5. 

 Customise the factory settings to the desired ones: 

5.1 

 To select the analog output mode, use SW1 switch. (See 

Fig. 5

 

Analog 

output selection switch.

)

 

Select switch position 1 for 0—10 VDC mode of the analog output.

 

Select switch position 2 for 0—20 mA mode of the analog output.

 

Select switch position 3 for PWM (open collector).

5.2 

 То select the sensor range, use the jumpers indicated with 1, 2 and 3. (See 

Fig. 6

 

Sensor range selection jumpers 

and the enclosed information.)

5.3 

 Select the desired response time using the relevant jumpers (see 

Fig. 7

 

Response time selection jumpers

). Use the enclosed information.

6. 

Close the enclosure and fix the cover. 

7. 

Connect the nozzles with the tubing.

8. 

Switch on the power supply.

ATTENTION

If a G‑type article is using the same AC power supply source (transformer) as 
F‑type article, a SHORT CIRCUIT may result when the power supply and analog 
signal terminals are connected to the same common ground! In this case always 
connect different article types to separate AC transformers or use the same 
article version.

NOTE

For sensor calibration and Modbus register reset procedures refer to section
