In case of an installation where cabling is outdoors, it must be installed inside a
cable ducting system with IP4X protection degree classified as "cable ducting with
access cover that can only be opened with a tool" according to UNE-EN 50.085-1:
Cable trunking systems and cabling ducting systems for electrical installations-
Part 1: General requirements.
START UP
Operating modes (see Fig.2)
MF1: Relay + Modbus (reading) – [SW1-3=OFF]
Adjustable relay via P1 potentiometer. Factory settings: 1200 ppm / 70%HR
MF2: 0-10Vdc output analogue signal + Modbus (reading) – [SW1=ON, SW2-3=OFF]
0-10Vdc output analogue signal adjustable via P1 potentiometer. Factory set-
tings: 1200 ppm / 70%HR
MF3: 2-10Vdc output analogue signal + Modbus (reading) – [SW1-2=ON, SW3=OFF]
2-10Vdc output analogue signal adjustable via P1 potentiometer. Factory set-
tings: 1200 ppm / 70%HR
MF4: Modbus control – [SW1-3=ON]
Access to reading, edition and communication of working parameters via Mod-
bus communication protocol (see Table 1, Modbus registers). Relay and output
analogue signal enabled. Factory settings: 1200 ppm / 70%HR
Note: If other switch combination is chosen, LED diffuser is switched off and
digital/ analogue signals are inoperative. Microswitches SW5-6 must remain OFF
for correct operation.
On electronic board there are three LEDs (see Fig.1) with the following functions.

LED diffuser
The device displays a real-time concentration level. In operation mode 1, the illu-
mination is two-color while in modes 2, 3 and 4 this is three-color. Light intensity
is adjustable via P2 potentiometer (see Fig.1) from OFF to 100%.
Relay + Modbus (reading) – [SW1-3=OFF]
Green: Value below set point.
Red: Value above set point.
