8.2 START FROM BATTERY ONLY, NO INPUT MAINS VAC
No. 9: Push-button, for 3 sec., in the front panel for switch ON the system without the “Mains input
Vac” but only the battery connected. (Not present in CBI 2410XX and CBI 485XX)
No.12: (Jumper n.5) It is also available the same function for remote start from the battery, via
RTCONN cable connected in the Push-button mounted on front Panel of the external system.
Standard function for all products, Size 2 only with code CBI2410A/S and CBI485A/S. Do not leave
jumper in this position, otherwise the system will discharge completely the battery. Only push button.
8.3 BUFFERING TIME SETTING (SIZE 3-4)
No.15: On Size 3 and Size 4 models, is possible to set a buffering time. It can be selected by setting the
desired value on the rotary switch 15. Buffering time is initiated when the mains is switched OFF. The
LOAD output will be ON for the selected time.

If the switch is in position 0, the LOAD output will be in ON state until the battery is completed discharged.
Any way to prevent damage risks, the unit disconnects the batteries when a minimum voltage level is
reached.
The LOAD output will be in ON state until the battery it is completed discharged. It is however possible to
request factory customized versions with specific buffering time setting, for units Size 1 or 2, you have
two choose the extension CBIxxxxASDx.
9 BATTERY CARE
The Battery Care philosophy is based on algorithms that implement rapid and automatic charging, battery
charge optimization during time, flat batteries recovery and real time diagnostic during installation and
operation. Elements in short circuit, accidental reverse polarity connection, disconnection of the battery,
can easily be detected and removed by help of Blink Code of Diagnosis Led; during the installation and
after sell. Each device is suited for all battery types, it is possible setting predefined curves for Open Lead
Acid, Sealed Lead Acid, Gel, Ni-Cd (option). They guarantee battery reliability in time by continuously
testing the internal impedance status, avoids any possible risk of damages and grants a permanent,
reliable and safe connection of the battery to the power supply. The system, through a battery stimulation
circuit with algorithms of evaluation of the detected parameter, is able to recognize sulphated batteries or
batteries with a short-circuited element. Battery Test: Automatic. Every 60 sec. check battery connection.
Every 220 minute in Float charge, make the test of the battery efficiency is done. The Battery Fault will be
monitored by relay and led blinking.
9.1 BATTERY CHARGE IN TEMPERATURE COMPENSATED ENVIRONMENT
No. 11 Remove the window label to find the connector: Auxiliary Output “AUX 1”
It is possible to connect the Temperature sensor probe and apply it on the battery.The function of the
probe is for temperature battery compensation. With this it is possible to active the specifications of the
EN54- fire certification.
Size 1,2,3
Size 4
9.1.1 Battery Temperature Compensation Charge (not for NiCd)
Connecting to Auxiliary Output AUX1 the cable RJTEMP (supplied separately), the CBI will vary the
voltage of battery charging depending on the temperature:
Fast Charge
Float charge
+/-5mV/°C x n. of Cells from -8°C to +60°C
+140mV/Cell ÷ -200mV/Cell compared to the value at
20°C
+/-3mV/°C x n. of Cells from -20°C to +60°C
+120mV/Cell ÷ -120mV/Cell compared to the value at
20°C
The device stops to charge the battery If the temperature is less than -20°C or greater than +60°C. The
sensor placed on cable RJTEMP must be applied on the battery.
9.2 CHARGING CURRENT LIMITER:
No.3 In order to protect the battery from excessive charging currents, the device allows
you to limit the maximum charge current by adjusting the trimmer. It allows you to limit
from max In up to 20% of current In. To determine the maximum battery charge current,
see the battery manufacturer's Data Sheet, If it is not possible, consider that on average
the maximum charge current is 10% of Ah's rated battery current; The data is suitable
for both Lead Acid and NiCd batteries.
9.3 BATTERY MANAGEMENT CONFIGURATIONS (SIZES 1,2,3,4)
No.18 Preliminary Operations: One device for all battery types.
