•
ALARM: the relay is activated in the case of alarm (code E).
For example, if the N.O. (or N.C.) contact is chosen, it will remain open (closed) until
an error occurs in the inverter (IT DOES NOT SWITCH OVER IN CASE OF
WARNING or code W); once an error has occurred in the inverter, the relay switches
its status to closed (open). The contract remains in this position, i.e. switched over
with respect to its rest position, until normal operation, i.e. operation in parallel with
the grid, is restored.
•
ALARM (conf.): the relay switches over in the event of alarms (code E) or
warnings (code W) chosen from a list by the user (the list may also show
selections which are not designed for the specific model, consult table 5.4
when choosing).
For example, if the N.O. (or N.C.) contact is chosen, the contact will remain open
(closed) until in the inverter an error occurs or warning is issued from those selected;
once in the inverter the error has occurred or warning issued, the relay switches its
status to closed (open). The contract remains in this position, i.e. switched over with
respect to its rest position, until the error code or warning is solved.
•
TWILIGHT: the relay switches only when the input voltage set for grid
connection is exceeded.
For example, if the N.O. (or N.C.) contact is chosen, the contact will remain open
(closed) until the inverter reaches a Vin which is greater than that selected for grid
connection. The contact will remain in this position, i.e. switched over with respect to
its rest position, for the time the inverter is on (even if disconnected from the grid).
This mode is useful for disconnecting any large output transformers which may incur
large levels of consumption during the night.
To select the alarm contact operating mode, access the Alarm submenu from the
Settings menu, select the desired operating mode by using the UP and DOWN arrows,
and push the ENTER key to confirm your choice.
