Algorithm Set Up Group
Introduction
This data deals with various algorithms in the controller and Timer
functions.
The Timer section allows you to configure a time-out period and to
select the timer start by either the keyboard ( RUN/HOLD key) or
Alarm 2. An optional digital input can also be configured to the start
the timer. The timer display is selectable as either “Time Remaining”
or “Elapsed Time”.
Alarm 1 is activated at the end of the time-out period. When the timer
is enabled, it has exclusive control of the alarm 1 relay—any previous
alarm 1 configuration is ignored. At time-out, the timer is ready to be
activated again by whatever action has been configured.
