Troubleshooting
Errors and Alarms
The RMF Controller requires two critical inputs to operate effectively and safely. Without a
minimum of 50 PSI of air pressure and a positive signal from the motor starter that the pump is
running, the RMF Controller will return to idle mode and display an alarm in red at the top of the
screen. When the cause of the alarm is identified and corrected press the ALARM icon to
display active alarms, and then press the RESET ALARM icon to clear all active alarms. Normal
operation of filter can now resume.
