Automation Interface
EC Motor

Application

The EVO/ECM-ACU+ allows industry standard 0V to
+10V automation signals to adjust and monitor EC
Motors. These are fractional horsepower air moving
motors featuring an internal microprocessor based
drive. The design provides exceptional efficiency,
performance and motor life. The motor may be
factory configured to provide constant mass airflow
or constant torque over the configured control range.
The ACU+ provides remote adjustment of the motor
output from 0 to 100% of the motor's programmed
control range. A signal lamp on the control
continuously flashes out the flow index
are not required to read the flow index. A 0V - +10V
signal connects RPM to the automation control.
Jumpers allow the ACU+ to be configured for 0V to
+10V automation signal, +2V to +10V automation
signal, and manual/override control. The ACU+ can
also be used for stand-alone manual control.
Signal Lamp
The green lamp continuously indicates the flow
index. After a pause, the lamp flashes out the tens
digit, then the units digit of a number between 1 and
99. Long flashes represent the tens digit, and short
flashes represent the units digit. For example, a
flow index of 23 flashes two longs, then three shorts.
Two extra long flashes indicate a flow index of 0. An
extra long flash and ten short flashes indicates a
flow index of 100. The lamp flashes the signal that
was present when the flash sequence started.
Turning Adjust controls the EC motor to the
manually adjusted setting. The manual setting has
authority for 15 minutes.

Manual Override

•
Temporary local Adjust for air balance.
•
Manual control without any 0 - +10V signal.
•
Local Default
•
Startup mode keeps control in Manual until
automation is connected.
When local adjust is turned, Vspd is set by Adjust.
Vspd remains at the Adjust value for 15 minutes
after the last Adjust movement is detected allowing
time to make airflow measurements.
With the "M" jumper in place, Adjust controls the
motor when a +0.1-+10V control is not detected.
This feature allows the ACU+ to be used as a
manual control. And it provides a local default for
critical applications by providing a safe operating
speed should the +0.1-+10V signal fail.
The ACU+ is provided new with startup mode
enabled. The control behaves like the "M" jumper is
in place, even if it is not. This allows the mechanical
equipment to be tested and used before automation
is installed. After automation is installed, the startup
mode can be disabled by starting/stopping the motor
five times with a +0.1-+10V signal present. The
motor start/stop event may be performed by cycling
2
~24V power to the control with the control signal
above +0.1V, or by raising and lowering the +0.1 -
+10V signal with the "P" jumper installed.
