Inverter Start/Stop/Shutdown Problems
SP PRO WILL NOT START
If the LEDs remain dark when the SP PRO is switched
on it is likely that DC power is not present. Check that
the main battery fuse is closed. Retry the procedure,
if it continues to fail contact your supplier for further
instructions.
If the SP PRO starts with the Shutdown led illuminated
check the reason in the Attention Required window in
the Now tab in Data View area of SP LINK, record the
fault code indicated and contact your supplier for further
instructions.
SP PRO SHUTS DOWN
Whenever the SP PRO shuts down, it attempts to restart
once per 15 minutes.
The SP PRO shuts down automatically for the following
conditions, which should be investigated:
• Overload
• DC over-voltage and under-voltage
• Excessive battery discharge
• Over-temperature
Check if the SP PRO front panel Shutdown LEDs indicate
a problem, and illuminated check the reason in the
Attention Required window in the Now tab in Data View
area of SP LINK, record the fault code indicated and
contact your supplier for further instructions.
AC POWER PROBLEMS
If the power fluctuates, lights go bright or dim but don’t
go out.
• Check the SP PRO front panel LEDs and
Performance data for information on the cause.
• The generator output may be varying due to poor
generator condition or switching on and off heavy
loads. Check the generator voltage reading via SP-
LINK.
• The SP PRO output may be varying due to switching
on and off heavy loads. Check the output voltage
reading (Inverter Load Voltage) via SP-LINK.
If the power goes off for short periods (1 second to a few
minutes)
• Check the SP PRO front panel LEDs and
Performance Data for information on the cause.
• The SP PRO may be in Power Save mode and
the load is too small to detect. In this mode
the SP PRO pulses the output until a load is
detected. Check the Econo Power Level in
SP LINK.
• The SP PRO may be shutting down due to
overload or low DC voltage and periodically
attempting restarts. If the SP PRO is shutting
down switch off any heavy loads that may
be causing the shut down. If the SP PRO is
shutting down due to low DC voltage, check
generator availability and reasons for the
generator not starting such as flat start battery
or no fuel
If the power goes off for longer periods (10 minutes to
many hours)
• Check the SP PRO front panel LEDs and
Performance Data for information on the cause.
• Check the Attention Required window in the Now
tab in Data View section of SP LINK to see if a fault
is indicated and contact your supplier for further
instructions.
