Displayed if there is no system monitoring present on
the inverter.
Relay (floating
contact switch) Status codes (state codes), the status of the inverter (e.g. feeding energy into the
grid) or Energy Manager functions can be displayed using the floating switch con-
tact (relay).
Setting range Relay mode / Relay test / Switch-on point* / Switch-off
point*
* these are only shown if the "E-Manager" function has been activated under "Re-
lay mode".
Relay mode
The following functions can be shown using relay mode:
- Alarm function (Permanent / ALL / GAF)
- Active output (ON / OFF)
- Energy Manager (E-Manager)
Setting range ALL / Permanent / GAF / OFF / ON / E-Manager
Factory setting ALL
Alarm function:
ALL / Per-
manent: Switching the floating switch contact for permanent and tem-
porary service codes (e.g. brief interruption to energy being
fed into the grid, a service code occurs a certain number of
times a day - can be adjusted in the "BASIC" menu)
GAF As soon as GAF mode is selected, the relay is switched on.
The relay opens as soon as the power stage set registers an
error and goes from normally feeding energy into the grid to
being in an error state. This means that the relay can be used
for fail-safe functions.
Application example
It may be necessary to perform phase compensation when us-
ing a single-phase inverter at a multiphase site. If an error oc-
curs on one or several inverters and the connection to the grid
is broken, the other inverters must also be disconnected to
maintain the phase balance. The "GAF" relay function can be
used in conjunction with the Datamanager or an external pro-
tection device to recognise or signal that an inverter is not
feeding in or is disconnected from the grid and to then dis-
connect the remaining inverters from the grid using a telecon-
trol command.
Active output:
ON: The floating NO contact is on all the time the inverter is in op-
eration (as long as the display is not dark or is displaying
something).
OFF: The floating NO contact is off.
