Step Logic, Basic Logic and Timer/
Counter Functions
Four Bulletin 284 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.
