zione 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.

Note: 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).
Cambio del baud rate da 9600 (default) a 19.200
1. Posizionare i commutatori rotativi SW1=F e SW2=F;
2. Cortocircuitare per un breve attimo il jumper J4;
3. Rimpostare l’indirizzo desiderato di SW1 e SW2;
4. Per verificare se è stato cambiato, togliere l’alimentazione e verificare se alla riaccensione il led rosso esegue un lampeg-
gio (conferma dell’avvenuto cambiamento del parametro);
Per cambiare il livello di soglia allarme ppm
1. Collegare il multimetro in volts DC tra TP3 (0V–GND) e TP1 (alarm).
2. Ruotare il trimmer P1 nella scala da 0 a 5Vdc selezionando il valore ( scala lineare). Per il calcolo applicare la seguente formula:
V(TP1-TP3) = ppm (set point desiderato) x 5V
max valore fondo scala ppm
Es. sensore ver. semiconduttore
con set point a 500 ppm V(TP1-TP3) = 500 x 5
1000
= 2,5 V
max valore fondo scala ppm: Semiconduttore = 1000; Infrared = 10000.
Se possibile, cambiare la soglia allarme da supervisore o parametri modbus.

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.

Key to do - not to do
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).
Changing the baud rate from 9600 (default) to 19200
1. Switch rotary selectors SW1=F and SW2=F;
2. Jumper terminal J4 for a brief moment;
3. Reset the desired address on SW1 and SW2;
4. To make sure that the setting has been changed, power down and when restarting check that the red LED flashes (confir-
ming the parameter has been changed);
Changing the alarm threshold in ppm
1. Connect the multimeter with DC voltage setting between TP3 (0V–GND) and TP1 (alarm).
2. Turn trimmer P1 on the scale from 0 to 5 Vdc to select the value (linear scale). For the calculation apply the following formula:
V(TP1-TP3) = ppm (set point desiderato) x 5V
max valore fondo scala ppm
E.g. semiconductor ver. sensor
with set point 500 ppm V(TP1-TP3) = 500 x 5
1000
= 2,5 V
max. full scale ppm value: Semiconduttore = 1000; Infrared = 10000.
It is possible change the threshold alarm by supervisor or modbus parameter.
