Generator Fail
Generator Control is active but the SC200 has not detected that the ac supply is
present (rectifiers have not turned on) after the Generator Fail Alarm Recognition
Period .
High Float
The bus voltage is above its normal range (set by the High Float Threshold ).
High Load The bus voltage is higher than the safe range for the load and/or battery (set by the
High Load Threshold ).
In Discharge Battery Charge State is Discharge (see details on page 56 ).
Load Fuse Fail
A load fuse has blown or a load disconnect device has operated (indicated by an
active digital input with
Function "Load Fuse Fail").
Low Float The bus voltage is below its normal range (set by the Low Float Threshold ).
Low Load
The bus voltage is lower than the safe range for the load and/or battery (set by the
Low Load Threshold ).
LVD Characterization Error An LVD contactor must be characterized. See Low Voltage Disconnect on page
38 .
LVD Disconnected An LVD contactor has disconnected the battery or load. See Low Voltage Disconnect
on page
38 .
LVD Fail
An LVD contactor is faulty or the control cable from the I/O board is disconnected.
See Low Voltage Disconnect on page
38 .
LVD Manual An LVD is set to MANUAL CONNECT or MANUAL DISCONNECT. See Low
Voltage Disconnect on page
38 .
Missing Hardware The SC200 has lost communication with a mapped I/O board or SiteSure-3G
module. Or, an input or output is mapped to an invalid I/O board or SiteSure-3G
module. See I/O Board Mapping on page
119 .
MOV Fail One or more MOV cartridges have failed and must be replaced (indicated by an
active digital input with
Function set to "MOV Fail").
Multiple Rectifier
Comms Lost
More than one rectifier has lost communications. See also Rectifier Comms Lost on
page
110 .
Multiple Rectifier Fail
Multiple rectifiers are faulty or their ac supply has failed without causing partial or
total ac supply failure.
Inhibited by: AC Fail and Partial AC Fail (if no more than one rectifier has failed
while still detecting the AC supply). See details of Alarm Inhibiting on page 47 .
Partial AC Fail
A digital input with Function set to "Phase Fail" is active, or more than 20% of single-
phase rectifiers are reporting ac supply failure, or all 3-phase rectifiers are reporting
loss of the same phase.
Inhibited by: AC Fail . See details of Alarm Inhibiting on page 47 .
Rectifier Comms Lost Normally this alarm indicates that a rectifier has been removed during routine
maintenance. However, faulty rectifier communications or losing the rectifier
communications bus can also trigger this alarm. If removing multiple rectifiers
triggers this alarm, reset it from the keypad before it triggers an external alarm.
Inhibited by: Multiple Rectifier Comms Lost . See details of Alarm Inhibiting on page
47 .
Rectifier Current Limit Rectifier(s) in current limit.
Rectifier Fail A rectifier is faulty or its ac supply has failed without causing partial or total ac
supply failure.
Inhibited by: Multiple Rectifier Fail , AC Fail and Partial AC Fail (if no rectifiers have
failed while still detecting the AC supply). See details of Alarm Inhibiting on page
47 .
