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 contact (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 "Relay
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 temporary
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 using a
single-phase inverter at a multiphase site. If an error occurs 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 protection device to recognise or
signal that an inverter is not feeding in or is disconnected from the
grid and to then disconnect the remaining inverters from the grid
using a telecontrol command.
Active output:
ON: The floating NO contact is on all the time the inverter is in operation
(as long as the display is not dark or is displaying something).
OFF: The floating NO contact is off.
Energy Manager:
E-Manager: Further details on the "Energy Manager" function may be found in
the "Energy Manager" section.
