VAV – Module NMV-D2M

N-A Applications

N-A 1 VAV-Compact NMV-D2M

The PC-Tool Module NMV-D2M has been d esigned specifically for the
VAV-Compact NMV-D2M and its use in connection with CAV and VAV air
boxes.

N-A1.1 Customised versions

Belimo VAV-Compact controllers are control devices that have been
manufactured for specific customers and are produced individually for
various air box manufacturers (OEMs). Therefore, each version is an op­timum match for the components used by particular manufacturers, such
as measuring transducers, damper spindles and mounting systems.
Some customised versions have different operating step control systems
than the standard NMV-D2M. The technical documentation p rovided b y
the manufacturers of the air boxes should be given close attention.

N-A 1.2 Support for …

… VAV-Compact NMV-D2 / NMV-24V / NMV-24D

These device s are not sold any more and are not supported by PC-Tool
V2.

... VAV-Universal VRD2 / VRD2-L / VRP / VRP-STP

are not supported by PC-Tool V2.

... VAV ...24-MFT2 actuators

These actuator types need the MFT -PC Module of PC-Tool.
Therefore, please change over to the appropriate module.

... VAV ...24 V actuators

These types are pure VAV actuators from the VAV-Universal range and
are not supported by PC-Tool V2.

N-A4.2 Addressing <F2>

Conventional mode address: PP
When several NMV-D2M’s or MFT(2) actuators communicate over the

MP-Bus the y must be clearly identifiab le.
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 con­trol 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 pa­rameters for conventional mode.
For VAV, modulating control is ef fected 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 Be­limo 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. I n this case control is ef­fected 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

VAV – Module NMV-D2M

N-A4.2.3 Addressing by manual disengagement push-button

Procedure:

- Set the required address in the ‘MP address’ field.

- Activate ‘Manual addressing by acknowledgement’

- Press ‘OK’

- Press the manual disengagement push-button on the NMV-D2M. An

appropriate signal is given if the setting of the address is successful.
Repeat the procedure if a fault alarm is given.

N-A4.2.4 Addressing according to serial number

Procedure:

- Set the required address in the ‘MP address’ field.

- Activate ‘Addressing according to serial number’

- Enter the serial number (by hand or bar code reader)
When there is a direct link to the actuator the serial number read from

the NMV-D2M appears as the default value.

- Press ‘OK’

- An appropriate signal is given if the setting of the address is successful.
Repeat the procedure if a fault alarm is given.

N-A4.3 Reset to OEM setting <F5>

This f unction allows changed settings of operating volumetric flow to be
reset to the unit m anufacturer’s def ault values.
The following values are reset:

V’max
V’mid
V’min

Reset to OEM setting <F5>

Practical tip – Address stick er

Detach the large sticker and paste it on to the

appropriate installation plan.

This will allow addressing to be carried out
later with no need for direct access to the

controller. It also forms part of the installa

tion’ s

documentation.
