Status Word 1 Status Bit Condition Definitions
The definitions of the conditions and usage of the bits in Status Word 1 are defined below.
Over Temperature (Status Word 1, Bit 0)
The Over Temperature status bit indicates that the thermostat internal to the GUPS 2400A-107
has exceeded its trip point. A binary value of 0 indicates normal operation, while a binary value
1 indicates that the thermostat sensor has exceeded its trip point value of 95ºC.
Alarm Sense (Status Word 1, Bit 1)
The Alarm Sense bit indicates that an alarm condition is currently being detected by the unit. A
binary value of 0 indicates that no alarms are being sensed, while a binary value of 1 indicates
that an alarm is being sensed.
Alarm Silence (Status Word 1, Bit 2)
The Alarm Silence bit reflects the setting of the front panel Alarm Silence button of the GUPS
2400A-107. A binary value of 0 indicates that the Alarm Silence is Not Enabled (when an alarm
condition is sensed the audible alarm will annunciate it), while a binary value of 1 indicates that
the Alarm Silence is Enabled (a subsequent change in the alarm condition will re-enable the
alarm).
Charger Status (Status Word 1, Bit 3)
The Charger Status bit reflects the condition of the charger enabled logic of the GUPS
2400A-107. A binary value of 0 indicates that the charger is not on, while a binary value of 1
indicates that the charger is on.
Current Overload (Status Word 1, Bit 4)
The Current Overload bit indicates that the unit has sensed a current overload of greater than
105% of the specified output current. A binary value of 0 indicates normal operation, while a
binary value of 1 indicates that the output current is greater than 105% of the specified current
output capability of the unit.
Battery Switch (Status Word 1, Bit 5)
The Battery Switch bit reflects the status of the SCR battery switch in the GUPS 2400A-107
which connects the battery to the internal DC bus. A binary value of 0 indicates that the battery
switch is not on, while a binary value of 1 indicates that the battery switch is on.
Test Mode (Status Word 1, Bit 6)
The Test Mode status bit indicates if the GUPS 2400A-107 is in test mode. A binary value of 0
indicates that the unit is in normal operating mode, while a binary value of 1 indicates that the
unit is in test mode (as commanded by the execute test mode button on the front panel of the
GUPS 2400A-107).
Inverter Status (Status Word 1, Bit 7)
The Inverter Status bit indicates the operating condition of the output inverter of the GUPS
2400A-107. A binary value of 0 indicates that the output inverter is not on, while a binary value
of 1 indicates that the inverter is on.
