3.3 Mechanical Installation

3.3.1 General

Install the 10260A series actuator in a convenient location in any orientation. Firmly bolt the 10260A to a
mounting surface that will not distort when subjected to the torque stresses generated by the actuator. The
output shaft of the actuator should be parallel to the output shaft of the driven device. The output shaft
crank arm is fully adjustable through 360°.

3.3.2 Linkage Set-up

General
Many applications require the use of a linkage assembly and often the final control element does not have a
linear torque curve. The 10260A Series Actuator linkage can be set up to achieve an optimal delivered
torque distribution for specific applications. To assist with linkage design, Honeywell offers a linkage
analysis software package (HAL). The software can be ordered as P/N 51197910-001.
Constant Torque Linkage
A constant torque linkage is employed when it is desired to provide a linear torque profile throughout the
full range of final control element travel. In this situation, the actuator and driven crank arms will be set-up
proportionally with respect to each other. Figure 3-3 shows a general linkage setup to achieve a linear
torque profile and Figure 3-4 shows the resultant profile.
