Backup function
The backup function allows the activation of a supporting cabinet in case
of unexpected switch-off of the main cabinet.
Two types of backup management are available:
• HBT: control on the heartbeat of the main control
• BMS: control by supervisor
The HBT control allows the activation of the backup cabinet keeping
controlled the heartbeat (digital output HBT) of the main Optimist. Wiring
the digital contact HBT with the BKUP input of the backup cabin, the
backup function check if the heartbeat is active (BKUP contact closed). If
the signal dies (BKUP contact opened), the backup cabin starts working.
The BMS control check the status of the DIG 75 variable.
If the variable is 1, the backup cabin is off ; if it switches to 0, the backup
cabin starts working.
Note: The enabling of the backup function must be set only in the
Optimist for backup, inside “Zone Menu

done from the main cabin to the backup one and vice versa.
