FanMaster Alarms An alarm banner displays on the PanelView terminal to indicate an alarm
condition. The alarm banner displays on the screen until “Ack”
(Acknowledge) is pressed. Clearing the alarm banner does not remove the
alarm condition. Refer to the table below for a complete list of alarms and
possible actions.
Note: If after investigation, sensor problems persist, you may switch
FanMaster to override mode by setting the FanMaster Override switch on
the front of the FanMaster enclosure to “ON”. This allows FanMaster to run
at 100% speed whenever the original HVAC controls call for the fan to run.
Also, If the drive has faulted and the fault cannot be cleared, and if the
installed drive is equipped with a bypass switch, it can be used to bypass the
drive and use a bypass starter to run the fan.
