of the controller,
P

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
0
in the assisted commissioning
via 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".
The "CO" 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 all cap
valves 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,
•
With automatic make-up:
–
The vessel is automatically filled to 12% of its volume,
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.
Note!
Initial commissioning is completed and the device is in automatic mode.

Operating modes
8.1.1
Automatic mode
Use:
After initial commissioning has been successfully completed
Start:
Press "AUTO".
Functions:
•
In automatic mode, the controller monitors the following functions:
–
Maintaining pressure
–
Expansion volume compensation
–
Automatic make-up.
•
The "CO" compressor and the "PV" solenoid valve (optional) are regulated
by the controller so that the pressure remains constant in a regulation
range of ± 0.1 bar.
•
Faults are displayed on the control panel and in the app.
8.1.2
Stop mode
Use:
Stop mode interrupts automatic mode and is a prerequisite for manual mode.
Start:
Press "Stop" on the controller. The Auto LED of the control panel goes out. The
Stop LED lights up in yellow.
Functions:
Function monitoring is not performed in stop mode.
The following functions are deactivated:
•
The "CO" compressor is switched off.
•
The "PV" solenoid valve is closed.
Note!
If stop mode is activated for longer than 4 hours, an error message
appears on the device to signal an uncontrolled deactivation. This is also
indicated in the Reflex Control Smart app.
8.1.3
Manual mode
Use:
For testing and maintenance work
Start:
1.
In the display, switch the system to stop mode.
2.
In the app, switch the system to manual mode.
Setting
Maintenance
Manual mode
3.
Start manual mode.
4.
Select the desired function.
Switch the function on and off by touching the corresponding button:
•
The button is highlighted white. The function is switched off.
Press the desired button:
•
The button is highlighted green. The function is switched on.
Functions:
Manual mode allows you to select the following functions and to perform a test
run:
•
Compressor
•
Solenoid valve
•
Make-up
•
Potential free group fault.
