3.2 OPERATION
3.2.1 QX-Series Operation
WARNING
WHENEVER WORKING INSIDE THE ACTUATOR, CARE MUST BE
TAKEN TO AVOID DAMAGE TO THE MACHINED FLANGE SURFACES
ON THE COVER AND BASE CASTINGS. FAILURE TO DO SO CAN VOID
THE ACTUATOR’S ENVIRONMENTAL CERTIFICATION.
The QX-Series actuator is designed for On/O (Open/Close)
operation.The default position/direction of travel is clockwise,
power must be applied to terminals 1 (NEG/-) and 2 (POS/+).
To drive in the counter-clockwise direction, an additional
“control signal” must be applied to terminal 3 (POS/+); when
this“control signal”is de-energized, (and power is still present
at terminals 1 and 2) the actuator will return to the clockwise
position. Two single-pole, doublethrow limit switches control
the ends of travel; the actuator will continue to drive in the
“powered” direction until power is removed or a cam trips
an end-of-travel switch. Power may be removed mid-stroke
to position the nal drive device. Once the actuator reaches
an end-of-travel switch, power and the “control signal” may
be removed or left applied without damaging the actuator.
The actuator includes two auxiliary limit switches that maybe
used for position indication or for interlocking other devices.
3.2.2 Wiring
The QX-Series actuator operates from the customer’s
supplied external power (DC +/POS and DC -/NEG). When
power is applied to terminals 1 (NEG/-) and 2 (POS/+) the
actuator will drive in the clockwise direction. When a
“control signal” is applied to terminal 3 (POS/+), and power
is still present at terminals 1 and 2, the actuator will drive in
the counter-clockwise direction. (Refer to Figure 1 for the
power and control wiring connections.)
WARNING
USE CARE WHENEVER WORKING WITH THE ACTUATOR COVER
REMOVED. DAMAGE, SCRATCHES, OR DENTS ON THE MACHINED
FLANGE SURFACES OF THE ENCLOSURE MAY VOID COMPLIANCE
WITH NEMA, CSA, AND/OR UL SPECIFICATIONS. SEE SECTION 3.3.2
IMO 7/18
4 IMO-I3000 EN

WARNING
ACTUATORS SHOULD BE PROPERLY GROUNDED AND WIRED IN
ACCORDANCE WITH LOCAL ELECTRICAL CODE; SEE NAMEPLATE FOR
MAXIMUM CURRENT DRAW.
3.3 Adjustment of End-Of-Travel
3.3.1 Limit Switches
Two limit switches operated by cams on the output shaft
determine the exact positions where the actuator will
stop at the end of each cycle. Counting from the bottom,
the rst switch determines the CW end-of-travel position.
The second switch determines the CCW end-of-travel
position. The limit switches can be adjusted from 5° to 270°
of actuator rotation. If adjustment of the open or closed
position is required, proceed as follows:
Caution: Disconnect power supply circuit before opening
enclosure.
A. Remove the cover
Remove actuator cover. Remove the override shaft from
the actuator cover bushing; if the actuator is equipped
with a handwheel, remove the handwheel before
removing the top piece of the “two-piece”shaft from the
cover bushing. NOTE: Use caution to prevent damage
to machined ange surface of cover casting; see cover
replacement for additional information.
B. Drive the actuator to the full CCW position.
C. Adjust the CCW limit switch cam
1) Using a 1/16 inch hex wrench, loosen the set screw in
the CCW limit switch cam (the second from the bottom).
2) Rotate the cam toward the limit switch arm until the
switch just clicks closed.
3) Re-tighten the set screw on the limit switch cam
(Be careful not to over-tighten the screw).
D. Drive the actuator to the full CW position.
E. Adjust the CW limit switch cam
1) Using a 1/16 inch hex wrench, loosen the set screw in
the CW limit switch cam (the bottom one).
2) Rotate the cam toward the limit switch arm until the
switch just clicks closed.
3) Re-tighten the set screw on the limit switch cam (Be
careful not to over-tighten the screw).
F. Adjust auxiliary switches as needed, and then replace
the cover (see section 3.3.3)
NOTE: For actuators including hazardous location
certication.
Prior to installing cover, inspect machined ange surfaces
for any damage, scratches, or dents. Damage, scratches, or
dents that will not t completely in a circle having a diameter
of 1/64” will void hazardous location certications. If such
imperfections are present the damaged enclosure part(s)
must be replaced. Consult the factory for replacement parts.
