2. Cortocircuitare per un breve attimo il jumper J4;
3. Rimpostare l'indirizzo desiderato di SW1 e SW2;

The purpose of this guide is to describe the minimum operations required for quick confi guration and setup of the
DPWL refrigerant gas sensor supplied with 24 Vac transformer. Perform the confi guration operations shown in the list
marked  (those marked – should be skipped) under the "Type of confi guration required" column, depending on the
controller used or type of connection. For further information see instruction sheet +050003510 or technical manual

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 confi gured 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 fl ashes (confi r-
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:
ppm (set point desiderato) x 5V
V =
(TP1-TP3)
max valore fondo scala ppm
= 2,5 V
max. full scale ppm value: Semiconduttore = 1000; Infrared = 10000.
It is possible change the threshold alarm by supervisor or modbus parameter.
