Auxiliary Switch (4x2x)
In MEP-4x2x 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 slightly more
precise.)
Method 1
1. While pressing the gear disengagement lever
(see Illustration 1), 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 S1 is connected to
S2 from 0° to 45°, and S1 is connected to S3 from
45° to 90°. As the actuator rotates, the switch dial
arrow will point to the current switch position (S1
connected to S2 vs. S1 connected to S3).
3. Connect the auxiliary unit to the terminal block
(see Illustration 7).
Method 2
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 S1 is connected to S3 from
0° to 45°, and S1 is connected to S2 from 45° to
90°. As the actuator rotates, the switch dial arrow
will point to the current switch position (S1
connected to S2 vs. S1 connected to S3).
3. Connect the auxiliary unit to the terminal block
(see Illustration 7).
NOTE: The SPDT switch is rated for 6 A with
resistive load or 3 A with motor load @ 250
VAC.
