to the actuator. For applications requiring this type of impact,
contact Exlar application engineering to insure that the actuator is
properly sized or provisions are made to absorb the induced
energy.
3.5 Manual Drive Operating Instructions
Important: If manually driving through a brake or high
force is necessary, please consult Exlar engineering. If a
power tool is used to operate the manual drive the speed should be
limited to 600 RPM. An impact driver should never be used to
operate the manual drive.
Extreme caution should be taken when approaching end of stroke
of the actuator or system.
1) Press down on the hex until you feel you have bottomed out the
manual drive. Constant downward force is required to maintain
engagement during operation.
2) Give the hex a slight turn while observing if you are moving the
rod or not. It is possible that during engagement the gear teeth
have not completely engaged; this will prevent the gears from
meshing. If the rod is not moving continue to press down while
turning the manual drive slowly until it pushes farther down.
When this happens you have proper gear engagement.
3) After gear engagement is achieved, the manual drive can be
operated. The maximum torque input for the manual drive should
not exceed the values shown in Table 1.
4) When the manual drive movement is completed, cease the
downward force and the manual drive will disengage.
