APOLLO AE-SERIES ELECTRIC ACTUATORS
General Installation, Operation, Specifications, Maintenance and Trouble Shooting Instructions
The following is intended as a guide only in installing and operating the electric actuator. The
manufacturer assumes no liability whatsoever for any personal injury or other special or consequential
damages that may occur. There are no warranties as to suitability for a specific application or purpose.
Installation / Mechanical Operation
• Verify that the valve breakaway torque is less than the rated output torque of the actuator.
• Any mechanical stops that would interfere with the operation of the actuator must be removed
before installation of the actuator, i.e. lever, travel stops, etc.
• The actuator output coupling must be centered with the valve stem to prevent side loading, which
causes premature stem packing wear.
• The AE-Series actuator is not recommended for actuation of butterfly valves or other similar
resilient seated valves, unless installed with Motor Break option.
• To use the manual override feature (identified on cover label), the override shaft must be pressed
down firmly at least 1/4” in order to disengage the motor from the gears. The manual override is
not designed to overcome torque in excess of the rated torque of the actuator. Serious damage
to the gear system may result from excessive turning force on the manual override.
• The AE-Series actuator may be mounted in any position, i.e. horizontal, upside down. If the
conduit entrance points upward, conduit piping must be oriented as to prevent condensation from
entering the actuator from the conduit pipe.
Electrical Operation
• Always verify that the supply voltage and required voltage are the same.
• AE-series 24VAC, 115VAC and 230VAC actuators use capacitor run-reverse induction motors,
which create higher feedback voltages that the supply voltage. Control devices connected to
terminals 3 and 4 must be rated for 250VAC minimum for 15VAC actuators, (440VAC min. for
230VAC actuators: 125VAC min. for 24VAC).
• Do not wire actuators in series or parallel with another actuator or other electrical equipment due
to the induction feedback voltage created by the motor.
• Separate (isolated contacts) are required for each actuator.
• When wiring DC voltage actuators, verify that terminal polarity is correct (pos.+ & Neg.-). Failure
to do so will cause the actuator to operate out of its normal 90 degree rotation.
• The AE-Series actuators are designed to operate at 25% duty cycle at temperatures below
100°F. This means that for a cycle time of 25 seconds the actuator must rest for 75 seconds.
This is an average. For example: The actuator may cycle several times in a row, but must rest
for a period 75% longer that the time it operated.
• All models require electrical power to both OPEN and to CLOSE the actuator and valve.
Maintenance
Under normal circumstances the actuator will not require additional lubrication. All of the actuator’s
essential components are permanently lubricated at the factory.
• Seal conduit entrances to prevent water or dirt from entering the housing. Excessive moisture
can cause premature wear or corrosion within the housing.
• Periodically inspect actuator and valve assembly for worn parts, loose fasteners, or damage to
the outside of the unit.
