M6410C/L, M7410C
Small 3-Position Linear Valve Actuators
PRODUCT DATA
GENERAL
The Honeywell M6410C/L and M7410C actuators are
specifically designed to provide floating control together with
the V5822/23 and V5832/33 series of small linear valves.
The M6410C/L and M7410C actuators are used in fan-coil-
units, induction units, small reheaters and recoolers and for
zone control applications. They are employed in electronic
temperature control systems using hot and/or cold water as
the controlled medium.
The M6410C/L and M7410C actuators are suitable for
Honeywell Excel series controllers as well as for Honeywell
individual room temperature controllers. These controllers
track the precise valve position by counting the number of
individual control pulses which move the valve from one
position to another. For this reason, the actuators do not need
endswitches or a feedback potentiometer. The absence of
these mechanical components ensures longtime reliability.
The M6410C/L and M7410C actuators are also compatible
with any controller providing intelligent position control and
having a built-in shut-off function.
These actuators are well suited for applications where space
is limited and minimum power consumption is required. The
actuators are both attractive and robust in design.
FEATURES
•Small size allows installation where space is limited
•Low power consumption
•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-off-point
•Reversible synchronous AC motor
•Suitable for three-position modulating control without
proportional feedback
•Supplied with pre-wired connection cable
•Simple, standardized valve/actuator coupling; no
tools required for mounting
•Visual valve position indicator furnished with
actuators
•Manual operation provided by the valve adjustment
cap, extra knob, or with a hexagon key
•Auxiliary switch

OPERATION
General
The movement of the electric actuators is produced by a
screw spindle which is driven in both directions by a syn-
chronous motor through a set of gears. A magnetic clutch
limits the torque of the gear assembly and the driving force of
the actuators. The actuators are fixed to the valve body by
means of a coupling ring requiring no tools for mounting. The
actuators are maintenance-free and supplied completely with
a ready-to-wire connecting cable.
MOUNTING POSITION
The actuator may only be mounted beside or above the valve.
Adjust the valve to the correct position before mounting the
actuator.
Fig. 1 Mounting positions
MOUNTING
Before the actuator is fixed to the valve, you must remove the
adjustment cap (Fig. 2). Make sure that the actuator is in the
retract position (factory-supplied position) before fixing the
actuator to the valve body.
Fig. 2 Remove protection cap
The actuator must be mounted by hand. Don't use tools or
additional force because actuator and valve may be
damaged.
Fig. 3 Mounting the actuator
ELECTRIC WIRING OF MOTOR
A fuse with a contact gap of at least 3 mm for each pole must
be fitted with the fixed installation. The fuse rate is max. 2 A.
The electrical installation must comply with the wiring diagram
shown in Fig. 4.
MANUAL OPERATION
The actuators with integrated manual operation (see table
"Versions") feature a hexagonal key hole for manual
operation. For more comfort, an additional knob for manual
adjustment is packed separately. To avoid damaging the
valve, separate the actuator from the power supply before
adjusting manually.

COMMISSIONING ADVICE
A functional check of the valve actuator can be carried out by
changing the controller setpoint by 5 °C or more. The move-
ment of the actuator stem (Fig. 6) indicates whether the valve
is opening or closing.

AUXILIARY SWITCHES
The actuators with the OS-number M*****40** feature two
auxiliary switches, each with its own cable. Auxiliary switch S1
switches when the stem reaches its fixed switchpoint.
Auxiliary switch S2 switches when the stem reaches its
adjustable switchpoint.

Adjustment of Auxiliary Switch2
Auxiliary switch 2 should be adjusted by a skilled person,
only.
Move the actuator to the position where the switch is to be
tripped. Cut the plastic skin with a sharp knife. Below the skin,
the adjustment screw can be accessed. Turn the screw
clockwise until the end stop is reached. Turn the screw
counterclockwise until the switch point is achieved. To check
that the required position has been set, move the actuator.
Finally, seal the adjustment hole with a piece of tape.

Electric Wiring of Auxiliary Switches
The electrical installation must comply with the wiring diagram
shown in Fig. 9. If the auxiliary switch is connected to
230 Vac, a switch with a contact gap of at least 3 mm for each
pole must be fitted with the installation.
