1.0 General
HQ series electric actuators are design to provide reliable and efficient operation of 90 degree quarter turn
valves, dampers, etc.
Warning: Use caution when working in, with, or around valves and
actuators. High pressures, forces, voltages and flammable media can be
present
Warning: Failure to follow instructions for proper electrical wiring, storage,
set-up and maintenance may cause serious injury, damage equipment, or
void warranty.
Pre-Installation Inspection
Verify the actuator nameplate to insure correct model number, torque, operating speed, voltage
and enclosure type before installation or use.
It is important to verify that the output torque of the actuator is appropriate for the torque
requirements of the valve and that the actuator duty cycle is appropriate of the intended application
2.0 Actuator Mounting
Do not lift the actuator by the handwheel
The actuator may be mounted in any position
The HQ- Series actuators are supplied with a female drive output. ISO5211. Bolt patterns are provided for
actuator mounting. The actuator drive bush is removable for ease of machining.
It is mandatory that the actuator be firmly secured to a sturdy mounting bracket or directly mounted to the
valve’s ISO mounting pad. High tensile bolts or studs with spring locking washers must be used.
The valve output shaft must be in line with the actuator output drive to avoid side-loading the shaft.
To prevent backlash, no flexibility in the mounting bracket or mounting should be allowed.

5.0 Power Requirements
Consult the nameplate of the actuator for duty cycle and current draw information
6.0 Duty Cycle
Duty cycle rated IEC34 – S2 (30%)
Exceeding the actuator’s rated duty cycle may cause thermal overload.
7.0 Handwheel Declutch
HQ actuators are provided with a declutchable manual override system.
To manually operate the actuator, pull the manual declutch lever towards the handwheel until it remains in
position.
Turn the handwheel until the valve reaches the required position
Turn clockwise to close and counter -clockwise to open
☞The manual declutch lever has motor preference, meaning that when the motor is energized, the lever
will automatically shift to auto position.
7.0 Mechanical Travel Stop Adjustment
Built-in mechanical stops are provided to prevent handwheel operation beyond total valve travel
Loosen both locknuts and back out the stopbolts
Run actuator electrically to fully closed position
Screw close stopbolt in until it it seats, then back
Off ½ turn, Install washer and tighten locknut
Run actuator electrically to fully open position
Screw open stopbolt in until it it seats, then back
Off ½ turn, Install washer and tighten locknut
☞Do not set the Actuator position limit switches to drive into the mechanical stops. Damage can occur
of electric unit is allowed to repeatedly stall into the end stops.

HQ Series I&M Manual HQ-400-1005 7
9.0 Electrical Connection
Move valve to mid-position by handwheel. This will allow sufficient time to stop actuator in case of
improper hook-up or reversed power phases
Identify means of removing power during hookup
Be sure no erroneous remote control signals can be received causing actuator to energize
Electrically operate the valve in the open direction. If the valve closes, actuator must be stopped and
the power leads reversed to correct voltage phasing or improper field wiring.
Set all field conduit entries in accordance with National Electric Code Requirements
☞Improper power voltage phasing eliminates protection of both the position limit switch and torque
switches, risking valve damage.
10.0 Limit Switch Setting Instructions

HQ Series I&M Manual HQ-400-1005 8
10.0 Limit Switch Setting Instructions (cont)
Operate the actuator manually to closed position
Using a hex wrench, loosen the cam adjustment screw in the CLOSE limit switch cam
Rotate the CLS cam towards CW limit switch lever until the switch ‘clicks’
Tighten set screw with hex wrench
Operated the actuator manually to open position
Using a hex wrench, loosen the cam adjustment screw in the OPEN limit switch cam
Rotate the OLS can towards CCW limit switch lever until the switch ‘clicks’
Tighten set screw with hex wrench
11.0 Torque Switch Adjustment
The torque switches are adjusted at factory to protect actuator and valve against over torque.
Should adjustment be necessary, please contact the factory, or your local EIM distributor for assistance.
12.0 Reverse Acting (Counter Clockwise to Close)
Standard factory actuators are normally set to clockwise rotation to close. However the rotation can be
reverse to counter-clockwise to close by simply reconfiguring the wiring as follows:
Exchange 9 and 10 in main actuator terminal block
Exchange 11 and 12 in main actuator terminal block
If a PCU card is installed:
Exchange Potentiometer input wires P1(Orange wire) and P3 (Grey wire) on PCU
Change the direction of the indicator (HQ-200 and 300 only)
Re Calibrate by using Auto Calibrate feature
14.0 Lubrication
The HQ series actuators are totally enclosed units with a permanently lubricated gear trains (Moly EP
Grease). Once installed lubrication should not be required. However, periodic preventative maintenance
will extend the operating life of the actuator.

HQ Series I&M Manual HQ-400-1005 9
15.0 MDPI Settings
Manually rotate actuator to fully closed position
Remove actuator cover
Loosen indicator screw
Adjust indicator to correct orientation
Tighten indicator screw
Replace cover
Check indicator alignment
16.0 Maintenance
At least once a year a check should be make of your EIM HQ Series Actuator
Disconnect all power to actuator.
Open Electrical Enclosure. Inspect and tighten all electrical connections
Visually inspect for any electrical or mechanical damage. Replace worn or damaged components.
Check lubrication consistency and levels. Fill or replace if required.
17.0 Storage
Actuators must be stored in a clean, cool and dry area. The unit shall be stored with the cover installed
and the conduit openings sealed. Storage must be off the floor, covered with a sealed dust protector.
