Vari-Green Motor Quick Start Guide
When delivered, the Vari-Green Motor is pre-
programed to run from either an on-board dial or a
0-10 VDC control signal. A 0-1.99 Volt control signal
will be received as a “stand-by” command.
A run command is acknowledged, as well as a
speed reference from 2-10 V.

NOTE:
Factory default settings:
1. Terminal 2 is set as an ENABLE command. From the
factory there is a jumper from terminal 1 to 2. A START/
STOP switch can be used between these terminals to
ENABLE/DISABLE the drive.
2. When this Vari-Green Motor is ordered in a 0-10 VDC
Control configuration, the motor is shipped with a jumper
between terminal 5 and 6. This will run the motor at full
speed when power is connected. Remove this jumper
before landing 0-10 VDC control wires.
Step 3
Install motorized backdraft damper wiring, if
applicable. The relay RL-1 is set from the factory to
close when a run command is given.

Step 4
Apply power to unit. If a control signal
is present, the RL-1 relay will close and
the motor will ramp up to the
referenced speed. If a jumper is
installed between terminals 5 and 6,
the motor will go to 100%.
Step 5
Balance the fan. Whether changing the position of
the on-board dial or adjusting the control voltage,
the fans speed can be set from the minimum to the
motor’s factory programmed maximum speed.
Re-apply the motor cover.
