4.24 Fire Mode Operation
This function is used to allow the inverter to ignore minor faults during emergency situations, such
as fire, and provides continuous operation to fire pumps.
When turned on, Fire mode forces the inverter to ignore all minor fault trips and repeat a Reset
and Restart for major fault trips, regardless of the restart trial count limit. The retry delay time set at
PRT-10 (Retry Delay) still applies while the inverter performs a Reset and Restart.

count increases by 1 at ADV-83 (Fire Mode Count) each time a Fire mode operation is run.
Fire mode operation may result in inverter malfunction. Note that Fire mode operation voids the
product warranty – the inverter is covered by the product warranty only when the Fire mode count is
