Front Panel Security Lockout
To prevent accidental changes to settings, the MLC features a front panel security lockout mode for disabling access to controls. When front panel lockout is enabled, all the front panel buttons are disabled. If a button is pressed, all the buttons flash rapidly three times to indicate lockout, but no action occurs.
You can lock and unlock the front panel by the following methods:
•Front panel buttons
•The MLC configuration software (see the MLC 60 Series Configuration Program Help File).
•SIS commands (see the Front panel lockout commands in the “SIS Control” section).
Locking Using the Front Panel Buttons
To lock the front panel using the buttons, press and hold the On and Off (top two) buttons simultaneously for 3 seconds. All the front panel buttons and the red Activity LED flash three times rapidly.
To unlock the front panel, press and hold the On and Off buttons again for 3 seconds. All front panel buttons flash three times slowly while the Activity LED blinks green three times.
