FIRE MODE FUNCTION (IFD SW only)
When the digital input set as Fire Mode is activated, any protection feature of the inverter is ignored, so that no alarm
trips.
CAUTION
The Fire Mode function must be used only when strictly necessary in order to
safeguard people’s safety (e.g. applications for fire pumps).
It must not be used to prevent alarms from tripping in standard domestic or industrial
applications.
When operating in Fire Mode, the inverter:
-
exploits the frequency reference set with P38;
-
exploits 10-second UP and DOWN ramps (that cannot be altered);
-
can activate the digital output (if any) set with parameters P60, P61, P62;
-
ignores the following alarms:
o
A11 Bypass Circuit Failure
o
A18 Fan Fault Overtemperature
o
A18 Second Sensor Overtemperature
o
A20 Inverter Overload
o
A21 Heatsink Overheated
o
A22 Motor Overheated
o
A25 Mains Loss
o
A36 External Failure
o
A40 Serial Communication Error
-
activates an infinite number of AutoReset functions for the following alarms: Overcurrent, DC Overvoltage,
DC Undervoltage.
CAUTION
If an asterisk (*) appears next to INVERTER OK on the display, the product guarantee is
no longer valid.
The asterisk appears if at least one condition requiring the activation of a protection
feature occurs when the inverter is running in Fire Mode.
