Table 6: Troubleshooting
Problem
Cause
Solution
Fault and Bypass indicators and
Diagnostic C indicator are illuminated
UPS dc/dc fault
UPS requires service. Contact your SolaHD
representative or SolaHD Technical Support for
assistance.
Fault indicator and Diagnostic D
indicator are illuminated
UPS PFC (Power Factor Correction
Circuit) fault
UPS requires service. Contact your SolaHD
representative or SolaHD Technical Support for
assistance.
Fault and Bypass indicators and
Diagnostic E indicator are illuminated
UPS inverter fault
UPS requires service. Contact SolaHD repre-
sentative or SolaHD Technical Support for
assistance.
Fault indicator and Diagnostic A and C
indicators are illuminated
UPS failed the battery test
replace the batteries. Contact your SolaHD
representative or SolaHD Technical Support for
replacement battery kits.
Fault and Bypass indicators and
Diagnostic C and E indicator are
illuminated
UPS shut down by a command from the
communication port(s)
UPS has received a signal or command from
the attached computer. if this was inadvertent,
ensure the communication cable used is
correct for your system. For assistance, contact
SolaHD Technical Support.
Fault indicator and Diagnostic A and B
indicators are illuminated; continuous
alarm sounds
UPS failure (includes dual-fan failure,
single-fan failure under certain condi-
tions, and battery charger failure)
Ensure fan is not blocked up. if the fault is not
resolved, contact SolaHD Technical Support for
assistance.
Ac Input indicator is flashing
UPS detected a line-to-neutral reversal
or a loss of proper grounding for the
UPS. A continuous alarm will sound; the
UPS cannot start up in standby status.
This is active only when power is first
applied to the input. Once the UPS is
running, the Ac input indicator will
flash, unless the input wiring is correctly
changed.
Contact a qualified electrician to verify site
wiring.
Battery indicator is flashing;
continuous alarm sounds
Battery source is not available
Check battery connections, completely power
down and restart the UPS.
NOTE:
if the battery circuit opens while the
UPS is running, it will be detected when the
next battery test is performed.
Bypass indicator is flashing
The bypass is disabled because the
voltage or frequency is outside the
acceptable limits.
The ac input powers the PFC input and serves
as the bypass source. if ac is present but the
voltage or frequency exceeds the acceptable
range for safe operation with a load, the
bypass will be disabled and this indicator will
flash, indicating that the bypass is unavailable.
