Restoring Factory Defaults
To restore the unit to factory default settings, a special “CLEAN SWEEP” function is available through the
MX 9000 serial number screen. From the serial number screen, press and hold the
ENTER button for 3
seconds to reach the password screen. Enter “12356” using the DOWN – UP – SELECT buttons then
push ENTER . The “CLEAN SWEEP” screen will appear. This function can take up to 45 seconds to
complete – DO NOT TURN OFF OR INTERRUPT POWER DURING THIS OPERATION!
Performing a “CLEAN SWEEP” operation will erase
ALL
programmed information including K-factors,
linearizer tables and output limits programming. Current loop calibrations will also be set to default
values and will need to be reset. Use this function ONLY when all other troubleshooting methods have
failed and unstable operation of the controller remains. It is strongly suggested that the status screen
be viewed prior to performing a restore defaults to see if the raw data shown on it looks nominal to the
current process. Also make sure the K-Factor or linearizer table data is available for reprogramming as
these values will all be lost.
Warning!
