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 all phases of the mains power supply to the product are
disconnected prior to installation.
•
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 communication
with control centres or other devices.
The following data can be requested:
•
Pressure and filling level.
•
Compressor operating states.
•
Operating states of make-up via solenoid valve.
•
Aggregate volume of the FQIRA + contact water meter.
•
All messages, 9.4 "Messages", 23.
•
All entries in the error memory.
6.5.2.1
Connecting the RS-485 interface
•
Use a shielded cable to connect the interface to terminals 1 – 6 of the
circuit board in the control cabinet.
For connecting the interface, 6.5 "Power Supply", 21.
–
•
When using the device with a control centre not supporting an RS-485
interface (RS-232, for example), you must use a corresponding (on-site)
adapter.
Note!
For connecting the interface use, for example, a cable with these
properties.
•
LIYCY (TP), 4 × 2 × 0.8, maximum overall bus cable length 1000 m.

Commissioning
Note!
Commissioning and maintenance work must be carried out and
confirmed by specialist personnel or the Reflex Customer Service.
Note!
The app guides you through commissioning 9.1 "Reflex Control
Smart", 23.
7.1
Requirements for initial commissioning
The Reflexomat will be ready for initial commissioning when the tasks described
in the "Installation" chapter have been completed.
•
The Reflexomat has been located.
•
The weight measuring cell is connected.
•
The water-side connection of the vessel to the system circuit has been
established.
•
The vessel is not filled with water.
•
The connection pipes of the Reflexomat have been purged and cleaned of
welding residue and dirt before commissioning.
•
The draining valves of the vessel are open.
•
The entire system has been filled with water and all gases have been
vented in order to ensure circulation throughout the entire system.
•
The electrical connection has been created according to applicable
national and local regulations.
7.2
Reflexomat switching points
The "P
" minimum operating pressure is determined by the location of the
0
pressure maintenance system. The controller calculates the switching points for
the "PV" solenoid valve and the "CO" compressor from the "P
operating pressure.
