Keypad Security Options

A security code, PIN, can be set up to prevent unauthorised changes to the master station settings or
field unit outputs. Line two shows ' PIN Not In Use ' if no PIN has been set up and ' PIN In Use ' once a
PIN has been set.
The 'Access Level' number on line 3 indicates the operations that are protected by the PIN. The
meaning of these numbers is:
Access level:
1 - No protection. Setup can be changed and keypad commands entered without the PIN.
2 - Setup protection. Setup changes require the PIN but keypad commands do not.
3 - Setup and Command protection. Both setup changes and keypad commands require the PIN.
4 - No keypad commands permitted whilst any host serial communication line is active. [If all
serial communication links are inactive for 5 seconds then keypad commands can be entered
provided the PIN is entered (as with level 3).]
Commands available:
(All changes require either the Access level to be set to 1 or the current PIN to be entered)
