5.2.2  Operation with Fieldbus (RS485) 

The  flow  control  driver  can  be  operated  with  the  fieldbus  interface,  which  is  an 

RS485

  with  Modbus  RTU 

protocol. Contact 

Levitronix

®

 Technical Department

 (see 

Section 8

) for detailed protocol specifications. The 

RS485  interface  can  be  used  in  connection  with  the  USB  interface  of  a  PC  and  the 

Levitronix

®

  Service 

Software

. Various accessory cables are available to connect to the 

RS485

 of the drivers as illustrated in 

Figure 

5

 for the 

EasyConnect

 model and 

Figure 7

 for the 

OEM 

model. 

5.2.3  Operation with User Panel LUI-B.1 

The RS485 interface can also be used with the user panel 

LUI-B.1

, which has the same menu functions as 

the 

Stand-Alone

 model (described in 

Section 5.1

). The relevant configurations are illustrated in 

Figure 7

 for 

the 

OEM

 and in 

Figure 5

 for the 

EasyConnect

 driver models. 

5.3  Zero Adjustment of Flow Sensor 

5.3.1  Stand-Alone Model 

Zero adjustment of the flow sensor can be done manually in the system menu functions as described in 

Section 

5.1.2

. It is important to prepare the flow sensor as described in 

Section 4.8

 and to assure that the hydraulic 

circuit is completely filled and zero flow is assured. 

5.3.2  EasyConnect and OEM Model 

Zero adjustment of the flow sensor can be started with the relevant digital input of the PLC (see 

Table 15

 for 

OEM

 and 

Table 14

 for 

EasyConnect

 model) or the 

RS485

 interface of the drivers (see 

Section 5.2.2

). 

With the user panel 

LUI-B.1

 zeroing can be done manually as for the 

Stand-Alone

 model (see 

Section 5.1.2

). 

It is important to prepare the flow sensor as described in 

Section 4.8

 and to assure that the hydraulic circuit is 

completely filled and zero flow is assured.
