APPLICATION
The Honeywell M7410E actuator is specifically designed to
provide modulating control together with the V5822/23,
V5832/33, and V5825B series of small linear valves.
The M7410E is used in fan-coil-units, induction units, small
reheaters and recoolers, and for zone control applications. It
is employed in electronic temperature control systems with
hot and/or cold water as the controlled medium. This actuator
is fully compatible with all controllers providing 0...10 V or
2...10 V output signals.
The 7410E actuator is designed for applications where space
is limited and minimum power consumption is required. A
microprocessor-based, high-performance positioner
guarantees accurate control.
Reliable longtime operation is ensured due to the fact that no
mechanical feedback potentiometer and no mechanical end-
switches are needed. Due to an automatic synchronization
function, the close-off point is self-adjusting.
Based on a running time of 150 s, valve positioning and flow
adjustment is very exact. Manual positioning is provided for
all actuators. The actuator is both attractive and robust in
design. A special version with auxiliary switch is available.
FEATURES
· Microprocessor-based positioner ensures precise
stem positioning
· Small size allows installation where space is limited
· Low power consumption
· Suitable for 0...10 V and 2...10 V controller output
signal (adjustable on site)
· Easy-to-operate direct/reverse acting switch
· Simple input signal override (e.g. for frost protection
function)
· Reliable longtime operation because mechanical
feedback potentiometers and mechanical end
switches are not required
· Magnetic coupling for stem force limitation and self-
adjustment of the close-of-point
· Supplied with pre-wired connection cable
· Simple, standardized valve/actuator coupling. No
tools required for mounting
· Visual valve position indicator furnished with
actuator
· Manual operation provided by the valve adjustment
cap, extra knob, or with a hexagon key
