5. The integrated actuators can be mounted and operated in any orientation. Properly plug or
vent the holes in the protection tube (4) to prevent dirt and moisture from contaminating the
actuator (translating tube models only).
6. Never allow the integrated actuator to retract beyond the minimum closed position or extend
beyond the maximum open position, as damage to the unit can occur. Refer to Section 3-5 for
travel limit information.
7. External temperature may exceed 200 degrees F. near maximum duty cycle. Use caution to
prevent personal injury.
8. Do not use in applications where integrated actuator can be pressed against an immovable
object.
9. A brake motor is required on all integrated actuators that have a double lead. Only integrated
actuators featuring single lead acme screws are self-locking. A brake motor is recommended
on actuators with double-lead screws (DIA).
1-6 General Installation instructions
1. Ensure that all personnel who will service or operate equipment are familiar with its use and
limitations.
2. Secure or remove the load before any installation procedures begin.
3. Be certain the rating of the actuator meets or exceeds the load.
4. Integrated actuators must be mounted on a rigid structure sufficient to support the maximum
possible load. An under-designed structure could lead to premature wear or failure.
5. Drive shaft alignment is critical. Misalignment will cause reversing stresses in rotating
members and will lead to fatigue failure. Correct coupling specification is critical for systems
with more than one integrated actuator.
6. For systems with more than one integrated actuator, confirm that the integrated actuators and
shafts operate without binding or excessive force before power is applied.
7. When fastening the load to an integrated actuator, make sure the actuator is in the retracted
position. This positions the load accurately with respect to the lifting screw centerline. Never
pull the translating tube to one side to make connection with your structure. Fully extend the
integrated actuator to make sure the load is aligned with the translating tube.
8. All integrated actuators are to be mounted with S.A.E. Grade 8 bolts or equivalent.
9. Torque the mounting bolts in a systematic pattern to avoid damage to the actuator.
10. Optional limit switches, which may be furnished with the integrated actuator, are NOT pre-set.
They require field adjustment before use.
Section II
Maintenance
2-1 Lubrication
1. Integrated actuators are lubricated before leaving the factory.
2. Do not operate integrated actuators without lubrication.
3. For normal operation, traveling nut Integrated actuator screws should be greased at least once
per month.
4. The lifting screw and translating tube are lubricated with Mobilgrease XHP 461 grease, or
equivalent.
5. The products listed are recommended by the lubricant manufacturers to meet the
requirements for normal operation. The listing of brand names is solely for the convenience of
users of Joyce equipment and their lubricant suppliers; it does not constitute any endorsement.
