2.2.2 LED Indicators/Alarms
LCD Display
– The LCD
Display shows the output DC voltage and output DC amperage of the ESCR125 at all
times. The second line of the display shows the mode of the charger, as well as displaying the different alarm
conditions, should they occur.
Float LED (Green)
– The Float LED with illuminate when the charger is in Float Mode.
Equalize LED (Amber)
– The Equalize LED will illuminate when the charger is in Equalize Mode.
AC ON (Green)
– The AC ON LED will illuminate whenever AC voltage is present at the charger input
terminals.
Charger Fail LED (Red)
– The
Charger Fail LED will illuminate when the charger is unable to regulate the
output voltage. A set of Form “C” contacts is also provided to enable the user to connect a remote annunciator.
Battery Fault LED (Red)
– The Battery Failure LED illuminates to indicate an issue with the battery.
Conditions that would cause this LED to illuminate are an open or high resistance battery, or a missing battery.
Current Limit (Red)
– The Current Limit LED will illuminate when the charger is operating in a current limit
condition.
High DC (Red)
– The High DC LED will illuminate when the DC output voltage of the charger exceeds the
preset high voltage alarm value. The high voltage value is adjustable and can be set in Configuration Mode. A
set of Form “C” contacts is also provided.
Low DC (Red)
– The Low DC LED will illuminate when the DC output voltage of the charger falls below the
preset low voltage alarm value. The low voltage value is adjustable and can be set in Configuration Mode. A set
of Form “C” contacts is also provided.
AC Fail (contacts only)
– The AC Fail alarm does not have an LED indicator, however, an AC Fail message
appears on the LCD display and the AC ON LED will turn off. A set of Form “C” contacts is provided for an AC
Power Failure Alarm annunciation. These contacts change state when AC Fail threshold is reached.
