1. MP-210 motor packs are
designed for use on model
WD-200 series dampers
only.
2. For single panel damper,
insert tab of Motor Bracket
into the slot on the side of
the frame. For dampers
with center bars, the tab of
the Motor Bracket should
be inserted into the slot on
the bottom of the center bearing rail.
Position bracket over the two holes on the bottom of the
frame and secure with the #10 hardware provided .
3. Connect the Motor Arm Assembly to the Connecting Link
using the provided hardware.
NOTE: The Connecting Link or Links have been installed
on the damper at the factory.
4. To adjust the Actuator Linkage Assembly, pull back on the
Actuator Arm Assembly until a slight amount of tension has
been applied to the Actuator Spring. Tighten the fasteners
between the Connecting Link and the Actuator Arm
Assembly. Fasteners should be placed as far apart as
possible. This provides greater stability to the linkage. To
increase spring tension raise the spring up on the bracket.
To decrease spring tension lower the spring.
NOTE: It is important to avoid too much spring tension;
use just enough tension to help close the damper.
Too much tension could impair opening of the
damper.
5. Actuators are supplied with junction boxes and covers.
When wiring, make sure the supply voltage agrees with the
actuator voltage. On dual voltage motor packs, be sure to
connect the proper motor leads for the correct voltage and
insulate any unused wire. The voltage of each specific
model is stamped into the actuator housing or on a label
that is affixed to the actuator (see page 2 for typical wiring
diagrams).
6. If the damper fails to open properly, check for one of the
following causes.

A. Motor pack fails to open the damper completely
• Check for an 'out of square' or racked
damper
• Spring tension too great
• Excessive voltage drop
B. Motor pack fails to function
• Check for correct voltage
• Check for proper wiring
Motor pack Quantity
One or two motor packs may be required depending on
damper size. Single panel dampers have one column of
blades and one actuator is installed as shown in the Single
Panel view above. Double panel dampers have two columns
of blades and one actuator is installed as shown in the the
Multiple Panel view above. Triple panel dampers have three
columns of blades and two actuators are installed as shown
in the Multiple Panel view above.
Actuator Specifications
MP 210 motor packs are single phase 60 Hz (50 Hz optional)
shaded pole stall type impedance protected electric actuators
and are supplied in various voltages (see chart below). For
277, 575, or 600 volt operation a transformer and a 115 volt
motorpack is required.
