Fan start
After the fan starts, there is a delay and then the alarm flashlight flashes until the system pressure passes the
supervision level. The alarm flashlight can also flash during operation if the system pressure drops below the
supervision level.
• Write down the Fan Inverter supervision level in the space below and in the Installation and service manual:
________________(Pa) Supervision level
NOTE!
If the alarm flashlight continues to flash for approximately 30 seconds after Fan Inverter is started, or if
it flashes continually during operation, there is a problem, see
Chapter 12 Troubleshooting . To see if the
alarm flashlight is functional, stop and restart Fan Inverter. If the alarm flashlight is connected to Fan In-
verter, it does not flash if there is an input voltage interruption.
