2.2. Device front panel
At the front panel of the device can be found the following information:
MicroUSB – VIN
Input for the power supply. So as to provide an input voltage of 5VDC through a microUSB connector, a
DC-DC converter with the input range 7 – 50VDC is supplied.
Discover button
This button carries out two actions:
•Linking the device to the App: This action is fully explained on 3.- Configuration, installation and
start-up.
•Linking to a Wi-Fi network created by another Nayar Systems device: For example, if there is
a Nayar Switch installed, it is possible to connect to its Wi-Fi network, by pressing the Nayar
Switch Discover button and then, the one of BVA.
SW
Two microswitches with the following functionalities:
1 Activation / deactivation of CAN terminating resistors
2 Activation / deactivation of IPBus terminating resistors
CAN ( * ) / IPBus ( * )
•CAN H and L: Reception of CAN frames from lift controller
•IPBus H y L: Processing IPBus frames to transmit data through two electrical wires.
(*) On current product versions, these functionalities are not available.

4 position connector, including 2 relay connections (relay 1 and 2) and two independent common
contacts.
BVA 12 relays
4 position connector
4 position connector, including 2 relay connections (relay 1 and 2) and two independent common
contacts (COM1 and COM2). In such a way that COM1 contact corresponds to relay 1 and COM2, to

3. Configuration, installation and start-up
A complete installation with BVA devices requires the following elements:
• 1 Device per cabin: BVA 12 relays
• 1 Device per floor (compatible with 1 or 2 buttons): BVA 2 relays
In the following example the installation consists of 1 cabin and 3 floors, so the following elements are
required:
• 1x BVA 12 relays
• 3x BVA 2 relays
Hereinafter, the procedure to optimally install BVA devices is described.

3.1. Installation of BVA
Installation of BVA devices must be implemented near buttons, to make its installation easier and to
have good access to connectors from both sides. Moreover, it is highly recommended the installation of
the devices at half of the height of the floor, in order to avoid any interference with any devices located
at upper and/or lower floors.
Furthermore, switching off the power supply of the facility is recommended to be sure that the working
environment is safe.
It may be necessary to disassemble the lift car operating panel or external buttons for accessing at its
rear part, where the BVA device will be installed, in a way that the device will not be accessible by the
user of the lift.
Recommended material
• Wire diameter: 28 – 16 AWG (0.5 – 1.5mm²)
• Ties (Optional)
• Screwdriver for screws of 5.3mm diameter head
• Drill with a 6mm diameter bit
• 6mm plastic straddling dowel

3.1.1. Installation of BVA 12 relays at lift car/
s
1. Identify the buttons and the wiring that activates each button and its common contact.
2. Prepare the necessary wiring for installing the device: power, relay connection and common
contact wiring.
3. Identify the connection wires of buttons to the device, depending on relay configuration at
Net4Machines Smart Control App. Relay 1 common contact is independent from that of relay 2.
4. Wire the corresponding contacts of the button to the pluggable terminal of 14 positions and
connect to the BVA.
5. Prepare the wiring for the power supply of the device. For productos versions v3.0 and older, it is
necessary to supply power to BVA thanks to a DC-DC converter with a type B microUSB
connector. The converter must be connected to an electrical line with a voltage between 7 – 50
VDC. Plug the converter microUSB to the BVA.
6. Place the device at an isolated location from water and humidity.
7. Use the complements supplied to fix the product if necessary.
8. Connect the power supply of the facility and check that the power LED is powered on.

3.2. Configuration
It is highly recommended to configure the devices before installing them so as to assure Internet
connectivity of the Smartphone. After configuring the BVAs, it is important to properly identify the
devices with its location on the installation as well as the relays to be used in order to make easier its
later installation.
Devices can be fully configured through the App Nayar Systems Net4Machines Smart Control and
partially from the web platform. However, it is always necessary to complete the link the use of the App
from a Smartphone. Moreover, an online environment is required to correctly apply the configuration of
devices. BVA and Smartphone are connected through wireless connection by proximity using a 2.4GHz
radio link.
Any later modification of configuration may be done presentially and on an online environment.
