18. ALARM HANDLING
When a malfunctioning occurs, the driver has two possible behaviors depending on the cause of the alarm:
BLOCKING
The cause of the alarm is very dangerous -> The driver stops immediately. To restart the fan,
once the problem has been corrected, it is necessary to reset the fan or power the driver off
for 5 minutes.
AUTO-RESTARTING
The cause of the alarm is contingent to a wrong setting or wrong working condition. The
alarm indications are activated, but after some seconds the fan tries to restart automatically.
The alarms can be monitored through three different ways:
• Modbus Registers
• Blinking LED
• Digital Output
