System LMS

control and monitoring via optical and metallic communication cables
connection of all communication routes into a ring ensures reliable function even after
interruption of a cable or failure of one of modules; at the same time the system
immediately identifies precisely the location of failure
communication with the central unit via glass optical cable guarantees a 100%
resistance to electromagnetic interference even when the cable is laid in parallel with power cables
communication between the modules LMC and LLC up to the distance of 240 m via metallic screened cable with optically insulated inputs
reliable control of individual lamp or their groups
measurement of voltage of each lamp allows evaluation of its input power and to diagnose immediately its failure
easy configuration and control with use of the module LTP reduces costs and time necessary for maintenance of the system
the connectors used allow quick and easy module replacement

basic rack for placing of the LCU modules in transformer sub-station
contains moreover power supply circuits with their own back-up battery, modems for communication with the AMS system at the control
tower and optica switchboard
dimension: 600×1305×450 mm
weight: 80 kg
position for LCU: 4
power supply: 93-132 V/187-264 V, 50-60 Hz

control unit of the AMS system, which ensures communication between modems and LMC modules via two independent optical lines connected into a ring
optical input/output: 2×TX, 2×RX
power supply: 24 V DC

converter of optical communication via metallic line
situated near the airfield ground lighting
main function consists in connection of communication of the LCU module with the LLC
dimenion: 310×400×110 mm
weight: 8,4 kg
power supply: 1,8 A–6,6 A
optical input/output: 4×TX, 4×RX

ensures control and monitoring of individual lamps
connected between the transformer and signal lamp
two independent communication ports, through which it is connected with the LMC and other LLC into a ring

testing and programming device for the modules LLC and LMC
verify functionality directly on the field
powered (supplied) from internal accumulator, from a car battery or from mains via adapter
