EMERGENCY BATTERY
In case of power failure, an optional accessory to power the control unit is available.
The kit is composed of CB.24V battery charge card and two rechargeable batteries at 12V/1,2Ah, which can be fitted on
the back on the control unit container.
The CB.24V card must be connected between the secondary transformer and the 0/SLOW/24V/FAST inputs, as shown in
the diagram of Fig.2.
During mains powered operation, the DL2 green LED is switched on and the card maintains the battery charged.
If no mains power is available, the card powers the system through batteries, the DL1 red LED switches on.
A F10A fuse protects the control unit during operation with an emergency battery.
If no main power is available and batteries are down, both LED’s are switched.
The buffer battery works and progressively runs down until it reaches the value of 18V. When this value is reached, the
battery is disconnected.
During operation in case of power failure, the output, 24VAC accessories of the control unit, is polarised.
