The fire Mode function is activated by using one of the external multifunction inputs S1 to S6 and
setting the relevant parameter for the selected input by 03-00~03-05 =【28】
Fire mode can also be enabled by setting the functions of S1 to S6 by communication method.
Once Fire Mode is activated following takes place:-
1. The operator panel indicates FIrE, and the FIrE will be recorded in inverter fault log.
2. The inverter will run at full speed up to the maximum of inverter running frequency as set in 00-12,
unless the main power is lost or cut off or the inverter itself breaks down.
3. When Fire Mode is activated, all protectional functions and alarms, such as ES, BB, OV, OC etc, will
be ignored. STOP key on the operator panel becomes ineffective.
4. To reset fire mode: turn power off, remove fire mode input signal, and power on.
