The UTL ARD continuously monitors the battery voltage, battery current, and inverter current. Any fault condition is enunciated by the use of status LEDs and relay output. The system aborts the backup operation in the event of any fault condition.
The backup power can be turned on automatically in the event of a grid power failure or on-demand from external trigger inputs. There are two external trigger inputs. One is automatic which becomes active only when there is no mains power and the other is active through ON/OFF switch manually.
When the grid is present the system monitors the battery charging condition. This aids in preventive maintenance the backup of battery.
Status LEDs indicate Mains ON, Battery ON, Battery Low, Battery Charging, Overload, System ON, Mains High, Short Circuit.
