Connecting Digital Devices
Cable length limitations, Digital bus (control interfaces in accordance with 15.5 of IEC 61347-2-3:2011):
Conductor x-section, AWG/mm
Cable length, ft./m
*overall cable length above 1000ft/300m shall be avoided
DC resistance must not exceed 4Ω; according to IEC62386-101:2014.
Both Electrical and Logical limitations of Digital bus shall be considered when sizing / designing of the lighting control system.
Electrical limitations of each Digital bus
Max current load on each bus = 175mA
When connecting devices calculate power consumption of
the devices on the bus
• Control Gear: 2 mA**
• Lightsweep™ Digital Switch Interface: 2 mA
• Lightsweep™ Digital Multisensor 2: 3 mA
Wiring Relay outputs
Maximum cable length of relay outputs: DC resistance must not exceed 10Ω (see table below)
Cable length limitations, relay drive outputs:
Conductor x-section, AWG/mm
Cable length, ft./m
Wiring Input interfaces on controller
Warning: negative terminals are common internally. Loops should be avoided
Maximum cable length for inputs: wiring DC resistance must not exceed 100Ω
Cable length limitations, analog control inputs (negative terminals are common internally):
Conductor x-section, AWG/mm
Cable length, ft./m
**care should be taken applying cable lengths above 1650ft/500m as it can harmfully influence stability.
Separation of circuits
Warning: the wiring shall be installed in accordance with National Electric Code and local codes rules; the power wiring
must be separated accordingly from the class 2 signal wiring
Power wiring - AC power input and the relay outputs
Signal wiring - Ethernet, input interfaces and Digital Bus A/B
Network Connectivity
Lightsweep™ system requires wired network for operation
and wireless (Wi-Fi) network for commissioning and setup
(In case of standalone deployment, this can be a temporary
network).
Lightsweep™ devices should be placed into an independent
broadcast domain in the network, separated from any other
devices and communications. These Controllers can obtain

their IP addresses with DHCP, therefore an active IPv4 DHCP
service should be available in this network segment. Static
IP addresses are not supported.
The hand held device with the commissioning application
should be connected to the same network segment. The
proper Wi-Fi coverage in the whole commissioning area is
an essential need.
