FAN1 External Fuse Minor
A resistive battery potential is present on the FAN
alarm input at TB3-6 or Millennium BSL-65,
indicating a minor fuse alarm is active in the plant
circuit connected to this point. Typically only the
capacitor charge circuit fuse alarm is wired here as
a minor fuse alarm
HCL1 History Cleared
A user has cleared the event history record of one
of Galaxy’s history reports. This is a latched
event, remaining active until cleared by a user.
HFV1 High Float Voltage
Plant voltage is above the programmed threshold
for this alarm. The HFV threshold should be set
lower than the HVA threshold which causes a
HVSD signal to be issued to plant rectifiers.
HPA1 Half Power Reserved for future application.
HVA1 High Voltage
Plant voltage is above the programmed threshold
for this alarm. The HVA alarm causes a HVSD
signal to be issued to plant rectifiers.
LCA1 Low Current
A connected rectifier has load share enabled, but
its present output load is less than a predefined
threshold for that rectifier type. (Usually 3% or
less of capacity.)
LMR1 Limited Recharge
The plant load has exceeded the programmed
percentage of the total rectifier capacity set for
this alarm. Rectifier capacity may be inadequate
for recharging batteries in an acceptable period of
time following an extended battery discharge.
This is a latched event, remaining active until
cleared by a user.
LSF1 Load Share Fuse
The fuse protecting the load share bus has
operated on the control card of a connected
rectifier.
LVD1 Low Voltage Disconnect
An externally controlled LVD is open, providing a
closure signal to Galaxy between TB3-37/-38 or
Millennium BSL-61/-62 for alarm purposes.
LVDA1 Low Voltage Disconnect Fail
The monitoring circuit of an external LVD has
failed, providing a resistive battery potential
signal into Galaxy TB3-16 or Millennium
BSL-84.
