Page 15: Combinations Of Nfe And Mve - Areas Of Application
5.2 Combinations of NFE and MVE – areas of application The replenishment for stationary installation can be pressure or level-controlled in adjustable, monitored time intervals or replenishment quantities and serves primarily to compensate for loss quantities in the system, but also for initial filling or refilling (only MVE1). NFE1.x + MVE1 System separator variant for automatic replenishment from domestic water networks... - Page 16 NFE2.x + MVE2 NFE2.x MVE2 Variant for automatic level-controlled replenishment from district heating networks in compressor-operated systems for external pressure maintenance (Flexcon M-K/U or similar with SDS/SPC control unit) whose system pressure is at least 0.5 bar below the system pressure of the district heating system.

Page 17: Mode Of Operation Of Nfe + Mve1
6. Mode of operation of NFE + MVE1 6.1 Control types Level controlled Control is effected by means of an external potential-free signal or a potential signal (230 V), depending on the control unit used, a pump or compressor-controlled pressure maintenance system. - Page 18 Runtime monitoring (in automatic mode AUTO) The operator has the option of parameterising A Cycle these freely. If the following conditions are not met, B Pause C Time window the system goes into error. The potential-free fault contact is opened until manual acknowledgement takes place.
- Page 19 Monitoring, pressure increasing time (in automatic mode AUTO) Within this defined replenishment time the system pressure must increase by at least 0.1 bar.If this condition is not met, the system goes into error. The potential-free fault contact is opened until manual acknowledgement takes place.This monitoring can be switched off by using the input 0 min.

Page 20: Mode Of Operation Of Nfe + Mve2
The solenoid valve is controlled directly (230 V/50 Hz). Depending on the level, the solenoid valve (MV) is switched by the Flamco SDS or SPC pressure maintenance control unit in order to control the filling volume of the expansion vessels. The preconditions for a fault-free functionality are, among other things, correct installation, proper connection to the SDS or SPC pressure maintenance control unit and operation within the technical parameters. -

• However, the modules can also be fixed to other suitable mounting points with the aid of the enclosed Flamco pipe clamps of the BSA series. • The replenishment modules are to be mounted free from support forces and other external additional loads. -
Page 22: Hydraulic Connection
8.2 Hydraulic connection • First, the supply line (A) is to be flushed sufficiently. • The stopcocks of the replenishment must first be kept closed and sealed in the corresponding lines. • The minimum nominal size of the supply and system connection cables must not be less than DN 15. - Page 23 SELV 28 29 30 31 32 33 34 35 36 10 11 12 13 14 15 16 17 18 INPUT SIGNAL RS485 External replenishment request (230 V/50 Hz) 27 26 25 24 23 22 21 20 19 9 8 7 6 5 4 3 2 RS485 INPUT SIGNAL External...
- Page 24 In contrast, in the case of an existing potential-free contact of the pressure maintenance control unit (Flamco control component F, M-K / S, MP10-40 or SDS-PA contact or SPC) for replenishment triggering, actuation on the SCU must be effected at other terminals. Here, terminals 21 and 22 are to be used on the SCU control unit and the corresponding terminals for potential-free contact on the pressure maintenance control unit.
