Xantrex Technology PROsine 2.0 user manual Shutdown / Restart Without Error Message, AC Bad Causes

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 6-1AC 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.
