User manual - PLE500 - 5
1.3 Precautions for safe use
Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse
affects on the performance and functions of the product. Not doing so may occasionally result in
unexpected events. Do not handle the Digital Controller in ways that exceed the ratings.
• The product is designed for indoor use only. Do not use or store the product outdoors or in any of
the following places.
- Places directly subject to heat radiated from heating equipment.
- Places subject to splashing liquid or oil atmosphere.
- Places subject to direct sunlight.
- Places subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas).
- Places subject to intense temperature change.
- Places subject to icing and condensation.
- Places subject to vibration and large shocks.
• Installing two or more controllers in close proximity might lead to increased internal temperature
and this might shorten the life cycle of electronic components. It is strongly recommended to
install cooling fans or other air-conditioning devices inside the control cabinet.
• Always check the terminal names and polarity and be sure to wire properly. Do not wire the
terminals that are not used.
• To avoid inductive noise, keep the controller wiring away from power cables that carry high voltages
or large currents. Also, do not wire power lines together with or parallel to Digital Controller
wiring. Using shielded cables and using separate conduits or ducts is recommended. Attach a
surge suppressor or noise filter to peripheral devices that generate noise (in particular motors,
transformers, solenoids, magnetic coils or other equipment that have an inductance component).
When a noise filter is used at the power supply, first check the voltage or current, and attach the
noise filter as close as possible to the Digital Controller. Allow as much space as possible between
the Digital Controller and devices that generate powerful high frequencies (high-frequency
welders, high-frequency sewing machines, etc.) or surge.
• A switch or circuit breaker must be provided close to device. The switch or circuit breaker must be
within easy reach of the operator, and must be marked as a disconnecting means for the controller.
• Wipe off any dirt from the Digital Controller with a soft dry cloth. Never use thinners, benzine,
alcohol, or any cleaners that contain these or other organic solvents. Deformation or discoloration
may occur.
• The number of non-volatile memory write operations is limited. Therefore, use EEprom write mode
when frequently overwriting data, e.g.: through communications.
1.4 Environmental policy / WEEE
Do not dispose electric tools together with household waste material.
According to European Directive 2012/19/EU on waste electrical and electronic equipment and its
implementation in accordance with national law, electric tools that have reached the end of their life
must be collected separately and returned to an environmentally compatible recycling facility.

4.1 Mounting sequence of the PL500 and of the PLE500
expansion modules
The PL500 with the relevant I/O modules requires mounting and connection via the specific bus
lodged in the hollow of the DIN rail. The I/O modules (series PLE500-xAD) will be automatically
numbered at each power-on, assigning the number 1 to the first I/O module connected to the right
of the PL500, the number 2 to the following one and so on, always moving towards the right side.
The position of the various modules shall thus reflect the sequence set in the LogicLab project in the
definition of the PLCEXP network. For the numbering procedure to work correctly, removing devices
from the network is not allowed by releasing them from their own bus and leaving some empty
modules (slot bus) between one module and the other. All the connection/disconnection operations
must be carried out with power off.
Clik!
Couple all the buses by pushing them towards the DIN
rail, making sure that the male connection faces left
and the female one faces right.
Couple the buses together by sliding them along the
DIN rail.
Insert the various modules in the slots of the buses
starting from the PL500 and continuing to the right
with the I/O modules.

• Distinguish the power supply line from the power lines.
• Avoid the proximity with contactor units, electromagnetic contactors, high power motors and use
filters in any event.
• Avoid the proximity with power units, particularly if with phase control.
• The use of network filters is recommended on the power supply of the machine in which the
instrument will be installed, particular in case of 230 VAC power supply.
The instrument is devised to be assembled with other machines. Therefore, the EC marking of
the instrument does not exempt the manufacturer of the system from the safety and conformity
obligations imposed for the machine as a whole.
• Wiring of pins use crimped tube terminals or flexible/rigid copper wire with diameter 0.25 to 1.5
mm2 (min. AWG28, max. AWG16, operating temperature: min. 70°C). Cable stripping lenght 7 to 8
mm.

