Installation
When installing the KR 100 LSN, the factory-installed solder
distributors must be removed. A maximum of four
KR 100 LSNs can be installed per NVK 100 LSN. One solder
distributor is supplied per two KR 100 LSNs.
Coupler power supply
The LSN part of all LSN elements (couplers and detectors)
is supplied with power via the control panel's 2-wire LSN
line.
All LSN couplers are designed to loop through the power
supply (+V, -V) of subsequent couplers.
The maximum cable length of the separate power supply
(+V, -V) depends on the power intake of the couplers to be
supplied and their peripherals, if not powered by an
external source.
Cable lengths
Cable length per primary line (PL) or control lines
•
Maximum length unshielded cable – 10 m
•
Maximum length shielded cable – 500 m
The primary cables, control cables and contact cables from
the NVK 100 may not exceed a total of 500 m per network
processing implementer (NVU).
Optional KR 100 LSN relay module for LSN expanders
The KR 100 LSN relay module for LSN expanders is intended
for use in the NNK 110 LSN and NVK 100 LSN.
The KR 100 LSN is installed if the high power requirement
means the connected control elements cannot be
controlled directly from the LSN couplers, or in order to
enable zero-potential switching.
Up to four KR 100 LSNs can be installed per NNK 110 LSN
or NVK 100 LSN. One solder distributor is supplied per two
KR 100 LSNs.
