Initial commissioning
• 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.
6.6 Installation and commissioning certificate
 Note!
The installation and commissioning certificate can be found at the end of
the operating manual.
7 Initial 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",  27.
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 expansion line of the Reflexomat has been purged and cleaned of
welding residues and dirt before commissioning.
• The cap valve for draining the vessel is open.
• The system is filled with water.
• 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 pressure
0
maintenance system. The controller calculates the switching points for the "PV"
solenoid valve and the compressor from the "P

P = 0.0 bar for safety temperatures ≤ 100 °C

7.3 Venting the vessels
CAUTION
Risk of burns on hot surfaces
Excessive surface temperatures on the compressor can result in skin burns.
• Wear suitable personal protective equipment (safety gloves, for
example).
After setting the minimum operating pressure P
the app, the primary vessel must be vented. Proceed as follows:
1. Ensure that the cap valve is closed.
2. Open the draining valve.
3. In the app control panel, press on "Start".
4. Select the vessel size of your system.
The compressor builds up the pressure required for venting. This pressure is
0.4 bar above the set minimum operating pressure. The vessel's membrane is
acted on by this pressure and the water side in the vessel is vented. Close the
draining valves of the vessel after the compressor has been automatically shut
down.
 Note!
Inspect all compressed air connections between the control unit and the
vessel to ensure their leak tightness. Subsequently, slowly open the cap
valve at the vessel to create the water-side connection to the system
circuit.
7.4 Filling the tanks with water
Prerequisite for fault-free filling is a make-up pressure at least 1.5 bar above the
final pressure "P ".
e
• Without automatic make-up:
– Use the draining valves or the system circuit to manually fill the vessel
to approximately 30 % of the vessel volume as a function of the system
temperature,  6.4 "Make-up and degassing variants",  24.
• With automatic make-up:
– The vessel is automatically filled to 12% of its volume,  6.4 "Make-up
and degassing variants",  24.
7.5 Starting Automatic mode
Automatic mode can be set after initial commissioning. Start automatic mode at the
control panel of the controller.
The following prerequisites must be met for automatic mode.
• The device is filled with compressed air and water.
• All required parameters are defined in the controller.
Press "Auto" for automatic mode on the control panel of the controller.
• The "Auto" LED on the control panel illuminates to visually signal automatic
mode.
• The actual values "Pressure (bar)" and "Filling level (%)" are shown in
alternation on the display.
– Possible errors are shown on the display.
 Note!
Initial commissioning is completed and the device is in automatic mode.
