2704 Controller Access Levels
If a passcode of ‘None’ has been entered for any level it will not be necessary to enter a
passcode to enter that level.
The levels of access covered by this manual are Levels 1, 2, 3 and View Config. In any of
these levels the controller continues to monitor and control the process to which it is
connected. This allows parameter values to be altered to suit the operating conditions of the
process.
Configuration of the controller allows the fundamental characteristics of the controller to be
changed and for this reason it enters a standby state in which all outputs are frozen. In this
condition the instrument no longer controls the process to which it is connected.
