DANGER
Risk of serious injury or death due to electric shock.
If live parts are touched, there is risk of life-threatening injuries.
•
Ensure that the system is voltage-free before installing the device.
•
Ensure that the system is secured and cannot be reactivated by other
persons.
•
Ensure that installation work for the electric connection of the device is
carried out by an electrician, and in compliance with electrical
engineering regulations.
All electric connections between control unit and expansion vessel are pre-
installed.
1.
Connect the mains plug to the 230 V power supply.
2.
Activate the system.
The electrical connection is completed.

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.
6.5.2.1
Connecting the RS-485 interface
•
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 9 .
•
When using the device with a control centre not supporting an RS-485
interface (RS-232, for example), you must use a corresponding adapter.
