TorqPlus EM-Series Actuator
Installation and Operating Instructions
2
Once manual rotation is complete, remove the wrench and release the knob.
Note: The knob will remain
up until the actuator is electrically operated and the engagement slots on the output shaft align themselves
with the engagement slots on the output gear. Maximum time for re-engagement should be no greater than
45 seconds. Never pound on the center shaft.
800 Series
CAUTION: Do not apply more than the maximum rim pull rating of the handwheel. Rim pull should be no
greater than 5 pounds for a 2,000 in•lb actuator, 12.5 pounds for a 5,000 in•lb actuator, and 25 pounds for a
10,000 in•lb actuator.
Turn handwheel in the direction desired, as marked on the handwheel.
Avoid rotating beyond the driven
device’s operating quadrant.

Actuator Attachment
Manually operate the driven device several times to insure smooth trouble free operation and place in the
full CCW position as viewed from above.
It is highly recommended that each driven device be torque tested in its worst case condition to verify
proper sizing of the actuator.
If the driven device is equipped with mechanical stops, verify the travel limit cams toggle short of the
mechanical stop’s contact points.
Unless specially ordered, the actuator is shipped in the fully CCW position.
Carefully follow all instructions supplied with the device and/or the interconnecting hardware. When mounting
is complete, all connections should be tight, but not binding. It is also recommended to declutch and
manually operate the actuator during the mounting process to ease installation and
eliminate binding.

Cover Removal
Shut of all power to the actuator.
Loosen the socket set screw in the position indicator and remove the declutching/indicator knob from the
top of the unit. Note: This step is not required on the 100 and 800 series.
Remove all the cover attachment screws located around the flange and carefully lift the cover up and off.
Note: If manual operation is required with the cover removed, it is imperative that the declutching/
indicator knob replaced on the output shaft after the cover has been removed.
