SYSTEM POWER SWITCH - The main control switch
that engages utility power to the entire unit. By
activating this switch it initializes normal operation.
INPUT AC LINE FUSE - The input line protection
device to limit excessive current draw to the system.
AC In - The utility input indicator that identifies status
of the line voltage. If the line voltage is within the
specified range, it will remain lit. If the AC input is out
of range, this indicator will flash in 1 to 2 second
intervals.
Cold Start - A momentary push-button switch to
activate the system in the event no utility power is
available. The system will be allowed to start up by
using power from its internal battery. Depress this
switch, the indicator above it will light, and hold it in
until the audible alarm beeps once. The system will
maintain a load depending upon the condition of the
battery. The system power switch must be in the
ON
position.
Inverter - This indicator identifies the status of the
regenerated, conditioned protected output power. This
indicator will stay
ON as long as protected power is
available from the power inverter generator.
Load I - A momentary push-button switch that toggles
the output LOAD I AC output outlets at the rear panel.
Unless the unit is powered up using the Cold Start
switch, the output load will normally be connected to
the inverter generator output. The indicator above the
switch will be
ON to represent this. The output can be
disconnected by depressing the switch. While the
switch is depressed, the indicator will blink to represent
transition. Once the indicator stops blinking, the switch
can be released for a successful transition.
Load II - A momentary push-button switch that works
identical to LOAD I except it corresponds to the LOAD
II AC output receptacles at the rear panel.
Load Level - This is the system output capacity status
bar. The number of lights on the graph indicate an
approximate percentage of system full load. All lights
being
ON would indicate full load.
Alarm Silent/Test - A momentary push-button switch
that controls two different functions depending on the
mode of operation. In the normal mode of operation, if
this switch is depressed and held in, the above
indicator will blink. While blinking, the unit will perform
an internal 1 to 2 minute battery check. Once the test
is completed, if the battery is below standards, the
system will indicate that the battery needs replacing.
The system will not run this battery test unless the
battery is detected to be fully charged.
During battery or abnormal operation, an audible alarm
will accompany this mode. By depressing this switch,
the adjacent indicator will blink. When it stops blinking,
the alarm will be silenced. Once the fault or reason for
the alarm is corrected, this audible alarm condition will
automatically reset. The audible alarm can be re-
enabled during abnormal conditions by pressing and
holding the switch again.
Alarm - This is a fault indicator that will light in the
event that the inverter generator is non-operable. This
could be due to an overtemperature situation or an
inverter malfunction.
Battery Level - This is the battery status bar graph.
During normal operation, this bar graph will show the
charging of the battery; all indicators lit will represent a
fully charged battery. During battery operation, this bar
graph represents a discharge meter indicating less
battery time available as each light goes
OFF. The last
red LED indicates a Low Battery.
NOTE - All switches must be held in for at least two
seconds to engage their function. This is to prevent
any inadvertent switch operation.
INPUT – An inlet that accepts the six foot power cord
used to supply utility power to the system.
DC INPUT - The auxiliary battery input connector to
add optional batteries for extended backup time.
120VAC OUTPUT (Load I & Load II) - The output
groupings that can be independently controlled by the
corresponding front panel switch. During normal
operation, inverter generator power is supplied at
these outlets.
120VAC OUTPUT (Unswitched) – The output that is
not independently controlled and always provides
inverter generator output power.
SIGNAL - A DB-9 subminiature, female connector that
outputs the open-collector signal contacts that
generate a low state during utility interrupt, low battery
and inverter off conditions.
RS232 - A DB-9 subminiature, female connector that
outputs true RS232 communications signals.
IDENTIFICATION LABEL - The model number and
serial number of the system is located on the side of
the unit. Always refer to this information when
corresponding with the factory.
VOLTAGE SELECTOR SWITCH - Allows operation
with 220 or 120 VAC as the input voltage source.
Never operate unit with 220VAC in
if this switch is in the 120VAC
position.
