The automatic filling function ensures that the operating
pressure is maintained. If the operating pressure drops
below the set value, the filling valve opens until the set set
pressure is reached.
To protect against e.g. leakage, the filling valve closes in
the following cases:
• No pressure increase can be measured
• The set filling time is exceeded
The filling valve does not open within the set blocking
time or when the maximum number of fillings is reached.
