PS Series Inverter/Charger
Part No. 3597
Rev. D: November 23, 1999
FLOAT (GREEN)
Battery This indicator will be on when the battery voltage has reached the Float Stage of the
charging process. It will now regulate the charging process to the SET FLOAT VOLTS DC setting
from the BATTERY CHARGING (10) menu heading. The SET FLOAT VOLTS DC setting
provides a maintenance charge to the battery until another Bulk Charge Cycle is initiated or the
AC source is disconnected. If a generator is manually controlled and powering the battery
charger, the FLOAT indicator will come on to indicate that the generator should be turned off,
since the battery is now fully charged.
This indicator is also used to indicate the regulation setpoint when the inverter is operating as an
Utility Inter-Active Inverter (SELL mode). The indicator will blink slowly to indicate the battery is
regulated to the SET BATTERY SELL VOLTS DC setting from the BATTERY SELLING (17)
menu heading, and the indicator will be “solid” to indicate the battery is regulated to the SET
FLOAT VOLTS DC setting from the BATTERY CHARGING (10) menu heading.
ERROR (RED)
Indicates that an operating error has occurred (refer to the ERROR CAUSES (5) menu heading
for a list of possible causes). To reset the inverter, press the red ON/OFF MENU button and then
select OFF and then ON with the SET POINTS buttons or by pressing the red button several
times.
This indicator will blink slowly to indicate that the AC source frequency is not well adjusted (3 to 7
hertz from nominal). You can use the LED blink to help adjust the AC source frequency. Once the
frequency is within 3 hertz of your nominal frequency, the LED will turn off.
OVERCURRENT (RED)
The load requirement has exceeded the inverter’s maximum output AC amps. A sustained
overcurrent condition will require a manual reset by pressing the red ON/OFF MENU button and
then selecting OFF and then ON with the SET POINTS buttons or by pressing the red button
several times. Momentary flashing of the red OVERCURRENT indicator means that the inverter has
reached it maximum output AC amps and has automatically reset itself. This may occur during
motor startups and is acceptable.
MENU BUTTONS
ON/OFF MENU BUTTON (RED)
Pressing the red ON/OFF MENU button at any time will take you directly to the SET INVERTER
menu item of the INVERTER MODE (1) menu heading. There are four options available from this
menu item. The first letter of the selected item will be underlined by the cursor. Pressing the SET
POINTS buttons will move the cursor either right or left.
GEN MENU BUTTON (GREEN)
Pressing the green GEN MENU button at any time will display the SET GENERATOR menu item
of the GENERATOR MODE (2) menu heading. There are four options available from this menu.
The first letter of the selected item will be underlined by the cursor. Pressing the SET POINTS
buttons will move the cursor either right or left.
MENU ACCESS/ADJUSTMENT BUTTONS (BLACK)
The MENU HEADING buttons are used to move either up or down through the selection of menu
headings. Once a menu heading is selected, the MENU ITEM buttons are used to move up or
down through the list of related menu items. The SET POINTS buttons change the value of a
parameter or select a mode, for the selected menu item.
