Inverter Settings
PS0 The inverter is disabled. The AC Output terminals are getting power
from the utility (AC input) only. When utility power is not available,
the unit will not provide an AC backup function from the inverter and
the display will automatically turn off in approximately 10 seconds.
When the Power button is pressed again, the display will turn on for
another 10 seconds.
To enable the inverter or to turn on the backup function, the PS0
setting has to be changed to a different setting.
PS1 The inverter is in By-Pass mode with Search mode set to OFF. The
unit will provide an AC backup function when utility power is not
available.
PS2 The inverter is in Standby mode with Search mode set to ON. The
unit will provide a continuous backup function only when utility
power is unavailable AND the connected output load is >10W. Once
it is on, the unit will automatically return to Search mode and turn
off when the connected AC load drops to <3W.
Note:
During Search mode, the inverter
turns on every few seconds
for a few AC cycles to check on the 10W power consumption.
PS3 Not used.
PS4 Performs same function as PS1. The Power button can be used to
turn AC output on and off, even with AC input power being present
in By-Pass mode.
When the unit is turned off in By-Pass mode using the Power button,
the display will continue to show battery voltage and the Status LED
will turn off.
