OVERVIEW
Triac electric spring return actuators are designed to provide fail-safe positioning of valves and dampers
upon loss of supply voltage, and include on/off control and modulating control. A mechanical spring set is used to
position the controlled device to either the fully counterclockwise (OPEN) or fully clockwise (CLOSED) position
without any external power source. For ON-OFF type, a mechanical BUFFER employed at the end of the spring
stroke in order to reduce the dynamic effects of the spring return system. A clutch-less and lever-less manual
overrideis available to provide manual positioning of the controlled device.
General Information
Safety Instructions
Installation, maintenance and repair works must be performed by trained personnel.
Handling shall follow the safety and warning instruction contained in this manual.
The user should read and follow instructions contained in this operation manual. Failure to do so may result
in damages and void warranty.
Local health and safety legislation shall be complied with.
In some cases, the surface temperature may exceed 140°F (60°C). Please check surface temperature
before operation.
Installation Notices
CAUTION: For safety reasons, do not remove or inspect the SPRING STRUCTURE. Serious injury
of damage may occur unless proper tools are used.
Operating by handwheel: Do not use any tools to increase force on handwheel for operating as this
can damage the actuator or valve. Actuator MUST be returned to its spring release position before
operating electrically.
The standard spring return actuator rotates counterclockwise with power (spring compressed) and rotates
clockwise with spring released (fully closed or fully open) on loss of power.
Please read operation manual and wiring diagram before installation.
Verify that supply voltage is in accordance with the data on nameplate to prevent short circuit or
electrical/electronic parts damage.
Turn off power before wiring or maintenance.
Connect ground wire to PE point inside the actuator.
Do not parallel wire multiple actuators together without using extra relays.
Actuator should be installed in upright or horizontal position. Do not mount upside down or below horizontal.
These units are not designed to operate in vacuum spaces or where an explosive atmosphere is present.
Periodically inspect actuator enclosure to prevent dust accumulation.

Inspection, Storage, Transport
Receiving/Inspection
Carefully inspect the package for any damage resulting from shipping and report all damages to freight
carrier and seller.
After unpacking, please keep cartons and packing materials in case of product return or replacement. Verify
the items listed in packing slip or in bill of landing are the same as what were ordered, If there is any
discrepancy, please contact the seller.
Verify the technical data on nameplate and labels is in accordance with what was ordered.
Storage
The actuator should be stored in a dry area with relative humidity less than 90% (68±9°F / 20±5°C) and at
temperatures between -4°F to 104°F (-20°C to 40°C).
The product shall be stored with suitable protection from weather, extreme vibration and corrosive
substances that can damage the actuator.
Conduit plugs should not be removed until the actuator is ready to be cabled. Use suitable connections to
ensure enclosure rating is maintained when installing.
Transport
Attach ropes or hooks for the purpose of lifting by hoist only to housing and not to handwheel.
Packaged actuators shall avoid violent impact and strong vibrations and be protected from precipitation.
Lubrication
The gear train has been sufficiently lubricated at the factory and requires no additional lubrication.

INSTALLATION
Manual Handwheel
1. Insert screw through washers and handwheel before securing them to the override shaft as shown.
Turn off power to actuator when installing handwheel.
Mounting
The actuator is shipped in the designated fail position from the factory. Make sure the valve and actuator are in the
same position before mounting.
1. If the actuator is to fail close on loss of power, the valve must be in the closed position when mounting the
actuator. On the other hand, if the actuator is to fail open on loss of power, the valve must be in the open position
when mounting the actuator.
Valve open
for fail-open
actuation
Valve closed
for fail-close
actuation
Actuators are intended to be used
between a horizontal and upright
position. DO NOT mount with
actuator top below horizontal!

2. Remove valve mechanical stops and mount on the proper connection.
CAUTION: Don’t remove any parts necessary for the proper operation of the valve.
3. Check again that the valve and actuator are in the same position.
4. Install mounting hardware on the valve or mount on the valve directly, mount actuator to valve. Securely
tighten all bolts and screws once actuator screws have been started.
5. Remove actuator cover. CAUTION: Be sure power is off at the main power box.
6. Wire actuator using the wiring diagram inside cover.
7. Turn on power to actuator. CAUTION: Use extreme caution as there are live circuits that could cause
electrical shock or death.
8. Make sure if it is needed to calibrate the fully-open or fully-closed position of the actuator. Refer to to set the
fully -open or fully-closed position.
9. Replace cover and secure cover screws.
