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:

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
