Digital switching outputs
The NAV210 has three digital switching outputs.
The outputs can be used as digital switching outputs to ground, as floating outputs, or as
resistance-monitored outputs (see section “Wiring inputs and outputs on the NAV210” on
page 41).
For each output, configure whether it should be switched via SOPAS ET telegrams or
whether it should be used to signalize device readiness.

3.9.1
System requirements of the NAV210
The user will require the following to commission and operate the NAV210:
•
Supply voltage of 24 V DC ± 15 %, created according to IEC 60 364-4-41 (VDE 0100,
Part 410), minimum power output 40 W; 60 W when used for heating.
•
Standard Intel Pentium PC or compatible, minimum Pentium III 500 MHz.
– RAM: at least 256 MB, 512 MB recommended
– Operating system: MS Windows 2000, XP, VISTA, or 7
– Monitor: at least 256 colors, 65,536 recommended
– Screen resolution: at least 800 × 600
– Hard drive: at least 220 MB free disk space available
– Data interface: RS-232 or Ethernet (see section 5.3.3 “General requirements of the
data interfaces” on page 39); if necessary, use an RS-232 converter if the PC
interface and the NAV210 interface do not correspond
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
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.