3.3.2 Auxiliary Limit Switches
These switches are factory set to trip just before the endof-
travel limit switches. If adjustment is desired, the switches are
set in the same manner as the end-of-travel limit switches.
CW Indication Switch: (3rd from bottom) NO to Terminal 7
COM to Terminal 8
NC to Terminal 9
CCW Indication Switch: (4th from bottom)
NO to Terminal 10
COM to Terminal 11
3.3.3 Proper Actuator Cover Installation
1. Remove the override shaft from the actuator cover
bushing; if the actuator is equipped with a handwheel,
remove the handwheel before removing the top piece
of the “two-piece” shaft from the cover bushing.
2. Install the override shaft on the square motor shaft; if
the actuator is equipped with a handwheel, install the
bottom piece of the “two-piece” shaft on the motor
shaft and then install the top piece of the shaft onto
the bottom piece of the shaft.
3. Align cover so that the override shaft will pass through
the override bushing and carefully push it down so that
the cover ange contacts the base ange.
4. Once the cover is properly seated, tighten the screws to
secure the cover; a cross pattern is recommended for
uniform distribution of load.
5. If the position indicator is not seated to the output/cam
shaft, turn until it drops into place in order to ensure
accurate visual position indication.
3.4 Temperature Limits
3.4.1 Low Ambient Temperatures
The minimum recommended ambient temperature is -40°F.
3.4.2 High Ambient Temperatures
The maximum recommended ambient operating temperature
is 150°F. NOTE: Actuators mounted outdoors must be shaded
from direct sunlight to keep the internal temperature below
150°F. Sustained exposure to temperatures over 150°F can
damage the internal components.
3.4.3 High Media Temperatures
For media temperatures between 200°F and 300°F, a
IMO 7/18
IMO-I3000 EN 5

shielding plate (about one inch larger than the actuator
in each dimension, and at least a 1/16” thick) should be
placed between the actuator and the mounting bracket.
In addition, the actuator should not be mounted directly
above the pipe. For media temperatures above 300°F,
a valve with an extended shaft mounting arrangement
should be used.
4. MOUNTING THE ACTUATOR
WARNING
DANGEROUS VOLTAGES ARE PRESENT INSIDE THE ACTUATOR
COVER UNLESS THE POWER SUPPLY TO THE ACTUATOR HAS BEEN
SHUT OFF OR DISCONNECTED. USE EXTREME CAUTION WHENEVER
WORKING ON THE ACTUATOR WITH THE COVER REMOVED.
4.1 Actuator Installation
Verify that the output torque of the actuator is appropriate
for the torque requirements of the valve. The output torque
is listed on the actuator’s base nameplate.
Actuator Drive Output - QX-Series actuators are furnished
with a female drive output. Two bolt hole patterns (ISO
5211) are provided for actuator mounting (See gure 3).
Bracket requirements - It is mandatory that the actuator be
rmly secured to a sturdy mounting bracket. A minimum of
four bolts with lock-washers should be used to secure the
actuator to the bracket. No exibility in the bracket is allowed,
and backlash, or ”play”, in the coupling should be minimized.
The actuator output shaft must be in-line (centered) with the
valve shaft to avoid side-loading the shaft.
5. MANUAL OVERRIDE
WARNING
FAILURE TO USE MANUAL OVERRIDE PROPERLY COULD RESULT
IN DAMAGE TO THE ACTUATOR GEARING. ENSURE THAT THE
OVERRIDE IS FULLY DISENGAGED AND DO NOT USE EXCESSIVE
FORCE WHEN MANUALLY POSITIONING ACTUATOR. DO NOT DRIVE
THE ACTUATOR BEYOND THE TRAVEL LIMIT SETTINGS. FAILURE TO
FOLLOW THESE INSTRUCTIONS COULD RESULT IN DAMAGE TO THE
ACTUATOR AND/OR FINAL DRIVE ELEMENT.
To use the manual override, push the override shaft down
approximately 1/4 inch to disengage the motor from the
gear train. Failure to disengage motor prior to turning
override will cause damage to the actuator. While holding
the shaft down, turn the shaft with a wrench or handle to
the desired position. The override shaft on actuators below
1000 in•lb must be rotated in the opposite direction of the
desired direction of the output shaft. In actuators 1000 in•lb
and above, the override and the output shaft turn in the
same direction.
