iVQ-E to R Range Installation and Operating Manual
This document provides necessary information for the installation and commissioning of the iVQ Range quarter-
turn electric actuator. Each unit is shipped from the factory with initial calibration of mechanical stops, cams
and switches completed for 0° –90° operation. However, these are general settings and serve as a starting point
for proper calibration of the actuator in its real-world application.
Only competent and trained personnel should install, maintain and operate iVQ actuators. Any work related to
an actuator must be carried out in accordance with this manual, accompanied manuals and related codes and
regulations. Local workplace health and safety rules should always be followed.
NOTE: Throughout the documentation we reference CLOCKWISE (CW)rotation as moving in the CLOSE direction
and COUNTER-CLOCKWISE (CCW) rotation as moving in the OPEN direction.
Receiving / Inspection
•Carefully inspect for shipping damage. Damage to the shipping carton is usually a good indication that it has
received rough handing. Report all damage immediately to the freight carrier and your seller.
•After unpacking the product and information packet, please take care to save the shipping carton and any
packing material in case of product return or replacement. Verify that the item on the packing list or bill of
lading is the same as your own documentation. If there is any discrepancy, please contact the seller.
Storage
•If the actuator cannot be installed immediately, store it in a clean dry environment. The actuator must be
protected from excess moisture and dust until you are ready to connect the electrical cables. The actuator
should not be installed outside unless it is powered up and has the proper conduit connections.
•If the actuator is to be installed but cannot be wired, please don’t remove the plastic cable entry plugs. When
the actuator is wired, it is recommended to replace with water-proof conduit fittings.
•Storage temperature should be within the standard operating temperature range of the actuator.

Before installing the actuator onto the valve or damper, check the following:
1. Check the actuator nameplate for the output torque
of the actuator. The output torque should be a
minimum of 30% greater than the actual maximum
requirement of the valve or damper. See Photo 1.
2. Check to ensure that the enclosure rating is suitable
for the area of installation.
3. Check the wiring diagram as per the wiring diagram
code on the nameplate and confirm that it meets
with the electrical requirements.
4. Check the actuator nameplate for correct voltage
prior to wiring. See Photo 1.
Actuator Installation
1. The actuators have been factory calibrated to
operate between 0° and 90°. Most quarter-turn
products will not require recalibration of these
settings. If any travel adjustment is necessary,
please refer to the “Limit Switch Setting” section
below.
2. The actuators are shipped in the full CLOSE (CW)
position. The 2 color mechanical position indicator
shows “CLOSE” (see Photo 2) and on the actuator
base the reference dimple aligns with “0” (see Photo
3). If the actuator is not in the full CLOSE (CW)
position, use the manual override to reposition the
actuator.
3. Fully CLOSE the valve or damper to which the
actuator is to be mounted. Note that the actuators
rotate CW (as viewed from above the unit) when
moving in the CLOSE direction.
4. Assemble necessary adaption components and
attach the actuator to the valve or damper.

