LIS Pressure pick-up for calculating the filling level in the expansion vessel
A pressurisation unit monitors the filling level in the expansion vessel. When the
filling level in the expansion vessel falls below the minimum level, the
pressurisation unit sends a signal to the device controller. The controller
activates the pump. Mains water from the system separator tank is added to the
system circuit.
Proceed as follows:
1.
In the Customer menu, set the device to "Levelcontrol", see chapter 9.2.1
"Customer menu" on page 13 .
2.
The filling pressure for make-up with mains water must be at least 1.7 bar
higher than the "P
0
" minimum working pressure, see chapter 7.2
minimum operating pressure for the controller" on
page 9
Note!
You may combine the device with softening systems (Fillsoft, for
example); available as optional accessories, see chapter 4.6 "Optional
equipment and accessories" on page 5 .

Electrical connection
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 the system is voltage-free before installing the device.
•
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.
DANGER
Risk of serious injury or death due to electric shock
Some parts of the device's circuit board may still carry 230 V voltage even
with the device physically isolated from the power supply.
•
Before you remove the covers, completely isolate the device controller
from the power supply.
•
Verify that the main circuit board is voltage-free.
The following descriptions apply to standard systems and are limited to the
necessary user-provided connections.
1.
Disconnect the system from the power source and secure it against
unintentional reactivation.
2.
Remove the cover.
DANGER Risk of serious injury or death due to electric shock. Some
parts of the device's circuit board may still be live with 230 V even after the
device has been physically isolated from the power supply by pulling out of
the mains plug. Before you remove the covers, completely isolate the
device controller from the power supply. Verify that the main circuit board
is voltage-free.
3.
Install a screwed cable gland suitable for the respective cable. M16 or M20,
for example.
4.
Thread all cables to be connected through the cable gland.
5.
Connect all cables as shown in the terminal diagram.
–
For installer supplied fusing, comply with the connected loads of the
device , see chapter 5 "Technical data" on page 5 .
6.
Install the cover.
7.
Connect the mains plug to the 230 V power supply.
8.
Activate the system.
The electrical connection is completed.