Do not drive the actuator beyond the limit switch settings.
The manual override shaft must be returned to its fully
upward position before the motor is re-engaged. Rotate the
shaft slightly to align the spur gears until the shaft ”springs”
back to its re-engaged position. NOTE: The rotation
direction of the output may not be the same as the rotation
of the override shaft!
6. TROUBLESHOOTING
If the actuator fails to operate:
• Check that proper voltages are present at the actuator’s
terminal connections.
• Check that all connections are properly made.
• Check that the limit switches are properly set.
• Check that the actuator has enough torque output for
the application.

actuators are rated 80% duty.
9. GENERAL OPERATING INFORMATION
For enclosure specications and dimensions, see (Table 1
and Figure 3) specications & technical information.
9.1 Enclosure Ratings and Product Certications
All QX-Series actuator enclosures are certied weathertight
and “explosionproof” (NEMA 4/4X, and NEMA 7&9) by
CSA. The enclosures are certied to meet both Canadian
and U.S. standards for applications in both Hazardous
and Non-Hazardous locations. Ensure that the actuator’s
ratings are appropriate for the application environment
prior to installation.
WARNING
WHENEVER WORKING INSIDE THE ACTUATOR, CARE MUST BE
TAKEN TO AVOID DAMAGE TO THE MACHINED FLANGE SURFACES
ON THE COVER AND BASE CASTINGS. FAILURE TO DO SO CAN VOID
THE ACTUATOR’S ENVIRONMENTAL CERTIFICATION.
9.2 Duty Cycle and Motor Protection
QX-Series actuators are equipped with a brushed DC motor
and are rated for 80% duty cycle operation in environments
at/below 104°F (40°C) and for a maximum of 30 starts per
minute. Higher temperature applications decrease the
available duty cycle.
9.3 Operating Temperature Limits
QX-Series actuators are designed to operate in ambient
environments between -40°F (-40°C) and 150°F (65°C). If the
ambient temperature may drop below 32°F, the heater and
thermostat option is recommended. In outdoor applications
where ambient temperatures exceed 80°F, actuators should
be shielded from direct sunlight. In applications with high
media temperatures, insulating blankets, heat shields and/
or extended mounting shafts should be used to maintain
ambient temperatures at the actuator within normal
operating limits.
Heaters and thermostats are recommended for all outdoor
applications and may also be used to dry condensation in
high-humidity environments.
9.4 Actuator Mounting
The actuator may be mounted in any position including
upside-down. It must be rmly secured to a direct mount
ange or sturdy mounting bracket. A minimum of four bolts
with lock washers should be used to secure the actuator to the
bracket. Flexibility in the bracket is not allowed, and backlash,
or “play”, in the coupling should be minimized. The actuator
output shaft must be in line (centered) with the valve shaft to
avoid side-loading the shaft. (See Figure 3 for output drive
dimensions and mounting hardware specications.)
9.5 Lubrication
All rotating power train components are permanently
lubricated with multi-purpose PTFE grease suitable for the
operating temperature range of the actuator. Additional
lubrication is not required in normal operation.
9.6 Problem Prevention
Most actuator problems result from improper installation.
Incorrect Wiring and Set Up - Make certain the actuator
is wired correctly and travel stops are properly set before
power is applied.
Coupling, Alignment, and Mounting - Do not add extra
torque! Make certain that the mounting arrangement is sturdy,
centered, properly aligned, and that all mounting hardware is
secure and properly tightened.
Moisture - Replace the cover tightly and make certain conduit
entry holes are sealed properly to prevent moisture inltration.
IMO 7/18
IMO-I3000 EN 7

Temperature - Excessive temperatures aect duty cycle,
actuator performance and the condition of the internal
power storage. QX-Series actuators are designed to operate
in environments below 150°F. In applications with high
media temperatures, insulating blankets, heat shields,
extended mounting shafts or o-set mounting may be
used to maintain ambient temperatures at the actuator
within normal operating limits.
9.7 Warranty
All V-Series actuators are backed by a 2-year warranty that
covers materials and workmanship. The warranty expires
24 months from installation or 30 months from delivery;
whichever comes rst.
To request a Return Authorization for an actuator within the
warranty period, please consult your local Metso distributor.
