sensore rilevatore perdite gas refrigerante / refrigerant gas

Cod. +050003515 - rel. 1.4 - 29.09.2015
DPWL*: sensore rilevatore perdite gas refrigerante / refrigerant gas leak sensor
The purpose of this guide is to describe the minimum operations required for quick configuration and setup of the
DPWL refrigerant gas sensor supplied with 24 Vac transformer. Perform the configuration operations shown in the list
marked  (those marked – should be skipped) under the “Type of configuration required” column, depending on the
controller used or type of connection. For further information see instruction sheet +050003510 or technical manual
+0300035EN.
La presente guida ha lo scopo di fornire le operazioni minime da eseguire per una veloce configurazione e messa in
funzione del sensore rivelatore di gas refrigerante DPWL alimentato con trasformatore 24Vac. Eseguire la configurazione delle operazioni riportate nell’elenco contraddistinte dal segno  (quelle evidenziate con il segno – non sono
da fare) seguendo la colonna del “tipo di configurazione da eseguire” in accordo al controllo o tipo di collegamento.
Per maggiori informazioni consultare il foglio istruzioni +050003510 o manuale tecnico +0300035EN.

Usato con controllo IR33 Universale il valore espresso a display in ppm per la versione semiconduttore è x 10, per la
versione infrared x100; È possibile alimentare in DC anche prelevando l’alimentazione da pRACK dai terminali +VTerm e
GND (J24) In questo caso DPWL - J1 non presente, J2 presente; J7 – J8 – J9 – J10 si configurano solo se si desidera l’uscita in
tensione (vedi manuale tecnico).

Note:

When used with the IR33 Universal controller the value on the display in ppm for the semiconductor version is x 10, for the
infrared version is x100; DC power is also available from the pRack via the +VTerm and GND (J24) terminals. In this case,
DPWL - J1 is not present, J2 is present; J7 – J8 – J9 – J10 are only configured for voltage output (see the technical manual).
