05G Input Relay
Failure
The AC transfer relay is
bad or an AC source was
wired directly to the AC
output.
Disconnect the inverter’s output wiring. If error
continues, have unit serviced.
05H Gen Failed To
Start
Indicates that six “auto
generator start attempts”
have occurred without
successfully starting the
generator.
Voltage has not reached
80 Vac during the
25D Max Cranking
Seconds period.
Voltage did not maintain
greater than 80 Vac for
the majority of time while
the inverter was charging.
Reset the auto-generator control system by selecting
OFF at the 02A Generator menu.
Verify that when the generator is running (manually
started) that there is voltage on the AC2 input
terminals inside the inverter’s AC access door.
If you do not have an automatic start generator that is
started by the inverter, leave it in the OFF selection.
If you do have an automatic start generator that is
started by the inverter, test by selecting ON.
Measure the AC voltage on the AC2 input terminals
while the generator is starting. Check the setting at
25D Max Cranking Seconds. Tune up generator if
necessary.
Measure AC voltage on the AC2 input terminals
while generator is running. Check for poor
connections or too small of wires between the
generator and inverter. Tune up generator if
necessary.
05I Gen Stopped Due
To V/F
The generator was
running but was not
operating within the
voltage or frequency
tolerances and was not
able to connect.
Check the generator’s output voltage and frequency.
Ensure that 13C Input Upper Limit VAC and
13D Input Lower Limit VAC are set correctly.
Error LED is flashing and
there is no error under 05
Error Causes Menu.
AC source frequency is
just out of tolerance
(53 to 57 Hz or 63 to
67 Hz).
No problem with AC source or inverter. The error
LED is a visual indicator to fine tune your AC
frequency. This error does not affect operation.
