RAM Error
The MX processor continually checks RAM for memory corruption errors. If corruption is detected, the processor will
force a reset to clear RAM. The LCD will temporarily display the following prior to this reset:
“XXX% OPEN”
“RAM ERROR”
After the reset, the display will read normally. Any momentary commands (DDC command, momentary pushbutton,
etc.) that were not completely executed must be reissued.
ROM Error
The MX processor continually checks EPROM for memory corruption errors. If corruption is detected, operation is
disabled. If the selector switch is in “LOCAL” or “REMOTE,” the LCD will display the following:
“XXX% OPEN”
“ROM ERROR”
When the selector is placed in “STOP,” the unit will require reinitialization and the LCD will display the following dialog:
