N-A4.2 Addressing <F2>
Conventional mode address: PP
When several NMV-D2M’s or MFT(2) actuators communicate over the
MP-Bus they must be clearly identifiable.
Bus mode address: MP1...MP8
N-A4.2.1 Address setting PP / MP
- Conventional mode setting ‘PP’ (Point-to-Point)
The ‘PP’ address is selected when an NMV-D2M under conventional con-
trol is connected to the PC-Tool.
See Connection diagram N-A2.1 and N-A2.2.
When an NMV-D2M is addressed ‘PP’ it is automatically assigned pa-
rameters for conventional mode.
For VAV, modulating control is effected with 0/2...10 V DC or, for CAV, by
means of step control. The signal for the actual value of volumetric flow
U5 is available at Terminal 5.
An NMV-D2M set for bus mode (MP) can be reset for conventional control
by addressing for ‘PP’.
- Bus mode setting ‘MP’ (Multi-Point)
Address ‘MP1...MP8’ is selected when several NMV-D2M’s or other Be-
limo MFT(2) actuators are incorporated into a higher level system via the
MP-Bus. In this case the connection is always made at the bus interface,
e.g. UK24LON and never directly to the communication socket of the
NMV-D2M. See Connection diagram N-A2.3.
If an NMV-D2M is given an MP address ‘MP1...MP8’ it will automatically
be assigned parameters for MP-Bus operation. In this case control is ef-
fected digitally over the MP-Bus.
N-A4.2.2 Methods of addressing
The screen mask for addressing the NMV-D2M is called from the menu,
the toolbar or the <F2> function key.
There are two methods available:
- Addressing by manual disengagement push-button
- Addressing according to serial number