5. Tighten mounting bolts, making sure actuator is centered on the valve/damper drive shaft.
6. Utilize the handwheel to check for unobstructed manual operation from fully CW to fully CCW positions.
(See “Manual Override” section below.)
7. Remove the cover and make the electrical connections as per the wiring diagram. Typical connections have
AC Neutral or DC (-) to terminal 1 and AC Live or DC (+) to terminal 3 or 4. Connection to terminal 3 to OPEN
(CCW). Connection to terminal 4 to CLOSE (CW).
8. For models where auxiliary switches are provided, terminals A - F are for 2 x SPDT adjustable auxiliary
switches. They are dry type Form C rated 5A @ 250V AC max. Terminals A, B & C are for the OPEN position
auxiliary switch (adjustable). Terminals D, E & F are for the CLOSE position auxiliary switch (adjustable).
9. Connect the ground wire to PE inside the electric actuator.
10. Replace cover and secure cover screws.
11. Do NOT apply power at this time. See “Commissioning” section below.
12. Check below explanation of Duty Cycle. The intended service should not go above the maximum duty cycle
as noted on the actuator nameplate.
Installation Notes
•These actuators are designed to be used between a horizontal and upright position. Do NOT mount the
assembly with the actuator top below a horizontal position.
•When installing conduit, use proper techniques for entry into the actuator. It is preferred that the conduit
entries face downward. Use drip loops to prevent conduit condensate from entering the actuator. Use proper
fittings to maintain the NEMA 4X integrity of the housing. Seal (pot) the conduit entries.
•Use proper wire size to prevent actuator failure. All terminals accept 12 -18AWG solid/stranded wire.
•Mechanical travel stops are factory calibrated for 90° operation. These stops are NOT designed to adjust
mechanical rotation by more than +/- 3°. They are for positioning the handwheel only.
•Do NOT touch any components on the PCB with metal tools or bare hands.
•The internal heater is to be used in all applications. Do NOT install the actuator outdoors or in humid
environments unless it is powered up and the heater is functioning.
•Do NOT parallel wire multiple actuators together without utilizing isolation relays. If this is your intention,
please contact Innovative Actuation Incorporated for a multiple actuator parallel wiring diagram.

Duty Cycle
Duty cycle is the percent of time that an actuator spends running as a fraction of the total time. Duty cycle is
directly related to heat; excessively repositioning an actuator typically results in motor overheating, which can
cause permanent damage and/or reduced service life. Duty performance can be calculated as follows:
(example iVQ-F Range actuator running 17 seconds ON and 40 seconds OFF)
Runtime = 17s, Total time = 17s + 40s = 57s, therefore this duty cycle would be 30% (17/57). Standard duty with
iVQ Range actuators is 30% so it is within the allowed limit. 40 seconds is the minimum off time in this example.
Manual Override
A handwheel is supplied to be used as a manual
override. See Photo 4. If the handwheel is supplied with
a rotating grip, ensure that the nut on the bolt is
threaded about 1” onto the bolt. See photo 5. When the
bolt is threaded into the handwheel the nut will prevent
the bolt from being threaded further into the
handwheel allowing the grip to rotate freely.
The handwheel does not require a clutch mechanism.
Clockwise rotation closes the valve or damper.
Counter clockwise rotation opens the valve or damper.
The handwheel does not rotate when the actuator
motor is running.
If the handwheel is rotated when the actuator is under
electrical power the actuator will return to its last
position after the handwheel is released.
Do NOT utilize any mechanical advantage devices to
rotate the handwheel (pipes, wrenches, extension bars,
etc.).

Mechanical Stops
The mechanical stop screw limits handwheel operation. Adjusting these bolts will increase or decrease the valve
travel. They are not to be used as an electrical travel limiting device. The mechanical stop screws are always set
before the limit switch settings.

•The actuator will drive to the full CLOSE (CW) position (as viewed from ABOVE the
actuator).
•If this is NOT the correct stop position, refer to the “Limit Switch Setting” section in this
manual to reset LS2.
Limit Switch Setting
The travel cams are set to control the open and closed position of the valve. The position is set to stop the travel
of the actuator when the travel cams activate the limit switch. Standard is two limit switches (LS1 & LS2), one
for open, one for closed. LS1 & LS2 limit the maximum range by disabling the electric motor. LS3 & LS4 are
optional. See photo 8. They allow external equipment to confirm that the valve has reached the fully open and
fully closed positions. Care must be taken to ensure that LS3 & LS4 are set to trip prior to LS1 & LS2 so that
proper end of travel indication is provided. The travel cams can be adjusted with 2.5mm Allen key.
•To set LS1, the OPEN position (Full CCW Position):
oTurn power off and use manual override
to turn valve to the open position.
oRemove cover and loosen the set screw on
the bottom cam, TC1.
oRotate cam clockwise to reset the switch
