2.2.1 Controls
Up/Down Arrows – The Up and Down arrows offer no function outside of Configure mode. When in
configure mode the up and down arrows allow the customer to navigate menus and increase or decrease
values.
Float/Equalize Button – The Float/Equalize Button allows the user to manually switch between float mode
and equalize mode. When the ESCR is in equalize mode, line two of the display will switch between “EQUALIZE
MODE” and the time remaining.
Lamp Test Button – The Lamp Test button allows the user to check the function of all of the Front Panel LEDs
without affecting the operation of the rectifier. While the lamp test is running all of the LEDs flash and a
sequence of numbers is written to the display.
Reset/Back Button – Under normal system operation the Reset/Back Button operates as the reset button.
Pressing reset allows the user to restart the rectifier. Upon restarting the ESCR will once again go through the
start-up sequence describe in section 2.1.3. In the Configure mode the Reset/Back button operates as the back
button. Pressing the back button allows the user to navigate to a previous screen or out of the configuration.
Configure/OK Button – The Configure/OK button brings the ESCR into configuration mode, allowing the user
to set charger parameters in Basic Settings as well as Float Voltage, Equalize Voltage, Equalize Timer Current
Limit, Temperature Compensation and Alarm settings. Once in configuration mode this button becomes the OK
button which is used to make selections within the menus.
2.2.2 LED
Indicators/Alarms
LCD Display – The LCD
Display show the output DC voltage and output DC amperage of the ESCR 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 ESCR is in float mode.
Equalize LED (Amber) – The Equalize LED will illuminate when the ESCR is in equalize mode.
AC On (Green) – The AC On LED will illuminate whenever AC voltage is present at the ESCR input terminals.
Charger Fail LED (Red) – The
Charger Fail LED will illuminate when the charger is not able to regulate the
output voltage. The LED will stay lit, even after the alarm conditions clear up, until the ESCR unit is reset. A set
of Form C contacts is also provided to enable the customer to connect a remote annunciator.
Battery Fault LED (Red) - The Battery Failure LED illuminates to indicate a 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 rectifier is operating in a current limit
condition
High DC (Red) – The High DC LED will illuminate when the DC output voltage of the ESCR exceeds the preset
high voltage alarm value. The high voltage value is adjustable and can be set in Configure 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 ESCR falls below the
preset low voltage alarm value. The low voltage value is adjustable and can be set in Configure 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. 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.
