OVERVIEW
Sharpe®electric quarter-turn actuators offer a wide range of torque output models. The product
design is based on a self-locking worm drive principal, which provides for a smooth running,
dependable, robust drive system. All models are ISO 5211 compliant and most have a visual
position indicator on top of actuator cover and manual override
LUBRICATION
The gearbox of the Sharpe actuator is enclosed, and it has already been lubricated sufficiently
with high temperature lubricant at the factory sufficient for use for up to two years.
IMPORTANT NOTICES & MAINTENANCE
Notices:
Make sure the voltage is correct before wiring.
Turn off power before for maintenance purposes.
Seal the casing and conduit entrance after wiring to prevent dust or water contamination.
The angle of installation must between 0~180°. Do not install upside down or below the
horizontal.
Do not install when hazardous or explosive gases may be present.
The frequency of open and close is restricted based on duty cycle. Avoid too high
frequency.
When more than one electric actuator needs to operate simultaneously, please connect
individually.
Always connect the ground wire to the inside of the electric actuator.
Not intended for vacuum spaces and avoid installing near explosive atmospheres.
To avoid functional failure caused by statics, do not touch any components on the PCB
with metal tools or bare hands.
Storage:
The actuator should be placed in a clean and dry place, and protected from the weather
and extreme vibration.
If actuator needs be stored outside, it must be protected from excess moisture, dust,
and weather.

INSTALLATION
1. Before mounting actuator, verify that the torque requirement is less than the output
torque of the actuator. (The suggested safety factor is 30% of the max. torque of
valve.)
1. For example :
If the maximum valve torque is 80Nm - 80 × 1.3(safety factor) =104 Nm
104Nm ＜150Nm SEA 13 is OK!
104Nm ＞90Nm SEA 8 is not OK!
2. Check if the output shaft fits to the stem of valve before inserting into actuator. Please
use mounting plate or adapter to connect if it does not match.
3. Insert output shaft adapter into actuator. Make sure it fits satisfactory.
4. Determine that actuator position, open or closed, matches with position of equipment
prior to mounting. Use manual override to change position if necessary.
5. Remove valve’s manual device and mount on the proper connection.
6. Check again that the valve and actuator are in the same position.
7. Install the actuator to valve directly or with mounting kits, then tighten all screws and
nuts.
8. Remove actuator cover.
9. Wire actuator using the wiring diagram inside cover.
10.Supply power to actuator.
11.Make sure if it is needed to calibrate the fully-open or fully-closed position of the
actuator.
12.If the actuator is modulating type make sure set the required settings.
13.Replace cover and secure cover screws.

TRAVEL CAM & LIMIT SWITCHES ADJUSTMENT
The travel cams are set to control the open and closed position of the
valve. LS1 & LS2 limit the maximum range by disabling the electric
motor.
LS3 & LS4 are optional. They allow external equipment to confirm
that the valve has reached the fully open and fully closed positions.
IMPORTANT: If LS3 & LS4 are fitted, they should be set to trip
prior to LS1 & LS2 to avoid over-travel.
A 2.5mm hex keywill be required to adjust cam settings.

MECHANICAL STOPS (cont.)
For Manual Operation:
o Set the open stop.
Remove power from actuator.
Loosen locknut on the open stop stud (left side) and unscrew it a few
turns.
Unscrew the stop stud.
Manually turn the actuator to the desire limit position.
Screw in the stop stud until it contacts the internal cam, then reverse one
rotation.
Tighten the locknut.
Check that the electrical limit switches can still be reached.
o Set the close stop.
Remove power from actuator.
Loosen locknut on the close stop stud (right side) and unscrew it a few
turns.
Unscrew the stop stud.
Manually turn the actuator to the desire limit position.
Screw in the stop stud until it contacts the internal cam, then reverse one
rotation.
Tighten the locknut.
Check that the electrical limit switches can still be reached.
Failures to ensure the electrical limit switches are reached before the mechanical stops are
hit, when operating in electric mode, can cause personal injury or damage to the actuator.
