Pressure transducer
The pressure transducer sends a signal to the controller if the pressure drops below the filling pressure of the facility system. The
controller activates the pumps. Water is added to the facility system from the system separator vessel. The float valve in the system
separator tank ensures a water supply from the make-up system.
To prevent potential dry-running, an insufficient water switch in the system separator tank will shut down the pumps, if required.
The device controller monitors the make-up with water in the facility system. These functions are monitored by the controller:
•
Make-up time.
•
Make-up cycles.
•
Make-up quantity.
– Only if an optional contact water meter is installed
The controller interrupts the make-up when the set make-up time or the number of make-up cycles is exceeded. Small leaks in the
facility system are so detected.
The make-up 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 .
