CONNECTIONS
AUXILIARY SWITCH
The M9484E has 1 internal auxiliary switch. The switch
wires are color-coded as follows: solid yellow-normally
closed (N.C.); solid red-common (COM.); solid
blue-normally open (N.O.).

STROKE SEl-lING
On M94XXD,E,F motors, stroke is field adjustable and
can be set from 90" to 160". Motors are shipped in 90"
position. In order to set stroke, both mechanical and elec-
trical adjustments are required. The mechanical adjust-
ments (cams) establish the full open (clockwise, n as
viewed from the power end) and full closed (counterclock-
wise 0 positions of the motor shaft. The electrical
adjustment (trim pot) provides sufficient total stroke angle
to ensure that cams will actuate both limit switches.

The M9484F has 2 internal auxiliary switches which
may be used to prove low fire and high fire positions.

connected to outer (left) switch. This switch makes red to
yellow and breaks red to blue as motor closes.
2. Wires connected to the inner (right) switch are black
with colored tracers. To prove high fire, use red tracer
(common) and blue tracer wires. The right switch makes
red tracer to blue tracer and breaks red tracer to yellow
tracer as motor opens.
Color coding and switching action are tabulated below
to aid the installer.

BEFORE SETTING STROKE:
1. Remove top cover from motor.
2. Disconnect controller from motor.
3. Connect R,B,W terminals on 135 ohm potentiome-
ter (Q209 or S963) to matching terminals on motor.
SETTING 160" STROKE (Fig. 8):
1. Turn stroke pot fully clockwise f7
2. Drive motor to mid-position using 135 ohm pot
(Q209 or S963), or by jumpering B-R-W.
3. Insert l/8 in. screwdriver blade into slot on inner
yellow cam and MOVE TOP OF SCREWDRIVER as far as
possible counterclockwise n (viewed from power
end). Repeat in successive cam slots until inner cam is
against counterclockwise 0 stop.
