Protection of Supply Cables
To ensure protection against short-circuits or overload in the supply cables from the
customer's power system, the lead cross sections used have to be selected and protected
according to the national standards.
Depending on the power supply concept, the LMS1xx must be protected using the following
fuse(s) in the supplying circuit(s) at the start of the supply cable(s):
Separate power supply voltages for sensor and heating
The sensor consums the maximum current at the lowest permissible supply voltage for
the device compared to the heating.
Recommended fuses: sensor: 2 A slow-blow, heating 2 A slow-blow
Collective power supply voltage for sensor and heating
The heating consums the maximum current at the highest permissible collective supply
voltage for the device compared to the sensor.
Recommended fuse for sensor incl. heating: 4 A slow-blow
Data interface RS-232 and Ethernet (see also
section 6.3.3 “Boundary conditions for the
Device disconnector – installation of a switch in the supply cable
A switch, emergency stop switch, or similar, must be installed in the supply cable to the
device in order to reliably disconnect the device from the supply voltage in the event of a
fault. If the sensor and heater are supplied by separate supply voltages, both supply cables
must be routed via the switch.
