, the relay is relased with contact commutation to the hold position and led off. The detected number of
revolutions is updated every two seconds, corresponding to the maximum energizing delay time of the relay when the
Set-point is reached. When the revolutions drop below the entered value, the relay de-energizing delay is two seconds
setting the number on digital setting should be
multiplied by 10. For example if the outside right
switch is set on 1 this means motion detection of
10 Rpm. This motion detector can be used for a
speed range from 10 to 2000 Rpm ( referred to the
survey of 3 impulses per round ). Though higher
speed setting are possible, the functional performance
of the device is not guaranteed at higher rates.
CAMLOGIC inductive motion detector need no
routine maintenance.
Possible extraordinary maintenance is restricted
to replacing parts that are deteriorated by use.
CAMLOGIC Snc, 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 motion detector, or from bad handling by
the operator and faulty installation. Warranty is
moreover forfeit if non-genuine spare parts have
