In MEP-4x 2 x/4x 7 x models, the adjustable auxiliary
SPDT switch can be set to trip anywhere between 0°
(full CW rotation position ) and 90° (full CCW). To
adjust the auxiliary switch position, two different
methods can be followed. (Method 2 is generally
more precise.)
Method 1 (Setting Desired Dial Degrees)
1. While pressing the gear disengagement lever,
rotate the actuator to the full clockwise position
(0°) .
2. Using a small, flat-bade screwdriver, adjust the
rotary dial to the desired number of degrees (as
shown on the dial) at which the switch should
trip. For example, if the switch is set to trip at 45°
(dial halfway between 0° and 90° when actuator
is at full CW position), then Red connects
to Black from 0° to 45°, and Red connects to
Blue from 45° to 90°. As the actuator rotates,
the switch dial arrow points to the current
switch position (Red connected to Blue vs. Red
connected to Black).
3. Wire the desired auxiliary device(s) to the cable.
Method 2 (Setting where Rotation Trips)
1. While pressing the gear disengagement lever,
rotate the actuator to the point where the
auxiliary switch should trip .
2. Using a small, flat-bade screwdriver, adjust the
rotary dial to “0” . For example, if the switch is
set to trip (dial at “0”) when the actuator rotation
position is at 45°, then Red connects to Black
from 0° to 45°, and Red connects to Blue from
45° to 90°. As the actuator rotates, the switch dial
arrow points to the current switch position (Red
connected to Blue vs. Red connected to Black).
3. Wire the desired auxiliary device(s) to the cable.
NOTE: In this method, if the dial is set to “90”
instead of “0” in Step 2, switch connections
will be reversed.
NOTE: On MEP-4 9 7x models, a second switch is
fixed at 10° from full CW direction (Brown
is connected to Orange in the 0–10° range,
and Brown is connected to Yellow 11–90°).
The dial adjustment has no effect on it. (The
auxiliary switch cable is the left-hand cable,
looking from the top.)
