1. Press 'ESC' on the display for at least 5 seconds.
INPUT
2. External control signal cancelled (open contact)
CONDITION
3. Return of mains voltage (Voltage OK at the inverter's output terminals)
S
Once it has left the backup mode, the inverter will check the conditions of the public mains network and,
after ensuring that Voltage and Frequency parameters are correct, it will start the reconnection sequence
to the same network.
5. Mode: Auto 1
In the Automatic 1 mode, the inverter may operate in backup if and only if the indicated condition exists:
1. Control/signal from external logic (to set the control, see section 5.4)
INPUT
CONDITION
S
This mode may be used whenever the indicated condition exists (previously established according to a
preset control logic), even in presence of the home network. The external control logic can be associated
with the state of the network by closing a NO contact in case of malfunction or absence of power in certain
sections of the system or in the entire dwelling. The activation signal may even be linked to a contact of the
Load Manager Relay installed in the REACT system by using the time window setting of the relay (see the
product's manual) or to any other external logic established by the user/designer during the design of the
system capable of automating the activation of the backup function.
In the event that the activation logic is not linked to a power failure, when Condition 1 occurs, the inverter
will disconnect from the network and switch to backup operation mode.
A possible scheme that can be designed and that describes the operation of this mode is shown below:
The following STOP conditions must be met for the backup mode output:
INPUT
CONDITION
S
Auto 1: Backup operation to send external control from automatic logic
