events.
The log cannot be reset
Following events are logged:
•
Warranty-affecting alarms (see
parameter 24-09 Fire Mode Alarm Handling
•
Fire mode activated

Fire mode deactivated
All other alarms occurring while fire mode is activated are logged as usual.
NOTICE
During fire mode-operation, all stop commands to the frequency converter are ignored, including coast/coast inverse
and external interlock. However, if Safe Torque Off is available in the frequency converter, this function is still active.
NOTICE
If using the live zero-function in fire mode, then it is also active for analog inputs other than that used for fire mode
setpoint/feedback. Should the feedback to any of those other analog inputs be lost, for example a cable is burned, live
zero-function operates. If this is not wanted, disable the live zero-function for those other inputs.
Set the wanted live zero-function in case of a missing signal when fire mode active in
Warning for live zero has a higher priority than the warning
Fire Mode
.
NOTICE
If setting the command
[11] Start Reversing
on a digital input terminal in
parameter 5-10 Terminal 18 Digital Input

frequency convertor understands this as a reversing command.
