LOW BATT / THERM BUZZER:
ON/OFF SWITCH:
OVER VOLTAGE PROTECTION:
UNDER VOLTAGE PROTECTION:
OVER TEMPERATURE PROTECTION:
Produces an audible alarm if
DC input voltage falls to a level within 2% to 4% of the low limit
of inverter, or, if there is an over temperature condition.
Located on front panel; turns the inverter on
and off.
When input voltage to the
inverter exceeds set limits, the inverter will immediately and
without warning shut off. When input voltage returns to normal
range, the inverter will immediately restart. Since high over
voltages tend to have very fast edges, the inverter must shut
down quickly to protect itself. This kind of fault usually occurs if
the battery is suddenly disconnected from the system and the
battery charger continues to supply current.
When battery voltage falls to
within2%to4%oflowlinevoltageinXP-600andXP-1100units,
and with in 5% of low line voltage in XP-2000 units, the LOW
BAT/THERM buzzer will sound. If the condition continues without
reducing load to the inverter or adding charge to the battery, the
inverter will shut off. When voltage rises to approximately 95% of
nominal battery voltage in XP-600 and XP-1100, and 90% of
nominal battery voltage in XP-2000 the inverter will turn back on
and the alarm condition will clear. The inverter can be manually
reset by cycling the on/off switch. This will reset the protection
circuit and turn the inverter on at any voltage above minimum
voltage.
The inverter is also
protected against overheating. It will provide its full rated output
up to the temperature listed in the specification sheet. If it is
subjected to higher ambient temperatures or air circulation is
blocked, the inverter may overheat. If the LOWBATT/THERM
buzzer sounds, immediate action is required or the inverter will
shut down. Either reduce load, or provide more cooling in the
immediate environment. If no action is taken, the inverter will
likely shut down within 2 minutes. When the inverter shuts down,
the alarm condition will persist and the cooling fan will continue
to run. Since the inverter has eliminated its load, it will cool fairly
