Setting: '0' = Disabled, '1' = Enabled.
*** The "Lockout Disable Key" needs to be inserted into the TTL I/O connector to display this setting***
When enabled, the "Lockout Disable Key" needs to be inserted into the TTL I/O connector to change any
of the pump's settings. When the key is removed, the user can only start or stop the pump and review
current settings. Settings can still be changed from RS-232. When the user attempts to change a setting,
the message
will be displayed.
Auto-Run Mode: When used in conjuction with the Program Select programming function as Phase 1, the
pump will enter Auto-Run Mode. In this mode, on power up, the Pumping Program will immediately
begin to execute and the user would be prompted to enter a dispensing program number.
