•
INVERTER FAIL INV SHUTDOWN –
inverter has shutdown due to inverter
output voltage below tolerances.
•
BYPASS ON INV SHUTDOWN –
inverter has shutdown because the
bypass breaker has been activated while the inverter is supplying power to
the load.
•
HIGH DC BUSS INV SHUTDOWN –
inverter has shutdown because the DC
Bus voltage is outside of operating parameters while the inverter is
operating.
•
INV OVERLOAD INV SHUTDOWN –
inverter has shutdown because an
overload condition has been detected on the output. The inverter will
automatically restart after the condition has been removed for a period of
seven seconds.
•
70% LOAD –
load connected to the output is over 70% of the UPS rating.
•
110% LOAD -
load connected to the output is over 110% of the UPS rating.
•
125% LOAD -
load connected to the output is over 125% of the UPS rating.
•
150% LOAD -
load connected to the output is over 150% of the UPS rating.
•
RESERVE AC FAIL –
supply voltage to the Reserve is outside of operating
window.
•
RESERVE FREQ FAIL –
supply frequency to the Reserve is outside of
operating window.
•
BATTERY LOW –
the DC bus (or battery) voltage is lower than 320VDC.
Low battery shutdown is approaching.
•
BATTERY LOW SHUTDOWN –
the inverter has shutdown because the DC
bus (or battery) voltage is below operating level (lower than 295VDC).
•
RECTIFIER AC FAIL –
supply to rectifier is outside of operating window.
•
ROTATION ERROR –
supply phase rotation is outside of operating
window.
•
RECTIFIER SHUTDOWN –
the rectifier has shutdown because the DC bus
voltage has exceeded maximum operating level (over 445VDC). The rectifier
will automatically restart 30 seconds this abnormal condition has been
cleared.
•
RECTIFIER HIGH DC –
the DC voltage has exceeded maximum operating
level (over 430VDC). The bus voltage is limited to this voltage.
•
BOOST CHARGE –
the batteries are being boost charged by the rectifier.
•
BATTERY TEST –
batteries are being tested.
•
EMERGENCY STOP –
the inverter has shutdown because the emergency
stop switch has been activated.
•
COMM. ACTIVE –
blinks when data is being transmitted or received via the
communication port.
