Indication on the
display
Meaning
Cancel null
balancing?
No
Select "Yes" or "No" on the controller display and confirm
with "OK" on the controller operator panel.
•
Yes: The "VG" primary vessel is fully emptied and the
device is installed as per the instructions.
–
Null balancing is still not possible, confirm with
"Yes". The start routine is terminated. Use the
customer menu to repeat the null balancing,
see chapter 9.2 "Configuring settings in the
controller" on page 12 .
–
Contact Reflex Customer Service, see
chapter 12.1 "Reflex Customer Service" on
page 17 .
•
No: The start routine restarts.
–
Check the prerequisites for the commissioning,
see chapter 7.1 "Checking the requirements for
commissioning" on page 10 .
Terminate
routine?
No
This message appears on the display only after null
balancing has been successful.
Select "Yes" or "No" on the controller display and confirm
with "OK" on the controller operator panel.
•
Yes: The start routine is terminated, the device
automatically switches to Stop mode.
•
No: The start routine restarts.
0 % / 2.0 bar
STOP
The level indication is at 0 %.
Note!
After successful conclusion of the start routine, you are in Stop mode. Do
not yet switch to Automatic mode.
7.4
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).
Upon completion of the start routine, you must vent the primary vessel and the
secondary vessels, if applicable.
•
Open the vessels' discharge ports to permit the air to escape.
•
Select Automatic mode on the controller's operator panel, see
chapter 8.1.1 "Automatic mode" on page 11 .
The "CO" compressor builds up the pressure required venting. This pressure is
0.4 bar above the set minimum operating pressure. The vessels' diaphragms are
pressurised to this level and the water side in the vessels is vented. Close the
discharge ports of all vessels after the compressor has automatically shut down.
Note!
Inspect all compressed air connections between the control unit and the
vessels for leaks. Subsequently, slowly open all cap valves at the vessels
to create the water-side connection to the facility system.
7.5
Filling the tanks with water
Prerequisite for fault-free filling is a make-up pressure at least 1.3 bar above the
set minimum pressure "P
0
".
•
Without automatic make-up:
–
Use the discharge ports or the facility system to manually fill the
individual tank to approximately 30 % of the tank volume, see
chapter 6.4 "Make-up and degassing variants" on page 8 .
•
With automatic make-up:
–
The tanks are automatically filled to approximately 12 % of the tank
volume, see chapter 6.4 "Make-up and degassing variants" on page 8
.
7.6
Starting Automatic mode
Automatic operation can be set after initial commissioning. Start the automatic
mode at the operator panel of the controller.
The following prerequisites must be met for automatic operation:
•
The device is filled with compressed air and water.
•
All required parameters are defined in the controller.
Press "Auto" for automatic mode at the controller operator panel.
•
The "Auto" LED at the operator panel illuminates to visually signal
automatic mode.
Note!
Initial commissioning is completed and the device is in continuous
operation.

Operating modes
8.1.1
Automatic mode
Use:
After initial commissioning has been successfully completed
Start:
Press "AUTO".
Functions:
•
Automatic mode is suitable for continuous device operation and the
controller monitors the following functions:
–
Pressurisation
–
Expansion volume compensation
–
Automatic make-up.
•
The "CO" compressor and the "PV1" solenoid valve are regulated by the
controller so that the pressure remains constant in a regulation range of ±
0.1 bar.
•
Faults are indicated and evaluated in the display.
8.1.2
Manual mode
Use:
For testing and maintenance tasks.
Start:
Press "Manual" on the controller. The Auto LED at the operator panel flashes to
visually indicate that Manual mode is active.
Functions:
Manual mode allows you to select the following functions and to perform a test
run:
•
"CO" compressor.
•
"PV1" overflow solenoid valve.
•
The solenoid valve of the "WV1" make-up.
You can switch several functions after each other and test them at the same
time.
30 % 2.5 bar
CO1!* PV1 WV1
•
Use the "Switch up/down" keys to select the
function.
–
"CO1" = compressor
–
"PV1" = Solenoid valve in the overflow line
–
"WV1" = solenoid valve make-up
(* selected and active units are marked with
"!").
•
Press "OK".
–
Confirm the selection or shut-down of the individual functions.
•
"Quit" button
–
Shut-down of the individual functions in reverse order.
–
Press "Quit" for the last time and the system moves in Stop mode.
•
"Auto" button
–
Return to Automatic mode.
Note!
Manual operations cannot be performed if safety-relevant parameters
would be exceeded. Switching is then disabled.
