16 Profiler
This section covers the Profiler (or setpoint programmer) option. To confirm if profiling is
enabled on your controller, refer to the Service & Product Info menu (see page 67).
Introduction
The Profiler feature allows the user to store up to 255 profile segments, shared between a
maximum of 64 Profiles. Each profile controls the value of the setpoint over time; increasing,
decreasing or holding their values as required. The profile can control both setpoints if the 2
nd
control loop is fitted.
Profiler options and screens are added to the Main Menu and Operation Mode – See pages
63, 66 & 36.
Profiler Enabling
Controllers supplied without the Profiler option installed can be upgraded by purchasing a
licence code number. Refer to the Field Upgrade information on page 4.
To obtain the correct code you must tell your supplier the instrument serial number
– this can
be found in the Service & Product Info menu (see page 67).
To enter the licence code, hold down the L + D keys during the power-up splash screen.
Enter the 16-character licence code in the displayed screen and press R.
Profile Components
General profile configuration settings apply to all profiles. They enable or disable
“profile
editing while running
”, and automatic starting of the selected profile if it has been configured
with a delay or day & time start trigger.
If delay or day & time start triggers are disabled, profiles can only be manually started, and
this is with immediate effect even if they have a delay or day & time trigger defined.
If delay or day & time start triggers are enabled, delayed starts are possible, and if the
selected profile has a day & time trigger it will wait until the time set and before starting.
Note: Even if profile editing is enabled, changes to the current and next segment
or a running profile will not take effect until the profile is next run. Changes to
other segments will take effect immediately.
Profile Header & Segment Information
Each profile has its own header information plus 1 or more segments. The header
information is unique for each profile, it contains the profile
’s name; if it controls just one or
both loops; how it should start & stop; the abort & power-loss recovery actions; and how
many times it should be repeated.
Note: Profile Header information is only stored to memory as the Segment
creation sequence begins. No profile is created if you exit before this point.
Segment information is stored as each segment is created, but the profile
remains invalid until an end or join segment is defined.
Segments can be ramps, dwells, steps or special segments such as holds, ends, joins or
loop-backs.
