than one disconnect provided on models
with auxiliary switches. Failure to follow
electrical safety precautions with live electrical
components could result in injury or death.
WARNING
If both conduit connections are used in line-
voltage models, they MUST be externally
connected during installation. The nonmetallic
enclosure does not provide grounding
connection between the two conduit
connections.

MEP-4xxx Direct-Coupled Actuators (40 to 90 in-lb.) 4 Applications Guide, AN0513A Rev. J
Actuator Torque Selection
Damper manufacturers should provide information
about the required minimum actuator torque. If
that information is not available, use the following
general guidelines to calculate the required torque.
(Square feet for a rectangular duct can be calculated
by multiplying the height and width in inches and
then dividing by 144.)
After minimum torque is known, see the actuator
data sheets to select the appropriate model.
Heat/Cool/VAV Applications (with the CTE-5202 Thermostat)
MEP-4xxx actuators can be used in single zone pro-
portional heating (baseboard heaters) and cooling
(chilled beams) with valves or SCR control as well as
pressure-dependent VAV applications. For details of
a variety of sample applications, see the CTE-5202
Applications Guide.
(For an example of a fail-safe application on an
outside air damper, see Fail-Safe Direction (MEP-
42/45/49xx) on page 13.)

The HCO-1151 enclosure kit (consisting of a metal
mounting plate, plastic cover, non-rotation bracket,
plug caps, and screws) is designed to protect actua-
tors from inclement conditions. See also the HMO-
4521 liquid-tight cord grip.
An HMO-4521 liquid-tight cord grip threads into
conduit ings on MEP-4xxx actuators (except the
MEP-4003) when an ingress protection rating of
IP54 is required. The HMO-4521 accepts 0.18 to 0.40"
diameter cables. There are ve per pack. See also the
HCO-1151, HPO-4001, and HPO-4051.

Troubleshooting
Auxiliary Switch Does Not Work
• Check the auxiliary switch seing. See Auxiliary
Switch (MEP-4x2x/4x7x) on page 12.
• Check the wiring. (See Wiring Issues on page
10.)
Fail-Safe Does Not Work
• After initial connection or reconnection to power
on MEP-42x2/45x2/49x2 proportional models,
proper fail-safe operation might be delayed
up to 30 seconds (until the capacitors are fully
charged).
• Check the Fail-Safe Direction switch. See Fail-
Safe Direction (MEP-42/45/49xx) on page 13.
Feedback Does Not Work
• Check the feedback switch seing. See Propor-
tional (MEP-4xx2) Models Setup on page 10.
• Check the wiring. (See Wiring Issues on page
10.)
No Rotation
• After initial power-up, proportional fail-safe
MEP-42x2/45x2/49x2 actuators delay enabling
motor operation until the fail-safe capacitors are
charged. No actuator rotation will take place for
at least the rst 30 seconds.
• Check that direction switches are fully engaged
in the proper position. See Proportional
(MEP-4xx2) Models Setup on page 10 and
Tri-State/2-Position Rotation Direction on page
11.
• Check that the shaft moves freely. (Press and
hold the gear disengagement lever and manually
rotate the shaft.)
• Check for a tripped circuit breaker to the trans-
former (or power supply).
• Check polarity and strength of input signal.
• Check for proper supply voltage from the trans-
former (or power supply) and that it has enough
capacity (VA) for all connected devices. See their
respective data sheets and Tips for Connecting
24-Volt Power Application Note (AN0604D).
• Check the wiring. (See Wiring Issues on page
10.)
Rotation in Wrong Direction
• For proportional models, check the position of
the direction switch (Switch 2). See Proportional
(MEP-4xx2) Models Setup on page 10.
• For tri-state and tri-state/two-position mod-
els, check the CW/CCW wiring and rotation
direction switch if applicable. See Tri-State/2-
Position Rotation Direction on page 11.
• For fail-safe operation, check the Fail-Safe
Direction switch. See Fail-Safe Direction (MEP-
42/45/49xx) on page 13.
Stroke Range Is Wrong
• For proportional models, check the auto-
mapping. See Proportional (MEP-4xx2) Models
Setup on page 10.
• Check the adjustable stop.
• Check the voltage from the controller or thermo-
stat.

WARNING
Risk of electrical shock in line-voltage models.
Disconnect ALL power before servicing. More
than one disconnect provided on models
with auxiliary switches. Failure to follow
electrical safety precautions with live electrical
components could result in injury or death.
WARNING
If both conduit connections are used in line-
voltage models, they MUST be externally
connected during installation. The nonmetallic
enclosure does not provide grounding
connection between the two conduit
connections.
Wiring Issues
• Check for correct wiring for the application.
• Check the wiring at the connected devices.
• Use a voltmeter and ohmmeter to check the
terminals for expected values.
• See Tips for Connecting 24-Volt Power Applica-
tion Note (AN0604D).
NOTE: Wiring must be adequate to avoid exces-
sive voltage drop on long runs! Allow
plenty of “cushion” in measurements. A
meter may be too slow to register tran-
sient dips or peaks during startup.
Configuration
Proportional (MEP-4xx2) Models Setup
NOTE: Before Jan. 2014, MEP-40x2/48x2
proportional models had 0–10 VDC inputs
and 0–5 or 0–10 VDC feedback (only).
From 2014 through July 2015, they had
2–10 VDC inputs and 1–5 or 2–10 VDC
(only) feedback instead. Starting in August
2015, all these options were available and
selectable via a jumper and slide switch.
NOTE: Before August 2015, the MEP-
42xx/45xx/49xx fail-safe proportional
models had 2–10 VDC inputs and 1–5 or
2–10 VDC feedback (only). Starting in
August 2015, 0–10 VDC inputs and 0–5 or
0–10 VDC feedback were also available and
switch-selectable.
NOTE: When the 0–10 VDC input is selected,
selectable feedback options are 0–5 or 0–10
VDC. When the 2–10 VDC input is selected,
feedback options are 1–5 or 2–10 VDC.

Tri-State/2-Position Rotation Direction
Tri-state/two-position MEP-4xx1/4xx3 models (ex-
cept MEP-4003) have switches for selecting rotation
direction. Be sure switches are set correctly for the
application.
• Non-fail-safe MEP-4xx1/4x13 models (beginning
in Jan. 2014) have a slide switch to the right
of the terminal block. See the MEP-4000/4800
Series Installation Guide for more information.
Two-Position Wiring (MEP-4001/3/4/5)
MEP-4xx4/4xx5 two-position actuators have “tradi-
tional” two wires for 24 VAC/VDC or 100–250 VAC
signal/power.
• Fail-safe MEP-4x51 and fast-acting MEP-4x01
models have selector switches to the left of the
terminal block. See the MEP-4200/4500/4900 Se-

(45–90°)
In MEP-4x2x/4x7x 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 dierent
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, at-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, at-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-497x models, a second switch is
xed 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 eect on it. (The
auxiliary switch cable is the left-hand cable,
looking from the top.)
