Dynamic Load Management (DLM) for GLB
Wallboxes in group
Note: Do not change any settings on the internal energymeter.
To activate DLM for a group of GLB Wallboxes, a GARO Modbus
energy meter must be installed in the supply distribution box. It
is also possible to install a 2nd Modbus energy meter when you
need to monitor the consumed energy at more than one place.
The following energy meters are approved:
• GNM1D-RS485,
• GNM3D-RS485
• GNM3T-RS485 (current transformer 3-phase. Max current is
based installed current transformer)
• CG EM 112
• CG EM 270
• CG EM 271
For use in systems with local electricity produktion (solar-, wind etc)
• GNM3D-LP RS485
• GNM3T-LP RS485N (current transformer 3-phase. Max
current is based installed current transformer)
Note the energy meter’s Modbus address must be set to 100 and
(101 for the 2nd energy meter).
Address 100 and 101 require setting to be done in the web
interface. SW1 is not valid. When less than 6A availavble current
in the system, the wallboxes will not paus charging.
The energy meter continually measures the total energy
consumption for each phase. Data is transmitted to the first
wallbox (GLB Master), which controls the charging current per
phase for the entire system in order to prevent the main fuses from
tripping. When using a single-phase energy meter, the meter must
be set to the same phase as all of the wallboxes.
A maximum of 50 GLB Wallboxes may be connected by a
shielded twisted pair cable, which is connected to the GLB
Wallbox connection terminal labelled ‘Data Link’.
Installation of Datalink according to (figure 8)(figure 9).
