Step Logic, Basic Logic and Timer/Counter
Functions
Four Bulletin 284G ArmorStart® logic functions provide the capability to
program simple logic functions without a separate controller.
• Step Logic Function
Steps through up to eight preset speeds based on programmed logic.
Programmed logic can include conditions that need to be met from
digital inputs programmed as Logic In1 and Logic In2 before stepping
from one preset speed to the next. A timer is available for each of the
eight steps and is used to program a time delay before stepping from
one preset speed to the next. The status of a digital output can also be
controlled based on the step being executed.
• Basic Logic Function
Up to two digital inputs can be programmed as Logic In1 and/or Logic
In2. A digital output can be programmed to change state based on the
condition of one or both inputs based on basic logic functions such as
AND, OR, NOR. The basic logic functions can be used with or
without step logic.
• Timer Function
A digital input can be programmed for Timer Start. A digital output
can be programmed as a Timer Out with an output level programmed
to the desired time. When the timer reaches the time programmed into
the output level the output will change state. The timer can be reset via
a digital input programmed as Reset Timer.
• Counter Function
A digital input can be programmed for Counter In. A digital output can
be programmed as Counter Out with an output level programmed to
the desired number of counts. When the counter reaches the count
programmed into the output level the output will change state. The
counter can be reset via a digital input programmed as Reset Counter.
