Unexplained Faults
Sometimes the PROsine may not show a fault at the panel, but may be acting in an
unexplained way.

Error Details
Shorepower is present but the PROsine
will not transfer The voltage or frequency of the shorepower is not within the transfer
limits configure in the PROsine under the Configure PROsine —
Advanced menu. To view the shorepower quality set the DISPLAY
switch to ON and select the AC In screen. If desired, you can switch to
Configure mode and alter the transfer limits to accept the shorepower but
some loads may be damaged if the shorepower deviates too far from the
standard values. The factory settings are safe. Otherwise, the shorepower
is not acceptable and you may need to consult an electrician or check with
the manager of the facility providing the shorepower.
Shorepower quality is within the
transfer settings but the PROsine is still
not transferring. This may be due to hysteresis. See “Hysteresis” on page 5–3, for details.
The PROsine stopped inverting due to
low battery voltage and will not restart
even though battery voltage is above
the shotdown level and the "Auto
Restart After Error" has been set See “Hysteresis” on page 5–3. If the PROsine shuts down due to low
battery voltage then it will not restart until the battery voltage exceeds
12.5Vdc.
The PROsine sometimes will not start
inverting, or may stop inverting and
report no error or unusual errors Check battery condition and wiring. It is important to have battery wiring
that is of the correct size as the unit may require up to 600A to start heavy
loads. See Chapter 3, “Installation”, for details.
PROsine not providing rated charge
current The battery charging current can be limited for a number of reasons:
Small battery bank size. To avoid damaging the batteries the PROsine
will generally charge in the FLOAT or ABSORPTION stages at only 25-
30% (in Amps) of the configured battery bank capacity (in A-hr) - this
varies with the battery type configured in the PROsine.
Battery does not accept full current due to being partially charged or
damaged.
Other AC loads are present on the PROsine output and the unit is reducing
the charging current so that the total AC input is kept below 80% of the
AC Breaker Size setting (per UL and CSA requirements). Or the AC
Breaker Size has been configured to a low value to limit the charging
current so the PROsine can charge batteries from a weak AC source. With
no additional AC output loads this breaker setting must be 19A or greater
so that the PROsine can draw 15Aac to provide 100A of battery current.
The PROsine internal temperature is high. To avoid overheating the
PROsine will reduce the allowable charging current if one of the internal
temperatures exceeds 75°C.
