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, 8.6 "Starting
Automatic mode", 38.
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.
8.5
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
".

•
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, 7.4
"Make-up and degassing variants", 33.
•
With automatic make-up:
–
The tanks are automatically filled to approximately 12 % of the tank
volume, 7.4 "Make-up and degassing variants", 33.

Starting Automatic mode
Automatic operation is executed as conclusion of the initial commissioning. The
following prerequisites must be met for automatic operation:
•
The device is filled with compressed air and water.
•
All required settings are defined in the controller.
Start the automatic mode at the operator panel of the controller.
1.
Press "AUTO".
–
The "CO1" compressor is switched on.
Note!
The commissioning process is now concluded.

Operating modes
9.1.1
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.

9.1.2
Manual mode
Use:
For testing and maintenance tasks.
Start:
1.
Press "Manual mode".
2.
Select the desired function.
Functions:
Manual mode allows you to select the following functions and to perform a test
run:
•
"CO1" compressor.
•
Solenoid valve in "PV1" overflow line.
•
Solenoid valve "WV1" for make-up.
You have the option to simultaneously switch multiple functions and to test
them in parallel. Switch the function on and off by touching the corresponding
button:
•
The button is highlighted green. The function is switched off.
Press the desired button:
•
The button is highlighted blue. The function is switched on.
The change in the filling level and the vessel pressure are indicated on the
display.
Note!
Manual operations cannot be performed if safety-relevant parameters
would be exceeded. Switching is then disabled.
9.1.3
Stop mode
Use:
For device commissioning.
Start:
Press "STOP".
Functions:
Except for the display of information, the device is non-functional in Stop mode.
Function monitoring is stopped.
The following functions are deactivated:
•
The "CO" compressor is switched off.
•
The solenoid valve in the "PV" overflow line is closed.
•
The solenoid valve in the "WV" make-up line is closed.
Note!
The system returns an alarm if the Stop mode is activated for more than
4 hours.
If "Floating alarm contact?" in the Customer menu is set to "Yes", the
system outputs the alarm to the group alarm contact.
