LOCAL LAN NETWORK MANAGEMENT

5.1

PURPOSE OF THE LOCAL LAN NETWORK

The unit connection to the local network (LAN) allows to perform the following functions:

Balancing the operating hours among the different units by rotating the reserve units (Stand-by).

Turning on the reserve units in case other units should turn off due to an alarm, maintenance or power feed interruption.

Turning on reserve units to offset the excessive thermal load.

Checking up to 10 units with a single user terminal (shared user terminal).

Operating with all units based on the average temperature and humidity values read by the temperature probes only in the operating units.
OBLIGATION
To allow the LAN to operate correctly, the units must have the same software version and revision (e.g.: ME18r00).
If there is more than one version, update to the latest version or create two different LAN's.
ATTENTION
The ME software is not compatible with the previous LC versions.
5.2

PRELIMINARY OPERATIONS

In order to operate the unit correctly within the local LAN network, it is necessary to perform the following operations.
5.2.1

Network cabling

For the purposes of setting a local LAN network among the units, it is necessary for the installer to lay an electrical connection among the same by means
of a screened cable (not included in the supply).
INFORMATION
it is recommended to use twisted couple of AWG24 cabling (2 wires in total) + Belden 8723 or 8102 type sheath.
