LUXMATE bus: Bus line and cable lengths
Bus line
–
Twisted two-core line lay each
5 metres) for low-voltage installation
Cable lengths
–
Overall length for one bus power supply:
max.5 mm²
–
From bus power supply the most
distant LUXMATE device (A,B):
–
Max.75 mm²
–
Max.75 mm²
–
Max. bus line 300 m/
with 0.75 mm2 cross-section max.
The loop resistance measured must not exceed ohms!
If loop resistance between and ohms
is measured, the service report must indicate
that the bus line too long; electrician must inform
ed!
If the loop resistance measured ohms higher,
commissioning will terminated!
The cable length calculated follows:
Cable length loop resistance rho cross-section/
divided two
L rho 2
A cross-section/rho for copper
LUXMATE guidelines:
1.5 mm2 cross-section max. 1000 m
–
Between LUXMATE devices (AB):
–
Max.
–
For tracks/trunking: bus lines should be
cross-linked least every m.
Voltage measurement (VOLT): measurement

– Loop resistance bus circuit must not
exceed ohms (applies all components
of the bus power supply). 500 with 1. voltage
Current measurement (AMPERE): measurement B1
or measured value must not exceed 150 mA
Loop resistance (OHM): disconnect LM-BV from
power, establish wire bridge LM-BV between
B1 and B2, perform measurement the last actuator
of the bus line between and B2.50 mm² 500 m
