7. MENU AND CONFIGURATION PARAMETERS
The battery charger is controlled by a 32-bit Microcontroller
installed on the control board. All parameters are saved
into a EEPROM. The settings are configured into two categories:
1. Charger active parameters such as the alarm settings, O/P voltage and current, etc.
2. Charger active configuration: Temperature compensation, load sharing (if ordered). The calibration settings
are reserved for factory use only.
The battery charger allows users to adjust and visualize the following parameters:
 DC Output voltage and current;
 Equalize operation mode;
 Float operation mode;
 Charger current limit mode;
 Battery voltage remote sensing;
 Alarm adjustments;
 Temperature compensation;
 Load sharing;
 250 events monitoring (date and time stamp are optional);
 Reset alarms and relays;
 Measures :
 AC Frequency.
 Rectifier voltage.
 Voltage between positive output and chassis.
 Voltage between negative output and chassis.
 Remaining time for Equalize.
 Elapsed time for Equalize.
 Charger temperature.
 Battery temperature (optional).
 Battery Voltage discharge test (optional).
 Battery current discharge test (optional).
 Battery discharge time (optional).
 Relay test.
 LCD contrast adjustment.
