Introduction; Product Description; Applications - Honeywell HercuLine 10260S Installation, Operation And Maintenance Manual

Product Description

Honeywell's 10260S industrially rated rotary smart actuators are precision engineered for exceptional
reliability, accurate positioning, and low maintenance. (Figure 1) Designed for very precise positioning of
dampers and quarter turn valves in the power and processing industries, the 10260S performs especially
well in extremely demanding environments requiring continuous-duty, high reliability, and low
maintenance.
Precise positioning of the actuator is achieved through state-of-the-art motor control and positioning
electronics. The motor starts and stops almost instantaneously, preventing overshoot and hunting.
Positioning repeatabililty of 0.2% span or better is achievable for extremely tight process control to take
full advantage of modern controllers.
A no-burnout synchronous induction motor is combined with a heavy-duty precision-machined output
worm gear mesh providing a responsive, low maintenance, and non-backdriving actuator. Accidental stalls
up to 100 hours can be withstood without damage to the gear train. End-of-travel limit switches are
provided as standard equipment to prevent damage to the valve or damper and are backed up by mechanical
stops.
Honeywell electric actuators provide instantaneous response to a demand signal, eliminating system non-
linearity due to dead time. Additionally, since the actuator is electric, the costs associated with providing
and maintaining a clean, dry air supply are eliminated.
A heavy duty cast crank arm and precision rod-end bearing is provided with each 10260S actuator. Crank
arms can be positioned at any angle on the output shaft and an adjustable radius is provided to allow
flexibility in linkage set-up.
All 10260S actuators are equipped with a manual handwheel for operation during loss of power or
installation. A local auto/manual handswitch can be provided for local operation and has an "out of auto"
contact to annunciate that condition.

Applications

Honeywell actuators have a long and respected history in the industrial actuator market. 10260S actuators
are designed for precision modulation of final control devices such as dampers, vanes, fluid couplings,
scoop tubes, fuel/air ratio valves, windbox dampers, and coal mill dampers, and quarter turn valves. The
robustness of the design serves as the basis for long-term reliability and reduced operating costs.
