SAFETY

Photoelectric proximity sensor
Operating instructions
1 Safety notes
■Read the operating instructions before commissioning.
■Connection, mounting, and setting may only be performed by trained specialists.
■Not a safety component in accordance with the EU Machinery Directive.
■UL: Only for use in applications in accordance with NFPA 79. These devices shall
be protected by a 1 A fuse suitable for 30 V DC. Adapters listed by UL with connec‐
tion cables are available. Enclosure type 1
■When commissioning, protect the device from moisture and contamination.
■These operating instructions contain information required during the life cycle of
the sensor.
2 Correct use
The MultiPulse WTB4-3 is an opto-electronic photoelectric proximity sensor (referred to
as "sensor" in the following) for the optical, non-contact detection of objects. If the pro‐
duct is used for any other purpose or modified in any way, any warranty claim against
SICK AG shall become void.

3 Commissioning
1 Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐
sories).
Note the sensor's maximum permissible tightening torque of 0.8 Nm.
2 The sensors must be connected in a voltage-free state (Uv = 0 V). The information
in the graphics [B] must be observed, depending on the connection type:

Only apply voltage/switch on the power supply (Uv > 0 V) once all electrical connec‐
tions have been established. The green LED indicator lights up on the sensor.
Explanations of the connection diagram (Graphic B):
MultiPulse WTB4-3P (PNP: load -> M)
Output oscillates at 10 Hz if an object is located within the fixed sensing range 30
to 100 mm. Output switches off if an object is located within the range 0 to 30 mm
and > 100 mm.
3 Align the sensor with the object. Select the position so that the red emitted light
beam hits the center of the object. You must ensure that the optical opening (front
screen) of the sensor is completely clear [E]. We recommend making the adjust‐
ments using an object with a low remission.

tion. The fixed sensing range is 30 ... 100 mm.

37 Avvertenze sulla sicurezza
■Prima della messa in funzionamento leggere le istruzioni per l'uso.
■Allacciamento, montaggio e regolazione solo a cura di personale tecnico specializ‐
zato.
■Nessun componente di sicurezza ai sensi della direttiva macchine UE.
■UL: Solo per l'utilizzo in applicazioni ai sensi di NFPA 79. Questi dispositivi devono
essere protetti con fusibile 1 A idoneo per 30 V dc. Sono disponibili adattatori
elencati da UL con cavi di collegamento. Enclosure type 1
■Alla messa in funzionamento proteggere l'apparecchio dall'umidità e dalla sporci‐
zia.
■Queste istruzioni per l'uso contengono le informazioni che sono necessarie
durante il ciclo di vita del sensore fotoelettrico. deTec4 core
38 Uso conforme alle prescrizioni
La MultiPulse WTB4-3 è una fotocellula a riflessione optoelettronica (di seguito nomi‐
nato sensore) utilizzata per il rilevamento ottico senza contatto di oggetti. Se viene uti‐
lizzata diversamente e in caso di modifiche sul prodotto, decade qualsiasi diritto alla
garanzia nei confronti di SICK.

39 Messa in funzione
1 Montare il sensore su un punto di fissaggio adatto (vedi il programma per acces‐
sori SICK).
Rispettare il momento torcente massimo consentito del sensore di 0.8 Nm.
2 Il collegamento dei sensori deve avvenire in assenza di tensione (UV = 0 V). In base
al tipo di collegamento si devono rispettare le informazioni nei grafici [cfr. B]:

Solamente in seguito alla conclusione di tutti i collegamenti elettrici, ripristinare o
accendere l'alimentazione elettrica (UV > 0 V). Sul sensore si accende l'indicatore
LED verde.
Spiegazioni dello schema di collegamento (grafico B):
MultiPulse WTB4-3P (PNP: carico -> M)
L'uscita oscilla a una frequenza di 10 Hz quando un oggetto si trova in un campo di
commutazione compreso tra 30 e 100 mm. L'uscita si disinserisce quando un
oggetto si trova in un campo di scansione compreso tra 0 e 30 mm oppure oltre
100 mm.
3 Orientare il sensore sul rispettivo oggetto. Scegliere la posizione in modo tale che il
raggio di luce rosso emesso colpisca il centro dell'oggetto. Fare attenzione affinché
l'apertura ottica del sensore (finestrella frontale) sia completamente libera [cfr. E].
Si consiglia di effettuare l'impostazione con un oggetto a bassa riflessione.

funzionamento. La distanza di commutazione fissa è 30 ... 100 mm.

Verificare la tensione di ali‐
mentazione e/o il collega‐
mento elettrico /
Check the power supply,
check all electrical connecti‐
ons (cables and plug connecti‐
ons)
Il LED verde non si accende /
Green LED does not light up
Interruzioni di tensione /
Voltage interruptions
Assicurarsi che ci sia un'ali‐
mentazione di tensione sta‐
bile /
Ensure there is a stable power
supply without interruptions
Il LED verde non si accende /
Green LED does not light up
Il sensore è guasto /
Sensor is faulty
Se l'alimentazione di tensione
è regolare, allora chiedere una
sostituzione del sensore /
If the power supply is OK,
replace the sensor
Il LED giallo lampeggia /
Yellow LED flashes
Il sensore è ancora pronto per
il funzionamento, ma le condi‐
zioni di esercizio non sono
ottimali /
Sensor is still ready for opera‐
tion, but the operating conditi‐
ons are not ideal
Controllare le condizioni di
esercizio: Dirigere il raggio di
luce (il punto luminoso) com‐
pletamente sull'oggetto / Puli‐
zia delle superfici ottiche /
Sensibilità / controllare la dis‐
tanza di commutazione e, se
necessario, adattarla, vedi
grafico F. /
Check the operating conditi‐
ons: Fully align the beam of
light (light spot) with the
object. / Clean the optical sur‐
faces . / Readjust the sensiti‐
vity / Check sensing range
and adjust if necessary; see
graphic F.
il LED giallo si accende, nessun
oggetto nella traiettoria del rag‐
gio /
Yellow LED lights up, no object
in the path of the beam
La distanza tra sensore e
sfondo è inferiori alle capacità
di funzionamento /
/ Distance between the sen‐
sor and the background is too
short
Diminuire la distanza di com‐
mutazione, vedi grafico F /
Reduce the sensing range,
see graphic F
L'oggetto è nella traiettoria del
raggio, il LED giallo non si
accende /
Object is in the path of the
beam, yellow LED does not
light up
La distanza tra sensore e
oggetto è troppo grande o la
distanza di commutazione ha
un'impostazione troppo
bassa /
Distance between the sensor
and the object is too long or
sensing range is set too short
Aumentare la distanza di com‐
mutazione, vedi grafico F /
Increase the sensing range,
