6.5.2 RS-485 interface
This interface is used to retrieve all controller data and to enable the
communication with control centres or other devices.
The following data can be requested:
– Pressure and level.
– Compressor operating states.
– Operating states of the ball valve in the overflow line.
– Operating states of make-up via solenoid valve.
– Aggregate volume of the FQIRA + contact water meter.
– All messages, see chapter 9.2.2 "Messages" on page 14 .
– All entries in the fault memory.

Note!
If required, please contact the Reflex Customer Service for the protocol
of the RS-485 interface, details of the connections and information
about the accessories offered.

• Use a shielded cable to connect the interface to terminals 1 – 6 of the main
board in the control cabinet.
– For connecting the interface, see chapter 6.5 "Electrical connection"
on page 8 .
• When using the device with a control centre not supporting an RS-485
interface (RS-232, for example), you must use a corresponding adapter.
 Note!
• For connecting the interface use only a cable with these
properties.
– LJYCY (TP), 4 × 2 × 0.8, maximum overall bus length
1000 m.
