1.1 TAILORING THE CONTROLLER TO SUIT YOUR NEEDS
The Controller has three modes in which adjustments can be made via the front
panel keys:
Configuration Mode: This is normally used only when the Controller is
first configured or when a major change is to be made to the
Controller characteristics. Entry into this Mode is security-protected.
The Configuration Mode parameters should be set as required
before any other adjustments are made. Changing Configuration
Mode parameters invariably sets other parameters to their default
values. Adjustments to these parameters should be performed only
by personnel competent and authorised to do so.
Set Up Mode: This mode is used when a change to the process
set-up is required. The frequency of use for this mode is dependent
upon the process being controlled. This mode also determines the
scope of adjustments available in Operator Mode (see below).
Access to this mode is via a user-defined password.
