The pressure transducer sends a signal to the controller if the pressure drops below the filling pressure of the plant system. The
controller activates the pumps. Water from the vacuum spray pipe is added to the plant system. The motor ball valve regulates the water
inflow into the vacuum spray pipe. Either gas-enriched water from the plant system is degassed in the vacuum spray pipe or water from
the system separator tank is added to the vacuum spray pipe. The float valve in the system separator tank ensures a water supply from
the makeup system.
To prevent potential dry-running, the integrated insufficient water protection unit in the system separator tank and the vacuum spray
pipe will shut down the pumps, if required.
The device controller monitors water degassing and makeup in the plant system. These functions are monitored by the controller:
• Makeup time
• Makeup cycles
• Makeup quantity
• Degassing
– Continuous degassing
– Interval degassing
The controller interrupts the makeup when the set makeup time or the number of makeup cycles is exceeded. Small leaks in the plant
system are detected in this way.
The makeup quantity is controlled by the controller if an optional "FQIRA+" water meter is installed. For the optional water meter, see
chapter 4.6 "Optional equipment and accessories" on page 15 .
