Two indicators are provided and identified as "STATUS". One
indicator is labeled "BYPASS", the other "INVERTER". In
normal condition, if the OFF-LINE (bypass) mode has been
selected, the "BYPASS" LED will glow continuously and the
"INVERTER" LED will blink ON and OFF. If the ON-LINE
(inverter) mode has been selected, the "INVERTER" LED will
glow continuously, the "BYPASS" LED will blink. Blink rate is
one second on, one second off.
GREEN -- Utility voltage and frequency within tolerance.
YELLOW -- Warning! Utility voltage or frequency not in
tolerance.
RED -- Alert! Bypass abnormal. Utility voltage or frequency
either too low or too high, can not transfer to bypass.
NOT ILLUMINATED -- Bypass not available.
GREEN -- Inverter ON, no warnings or faults.
YELLOW -- Warning! -- Inverter overload or overload
recovery cycle, thermal warning, or DC warning.
-- Bypass abnormal.
RED -- Alert! Inverter not operating. Stopped for abnormal
Inverter, overload, short circuit, thermal warning, DC
warning, or DC circuit breaker OFF.
At power up or software recovery, an automatic lamp test
sequence will be automatically initiated. Both indicators will
simultaneously go through a RED-YELLOW-GREEN lamp
test sequence.
