Alarm Descriptions
All rectifiers report ac supply failure or a digital input with Function set to "AC Fail"
is active.
Phase 1/2/3 of the ac input, as measured by CR48-3G rectifiers, has failed,
i.e. it deviates from the Nominal AC Voltage by more than the AC Phase Fail
Threshold. Not available in systems with other rectifier models.
Phase 1/2/3 of the ac input, as measured by CR48-3G rectifiers, deviates
from the Nominal AC Voltage by more than the AC Phase Voltage Threshold.
Not available in systems with other rectifier models.
The ac distribution cooling system or fan controller has failed (indicated by an active
digital input with Function set to "ACD Fan Fail".
An I/O board has an analog input with Function User Defined and the input is either
out of range or unavailable.
Battery Current Limit (BCL) is active. See Battery Current Limit on page 23.
A battery fuse has blown or a battery disconnect device has operated (indicated by
an active digital input with Function "Battery Fuse Fail").
The analog input with Function set to "Battery Temperature" has a value above the
Battery Temperature High Threshold.
This alarm indicates either thermal runaway of the batteries or that the batteries are
operating at a temperature that may cause reduced battery life.
The analog input with Function set to "Battery Temperature" has a value below the
Battery Temperature Low Threshold.
This alarm indicates a risk to the standby power system battery as lower
temperatures reduce the battery capacity.
The Battery Test control process is active. See Battery Test on page 25.
The batteries do not have the required capacity or are not fully charged. See Battery
Test on page 25.
A cabinet fan has failed (indicated by an active digital input with Function set to
"Cabinet Fan Fail").
One of the following is true:
The Rectifier Current Limit is set higher than the Maximum Current Limit of all
the registered rectifiers. See details on page 33.
The OVSD Set Point is out of the range of any registered rectifiers. See details on
page 33.
More than one digital output are mapped to the same relay on an I/O board or
SiteSure-3G Module. See details on page 75.
An LVD contactor is in Conflict state. See details on page 42.
Smart Alarm Based Disconnect is Enabled, but the corresponding Smart Alarm is
Disabled. See details on page 42.
A Smart Alarm source has an invalid Source Triggered setting.
A digital output is set to manual control (control state is set to Active or Inactive). See
Digital Outputs on page 75.
The Equalize control process is active. See Equalize on page 26.
The Fast Charge control process is active. See Fast Charge on page 27.
