Note: in case of block during start-up or excessive slow opening, it is recommended to add the
program to the antivirus exceptions of your PC.

4.2. “MAIN”section
The “MAIN” section indicates the correct functioning of the system with the related active alarms /
signal and permit the opening of the COM-port for ZHERO-PC communication.
4.2.1. COM-port opening
a) Select the language chosen in the bottom right;
b) Click: “Refresh list” top right;
c) From the drop-down menu select the COM marked as follows: “COM… UNE ZHERO S6”;
Press “OPEN”e and make sure that “Connected” appears in the status section.
Note: If the opening of the COM port is impossible, not detected or often went wrong we
recommend a restart of the system and the release of the photovoltaic system.
4.2.2. Checking the operation
Open the COM port in the ZHERO Status box and you will see:
•OK: in case of correct operation;
•ERROR: in case of system in alarm.
In “Alerts and alarms table”, all the alarms and signals will be displayed with an indication of:
•FAMILY: indicates whether the alarm is specific to one of the internal devices or
concerns the entire system;
•GROUP: represent the subdivision of the alarm family into groups of 8;
•BIT: number of the signalled bit;
•ALARM NAME: name assigned to the alarm;
•POSSIBLE CAUSES: one of the possible causes for which this alarm is generated is
indicated;
•POSSIBLE SOLUTION: a possible solution to the problem or indication for which ta
normal behaviour is indicated.
Note: In case the table remains, empty there are no anomalies or reports.

4.3. “OPERATION”section
The “OPERATION” section it is useful to view the firmware versions of the machine, the real-time
enhancement of the main variables and the status of the system (ON-GRID, OFF-GRID, ONLINE O
WARMUP ECC...).
In case the fields are empty or lost during operation, it means that the COM port has not been
opened or has stopped.
