General Troubleshooting Guidelines

Shutdown / Restart Without Error Message
While inverting, the PROsine could shut down for a few seconds and then restart
inverting without reporting an error.
This has likely been caused by a reset of the internal microprocessor, which was
probably caused by a discharged and/or weak battery. In particular, this may occur
when the battery is weak and the unit is starting loads which demand a high surge
(e.g. air compressor, air conditioner, fridge).
You can try recharging the battery bank. If the problem persists, an equalize cycle
(only on batteries which permit equalization) may help. If this does not correct the
situation, the battery bank may require upgrading or replacement.
Resetting PROsine Operation
If the PROsine does not appear to be operating correctly it may require a system
reset to properly restart, this will clear any hysteresis (Chapter 5, “Operation”),
most errors and warnings (but these may recur if the condition that caused them
persists). Note that this will not change any configuration settings within the unit.
Locate the ON/OFF/REM switch on the PROsine, just below the connector for the
display panel. Set the switch to OFF for 5 seconds and then back to ON (or REM
if you are using a remote switch with the PROsine).
AC Bad Causes
If the input AC is not acceptable according to the configuration values you have
set, the AC Bad Cause screen in the Diagnostics menu indicates why. Specific
causes are listed in Table 6-1. You have the option of leaving the values or
changing them depending on your circumstances. If you want to change
configuration settings, see Configure PROsine—Advanced Menu on page 4–8.
Table 6-1 AC Bad Causes
AC Bad Cause Details
None There is no problem with the AC input.
Low Cycle V In The rms voltage as calculated over one cycle (0.016s) was less
than the user-set minimum acceptable operating voltage.
High Cycle V In The rms voltage as calculated over one cycle (0.016s) was
greater than the user-set maximum acceptable operating
voltage.
Low Average V In The rms voltage as calculated over 16 cycles (0.25s) was less
than the user-set minimum acceptable operating voltage.
Hi Average V In The rms voltage as calculated over 16 cycles (0.25s) was greater
than the user-set maximum acceptable operating voltage.
Low Frequency The frequency was less than the user-set minimum acceptable
operating frequency.
High Frequency The frequency was greater than the user-set maximum
acceptable operating frequency.