18 PLE500 - Manuale d’uso
Warning!
Un malfunzionamento nel controllore digitale può occasionalmente rendere impossibili
le operazioni di controllo o bloccare le uscite di allarme, con conseguenti danni
materiali. Per mantenere la sicurezza, in caso di malfunzionamento, adottare misure di
sicurezza appropriate; ad esempio con l’installazione di un dispositivo di monitoraggio
indipendente e su una linea separata.
1.3 Precauzioni per l’uso sicuro
Assicurarsi di osservare le seguenti precauzioni per evitare errori, malfunzionamenti o effetti negativi
sulle prestazioni e le funzioni del prodotto. In caso contrario, occasionalmente potrebbero verificarsi
eventi imprevisti. Non utilizzare il controller digitale oltre i valori nominali.
• Il prodotto è progettato solo per uso interno. Non utilizzare o conservare il prodotto all’aperto o in
nessuno dei seguenti posti:
- Luoghi direttamente soggetti a calore irradiato da apparecchiature di riscaldamento.
- Luoghi soggetti a spruzzi di liquido o atmosfera di petrolio.
- Luoghi soggetti alla luce solare diretta.
- Luoghi soggetti a polvere o gas corrosivi (in particolare gas di solfuro e gas di ammoniaca).
- Luoghi soggetti a forti sbalzi di temperatura.
- Luoghi soggetti a formazione di ghiaccio e condensa.
- Luoghi soggetti a vibrazioni e forti urti.
• L’utilizzo di due o più controller affiancati o uno sopra l’altro possono causare un incremento di
calore interno che ne riduce il ciclo di vita. In questo caso si raccomanda l’uso di ventole per il
raffreddamento forzato o altri dispositivi di condizionamento della temperatura interno quadro.
• Controllare sempre i nomi dei terminali e la polarità e assicurarsi di effettuare una cablatura corretta.
Non collegare i terminali non utilizzati.
• Per evitare disturbi induttivi, mantenere il cablaggio dello strumento lontano da cavi di
potenza con tensioni o corren ti elevate. Inoltre, non collegare linee di potenza insieme o in
parallelo al cablaggio del controller digitale. Si consiglia l’uso di cavi schermati e condotti
separati. Collegare un limitatore di sovratensione o un filtro antirumore ai dispositivi che
generano rumore (in particolare motori, trasformatori, solenoidi, bobine o altre apparecchia-
ture con componenti induttivi). Quando si utilizzano filtri antidisturbo sull’alimentazione,
controllare tensione e corrente e collegare il filtro il più vicino possibile allo strumento.
Lasciare più spazio possibile tra il controller e dispositivi di potenza che generano alte frequenze
(saldatrici ad alta frequenza, macchine per cucire ad alta frequenza, ecc.) o sovratensioni.
• Un interruttore o un sezionatore deve essere posizionato vicino al regolatore. L’interruttore o il
sezionatore deve essere facilmente raggiungibile dall’operatore e deve essere contrassegnato
come mezzo di disconnessione per il controller.
• Rimuovere lo sporco dallo strumento con un panno morbido e asciutto. Non usare mai diluenti,
benzina, alcool o detergenti che contengano questi o altri solventi organici. Possono verificarsi
deformazioni o scolorimento.
• Il numero di operazioni di scrittura della memoria non volatile è limitato. Tenere conto di questo
quando si utilizza la modalità di scrittura in EEprom ad esempio nella variazione dei dati durante le
comunicazioni seriali.
1.4 Tutela ambientale e smaltimento dei rifiuti / Direttiva
WEEE

4.1 Sequenza di montaggio del PL500 e dei moduli di
espansione PLE500
Il PL500 con i relativi moduli di I/O prevede il montaggio e la connessione tramite apposito bus
alloggiato nell’incavo della barra DIN. I moduli di I/O (serie PLE500-xAD) verranno automaticamente
numerati ad ogni accensione, assegnando il numero 1 al primo modulo I/O collegato alla destra
del PL500, il numero 2 a quello seguente e così via, procedendo sempre verso destra. La posizione
dei vari moduli dovrà quindi rispecchiare la sequenza impostata nel progetto di LogicLab nella
definizione della rete PLCEXP. Perché la procedura di numerazione possa funzionare correttamente,
non è consentito rimuovere dispositivi dalla rete sganciandoli dal proprio bus e lasciando dei moduli
vuoti (slot bus) tra un modulo e l’altro. Tutte le operazioni di connessione /sconnessione devono essere
effettuate in assenza di tensione.
Clik!
Agganciare tutti i bus premendoli verso la barra DIN,
prestando attenzione che la connessione maschio sia a
rivolta verso sinistra e la femmina verso destra.
Agganciare tutti i bus tra loro facendoli scorrere sulla
barra DIN.
Inserire negli slot dei bus i vari moduli, iniziando dal
PL500 e proseguendo verso destra con i moduli di I/O.
