MOUNTING INSTRUCTIONS IN STEPS

Before you start mounting the unit, read carefully “Safety and Precautions”and

follow these steps. Choose a smooth solid wall surface for installation.

Follow these steps:

1. Make sure that the controller is switched oﬀ.

2. Unscrew the front cover and open the enclosure. Mind the wires that connect the

LEDs with the printed circuit board.

3. Fix the unit to the wall or panel using the provided screws and dowels. Mind the

correct mounting position and unit mounting dimensions (see Fig. 1 Mounting

dimensions and Fig. 2 Mounting position).

4. Insert the cables through the cable glands and do the wiring according to the

wiring diagram (see Table 1) while adhering to the information from section

“Wiring and connections” above.

4.1 Connect the power supply line (terminals L and N).

4.2 If applicable, connect the analogue / modulating inputs (terminals Ain1 &

GND / Ain2 & GND) to an external potentiometer or HVAC sensor with an

analogue / modulating output (0—10 VDC / 0—20 mA / PWM / digital (0

or1))

4.3 If applicable, connect the tacho inputs (if the connected motor features

tacho, these are used for feedback and control).

4.4 Connect the analogue output(s) (Aout1, GND & Aout2). e controller can

be used to control one or two motors simultaneously, so only one or both of

these outputs can be connected, depending on your application.

4.5 If applicable, connect the Modbus RTU communication cables.

4.6 If your device is ECMF8-EW version, connect the Ethernet cable (Ethernet

connection is the default setting).

4.7 Connect HVAC sensors, potentiometers or other slave devices to the RJ45

socket and/or Power over Modbus (PoM) terminal block (see Fig. 3).

5. Put back the cover and secure it with the screws. Tighten the cable glands.

6. Switch ON the main supply after all connections are done and checked.

7. Connect your installation to SenteraWeb and download the required application

speciﬁc ﬁrmware.

the selected ﬁrmware into the connected devices. After the download there is

the possibility to use the installation stand alone or to keep the internet gateway

connected.

VERIFICATION OF INSTALLATION

After connecting the unit to the main supply, the green LED on its cover should light

up to indicate that the controller is supplied. For status indication, see Table 2.

Table 2 LED indications

Green Normal operation

Blinking Yellow Oﬀ level activated for input 1, 2 or both.

Blinking Red Communication with external sensors is lost.

Safe operation depends on proper installation. Before start up, ensure the following:

■e main supply is connected correctly.

■Do not short-circuit the terminals or the input and output wiring.

■During operation, the unit must be closed.

■Switch ON the main supply after all connections are done and checked.

■If the unit does not work according to the instructions, the wiring connections and

settings need to be checked.

ATTENTION Disconnect main power supply before all servicing and maintenance. High Voltage on

the internal circuit!

TRANSPORT AND STORAGE

Avoid shocks and extreme conditions; stock in original packing.

WARRANTY AND RESTRICTIONS

Two years from the delivery date against defects in manufacturing. Any modiﬁcations

or alterations to the product after the date of publication relieve the manufacturer
