Connector reference: X07, X08 and X09

Section 4.5 Analog input

4.5.1 Standard analog inputs

Page 10

CMC NV – Airmaster Q1 Installation Guide – V1.0 – MANY1032A.EN
Three fixed analog inputs are available. All three have 2 dedicated connections:

 Analog input 1: Connections C-ANA1 and AN1

current input: 4 .. 20 mA

 Analog input 2: Connections C-ANA2 and AN2

current input: 4 .. 20 mA

 Analog input 3: Connections C-ANA3 and AN3

Selectable by software configuration: current (4 .. 20 mA),voltage (0 .. 10V) or external resistor (acting as
temperature sensor)

For Analog input 1 and Analog input 2, the C connections (C-ANA1 and C-ANA2) are voltage outputs (referenced to the GND of
the controller). The maximum current rating per output is 50mA. The voltage level is approximately 24 V dc.
These voltage outputs (C-ANA1 and C-ANA2) shall only be used with devices that provide the current for respectively AN1 and
AN2. Only connect external components to this input that comply with this specified current range.

Analog input 3 can function in three ways (selected by configuration software):

 Current input (4 .. 20 mA). In this case this input behaves as analog input 1 and 2. All remarks related to analog

inputs 1 and 2 apply to analog input 3.

 Voltage input (0 .. 10V). In this case C-ANA3 is connected to the GND of the controller. Hence the voltage source can

be connected on C-ANA3 en AN3 with the positive connection of the voltage signal to AN3. Protect this input against
any voltage outside of this specified range.

o Remark: Power (+) can be drawn from for instance C-ANA1 provided total current sourcing remains

according to maximum of 50mA.

 Resistor input (used with temperature sensor such as PT100, PT1000, KTY, NTC). The resistor shall be connected

between C-ANA3 and AN3.

Functional earthing

In case the external components demand for a GND connection (such as for functional earthing, It is recommended to use
shielded cabling for analog signals), it is advised to use the faston connections:

Connector reference: X03

4.5.2 Optional Analog input

Page 11

CMC NV – Airmaster Q1 Installation Guide – V1.0 – MANY1032A.EN

In X15 or X16 it is possible that one optional analog input is available.
Such input can be recognized by having 3 connection pins in its connector. If a connector with 2 connection pins is installed, it

is a RS485 connector (see further).
Note: on these 3 pin connectors a GND connection is provided.
In case an optional analog input is present, it behaves as Analog input 3. Hence all remarks related to Analog input 3 apply to

this input.
Connector reference: X15 or X16

Section 4.6 Analog output

The analog output provides a current ranging between 0 and 20 mA. The current leaves the controller through ANA-OUT to go
to the external device and shall return via AGND. For proper functionality the impedance of the external device shall be 500 Ω
resistive maximum.

Page 12

CMC NV – Airmaster Q1 Installation Guide – V1.0 – MANY1032A.EN

Functional earthing

In case the external components demand for a GND connection (such as for functional earthing, It is recommended to use
shielded cabling for analog signals), it is advised to use the faston connection:

Connector reference: X01

Section 4.7 Communication

4.7.1 Fixed RS485 Communication Connection

This connection shall only be used for connecting the controller with another component’s RS485 connection or a RS485 bus.
