Energy Core Ventilator
Standard Components
Vari-Green® Electronically Commutated
Motor
Features
• Soft Start – All motors
feature soft-start
technology which
eliminates inrush current
at start-up. The motors
will reliably start at any speed setting.
• Overload Protection – If the motor becomes
overloaded, it will automatically reduce its speed until
it is no longer overloaded. This means that the motor
will never operate in the “service factor” which is
possible with many AC motors.
• Locked Rotor Protection – If the motor ever
encounters a locked-rotor scenario, the motor will
automatically shut itself down. It will try to restart up
to 3 times and if after the 3rd time the motor will still
not rotate, the motor will not attempt to start again
until power is cycled.
• Thermal Protection – The motors will have an internal
thermal protection which electronically regulates the
RPM limit until an acceptable temperature is met.
Operation and Wiring
These motors have the ability to accept a plug in
potentiometer for speed adjustment AND the ability to
accept a 0-10V signal for remote control.
• Motor Potentiometer - Turn the dial with your
fingers to adjust. To increase the speed, rotate
the dial clockwise. To decrease the speed, rotate
the dial counterclockwise. Turning the dial full
counterclockwise will turn the motor off.
• 0-10 Vdc Signal - From 0-1.9V, the motor will be off
and will operate within the 2-10V range. This motor
does not require 24V power for operation.
Dampers
Gravity backdraft dampers are always included at the
discharge positions.
