MXI1503-2004 CONTROL UNIT
PUB13-09 Rev 1 4
If this status LED is not lit, then the operator should then check the INTK submenu to determine the source of the
problem. Note that the same individual interlock status can be found on the other submenus as well, but the INTK
submenu is a place where all the individual interlocks are displayed in one place.
2.1.6 REM Status LED
Remote Status for the remote controls, operator controlled via the REM submenu.
Lit when the system is in REMOTE mode and enables remote commands.
Not lit when in LOCAL mode and remote commands are disabled.
2.1.7 ERR Status LED
Status that shows an error either is current or has occurred since last check. This is a composite of the other status
and is a general indication that something is wrong. One of the error conditions is VSWR Trip, which is a saved status.
The VSWR Trip indicates that a VSWR condition had occurred (but may no longer be present). The operator must
press the front panel reset button (or issue a reset command remotely) to clear the VSWR Trip condition.
The user should check the AMP screens and the Interlock screen to check the source of the error.
Lit when both Amps are communicating, Ext1 is closed, VSWR Trip and VSWR Lockout are not present.
Not lit if either Amp is not communicating, Ext1 is open, VSWR Trip or VSWR Lockout have occurred.
2.1.8 SubMenu Select Buttons
The fourth line of the LCD holds select buttons that will cause the LCD to jump to different submenu screen that
provides more detailed information on a certain aspect of the MXi operations. Each submenu screen has an ‘OUT’
button that allows the user to return to this main screen.
