4.3.7 Installation of RS485 Fieldbus for Flow Control Arrays

Figure 25

shows a flow control arrangement with the

RS485

fieldbus and its basic specifications.

Figure 25: Flow control array arrangement with RS485 fieldbus

Following points and information shall be considered:

➔

Testing has been done with arrangements of 8 systems. Higher number is possible but it is recommended to contact

Levitronix

Technical Service

department (see

Section 8

) for details and support.

➔

Address setting of the pump units can be done with the

Levitronix

Service Software

and a

PC. A USB/RS485

converter cable with integrated initialization network can be ordered according to

Table 4

➔

The

RS485

protocol for master communication is available at

Levitronix

on request.

➔

Do not use multiple master systems at the same time.

➔

Do not use closed ring arrangements.

4.4 Electrical Installation of Flow Sensor

1. Every sensor comes delivered with a calibration sheet. Check if the S/N on the calibration sheet corresponds to the

S/N on the type label of the sensor.

2. Please store the delivered calibration sheet or its data on a defined storage place in order to be able to refer to it in

case of problems.

3. Attach one of the sensor extension cables (

Table 4

Position 10a

) coming from the driver to the sensor connector.

4. When applying power, the flow control drivers needs about 10 seconds for a start-up procedure to be ready. In order

to get stable temperature and signals for flow converter and sensor 30 minutes shall be waited after power-on.

5. After start-up a Zero adjustment is recommended as described in
